Correct Answer: D

Rationale: The correct answer is to warm the fluids. Warming the dialysis fluids is crucial before initiating peritoneal dialysis to prevent abdominal discomfort and promote vasodilation, which helps in achieving good exchange in the peritoneum. Aspirating to check placement (Choice A) is not typically necessary before initiating peritoneal dialysis. Ensuring the client voids (Choice B) is not directly related to the procedure of peritoneal dialysis. Irrigating the catheter to maintain patency (Choice C) is usually done as part of routine care but is not specifically required prior to initiating peritoneal dialysis. Therefore, the most important action to take before starting peritoneal dialysis is to warm the fluids.

Correct Answer: D

Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.

Correct Answer: A

Rationale: The nurse should assess the client 2 hours post-lobectomy with 150cc drainage first because postoperative assessments are crucial during the immediate postoperative period. This client may be at higher risk for complications, such as bleeding or infection, requiring immediate attention. Clients in choices B, C, and D are relatively stable and can be assessed after the immediate postoperative client has been evaluated.

Correct Answer: B

Rationale: The correct answer is 'Alcohol and smoking.' Both alcohol consumption and smoking are well-known risk factors for various types of cancer. They have a synergistic effect, meaning their combined impact raises the risk significantly. Family history and environment (Choice A) may play a role in certain cancers, but alcohol and smoking are more directly linked to increased cancer risk. Proximity to an electric plant and water source (Choice D) is not typically associated with an increased risk of cancer compared to alcohol and smoking.

Correct Answer: B

Rationale: The most important information for the nurse to record after discontinuing a peripherally inserted central line (PICC) is the length and intactness of the central line catheter. This is crucial for assessing any potential complications or safety issues post-removal. Choices A, C, and D are not as critical as ensuring the condition of the central line catheter. While noting the client's tolerance of the procedure is relevant for their care assessment, evaluating the central line's integrity takes precedence in this scenario.
