Nursing Elites

1. A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?

• A. Osmolarity
• B. Glucose
• C. Albumin
• D. Platelets

Correct answer: B

Rationale: The correct answer is B: Glucose. Hydrocortisone can lead to increased blood glucose levels, so monitoring glucose is crucial to assess for hyperglycemia, a common side effect of corticosteroid therapy. Monitoring osmolarity (choice A) is not typically indicated in this scenario. Albumin (choice C) and platelets (choice D) are not directly affected by hydrocortisone therapy and are not the primary focus of monitoring in this case.

2. What are early signs of varicella disease?

• A. High fever over 101°F (38.3°C)
• B. General malaise
• C. Increased appetite
• D. Crusty sores

Correct answer: B

Rationale: The correct early sign of varicella disease is general malaise. During the prodromal period, patients may experience low-grade fever, malaise, and anorexia. Increased appetite and crusty sores are not typically early signs of varicella. The appearance of lesions occurs later in the course of the disease.

3. A client who has a history of unstable angina is admitted to the emergency department with chest pain.

• A. Chest pain relieved by rest.
• B. Chest pain unrelieved after taking 3 sequential nitroglycerin tablets.
• C. Chest pain occurring only with exertion.
• D. Chest pain lasting less than 5 minutes.

Correct answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.

4. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?

• A. 16 ml/hour.
• B. 18 ml/hour.
• C. 20 ml/hour.
• D. 22 ml/hour.

Correct answer: C

Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

5. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?

• A. When the fever dissipates
• B. After the incubation period
• C. When the lesions have healed
• D. When the lesions are crusted over

Correct answer: D

Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.
