1. 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.

2. How is the stomach protected from damage by gastric acid?

• A. enzymes present in the stomach
• B. a protective bacteria in the stomach
• C. bicarbonate present in the stomach
• D. the mucus lining of the stomach

Correct answer: D

Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.

3. 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.

4. Which nutrient is critical for wound healing and immune function?

• A. Vitamin B12
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: Vitamin C is essential for collagen formation and immune function.

5. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: D

Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.
