A nurse is administering a monoamine oxidase inhibitor (MAOIS) to a client. Which of the following nursing actions is most important to ensure safe medication administration?
Monitoring the client's blood pressure regularly.
Educating the client on the importance of avoiding foods high in tyramine.
Administering the medication with a full glass of milk.
Assessing the client's fasting blood sugar levels before administration.
The Correct Answer is B
A. Monitoring the client's blood pressure regularly: Blood pressure monitoring is important because MAOIs can precipitate hypertensive crises. However, prevention is more critical than detection after the fact. Relying solely on monitoring does not eliminate the underlying trigger for severe hypertension associated with dietary interactions.
B. Educating the client on the importance of avoiding foods high in tyramine: MAOIs inhibit monoamine oxidase, the enzyme responsible for breaking down tyramine in the gastrointestinal tract. Accumulation of tyramine leads to excessive norepinephrine release, causing severe vasoconstriction and potentially life-threatening hypertensive crisis. Avoiding aged cheeses, cured meats, fermented products, and certain alcoholic beverages is essential for safety.
C. Administering the medication with a full glass of milk: There is no pharmacologic requirement to administer MAOIs with milk. Food does not significantly alter the drug’s mechanism of action related to monoamine oxidase inhibition.
D. Assessing the client's fasting blood sugar levels before administration: MAOIs are primarily used for treatment-resistant depression and certain anxiety disorders. They do not directly alter glucose metabolism in a predictable manner that would require routine fasting glucose assessment prior to administration.

Correct Answer is ["56.8"]
Explanation
Calculation:
Identify the client’s weight in pounds
Weight: 125 lbs
Convert pounds to kilograms
1 kg = 2.2 lbs
Weight in kg = 125 ÷ 2.2
= 56.818 kg
Round to one decimal place
= 56.8 kg
Correct Answer is C
Explanation
A. "I'll report any new confusion, dizziness, or unsteady gait that occurs after starting a new medication.": Older adults are more susceptible to central nervous system effects due to altered pharmacokinetics and increased blood-brain barrier permeability. Symptoms such as confusion, dizziness, or gait instability increase fall risk and may indicate drug accumulation or sensitivity.
B. “I’ll avoid abruptly stopping any medication, even if I start to feel better.": Abrupt discontinuation of certain medications, such as beta-blockers, benzodiazepines, or antidepressants, can result in rebound effects or withdrawal symptoms. Gradual tapering is often required to maintain physiologic stability.
C. "Because my metabolism has slowed down, it might take longer for medications to start working, so I can take another dose if I don't feel better.": Age-related reductions in hepatic metabolism and renal clearance increase the risk of drug accumulation and toxicity. Taking an extra dose without provider guidance can lead to supratherapeutic levels and adverse effects.
D. "Since my kidneys don't clear drugs as efficiently, I should avoid taking over-the-counter medications unless approved by my provider.": Renal function often declines with age, reducing drug clearance and increasing susceptibility to toxicity. Many over-the-counter medications, including NSAIDs and antihistamines, can impair renal function or interact with prescribed therapies.
