Nursing Elites

1. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?

• A. 4 mL
• B. 5 mL
• C. 6 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.

2. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

3. Phenytoin is an antiarrhythmic and anticonvulsant that has an unlabeled use for:

• A. Headaches
• B. Cold remedy
• C. Neuropathic pain
• D. Antianxiety

Correct answer: C

Rationale: Phenytoin, an antiarrhythmic and anticonvulsant medication, is also used off-label for treating neuropathic pain. While its primary indications are for managing heart rhythm disorders and seizures, it has shown efficacy in managing neuropathic pain, expanding its clinical utility. Choices A, B, and D are incorrect as phenytoin is not commonly used for headaches, cold remedies, or antianxiety purposes.

4. A client has a new prescription for Metronidazole. Which of the following instructions should be included in the discharge teaching?

• A. Avoid drinking alcohol while taking this medication.
• B. Take this medication on an empty stomach.
• C. Avoid dairy products while taking this medication.
• D. Take this medication with antacids.

Correct answer: A

Rationale: The correct instruction to include in the discharge teaching for a client prescribed Metronidazole is to avoid drinking alcohol while taking this medication. Drinking alcohol with Metronidazole can result in a disulfiram-like reaction, leading to symptoms such as nausea, vomiting, and flushing. Therefore, it is crucial for the client to abstain from alcohol consumption during the course of treatment with Metronidazole.

5. A client with chronic kidney disease has a new prescription for epoetin alfa. The nurse should instruct the client to increase dietary intake of which of the following substances?

• A. Iron
• B. Protein
• C. Potassium
• D. Sodium

Correct answer: A

Rationale: Patients with chronic kidney disease are often prescribed epoetin alfa to treat anemia. Epoetin alfa stimulates red blood cell production, increasing the body's demand for iron to support this process. Therefore, clients taking epoetin alfa should be advised to increase their dietary intake of iron-rich foods to meet the increased demand and prevent iron deficiency anemia. Choices B, C, and D are incorrect because while protein is essential for overall health, potassium and sodium intake may need to be restricted in clients with chronic kidney disease to manage electrolyte balance and blood pressure.
