A nurse is caring for a child who has recurrent otitis media. The child weighs 14.9 kg (33 lb). A prescription is written for amoxicillin 40 mg/kg PO to be given in two divided doses per day. The pharmacy provides the nurse with amoxicillin 250 mg/5 mL. How many mL of the medication should the nurse plan to administer for each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. "I can discontinue this medication after one negative sputum culture." Treatment for tuberculosis requires a long-term regimen lasting at least 6 months, even if the sputum culture becomes negative. Discontinuing rifampin too early increases the risk of drug resistance and treatment failure. The client must continue therapy as prescribed and complete the full course.

B. "I should take this medication on an empty stomach." Rifampin should be taken on an empty stomach (1 hour before or 2 hours after meals) to improve absorption and effectiveness. Food can reduce the bioavailability of the drug, making it less effective in treating tuberculosis. If gastrointestinal discomfort occurs, the client should consult their provider before making adjustments.

C. "I should expect to have ringing in my ears." Tinnitus (ringing in the ears) is not a common side effect of rifampin. Ototoxicity is more commonly associated with aminoglycosides (e.g., streptomycin) or vancomycin. Rifampin’s notable side effects include hepatotoxicity, red-orange discoloration of body fluids, and gastrointestinal disturbances.

D. "I can expect to have joint pain." While rifampin can cause mild flu-like symptoms, including fatigue and muscle aches, persistent joint pain is not a typical side effect. If joint pain occurs, it may be related to another condition, such as drug-induced hepatotoxicity or an adverse reaction to other tuberculosis medications (e.g., pyrazinamide, which can cause gout-like symptoms).

A. Oatmeal. Oatmeal is a healthy carbohydrate and fiber source, but it is not a significant source of potassium, which is essential for clients taking furosemide. While beneficial for overall health, oatmeal will not help counteract potassium loss caused by diuretic therapy.

B. Baked potatoes. Baked potatoes are rich in potassium, which is frequently lost due to furosemide’s potassium-wasting effects. Furosemide is a loop diuretic that increases urine output and depletes electrolytes, particularly potassium, which can lead to hypokalemia (low potassium levels). To help maintain electrolyte balance, clients should consume potassium-rich foods like potatoes, bananas, oranges, and spinach.

C. Brown rice. Brown rice is a good source of fiber and complex carbohydrates, but it contains only small amounts of potassium. While it provides sustained energy, it does not significantly contribute to potassium replacement, making it less beneficial for clients on furosemide.

D. Eggs. Eggs are high in protein and essential nutrients but are not a significant source of potassium. While eggs are beneficial for overall health, they do not help replenish potassium lost due to diuretic therapy.
