Correct Answer: B

Rationale: Irritability is an early indicator that suctioning is necessary for a client with a tracheostomy. Irritability can signal discomfort or difficulty breathing, which may be due to the need for suctioning to clear the airway. Decreased respiratory rate, bradycardia, and decreased oxygen saturation are not typically early indicators that suctioning is needed in a client with a tracheostomy. These symptoms may occur later if the airway is not cleared promptly.

Correct Answer: A

Rationale: The correct way to assess for pitting edema is to press over a bony area, typically the tibia, for 5 seconds and then release. This allows for the identification of pitting edema, characterized by an indentation that persists for a few seconds. Choice B is incorrect as pitting edema assessment does not involve checking for discoloration. Choice C is incorrect as the presence of a rash is not indicative of pitting edema. Choice D is incorrect as rebound tenderness is a different assessment used for abdominal conditions, not for pitting edema.

Correct Answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium is often caused by underlying issues such as infections, medication side effects, or metabolic imbalances. Addressing these root causes can help resolve delirium more effectively. Administering antipsychotic or sedative medications should not be the initial approach as they can worsen delirium in some cases. Providing a low-stimulation environment is beneficial but not the priority when reversible causes need to be addressed first.

Correct Answer: B

Rationale: To administer 10 mg of metoclopramide, the nurse should administer 2 mL (10 mg / 5 mg per mL). Therefore, the correct answer is 2 mL. Choice A (1 mL) is incorrect because it would only deliver 5 mg of metoclopramide, which is half the required dose. Choice C (3 mL) and D (4 mL) are incorrect as they would provide more than the required dose of 10 mg.

Correct Answer: D

Rationale: The correct intervention for the nurse to include in the plan of care for a client undergoing total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. Changing the tubing at regular intervals helps reduce the risk of infection associated with central venous catheters. Monitoring electrolyte levels daily (Choice A) is important but not specific to TPN. Weighing the client daily (Choice B) is important for monitoring fluid status but not directly related to TPN. Monitoring blood glucose levels every 6 hours (Choice C) is essential for clients receiving TPN, but changing the tubing is a more critical intervention to prevent infections.
