Explanation
The intracellular fluid compartment refers to the fluid found inside the cells of the body. It is the largest compartment and makes up approximately 70% of the body fluid. This fluid is essential for maintaining cell function and carrying out various cellular processes. It contains important electrolytes and nutrients that are necessary for cell survival and proper functioning. The intracellular fluid compartment is separate from the extracellular fluid compartment, which includes interstitial fluid and intravascular fluid.
2.
Controls the actual fluid intake
Correct Answer
C. Thirst
Explanation
Thirst is the sensation that prompts an individual to drink fluids. It is the body's way of signaling that it needs more water. When the body becomes dehydrated or needs to regulate its fluid balance, the brain triggers the sensation of thirst, prompting the person to drink water or other fluids. This mechanism helps to control the actual fluid intake in the body and maintain proper hydration levels. The kidneys, hunger, and feces do not directly control fluid intake, making them incorrect options.

9.
This causes shifting of fluids from the ICF to ECF. The cells shrink.
Correct Answer
A. Dehydration
Explanation
Dehydration is the correct answer because when there is a lack of fluid intake or excessive fluid loss, the body becomes dehydrated. This leads to a shift of fluids from the intracellular fluid (ICF) to the extracellular fluid (ECF) in an attempt to maintain proper fluid balance. As a result, the cells shrink due to the loss of water. Symptoms of dehydration may include dry mouth, increased thirst, fatigue, dizziness, and decreased urine output (oliguria).
10.
The best indicator for edema.
Correct Answer
B. Weight gain
Explanation
Weight gain is the best indicator for edema because edema is the accumulation of excess fluid in the body's tissues, leading to swelling. When a person experiences edema, their body retains fluid, resulting in an increase in weight. Therefore, weight gain is a clear indication of edema as it reflects the accumulation of fluid in the body.
11.
What is the rationale in allowing the client breath into the plastic bag or brown paper bag?
Correct Answer
B. To reinhale the exhaled carbon dioxide
Explanation
Allowing the client to breathe into a plastic bag or brown paper bag is done to reinhale the exhaled carbon dioxide. When a person breathes into a bag, they are inhaling the carbon dioxide they just exhaled. This can help increase the levels of carbon dioxide in the body, which can be beneficial in certain medical situations. It is important to note that this technique should only be used under the guidance of a healthcare professional.
12.
It is caused by failure of the respiratory system to remove carbon dioxide from the body fluid produced in the tissues.
Correct Answer
Respiratory Acidosis
Explanation
Respiratory acidosis occurs when the respiratory system fails to effectively remove carbon dioxide from the body fluids produced in the tissues. This can happen due to various reasons such as lung diseases, airway obstruction, or respiratory muscle weakness. When carbon dioxide builds up in the body, it combines with water to form carbonic acid, leading to an increase in acidity in the blood. This condition can cause symptoms like shortness of breath, confusion, and fatigue. Treatment usually involves addressing the underlying cause and improving respiratory function to remove excess carbon dioxide from the body.
13.
It is caused by loss of carbon dioxide from the lungs at a faster rate that it is produced in the tissues.
Correct Answer
Respiratory Alkalosis
Explanation
Respiratory alkalosis occurs when there is excessive elimination of carbon dioxide from the lungs, leading to a decrease in carbon dioxide levels in the blood. This can be caused by hyperventilation, which results in rapid breathing and a higher rate of carbon dioxide removal from the body. As a result, the pH of the blood increases, becoming more alkaline. Symptoms of respiratory alkalosis may include dizziness, lightheadedness, tingling in the extremities, and muscle spasms.
14.
Results from abnormal accumulation of fixed acids or loss of base.
Correct Answer
Metabolic Acidosis
Explanation
Metabolic acidosis refers to a condition characterized by an abnormal buildup of fixed acids or loss of base in the body, leading to an imbalance in the acid-base levels. This can occur due to various factors such as excessive production of acids, impaired elimination of acids by the kidneys, or loss of bicarbonate, a base that helps regulate acidity. Metabolic acidosis can result in symptoms like rapid breathing, confusion, fatigue, and can be caused by conditions like kidney disease, diabetes, or certain medications. Therefore, the given answer, "Metabolic Acidosis," accurately describes the condition resulting from abnormal accumulation of fixed acids or loss of base.
15.
Results from loss of hydrogen ions or addition of base to body fluids.
Correct Answer
Metabolic Alkalosis
Explanation
Metabolic alkalosis is a condition characterized by an increase in the pH of body fluids, caused by either a loss of hydrogen ions or an excess of base in the body. This can occur due to various factors such as vomiting, excessive use of diuretics, or excessive intake of antacids. When hydrogen ions are lost or when base is added to the body fluids, the balance of acids and bases is disrupted, leading to an alkaline pH. This condition can have various symptoms such as muscle twitching, nausea, and confusion. Treatment involves addressing the underlying cause and restoring the acid-base balance.
16.
