Which one of the following is NOT a function of the Upper airway?
Correct Answer
A. For clearance mechanism such as coughing
Explanation
The upper airway is responsible for warming, filtering, and humidifying inspired air, as well as protecting the lower airway from foreign matter. However, it is not directly involved in clearance mechanisms such as coughing. Coughing is a reflex action that occurs in the lower airway to remove any foreign material or excess mucus.
2.
It is the hair the lines the vestibule which function as a filtering mechanism for foreign objects
Correct Answer
D. Vibrissae
Explanation
Vibrissae are specialized hairs that line the vestibule of certain animals, including mammals. They function as a filtering mechanism for foreign objects, such as dust or debris, that may enter the nasal passages. These long, stiff hairs are highly sensitive and can detect even slight movements in the surrounding air, allowing animals to navigate and avoid obstacles in dark or narrow spaces. Vibrissae are particularly well-developed in animals like rats and cats, where they play a crucial role in their sensory perception and spatial awareness.

Goblet cells are responsible for secreting mucus that helps protect the lungs by trapping debris in the respiratory tract. Mucus acts as a sticky barrier, trapping particles such as dust, bacteria, and viruses, preventing them from reaching the lungs and causing damage or infection. Goblet cells are found in the respiratory epithelium and are specialized in producing and secreting mucus to maintain the health and integrity of the respiratory system.
7.
How many lobes are there in the RIGHT LUNG?
Correct Answer
C. Three
Explanation
The right lung is divided into three lobes: the superior, middle, and inferior lobes. Each lobe has its own blood supply and is responsible for specific functions in the respiratory system. The lobes of the right lung allow for efficient oxygen exchange and help in maintaining proper lung function.
8.
The presence of the liver causes which anatomical difference of the Kidneys and the Lungs?
Correct Answer
C. Right kidney lower, Right lung shorter
Explanation
The presence of the liver causes the right kidney to be positioned lower than the left kidney. This is because the liver takes up space on the right side of the abdominal cavity, pushing the right kidney down. Additionally, the right lung is slightly shorter than the left lung due to the liver occupying space in the right thoracic cavity, restricting the lung's expansion.
9.
Surfactant is produced by what cells in the alveoli?
Correct Answer
B. Type II pneumocytes
Explanation
Surfactant is a substance that helps reduce surface tension in the alveoli, preventing them from collapsing. Type II pneumocytes are responsible for producing surfactant in the alveoli. These cells secrete surfactant to keep the alveoli open and facilitate efficient gas exchange in the lungs. Type I pneumocytes, on the other hand, are involved in the actual gas exchange process, while goblet cells produce mucus in the airways and adipose cells store fat.

It provides the correct information that humans need 21% of oxygen and that the air contains 21% oxygen, indicating that the available oxygen meets the human requirement.
16.
Which of the following is TRUE about Expiration?
Correct Answer
A. A passive process
Explanation
Expiration is the process of exhaling air from the lungs. It is considered a passive process because it does not require any active muscle contraction. The diaphragm and other respiratory muscles relax, allowing the elastic recoil of the lungs and chest wall to push the air out. The length of expiration is typically longer than inspiration, and stridor, a high-pitched wheezing sound, is not commonly heard during expiration. No energy is required for expiration to occur.
17.
Which of the following is TRUE in postural drainage?
Correct Answer
A. Patient assumes position for 10 to 15 minutes
Explanation
Postural drainage is a technique used to help mobilize and remove secretions from the lungs. The correct answer states that the patient assumes a specific position for 10 to 15 minutes. This is true because during postural drainage, the patient is positioned in a way that allows gravity to assist in moving secretions from the lungs to the larger airways, where they can be coughed up or suctioned out. This position is typically held for a specific duration to ensure adequate drainage.
18.
All but one of the following is a purpose of steam inhalation
Correct Answer
D. Promote bronchoconstriction
Explanation
Steam inhalation is a common home remedy used to relieve congestion and respiratory symptoms. It involves inhaling warm, moist air, which can help to loosen mucus and soothe irritated airways. However, promoting bronchoconstriction, which is the narrowing of the airways, is not a purpose of steam inhalation. In fact, steam inhalation is often used to alleviate bronchoconstriction and improve breathing. Therefore, the correct answer is "Promote bronchoconstriction."
