The nurse reviews a primary health care provider’s prescriptions and notes that a topical nitrate is prescribed. The nurse notes that acetaminophen is prescribed to be administered before the nitrate.
The nurse implements the prescription with which understanding about why acetaminophen is prescribed?

Choice A rationale

Administering diphenhydramine with food does not specifically address the adverse effect of dry mouth. While taking the medication with food can help reduce gastrointestinal side effects, it does not alleviate dry mouth.

Choice B rationale

Chewing on sugarless gum or sucking on hard candies can help stimulate saliva production and alleviate dry mouth. This is an effective and simple measure to manage the adverse effect of dry mouth associated with diphenhydramine.

Choice C rationale

Placing a humidifier at the bedside can help maintain moisture in the air, but it is not the most effective measure for managing dry mouth. Chewing gum or sucking on candies directly stimulates saliva production, providing more immediate relief.

Choice D rationale

Discontinuing the medication and notifying the provider is not necessary for managing dry mouth. Dry mouth is a common and manageable side effect of diphenhydramine. Simple measures like chewing gum or sucking on candies are usually sufficient to alleviate this symptom

Choice A rationale

Fever usually accompanies myocardial infarction. This statement is incorrect. While fever can occur with myocardial infarction, it is not a common or primary symptom. Acetaminophen is not prescribed for this reason.

Choice B rationale

Acetaminophen does not interfere with platelet action as acetylsalicylic acid (aspirin) does. This statement is correct but not the reason for prescribing acetaminophen before nitrates. Acetaminophen is chosen for its analgesic properties without affecting platelet function.

Choice C rationale

Headache is a common side effect of nitrates. This statement is correct. Nitrates can cause vasodilation, leading to headaches. Acetaminophen is prescribed to manage this common side effect.

Choice D rationale

Acetaminophen potentiates the therapeutic effect of nitrates. This statement is incorrect. Acetaminophen does not enhance the therapeutic effects of nitrates; it is used to manage side effects like headaches.
