In which of the following conditions should decongestants be used with caution?

Choice A rationale
While obtaining a blood pressure is an important part of overall patient assessment, it is not the priority action before administering antibiotics for a urinary tract infection.

Choice B rationale
Obtaining a urine specimen for culture and sensitivity is the priority action before administering antibiotics for a urinary tract infection. This allows for identification of the specific bacteria causing the infection and determination of the most effective antibiotic for treatment.
Choice C rationale
Obtaining a PTT (partial thromboplastin time) is not typically necessary before administering antibiotics for a urinary tract infection.
Choice D rationale
Obtaining a platelet count is not typically necessary before administering antibiotics for a urinary tract infection.

The correct answer is = D. Foods that contain tyramine and caffeine

Here's the rationale for each choice:

• Choice A rationale: Large amounts of water are generally safe for people taking MAOIs and can even help prevent dehydration, which can worsen some side effects.
• Choice B rationale: A diet high in salt may raise blood pressure, but it's not a specific concern related to the interaction of MAOIs with food.
• Choice C rationale: A diet high in fat doesn't directly interact with MAOIs. While a healthy diet is recommended overall, fat content isn't a primary concern.
• Choice D rationale: Foods containing tyramine and caffeine can interact with MAOIs, potentially leading to a dangerous increase in blood pressure. MAOIs inhibit the breakdown of these substances, so avoiding them is crucial.

Therefore, clients taking MAOIs should be instructed to avoid foods high in tyramine and caffeine.
