A woman in labor receives meperidine (Demerol) for pain. The nurse caring for the infant will observe the infant closely for:

Respiratory Depression

Hypothyroidism

Tremors and Hyperreflexia

Congenital Anomalies

Answer and Explanation

The Correct Answer is A

Choice A reason: Meperidine, an opioid, crosses the placenta, risking neonatal respiratory depression. Monitoring breathing is critical post-delivery, making this the correct observation for the infant.

Choice B reason: Hypothyroidism is not associated with meperidine exposure. Opioids primarily affect respiration, so this is irrelevant and incorrect for the expected effect.

Choice C reason: Tremors and hyperreflexia are not typical meperidine effects in newborns; respiratory depression is the primary concern. This is incorrect for the nurse’s focus.

Choice D reason: Congenital anomalies result from chronic exposure, not acute labor analgesia. Meperidine’s immediate risk is respiratory, so this is incorrect for monitoring.

Correct Answer is ["C","E"]

Explanation

Choice A reason: Verapamil is not used for preterm labor; calcium channel blockers like nifedipine are preferred. Verapamil targets cardiovascular conditions, so this is incorrect for its therapeutic use.

Choice B reason: Verapamil is contraindicated in heart block, as it slows conduction. It is used for hypertension and dysrhythmias, not conduction blocks, so this is incorrect.

Choice C reason: Verapamil is a channel blocker used for essential hypertension, effectively reducing blood pressure by relaxing vessels. This is a standard use, making it a correct choice.

Choice D reason: Hypocalcemia is not treated with verapamil; it may worsen with calcium channel blockers. Cardiovascular indications are primary, so this is incorrect.

Choice E reason: Verapamil is used for cardiac dysrhythmias, such as supraventricular tachycardia, by slowing heart rate. This is a recognized indication, making it a correct choice.

A. 5 mL B. 6 mL C. 4 mL D. 2 mL

Correct Answer is D

Explanation

Choice A reason: To calculate volume, divide the ordered dose (40 mg) by the concentration (20 mg/mL): 40 ÷ 20 = 2 mL. Choice A (5 mL) delivers 100 mg (5 × 20), far exceeding the ordered dose, risking fluid and electrolyte imbalances, making it incorrect for safe administration.

Choice B reason: The correct volume is 40 mg ÷ 20 mg/mL = 2 mL. Choice B (6 mL) delivers 120 mg (6 × 20), significantly overdosing Lasix, which could cause severe dehydration, hypokalemia, or hypotension. This excessive dose is unsafe and incorrect for the prescribed administration.

Choice C reason: Calculating 40 mg ÷ 20 mg/mL yields 2 mL. Choice C (4 mL) delivers 80 mg (4 × 20), doubling the ordered dose. This could lead to excessive diuresis, electrolyte disturbances, or hypotension, making it an incorrect and potentially harmful choice for administration.

Choice D reason: Dividing the ordered dose (40 mg) by the concentration (20 mg/mL) gives 40 ÷ 20 = 2 mL. This volume accurately delivers the prescribed 40 mg of Lasix, ensuring effective diuresis for conditions like edema or heart failure while minimizing risks, making it the correct choice.
