Correct Answer: D

Rationale: The correct answer is D, infection. The client's symptoms of abdominal pain and feeling warm are indicative of a potential infection, which is a common complication of intraperitoneal therapy. Step-by-step rationale: 1. Abdominal pain can be a sign of peritonitis, an infection of the peritoneal cavity. 2. Feeling warm may indicate a fever, a common symptom of infection. 3. Prompt assessment and treatment of infection are crucial to prevent complications. Summary of other choices: A, allergic reaction - unlikely given the symptoms described; B, bowel obstruction - does not align with the symptoms provided; C, catheter lumen occlusion - not typically associated with abdominal pain and feeling warm.

Correct Answer: A

Rationale: The correct answer is A: Assess the airway. The nurse should prioritize airway assessment as the client's ABGs indicate respiratory acidosis (low pH, high PaCO2). This suggests potential airway obstruction or inadequate ventilation. Ensuring a patent airway is crucial for adequate oxygenation. Administering bronchodilators (B) or mucolytics (D) may help with airway clearance but should come after ensuring a clear airway. Providing oxygen (C) is important, but addressing the underlying respiratory acidosis by first assessing the airway is the priority in this situation to prevent further deterioration.

Correct Answer: A

Rationale: The correct action for the nurse to take first is to assess the client's respiratory rate, rhythm, and depth (Choice A). Diminished handgrip strength in a client with hypokalemia could indicate potential respiratory muscle weakness, which can lead to respiratory distress or failure. By assessing the client's respiratory status, the nurse can determine if immediate intervention is needed to support breathing. Choice B is incorrect because measuring the client's pulse and blood pressure may not address the underlying issue of respiratory muscle weakness. Choice C is incorrect as it delays potential life-saving interventions by simply documenting findings. Choice D is incorrect as calling the healthcare provider should come after addressing the client's immediate respiratory needs.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Choice C is correct because it emphasizes the importance of cleaning connections before accessing the device to prevent infection. 2. Sterile technique during insertion cannot guarantee no risk of infection (Choice B). 3. Wearing a sling is unnecessary for a central vascular access device (Choice A). 4. The statement about not being able to take a bath is not accurate and is not a common restriction (Choice D).

Correct Answer: B

Rationale: The correct answer is B because limiting fluids can lead to dehydration, which can cause confusion and dry mucous membranes. Adjusting the timing of fluids can help maintain hydration without causing frequent nighttime bathroom trips. Choice A is incorrect because hospital readmission is not necessary at this point. Choice C is incorrect as it normalizes confusion post-surgery and dangerous practice of avoiding urination at night. Choice D is incorrect because urine accumulation in the bladder does not directly cause confusion; dehydration is the primary concern.
