The nurse is caring for an immunosuppressed pediatric client who reports soreness in his mouth and refuses to eat. Inspection of his mouth reveals a white, milky plaque that does not come off with rubbing. The nurse should anticipate which drug to be administered to this client?
nystatin (Mycostatin)
amoxicillin (Amoxil)
metronidazole (Flagyl)
acyclovir (Zovirax)
The Correct Answer is A
A. Nystatin is an antifungal medication used to treat oral candidiasis (thrush), which is consistent with the client's symptoms of soreness in the mouth and the presence of a white, milky plaque that does not rub off.
B. Amoxicillin is an antibiotic that treats bacterial infections but would not be effective against fungal infections like oral thrush.
C. Metronidazole is an antibiotic and antiprotozoal medication, which is not appropriate for treating oral candidiasis.
D. Acyclovir is an antiviral medication used to treat infections caused by certain viruses, such as herpes, and is not effective for fungal infections like thrush.

Correct Answer is B
Explanation
A. Daily weight monitoring is not specifically indicated for doxazosin, and significant weight loss is typically not a primary concern with this medication.
B. Doxazosin can cause first-dose hypotension, leading to dizziness; thus, the client should be advised to lie down after the initial dose to minimize this risk.
C. Increasing potassium intake is not necessary with doxazosin; there are no direct interactions that would warrant dietary changes regarding potassium.
D. Impaired taste is not a commonly reported side effect of doxazosin; this statement is misleading and not relevant to the medication's profile.
Correct Answer is ["C","E","F"]
Explanation
A. Rebound hypotension is more commonly associated with abrupt withdrawal of beta-blockers rather than a direct side effect, so it is not typically included as a side effect to expect while on the medication.
B. Vomiting is not a common side effect associated with propranolol; the nurse would not educate the client on this.
C. Bradycardia is a known side effect of propranolol, as it is a beta-blocker that decreases heart rate, so clients should be educated about monitoring their heart rate.
D. Tremors can be related to withdrawal from beta-agonists rather than propranolol, which may alleviate tremors in some individuals; thus, it's not a common side effect of the medication.
E. Propranolol can mask the symptoms of hypoglycemia (e.g., tachycardia), making it important for clients with diabetes to be aware of this potential effect.
F. Bronchoconstriction can occur in clients with reactive airway diseases, as propranolol non-selectively blocks beta receptors, so clients should be educated about this risk, especially if they have asthma or other pulmonary conditions.
