1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. A client who is nonambulatory notifies the nurse that his trash can is on fire. After the nurse confirms the fire, which of the following actions should the nurse take next?

• A. Activate the emergency fire alarm
• B. Extinguish the fire
• C. Evacuate the client
• D. Confine the fire

Correct answer: C

Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.

3. What advice should the client be given if they are feeling dizzy upon standing after taking a diuretic for hypertension?

• A. Avoid standing up too quickly.
• B. Increase fluid intake to stay hydrated.
• C. Eat more salt to help retain fluids.
• D. Wear compression stockings during the day.

Correct answer: A

Rationale: The correct advice for a client feeling dizzy upon standing after taking a diuretic for hypertension is to avoid standing up too quickly. Diuretics can lead to orthostatic hypotension, causing dizziness upon sudden position changes. Increasing fluid intake can exacerbate the issue by further lowering blood pressure. Eating more salt might counteract the diuretic's effects but is not the primary intervention for orthostatic hypotension. Compression stockings are more relevant for venous insufficiency than for orthostatic hypotension.

4. The nurse is caring for a client diagnosed with hypothyroidism. Which finding should the nurse expect to observe?

• A. Weight gain
• B. Heat intolerance
• C. Increased appetite
• D. Frequent diarrhea

Correct answer: A

Rationale: The correct answer is weight gain. In hypothyroidism, there is a decrease in metabolic rate, which can lead to weight gain. Heat intolerance (choice B) is more commonly associated with hyperthyroidism. Increased appetite (choice C) and frequent diarrhea (choice D) are not typical findings in hypothyroidism. Therefore, choices B, C, and D are incorrect.

5. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.
