Nursing Elites

1. 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.

2. 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.

3. A client with a history of asthma and bronchitis arrives at the clinic with shortness of breath, productive cough with thickening mucus, and the inability to walk up a flight of stairs without experiencing breathlessness. Which action is most important for the nurse to instruct the client about self-care?

• A. Increase the daily intake of oral fluids to liquefy secretions
• B. Avoid crowded enclosed areas to reduce pathogen exposure
• C. Call the clinic if undesirable side effects of medications occur
• D. Teach anxiety reduction methods for feelings of suffocation

Correct answer: A

Rationale: Increasing fluid intake is crucial as it helps to thin mucus secretions, making them easier to expectorate. This can alleviate the client's symptoms of shortness of breath and productive cough. Option B is not the most important action in this scenario, as it does not directly address the client's respiratory distress. Option C, while important, focuses on medication side effects rather than addressing the immediate breathing difficulties. Option D, teaching anxiety reduction methods, is not the priority when the client's main concern is respiratory distress.

4. How often should the casts be changed for a newborn with talipes who is wearing casts?

• A. Daily
• B. Weekly
• C. Biweekly
• D. Monthly

Correct answer: B

Rationale: The correct answer is B: Weekly. Treatment of talipes involves manipulation and applying short leg casts. The casts need to be changed weekly to allow for further manipulation and to accommodate the rapid growth of the infant. Changing the casts daily (choice A) would be too frequent and may not provide enough time for the correction to take place. Changing the casts biweekly (choice C) or monthly (choice D) would not provide adequate support for the ongoing correction process required for talipes.

5. A client with rheumatoid arthritis has elevated serum rheumatoid factor. Which interpretation of this finding should the nurse make?

• A. Evidence of spread of the disease to the kidney.
• B. Confirmation of the autoimmune disease process.
• C. Representative of a decline in the client's condition.
• D. Indication of the onset of joint degeneration.

Correct answer: B

Rationale: The correct interpretation of elevated serum rheumatoid factor in a client with rheumatoid arthritis is confirmation of the autoimmune disease process. Rheumatoid factor is a marker for autoimmune activity, thus confirming the diagnosis of rheumatoid arthritis. Choice A is incorrect as elevated rheumatoid factor does not specifically indicate spread of the disease to the kidney. Choice C is incorrect as elevated rheumatoid factor does not always represent a decline in the client's condition. Choice D is incorrect as elevated rheumatoid factor is not an indication of the onset of joint degeneration, but rather points towards autoimmune activity.
