Correct Answer: A

Rationale: The correct answer is to give 4.8 ml q6 hr. To calculate the dose, you divide the prescribed dose of 120 mg by the concentration of Survanta, which is 100 mg per 4 ml. This results in 4.8 ml per dose, as 120 mg · 100 mg/4 ml = 4.8 ml. Option B suggesting to notify the healthcare provider that the dose is too high is incorrect because the calculated dose of 4.8 ml is based on the recommended dose of 100 mg/kg birth weight. Option C suggesting to notify the healthcare provider that the dose is too low is incorrect as the calculated dose is based on the correct dosage calculation. Option D suggesting to give 1.2 ml q6 hr is incorrect because it doesn't align with the correct calculation.

Correct Answer: A

Rationale: The correct action for the nurse to take before leaving the room is to ensure that the knot can be quickly released. Using a half bow knot to attach the client's wrist restraints allows for quick release in case of an emergency. This is crucial for ensuring the safety of the client and complying with restraint policies. Tying the knot with a double turn or square knot (Choice B) would make it difficult to release quickly when needed. Moving the ties so the restraints are secured to the side rails (Choice C) does not address the immediate need for a quick release. Ensuring that the restraints are snug against the client's wrist (Choice D) may not be appropriate if the restraints need to be quickly removed for the client's safety.

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.

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.

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.
