Nursing Elites

1. 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.

2. 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.

3. 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.

4. Ten hours following thrombolysis for an ST elevation myocardial infarction (STEMI), a client is receiving a lidocaine infusion for isolated runs of ventricular tachycardia. Which finding should the nurse document in the EMR as a therapeutic response to the lidocaine infusion?

• A. Stabilization of BP ranges
• B. Cessation of chest pain
• C. Reduced heart rate
• D. Decreased frequency of episodes of VT

Correct answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.

5. How should the nurse measure urinary output for an infant with dehydration?

• A. Attaching a urine collecting bag
• B. Wringing out the diaper
• C. Weighing the diaper
• D. Inserting a catheter

Correct answer: C

Rationale: The correct way to measure urinary output for an infant with dehydration is by weighing the diaper. Wet diapers are weighed to assess the amount of output accurately. Attaching a urine collecting bag and inserting a catheter are invasive methods not typically used for routine measurement of urinary output in infants. Wringing out the diaper can lead to inaccurate measurements and is not a recommended method for assessing urinary output.
