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. The nurse is providing discharge teaching to a client who has undergone abdominal surgery. What instruction should the nurse include?
- A. Avoid heavy lifting for at least 6 weeks
- B. Limit fluid intake to reduce the risk of infection
- C. Resume normal activities as soon as possible
- D. Avoid driving for at least 2 weeks
Correct answer: A
Rationale: The correct answer is A: 'Avoid heavy lifting for at least 6 weeks.' After abdominal surgery, it is essential to avoid heavy lifting to prevent complications such as incisional hernias and support proper healing. Choice B, 'Limit fluid intake to reduce the risk of infection,' is incorrect because adequate fluid intake is necessary for wound healing and preventing dehydration. Choice C, 'Resume normal activities as soon as possible,' is incorrect as it may increase the risk of complications and delay healing. Choice D, 'Avoid driving for at least 2 weeks,' is incorrect as the restriction on driving may vary depending on the type of surgery and individual recovery.
3. 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.
4. The nurse receives change of shift report on a group of clients for the upcoming shift. A client with which condition requires the most immediate attention by the nurse?
- A. Gunshot wound three hours ago with dark drainage of 2 cm on the dressing
- B. Mastectomy 2 days ago with 50 ml bloody drainage in the Jackson-Pratt drain
- C. Collapsed lung after a fall 8 hours ago with 100 ml blood in the chest tube collection container
- D. Abdominal-perineal resection 2 days ago with no drainage on dressing and fever and chills
Correct answer: C
Rationale: A collapsed lung with significant blood accumulation requires immediate attention to prevent respiratory compromise. Option A may also require attention, but the immediate threat to airway and breathing in option C takes precedence over the others. Option B has expected drainage after a mastectomy, and option D's fever and chills, while concerning, do not pose an immediate life-threatening risk as in option C.
5. What assessment data should lead the nurse to suspect that a client has progressed from HIV infection to AIDS?
- A. Enlarged and tender cervical lymph nodes
- B. Presence of low-grade fever and sore throat
- C. Recent history of recurrent pneumonia
- D. CD4 blood cell count of 300
Correct answer: C
Rationale: The correct answer is C: 'Recent history of recurrent pneumonia.' Recurrent pneumonia is a hallmark indicator of progression to AIDS in clients with HIV infection. It signifies advanced immunosuppression when the body is unable to fight off infections effectively. Enlarged and tender cervical lymph nodes (Choice A) are more indicative of local infections or inflammation rather than AIDS progression. The presence of a low-grade fever and sore throat (Choice B) may be common in various infections and are not specific to AIDS progression. While a CD4 blood cell count of 300 (Choice D) is below the normal range and indicates immunosuppression, it alone may not be sufficient to suspect progression to AIDS without other supporting indicators like opportunistic infections such as recurrent pneumonia.
