What is the major reason that monoamine oxidase inhibitors (MAOIs) are rarely used in clinical practice today?

They are under a scheduled drug classification.

They are ineffective in treating depression or anxiety disorders.

They can cause gastrointestinal (GI) bleeding and esophageal varices.

They may cause dangerous interactions with some foods and drugs.

Answer and Explanation

The Correct Answer is D

A. While MAOIs may have some regulatory considerations, they are not classified under a scheduled drug classification like controlled substances.

B. MAOIs are effective in treating depression and anxiety disorders, which is not the reason for their limited use.

C. Although MAOIs can have some side effects, they are more notably associated with dietary and drug interactions rather than causing GI bleeding or esophageal varices.

D. MAOIs can cause dangerous interactions with foods that contain tyramine (like aged cheeses and fermented products) and certain medications, leading to hypertensive crises, making their use cautious and limiting in clinical practice.

Correct Answer is B

Explanation

A. Using combination therapy may be beneficial in some cases but is not the first step in ensuring the most appropriate drug is chosen for a specific pathogen.

B. Obtaining sensitivity testing is essential to determine the specific antibiotic to which the pathogen is susceptible, ensuring effective treatment.

C. Checking client allergies is important to prevent adverse reactions but does not directly address whether the chosen drug is appropriate for the pathogen.

D. Evaluating the bactericidal effects is part of assessing the treatment's effectiveness, but it should follow sensitivity testing to determine the correct medication.

A. "You will lose less potassium with spironolactone than with furosemide." B. "You will have greater potassium losses with spironolactone than with furosemide." C. "You will have greater water losses with spironolactone than with furosemide." D. "You will have greater sodium losses with spironolactone than with furosemide."

Correct Answer is A

Explanation

A. Spironolactone is a potassium-sparing diuretic, meaning it helps retain potassium while promoting sodium and water excretion. This makes it advantageous for clients who may be at risk for hypokalemia with furosemide, which can lead to significant potassium loss.

B. This statement is incorrect; spironolactone causes less potassium loss compared to furosemide, making it a better option for those needing to maintain potassium levels.

C. This statement is misleading; spironolactone does promote diuresis but does not cause greater water losses than furosemide.

D. This is incorrect; while spironolactone does promote sodium excretion, it does not do so to a greater extent than furosemide, which is a more potent diuretic.
