1. Which vitamin deficiency is most associated with night blindness?

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

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

2. Which of the following is NOT a second-line agent used for the treatment of Tuberculosis?

• A. Amikacin
• B. Moxifloxacin
• C. Rifabutin
• D. Cycloserine

Correct answer: C

Rationale: The correct answer is C, Rifabutin. Rifabutin is actually a first-line drug used in the treatment of tuberculosis. Choices A, B, and D (Amikacin, Moxifloxacin, and Cycloserine) are considered second-line agents for tuberculosis treatment. These drugs are used when the first-line medications are either ineffective or cannot be tolerated by the patient.

3. A child with glomerulonephritis is admitted in the acute edematous phase. Based on this diagnosis, which nursing intervention should the nurse plan to include in the child's plan of care?

• A. Recommend parents bring favorite snacks
• B. Encourage ambulation daily to the playroom
• C. Measure blood pressure every 4 to 6 hours
• D. Offer a selection of fresh fruit for each meal

Correct answer: C

Rationale: The correct answer is to measure blood pressure every 4 to 6 hours. Monitoring blood pressure frequently is crucial in managing glomerulonephritis, as hypertension is a common complication during the acute edematous phase. Choice A is incorrect as it does not address the specific needs of a child with glomerulonephritis. Choice B is incorrect as excessive activity may not be suitable during the acute phase, as rest and monitoring are more important. Choice D is incorrect as the focus should be on monitoring vital signs rather than meal options.

4. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

• A. Parathyroid hormone
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.

5. A male client who has been diagnosed with schizophrenia is withdrawn, isolates himself in the day room, and answers questions with one or two-word responses. This morning, the practical nurse observes that he is diaphoretic and is pacing in the hall. Which intervention is most important for the PN to implement?

• A. Persuade the client to lie down
• B. Provide a drink high in electrolytes
• C. Observe the client during the shift
• D. Measure appropriate vital signs

Correct answer: D

Rationale: Measuring vital signs is crucial in this situation as it helps to determine if the client is experiencing a physical health issue or if the symptoms are related to a mental health crisis, such as anxiety or agitation. The presence of diaphoresis and pacing may indicate physiological changes requiring immediate attention. Providing a drink high in electrolytes or persuading the client to lie down may not address the underlying cause of the symptoms. Simply observing the client during the shift without taking necessary actions to assess his physiological status may delay appropriate intervention.