Select all that results to Respiratory and Metabolic Acidosis
Correct Answer(s)
A. Hyperkalemia
C. Increased BP
D. CNS depression
Explanation
Hyperkalemia, increased blood pressure, and CNS depression can all result in respiratory and metabolic acidosis. Hyperkalemia, an increased level of potassium in the blood, can cause acidosis by impairing kidney function and reducing the excretion of acid. Increased blood pressure can lead to acidosis by causing vasoconstriction and reducing blood flow to the kidneys, impairing their ability to excrete acid. CNS depression can also contribute to acidosis by reducing the respiratory drive and causing hypoventilation, leading to an accumulation of carbon dioxide and subsequent acidosis.
17.
Select all that results to Respiratory and Metabolic Alkalosis
Correct Answer(s)
A. Increased ICP
C. Hypotension
D. Seizures
Explanation
Increased intracranial pressure (ICP) can lead to respiratory alkalosis due to hyperventilation caused by brainstem compression. Hypotension can cause decreased perfusion to the brain, leading to cerebral hypoxia and subsequent respiratory alkalosis. Seizures can also cause hyperventilation and respiratory alkalosis. Therefore, all three options (Increased ICP, hypotension, seizures) can result in both respiratory and metabolic alkalosis. Hyperkalemia, on the other hand, is not directly related to alkalosis and does not cause hyperventilation.
18.
Select the vital signs during dehydration
Correct Answer(s)
A. Increased body temperature
C. Increased respiratory rate
D. Decreased blood pressure
Explanation
During dehydration, the body tries to compensate for the lack of fluids by increasing its temperature. This is because sweating, which helps regulate body temperature, becomes less effective when there is a lack of water. Additionally, dehydration can lead to an increased respiratory rate as the body tries to compensate for the reduced oxygen levels. Lastly, dehydration causes a decrease in blood volume, leading to a decrease in blood pressure. Therefore, the vital signs during dehydration include increased body temperature, increased respiratory rate, and decreased blood pressure.
19.
Select the clinical manifestations of edema
Correct Answer(s)
A. Cool, pale skin
B. Weeping edema
C. Neck vein engorgement
Explanation
The clinical manifestations of edema include cool, pale skin, weeping edema, and neck vein engorgement. Cool, pale skin can be a sign of poor circulation due to fluid accumulation. Weeping edema refers to the excessive fluid leaking from the skin. Neck vein engorgement occurs when the veins in the neck become swollen due to increased fluid volume. Weight loss, on the other hand, is not typically associated with edema but may be a symptom of other conditions.
20.
Select all the manifestations for Hyperkalemia
Correct Answer(s)
A. Irritability
B. Flaccid paralysis
C. Ventricular fibrillation
Explanation
Hyperkalemia is a condition characterized by high levels of potassium in the blood. Manifestations of hyperkalemia include irritability, flaccid paralysis, and ventricular fibrillation. Irritability is a common symptom and is often the first sign of hyperkalemia. Flaccid paralysis can occur due to the effect of high potassium levels on muscle function. Ventricular fibrillation is a life-threatening arrhythmia that can result from severe hyperkalemia. Hypotension, or low blood pressure, is not typically associated with hyperkalemia and is therefore not a manifestation of this condition.
21.
The percentage of water in an infant is?
Correct Answer
A. 80%
Explanation
The correct answer is 80%. This is because infants have a higher percentage of water in their bodies compared to adults. Water is essential for the proper functioning of the body, and infants have a higher water content to support their rapid growth and development.
22.
What is the management for water intoxication?
Correct Answer
A. Fluid restriction
Explanation
Fluid restriction is the management for water intoxication because it involves limiting the intake of fluids to prevent further dilution of electrolytes in the body. Water intoxication occurs when there is an excessive intake of water, leading to an imbalance of electrolytes and potentially dangerous symptoms. By restricting fluid intake, the body can gradually restore the electrolyte balance and prevent further complications. This management approach is crucial in treating water intoxication and ensuring the patient's safety.
23.
The accumulation of fluids in the interstitial spaces.
Correct Answer
B. Edema
Explanation
Edema refers to the accumulation of fluids in the interstitial spaces, which are the spaces between cells in the body. This can occur due to various reasons, such as an increase in capillary permeability, impaired lymphatic drainage, or increased fluid retention. Hypoalbuminemia, which is a low level of albumin in the blood, can contribute to the development of edema. Edema can also be caused by other factors like heart failure, kidney disease, or certain medications. Therefore, edema is the correct answer in this case.
24.
What is the rationale in elevating the edematous body part?
Correct Answer
D. To promote venous return
Explanation
Elevating an edematous body part helps to promote venous return. When a body part becomes edematous, it means there is an accumulation of excess fluid in the tissues. By elevating the edematous body part, gravity assists in reducing the pooling of blood and fluid in the area, allowing it to flow back towards the heart more easily. This helps to improve circulation, reduce swelling, and promote healing.
25.
What is the management for Hypernatremia?
Correct Answer
C. Restrict sodium in the diet
Explanation
Restricting sodium in the diet is the appropriate management for hypernatremia. Hypernatremia is a condition characterized by high levels of sodium in the blood. Restricting sodium intake helps to lower the sodium levels in the body, which is essential for managing this condition. This can be achieved by avoiding foods that are high in sodium and opting for a low-sodium diet. By restricting sodium in the diet, the body's sodium levels can be brought back to normal, thus effectively managing hypernatremia.
