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. A client prescribed Isosorbide Mononitrate for chronic stable Angina develops reflex tachycardia. Which of the following medications should the nurse expect to administer?

• A. Furosemide
• B. Captopril
• C. Ranolazine
• D. Metoprolol

Correct answer: D

Rationale: Metoprolol, a beta-adrenergic blocker, is commonly used to treat hypertension and stable angina pectoris. It is often prescribed to decrease heart rate in clients experiencing tachycardia, including those with reflex tachycardia induced by medications like Isosorbide Mononitrate. Furosemide (Choice A) is a diuretic and is not indicated for reflex tachycardia. Captopril (Choice B) is an ACE inhibitor used for hypertension and heart failure, not tachycardia. Ranolazine (Choice C) is used in chronic angina but does not address tachycardia.

3. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

4. The client with angina is being discharged to home. The nurse is instructing the client on dietary changes. What should be included in this teaching?

• A. Decrease salt and fat intake and limit alcohol intake.
• B. There are no dietary restrictions for a person diagnosed with angina.
• C. Limit smoking and increase protein and sugar intake.
• D. Increase fruits, vegetables, and foods high in cholesterol.

Correct answer: A

Rationale: The correct answer is to decrease salt and fat intake and limit alcohol intake. These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.

5. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?

• A. These medications work by inhibiting enzymes to prevent HIV replication.
• B. These medications work by preventing protein synthesis within the HIV cell.
• C. These medications work by weakening the cell wall of the HIV virus.
• D. These medications work by blocking HIV entry into cells.

Correct answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.
