Nursing Elites

1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.

2. A 60-year-old male with type 2 diabetes mellitus tells the nurse that he is going to join a gym and start working out. Which information is most important for the nurse to obtain?

• A. Recent serum cholesterol levels
• B. Presence of calf pain during exercise
• C. Average weight gain or loss in the last year
• D. Exercise tolerance test with EKG results

Correct answer: B

Rationale: The most important information for the nurse to obtain in this scenario is the presence of calf pain during exercise. Calf pain during exercise could indicate peripheral vascular issues, such as peripheral artery disease, which is crucial to address before starting an exercise program. High cholesterol levels (choice A) may be important but are not as immediately relevant as assessing for peripheral vascular issues. Average weight gain or loss (choice C) may provide some insight into the patient's overall health status but is not as critical as assessing for potential vascular complications. An exercise tolerance test with EKG results (choice D) may be valuable in assessing cardiovascular fitness but is not as crucial as evaluating for peripheral vascular issues given the patient's symptoms.

3. The nurse is preparing to send a client to the cardiac catheterization lab for an angioplasty. Which client report is most important for the nurse to explore further prior to the start of the procedure?

• A. Verbalizes a fear of being in a confined space.
• B. Drank a glass of water in the past 2 hours.
• C. Reports left chest wall pain prior to admission.
• D. Experiences facial swelling after eating crab

Correct answer: C

Rationale: The correct answer is C. Left chest wall pain could indicate ongoing cardiac issues or instability, which needs to be assessed before proceeding with the procedure. This pain could be related to the heart and may suggest a potential risk during the angioplasty. Options A, B, and D do not directly relate to cardiac complications during the procedure, making them less urgent for immediate assessment. Fear of confined spaces, drinking water, and facial swelling after eating crab are not immediate risks to the client's safety in the context of a cardiac catheterization procedure.

4. Three hours following a right carotid endarterectomy, the nurse notes a moderate amount of bloody drainage on the client’s dressing. Which additional assessment finding warrants immediate intervention by the nurse?

• A. Sore throat when swallowing
• B. Tongue deviation to the left
• C. Palpable temporal pulses
• D. Temperature of 99.2°F (37.3°C)

Correct answer: B

Rationale: Tongue deviation to the left is the correct answer. It could indicate a complication such as nerve injury or hematoma, which requires immediate attention. A sore throat when swallowing may be expected postoperatively but does not indicate an immediate complication. Palpable temporal pulses are a normal finding and do not require immediate intervention. A temperature of 99.2°F (37.3°C) is slightly elevated but does not suggest a critical issue related to the surgery.

5. To prevent aspiration in a client on mechanical ventilation receiving continuous enteral feedings through a nasogastric tube, which intervention is most important for the nurse to implement?

• A. Verify the feeding tube position with a daily chest x-ray
• B. Maintain head of bed elevated while enteral feeding is infusing
• C. Check feeding tube placement with air bolus prior to use
• D. Aspirate stomach contents every 4 hours to assess residuals

Correct answer: B

Rationale: The most important intervention to prevent aspiration in a client receiving continuous enteral feedings through a nasogastric tube while on mechanical ventilation is to maintain the head of the bed elevated while the feeding is infusing. This position helps reduce the risk of regurgitation and aspiration. Options A, C, and D are not as crucial as maintaining proper positioning to prevent aspiration. Verifying tube position with a daily chest x-ray is important but not the most crucial. Checking tube placement with an air bolus and aspirating stomach contents are important procedures but do not directly address the prevention of aspiration during enteral feedings.
