1. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: B

Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.

2. Which test is used to monitor the degree of blood glucose control over a long period?

• A. Glucose tolerance test
• B. Glycated hemoglobin level
• C. Self-monitoring of blood glucose
• D. 24-hour urinary glucose excretion

Correct answer: B

Rationale: The correct answer is B, glycated hemoglobin level. The glycated hemoglobin (HbA1c) test measures the average blood glucose levels over the past 2-3 months, providing a long-term picture of glucose control. Choice A, the glucose tolerance test, measures how well your body processes glucose but is not specifically for long-term monitoring. Choice C, self-monitoring of blood glucose, involves daily testing by individuals, providing immediate rather than long-term information. Choice D, 24-hour urinary glucose excretion, measures the amount of glucose excreted in the urine over 24 hours and is not typically used for long-term monitoring of blood glucose control.

3. In administering blood transfusion, what needle gauge is used?

• A. 18 C. 23
• B. 22 D. 24
• C.
• D.

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

5. A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?

• A. Formula that remains in the bottle should not be used for one more feeding.
• B. Formula should be changed to whole milk when the infant is 12 months old.
• C. If the infant is gaining weight too rapidly, do not dilute the formula.
• D. If the infant turns away after taking most of the feeding, stop the feeding.

Correct answer: D

Rationale: If the infant turns away after taking most of the feeding, it indicates they are full, and continuing to feed may lead to overfeeding. Choice A is incorrect because it is not safe to use formula that remains in the bottle for another feeding due to the risk of bacterial contamination. Choice B is incorrect as whole milk should be introduced after the infant is 12 months old, not 9 months old. Choice C is incorrect as diluting formula can compromise the infant's nutrition and should not be done without healthcare provider guidance.
