2.
What is the normal range for sodium?
Correct Answer
135-145
Explanation
The normal range for sodium in the body is 135-145. This range represents the optimal level of sodium concentration in the blood. Sodium plays a crucial role in maintaining fluid balance, transmitting nerve impulses, and supporting muscle function. Levels below 135 or above 145 can indicate an imbalance in the body, which may lead to various health issues. Therefore, it is important to keep sodium levels within this normal range for overall well-being.
3.
What is the normal range for K+?
Correct Answer
3.5-5.0
Explanation
The normal range for K+ is 3.5-5.0. This range represents the normal levels of potassium in the blood. Potassium is an essential electrolyte that plays a crucial role in various bodily functions, including maintaining proper heart and muscle function. Deviations from this range can indicate an imbalance in potassium levels, which can have negative health effects. Therefore, it is important to monitor and maintain K+ levels within the normal range.
4.
What is the normal range for calcium?
Correct Answer
8.5-10.5
Explanation
The normal range for calcium levels in the body is 8.5-10.5. This range represents the typical amount of calcium found in the blood and is considered to be within the normal range for healthy individuals. Calcium plays a crucial role in various bodily functions, including bone health, muscle contraction, and nerve function. Deviations from this range can indicate underlying health conditions, such as calcium deficiency or hypercalcemia. Regular monitoring of calcium levels is important to ensure optimal health.
5.
What is the normal range for magnesium?
Correct Answer
0.75-0.95
Explanation
The normal range for magnesium in the body is typically between 0.75 and 0.95. This range represents the optimal levels of magnesium that are considered healthy and necessary for various bodily functions. Magnesium plays a crucial role in maintaining normal muscle and nerve function, regulating blood sugar levels, and supporting a healthy immune system. Deviations from this normal range can indicate a magnesium deficiency or excess, which may lead to various health issues.
6.
What clues can be gained from an ECG?
Correct Answer
C. The electrical activity of the heart. Looking for a normal PQRST wave.
Explanation
An ECG (electrocardiogram) is a medical test that measures and records the electrical activity of the heart. It provides valuable clues about the heart's health and function. The presence of a normal PQRST wave on an ECG indicates that the electrical activity of the heart is normal. Abnormalities in the PQRST wave can suggest various heart conditions such as arrhythmias, heart attacks, or electrolyte imbalances. Therefore, analyzing the PQRST wave on an ECG can provide important information about the electrical activity of the heart.
7.
No screening for fluid and electrolyte imbalance is routine for the general population.
Correct Answer
A. True
Explanation
Screening for fluid and electrolyte imbalance is not a routine procedure for the general population. This means that individuals are not routinely tested or assessed for any imbalances in their fluid and electrolyte levels. Such screenings are typically only done if there is a specific medical concern or condition that warrants it. Therefore, the statement "No screening for fluid and electrolyte imbalance is routine for the general population" is true.
8.
What is a normal pH range?
Correct Answer
7.35-7.45
Explanation
The normal pH range is 7.35-7.45. pH is a measure of the acidity or alkalinity of a solution. A pH value below 7 indicates acidity, while a value above 7 indicates alkalinity. The normal pH range for human blood is slightly alkaline, between 7.35 and 7.45. This range is important for maintaining the proper functioning of bodily systems and enzymes. Any significant deviation from this range can indicate an underlying health issue and may require medical attention.
9.
What can cause respiratory acidosis?
Correct Answer
Retention of to much c02.
Explanation
Respiratory acidosis is caused by the retention of too much carbon dioxide (CO2) in the body. When there is an imbalance in the levels of CO2 and oxygen in the bloodstream, it leads to an increase in CO2 concentration, resulting in acidosis. This can occur due to various factors such as hypoventilation, lung diseases, respiratory muscle weakness, or impaired gas exchange. In these conditions, the body fails to eliminate CO2 effectively, leading to an accumulation and subsequent acidification of the blood.
10.
What causes metabolic acidosis?
Correct Answer
B. Too much H+ retention, or HCO3 loss
Explanation
Metabolic acidosis occurs when there is an excess of hydrogen ion (H+) retention or a loss of bicarbonate (HCO3-). This imbalance can be caused by various factors such as kidney disease, diabetes, excessive alcohol consumption, or certain medications. When there is an increase in H+ or a decrease in HCO3-, the pH of the blood decreases, leading to acidosis. This can disrupt normal bodily functions and may result in symptoms such as rapid breathing, confusion, and fatigue.
11.
Respiratory alkalosis can be caused from?
Correct Answer
C. Too much CO2 loss
Explanation
Respiratory alkalosis occurs when there is an excessive loss of carbon dioxide (CO2) from the body. CO2 is an acidic compound, and when it is lost in excess, it leads to a decrease in the concentration of hydrogen ions (H+), causing the blood pH to increase and become more alkaline. This can happen in situations such as hyperventilation, where there is rapid and deep breathing, leading to excessive elimination of CO2. Therefore, too much CO2 loss is a valid explanation for the occurrence of respiratory alkalosis.
12.
At which age should BP screenings begin?
Correct Answer
D. 20
Explanation
BP screenings should begin at the age of 20. This is because high blood pressure (BP) can develop at any age, including during early adulthood. Regular screenings help in detecting any abnormalities in blood pressure levels and allow for early intervention and management of hypertension. Starting screenings at 20 years old ensures that individuals are proactive in monitoring their BP and taking necessary steps to maintain a healthy cardiovascular system.
13.
The anterior pituitary gland secrets which main hormone?
Correct Answer
B. Thyroid, FSH, GH
Explanation
The anterior pituitary gland secretes the hormones Thyroid, FSH (Follicle-stimulating hormone), and GH (Growth hormone). These hormones play important roles in regulating various bodily functions. The thyroid hormone is responsible for controlling metabolism, FSH is involved in the regulation of reproductive processes, and GH is essential for growth and development.
14.
The posterior pituitary gland secrets?
Correct Answer
A. ADH, which causes na and water retention
Explanation
The posterior pituitary gland secretes ADH, also known as antidiuretic hormone. ADH plays a crucial role in regulating the body's water balance by increasing water reabsorption in the kidneys. It also causes sodium retention, which helps maintain the body's electrolyte balance. Therefore, the correct answer is ADH, which causes sodium and water retention.
15.
Normal range for HC03
Correct Answer
22-26
Explanation
The normal range for HC03 (bicarbonate) levels in the body is 22-26. Bicarbonate is an important electrolyte that helps regulate the pH balance in the blood. A level below 22 may indicate metabolic acidosis, while a level above 26 may indicate metabolic alkalosis. Therefore, a range of 22-26 is considered normal for HC03 levels.
16.
Normal range for paco2
Correct Answer
35-45
Explanation
The normal range for PaCO2 (partial pressure of carbon dioxide in arterial blood) is 35-45 mmHg. This range indicates the typical levels of carbon dioxide in the blood, which is important for maintaining the body's acid-base balance. Values below or above this range may indicate respiratory alkalosis or acidosis, respectively. Monitoring PaCO2 levels can help assess lung function and the effectiveness of ventilation.