19.
Which of the following is NOT TRUE in steam inhalation?
Correct Answer
C. Render steam inhalation for atleast 60 minutes
20.
When should a nurse suction a client?
Correct Answer
B. As needed
Explanation
A nurse should suction a client as needed. Suctioning is a procedure used to remove secretions or obstructions from the airway to maintain a clear passage for breathing. The need for suctioning can vary depending on the client's condition and symptoms. It is not necessary to suction a client at fixed time intervals such as every 1 hour or every 4 hours, as this may cause unnecessary discomfort and potential harm to the client. Instead, the nurse should assess the client's respiratory status and only perform suctioning when there are indications of airway obstruction or excessive secretions.
21.

Which of the following, if done by the nurse, indicates incompetence during suctioning an unconscious client?
Correct Answer
A. Measure the length of the suction catheter to be inserted by measuring from the tip of the nose, to the earlobe, to the xipHoid process
Explanation
The nurse measuring the length of the suction catheter by measuring from the tip of the nose to the earlobe to the xiphoid process indicates incompetence during suctioning an unconscious client because this is an incorrect method of measuring the length of the catheter. The correct method is to measure from the tip of the nose to the earlobe and then to the angle of the jaw. Measuring to the xiphoid process is not necessary and may result in the catheter being inserted too far into the airway.
26.
Which of the following is the initial sign of hypoxemia in an adult client?1. Tachypnea2. Tachycardia3. Cyanosis4. Pallor5. Irritability6. Flaring of Nares
Correct Answer
B. 2,5
Explanation
Tachycardia and irritability are the initial signs of hypoxemia in an adult client. Tachycardia refers to an abnormally fast heart rate, which can occur in response to a decrease in oxygen levels in the body. Irritability is a common symptom that can be caused by hypoxemia, as the brain may not be receiving enough oxygen. These signs can be early indicators of hypoxemia and should be monitored closely in order to provide appropriate medical intervention.
27.
Which method of oxygenation least likely produces anxiety and apprehension?
Correct Answer
A. Nasal Cannula
Explanation
The nasal cannula is the method of oxygenation that least likely produces anxiety and apprehension because it is the most comfortable and least invasive option. It delivers low to moderate levels of oxygen through two small prongs that sit in the nostrils, allowing the patient to breathe normally. The nasal cannula does not cover the face or restrict movement, which can help alleviate anxiety and apprehension. In contrast, the other options (simple face mask, non-rebreather mask, and partial rebreather mask) cover the nose and mouth, which may cause discomfort and make breathing feel more restricted, potentially leading to increased anxiety and apprehension.
28.
Which of the following oxygen delivery method can deliver 100% Oxygen at 15 LPM?
Correct Answer
C. Non Rebreather mask
Explanation
A non-rebreather mask is capable of delivering 100% oxygen at a flow rate of 15 LPM. This type of mask has a reservoir bag attached to it, which allows the patient to inhale a higher concentration of oxygen with each breath. The mask also has one-way valves that prevent the patient from rebreathing exhaled air, ensuring that they receive a continuous supply of fresh oxygen. This makes the non-rebreather mask an effective method for delivering high concentrations of oxygen to patients in need.
29.
Which of the following is not true about OXYGEN?
Correct Answer
D. Excessive oxygen administration results in respiratory acidosis
Explanation
Excessive oxygen administration results in respiratory acidosis. This means that when too much oxygen is administered, it can lead to a condition called respiratory acidosis, where there is an accumulation of carbon dioxide in the body, causing a decrease in blood pH. This is the opposite of what oxygen is typically known for, which is supporting combustion and being odorless, tasteless, and colorless.

Mang dagul, a 50 year old chronic smoker was brought to the E.R because of difficulty in breathing. Pleural effusion was the diagnosis and CTT was ordered. What does C.T.T Stands for?
Correct Answer
C. Closed tube thoracotomy
Explanation
CTT stands for Closed tube thoracotomy. In this scenario, the patient has been diagnosed with pleural effusion, which is the accumulation of fluid in the pleural space around the lungs. A closed tube thoracotomy is a surgical procedure where a chest tube is inserted into the pleural space to drain the fluid and relieve the pressure on the lungs, allowing the patient to breathe more easily. This procedure is commonly performed in cases of pleural effusion to improve respiratory function.
