N-acetyl-para-aminophenol is an example of which type of drug name?

Choice A reason: Taking antihistamines only with symptoms may reduce side effects but provides inconsistent relief, as histamine levels fluctuate. Daily use during allergy seasons prevents symptom onset, offering better control, especially for second-generation antihistamines with longer action, making this choice less effective.

Choice B reason: First-generation antihistamines (e.g., diphenhydramine) are sedating and have more side effects than second-generation (e.g., loratadine), which are equally effective for allergies but less sedating. Claiming first-generation are more effective is incorrect, as second-generation are preferred, making this choice inaccurate.

Choice C reason: Anticholinergic effects (e.g., dry mouth) are more common with first-generation antihistamines (e.g., diphenhydramine) due to non-selective receptor binding. Second-generation antihistamines (e.g., cetirizine) are more selective for H1 receptors, reducing these effects, making this choice incorrect and opposite to pharmacological profiles.

Choice D reason: Daily oral antihistamines, especially second-generation (e.g., loratadine), during allergy seasons maintain steady histamine receptor blockade, preventing symptoms like sneezing and itching. This maximizes efficacy and improves quality of life, aligning with guidelines for seasonal allergies, making this the correct nurse response.

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.
