The nurse is reviewing a client's daily medications taken at home. Which of the following medications has a risk of dependency if used daily?
bisacodyl (Dulcolax)
psyllium (Metamucil)
polyethylene glycol (MiraLAX)
docusate sodium (Colace)
The Correct Answer is A
A. Bisacodyl is a stimulant laxative that can lead to dependency if used daily, as the body may become reliant on the medication for bowel movements. Chronic use can also result in electrolyte imbalances and diminished bowel function.
B. Psyllium is a bulk-forming laxative that works by increasing the bulk of stool and does not typically lead to dependency.
C. Polyethylene glycol is an osmotic laxative that can be used daily without a significant risk of dependency, as it draws water into the bowel to facilitate stool passage.
D. Docusate sodium is a stool softener that aids in preventing constipation but does not carry a risk of dependency when used regularly.

Correct Answer is B
Explanation
A. Cherries do not contain tyramine, which is the compound of concern for clients on MAOIs, so they can be included in the diet.
B. Cheddar cheese is high in tyramine, which can lead to hypertensive crises when consumed by clients taking MAOIs. Therefore, it should be eliminated from the diet.
C. Chicken is generally safe for clients on MAOIs as it does not contain significant amounts of tyramine.
D. Fresh fish is also safe to consume while on MAOIs as long as it is fresh and not aged, fermented, or spoiled, which could contain higher tyramine levels.
Correct Answer is C
Explanation
A. PT/INR is not the appropriate measure for heparin therapy, as heparin is monitored using activated partial thromboplastin time (aPTT). This response could mislead the client regarding treatment expectations.
B. While it may take time to reach therapeutic levels, this statement doesn't clarify that heparin is not a clot-dissolving agent.
C. Heparin prevents the extension of existing clots and the formation of new clots but does not actively dissolve clots already present.
D. This statement incorrectly suggests that immediate effects are seen, which is not the case as heparin's action involves prevention rather than dissolution.
