Correct Answer: D

Rationale: The correct answer is D: Beneficence. Beneficence involves actions intended to benefit the client, such as providing pain relief. In this scenario, the nurse is demonstrating beneficence by offering pain medication to alleviate the client's discomfort and promote their well-being. Fidelity (A) relates to being faithful to agreements and commitments, autonomy (B) refers to respecting a client's right to make decisions about their care, and justice (C) involves fairness and equal treatment. While these ethical principles are important in healthcare, the situation described primarily exemplifies the principle of beneficence.

Correct Answer: A

Rationale: The correct instruction is to use tracheostomy covers when outdoors. Tracheostomy covers serve to protect the airway from environmental contaminants, reducing the risk of infection. Choice B is incorrect because hydrogen peroxide can be irritating to the skin and is not recommended for cleaning the tracheostomy site. Choice C is incorrect as tracheostomy tubes should not be routinely changed weekly unless there is a specific medical indication. Changing it without a need can introduce infection or damage the stoma. Choice D is incorrect as applying ointment around the tracheostomy site can lead to occlusion of the stoma and interfere with breathing.

Correct Answer: A

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client has a new prescription for wrist restraints is to pad the client's wrists before applying the restraints. This is important to prevent skin breakdown and injury. Tying the restraints to the side rails of the bed (Choice B) is unsafe and can lead to potential harm for the client. Similarly, securing the restraints to the bed frame (Choice C) is not appropriate as it can restrict the client's movement and cause discomfort. Using a quick-release knot to tie the restraints (Choice D) is also incorrect as it may compromise the effectiveness of the restraints in ensuring client safety.

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.
