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.

Correct Answer: B

Rationale: The correct response is to provide oxygen through a tube in the client's nose. Oxygen therapy can offer comfort and support breathing without being considered resuscitative. Therefore, this intervention aligns with the client's wish to decline resuscitation. Option A is not directly related to addressing the client's immediate breathing difficulty. Option C does not acknowledge the client's living will decision. Option D involves a more invasive procedure that may go against the client's wishes to decline resuscitation.

Correct Answer: A

Rationale: Encouraging the client to use the incentive spirometer 4-5 times per hour is the correct approach post-gallbladder surgery under general anesthesia. This frequency helps prevent respiratory complications, such as atelectasis, by promoting lung expansion. Choices B, C, and D suggest either too few or too many sessions per hour, which may not be optimal for the client's respiratory recovery needs. It is important to strike a balance between ensuring adequate lung expansion and not overexerting the client, which is why 4-5 times per hour is the recommended frequency.

Correct Answer: D

Rationale: The correct action is to change the TPN bag every 24 hours to reduce the risk of infection. Changing the TPN tubing every 72 hours (Choice B) may increase the risk of contamination. Monitoring the client's blood glucose level every 4 hours (Choice A) is important but not specific to TPN administration. Weighing the client daily (Choice C) is essential for monitoring fluid status but is not directly related to TPN administration.

Correct Answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.
