Correct Answer: B

Rationale: When a patient is already receiving glucocorticoids for rheumatoid arthritis and complains of a headache, it is essential to consider the potential interactions and side effects of additional medications. Aspirin and NSAIDs like ibuprofen and naproxen sodium can increase the risk of gastrointestinal irritation and ulceration when used concurrently with glucocorticoids. Acetaminophen is a safer choice in this scenario for managing the patient's headache without exacerbating the gastrointestinal issues associated with the use of glucocorticoids.

Correct Answer: B

Rationale: Postural hypotension is common early in treatment, so the patient should be instructed to change positions slowly. Administration with meals should be avoided, if possible, because food delays the absorption of the levodopa component. If the patient is experiencing side effects of nausea and vomiting, administration with food may be considered. The levodopa component may darken urine. Carbidopa has no adverse effects of its own.

Correct Answer: A

Rationale: McBurney's point is located in the right lower quadrant of the abdomen, specifically between the umbilicus and the anterior iliac crest. This point is significant in diagnosing appendicitis, as tenderness at McBurney's point is a classic sign of appendicitis and indicates inflammation near the appendix.

Correct Answer: B

Rationale: If diuresis has not occurred with corticosteroids in nephrotic syndrome, a diuretic like Furosemide (Lasix) is the appropriate choice to promote diuresis. Furosemide works by increasing urine production and reducing fluid retention. While Ibuprofen is an anti-inflammatory agent, it does not directly induce diuresis. Ciprofloxacin is an antibiotic and is not indicated for promoting diuresis in this scenario. Cyclophosphamide is an immunosuppressant, not an antisuppressant, and is not typically used to induce diuresis in nephrotic syndrome.

Correct Answer: C

Rationale: MOM is a rapid-acting antacid with a prominent adverse effect of diarrhea. To compensate, it usually is administered in combo with aluminum hydroxide which promotes constipation. A reduction in dose might be necessary if the diarrhea is severe, but this is not a priority action. Increasing dietary fiber and keeping a stool count are appropriate actions to implement after adding an antacid to counteract the diarrhea effect.
