The nurse should monitor for which potential clinical manifestation after administering furosemide (Lasix)?

Decreased blood pressure

Decreased temperature

Decreased pulse

Decreased respiratory rate

Answer and Explanation

The Correct Answer is A

Choice A reason: Furosemide, a loop diuretic, reduces blood volume, often lowering blood pressure. Monitoring for hypotension is critical to prevent dizziness or shock, making this the correct manifestation to observe.

Choice B reason: Decreased temperature is not a common effect of furosemide, which primarily affects fluid balance. Blood pressure changes are more relevant, so this is incorrect.

Choice C reason: Furosemide may increase heart rate due to volume loss, not decrease pulse. Hypotension is a primary concern, making this incorrect for the expected manifestation.

Choice D reason: Decreased respiratory rate is unrelated to furosemide, which may improve breathing in heart failure but not slow respiration. Blood pressure is key, so this is incorrect.

Correct Answer is A

Explanation

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.

A. Agonist B. Antagonist C. Potent D. Selective

Correct Answer is B

Explanation

Choice A reason: Agonists activate receptors, mimicking endogenous ligands, not preventing activation. The drug blocks receptors, so this is incorrect for the described action.

Choice B reason: Antagonists prevent receptor activation by blocking ligand binding, inhibiting effects. This matches the drug’s action, making it the correct term.

Choice C reason: Potent describes a drug’s strength, not its mechanism of preventing receptor activation. Antagonist defines the action, so this is incorrect.

Choice D reason: Selective refers to targeting specific receptors, not preventing activation. Antagonist describes the functional role, so this is incorrect.
