Nursing Elites

1. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?

• A. 5 mL PO BID
• B. 5 mL PO daily
• C. 10 mL PO BID
• D. 10 mL PO daily

Correct answer: A

Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.

2. A nurse teaches a client who is recovering from a nephrectomy secondary to kidney trauma. Which statement should the nurse include in this client’s teaching?

• A. Since you only have one kidney, a salt and fluid restriction is required.
• B. Your therapy will include hemodialysis while you recover.
• C. Medication will be prescribed to control your high blood pressure.
• D. You need to avoid participating in contact sports like football.

Correct answer: D

Rationale: Clients with one kidney need to avoid contact sports because the kidneys are easily injured. The client will not be required to restrict salt and fluids, end up on dialysis, or have new hypertension because of the nephrectomy.

3. In a client with heart failure presenting bilateral +4 edema of the right ankle extending up to midcalf while sitting with legs dependent, what is the priority goal?

• A. Decrease venous congestion.
• B. Maintain normal respirations.
• C. Maintain body temperature.
• D. Prevent injury to lower extremities.

Correct answer: A

Rationale: The priority goal in this scenario is to decrease venous congestion. By elevating the legs above the heart level, venous return is improved, reducing congestion in the lower extremities. This intervention helps decrease swelling and prevents complications such as impaired tissue perfusion. Maintaining normal respirations and body temperature are important aspects of care but are secondary to addressing the immediate issue of venous congestion. Preventing injury to lower extremities is also essential but takes precedence after managing the venous congestion to prevent further complications.

4. A client has undergone renal angiography via the right femoral artery. The nurse determines that the client is experiencing a complication of the procedure upon noting:

• A. Urine output of 40 mL/hr
• B. Blood pressure of 118/76 mm Hg
• C. Respiratory rate of 18 breaths/min
• D. Pallor and coolness of the right leg

Correct answer: D

Rationale: Pallor and coolness of the right leg indicate a potential vascular complication following renal angiography, such as hemorrhage, thrombosis, or embolism. These signs suggest impaired circulation in the affected limb. Urine output, blood pressure, and respiratory rate are not typically associated with complications of renal angiography. Complications of this procedure mainly involve allergic reactions to the dye, dye-induced renal damage, and various vascular issues.

5. What is the priority intervention for a patient with a suspected myocardial infarction (MI)?

• A. Administering oxygen.
• B. Administering nitroglycerin.
• C. Administering aspirin.
• D. Administering morphine.

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with a suspected myocardial infarction to improve oxygenation. Oxygen helps ensure an adequate oxygen supply to the heart muscle, reducing the workload on the heart. Nitroglycerin and aspirin are important interventions in the treatment of MI; however, oxygen administration takes precedence to ensure adequate oxygenation. Morphine may be considered for pain relief, but it is not the initial priority in the treatment of a suspected MI.