35.
Where will the CTT be inserted if we are to drain fluids accumulated in Mang dagul’s pleura?
Correct Answer
D. 8th ICS
Explanation
The correct answer is 8th ICS. The intercostal space (ICS) refers to the space between two adjacent ribs. In this case, the CTT (chest tube thoracostomy) will be inserted in the 8th ICS to drain fluids accumulated in Mang dagul's pleura. The pleura is the membrane that lines the chest cavity and covers the lungs. By inserting the CTT in the 8th ICS, it allows for effective drainage of the accumulated fluids from the pleural space to relieve any potential complications or discomfort.
36.
There is a continuous bubbling in the water sealed drainage system with suction. And oscillation is observed. As a nurse, what should you do?
Correct Answer
A. Consider this as normal findings
Explanation
In this scenario, the correct answer is to consider the continuous bubbling and oscillation in the water sealed drainage system with suction as normal findings. This is because the water sealed drainage system is designed to create bubbling and oscillation as a means of maintaining proper suction and preventing air from entering the system. Therefore, as a nurse, there is no need to be alarmed or take any further action in response to these observations.
37.
Which of the following is true about nutrition?
Correct Answer
D. It is the study of nutrients and the process in which they are use by the body
Explanation
Nutrition is the study of nutrients and the process in which they are used by the body. It involves understanding the different types of nutrients, such as proteins, fats, minerals, vitamins, and carbohydrates, and how they are broken down and utilized by the body for growth, development, energy production, and tissue repair.
38.
The majority of the digestion processes take place in the
Correct Answer
B. Small intestine
Explanation
The majority of digestion processes take place in the small intestine. This is because the small intestine is responsible for breaking down food into smaller molecules, such as carbohydrates, proteins, and fats, through the action of digestive enzymes. It also absorbs the nutrients from the digested food into the bloodstream for distribution to the rest of the body. The mouth starts the process of digestion by breaking down food mechanically through chewing and mixing it with saliva, but the actual breakdown of nutrients occurs primarily in the small intestine. The stomach plays a role in digestion by secreting gastric juices and breaking down proteins, but it is not where the majority of digestion takes place. The large intestine mainly absorbs water and electrolytes from the remaining undigested food, but it is not involved in the majority of digestion processes.
39.
All of the following is true about digestion that occurs in the Mouth except
Correct Answer
C. The action of ptyalin or the salivary tyrpsin breaks down starches into maltose
Explanation
The action of ptyalin or the salivary tyrpsin breaks down starches into maltose.
40.
Which of the following foods lowers the cardiac sphincter pressure?
Correct Answer
D. Coffee with coffee mate, Bacon and Egg
Explanation
Coffee with coffee mate, Bacon and Egg can lower the cardiac sphincter pressure. The cardiac sphincter is a muscle that separates the stomach from the esophagus and helps prevent stomach acid from flowing back into the esophagus. Certain foods can weaken this muscle and increase the risk of acid reflux. Coffee, especially when consumed with high-fat foods like bacon and eggs, can relax the cardiac sphincter and lead to acid reflux symptoms. Additionally, coffee mate, which is a non-dairy creamer, may also contribute to this effect.
41.
Where does the digestion of carbohydrates start?
Correct Answer
A. Mouth
Explanation
The digestion of carbohydrates starts in the mouth. Salivary amylase, an enzyme present in saliva, begins breaking down complex carbohydrates into simpler sugars like maltose. This initial breakdown of carbohydrates in the mouth is the first step in the digestive process, allowing for easier absorption and utilization of carbohydrates by the body.
42.
Protein and Fat digestion begins where?
Correct Answer
D. Stomach
Explanation
Protein and fat digestion begins in the stomach. The stomach produces gastric juice, which contains enzymes like pepsin that break down proteins into smaller peptides. Additionally, the stomach secretes gastric lipase, an enzyme that begins the breakdown of fats. This initial digestion in the stomach prepares the proteins and fats for further breakdown and absorption in the small intestine. The mouth and esophagus primarily play a role in the mechanical digestion of food, while the small intestine is mainly responsible for the absorption of nutrients.
43.
All but one is true about digestion that occurs in the Stomach
Correct Answer
C. HCl inhibits absorption of Calcium in the gastric mucosa
Explanation
HCl inhibits the absorption of calcium in the gastric mucosa. This means that when HCl is present in the stomach, it prevents the absorption of calcium from the food that is being digested. This can have implications for calcium levels in the body, as it may lead to decreased calcium absorption and potentially contribute to calcium deficiencies or imbalances. It is important for the body to regulate calcium absorption in order to maintain proper bone health and other physiological functions.
44.
Which of the following is NOT an enzyme secreted by the small intestine?
Correct Answer
C. Amylase
Explanation
Amylase is not an enzyme secreted by the small intestine. It is an enzyme produced primarily in the salivary glands and pancreas. Amylase is responsible for breaking down complex carbohydrates into simpler sugars. In the small intestine, other enzymes like sucrase and enterokinase are secreted. Sucrase aids in the digestion of sucrose, while enterokinase activates trypsinogen, an inactive enzyme produced in the pancreas, into trypsin, which helps in the digestion of proteins.
45.
The hormone secreted by the Small intestine that stimulates the production of pancreatic juice which primarily aids in buffering the acidic bolus passed by the Stomach
Correct Answer
C. Pancreozymin
Explanation
Pancreozymin is the correct answer because it is a hormone secreted by the small intestine that stimulates the production of pancreatic juice. Pancreatic juice aids in buffering the acidic bolus passed by the stomach, helping to neutralize the acidity and create a more favorable environment for digestion in the small intestine.
46.
When the duodenal enzyme sucrase acts on SUCROSE, which 2 monosaccharides are formed?
Correct Answer
B. Glucose + Fructose
Explanation
When the duodenal enzyme sucrase acts on sucrose, it breaks it down into two monosaccharides: glucose and fructose. This is because sucrase specifically hydrolyzes the glycosidic bond between glucose and fructose in sucrose, resulting in the formation of these two monosaccharides.
47.
This is the enzyme secreted by the pancrease that completes the protein digestion
Correct Answer
A. Trypsin
Explanation
Trypsin is an enzyme secreted by the pancreas that plays a crucial role in completing protein digestion. It helps break down proteins into smaller peptides and amino acids, which can then be absorbed by the body. Enterokinase is an enzyme that activates trypsinogen to form trypsin. Enterogastrone is a hormone that regulates the movement of food through the digestive system. Amylase is an enzyme that aids in the digestion of carbohydrates, not proteins. Therefore, the correct answer is Trypsin.
48.
The end product of protein digestion or the “Building blocks of Protein” is what we call
Correct Answer
D. Amino Acids
Explanation
Amino acids are the end product of protein digestion. Proteins are broken down into their individual amino acid components during the process of digestion. These amino acids are then used by the body to build new proteins, repair tissues, and perform various other functions. Nucleotides are the building blocks of DNA and RNA, not proteins. Fatty acids are the building blocks of lipids, not proteins. Glucose is a type of sugar and is not directly related to protein digestion.
49.
Enzyme secreted by the small intestine after it detects a bolus of fatty food. This will contract the gallbladder to secrete bile and relax the sphincter of Oddi to aid in the emulsification of fats and its digestion.
Correct Answer
C. Cholecystokinin
Explanation
Cholecystokinin is the correct answer because it is a hormone that is secreted by the small intestine in response to the presence of fatty food. It stimulates the contraction of the gallbladder, causing it to release bile, which aids in the emulsification of fats. Cholecystokinin also relaxes the sphincter of Oddi, allowing the bile to flow into the small intestine and aid in the digestion of fats. Therefore, cholecystokinin plays a crucial role in the digestion of fatty foods.
50.
Which of the following is not true about the Large Intestine?
Correct Answer
C. It is a sterile body cavity
Explanation
The large intestine is not a sterile body cavity. It contains a large number of bacteria that play a crucial role in the digestion and absorption of nutrients. These bacteria also produce certain vitamins, such as vitamin K. Therefore, the statement that the large intestine is a sterile body cavity is not true.
