Correct Answer: B

Rationale: In a pregnant client at 33 weeks gestation, performing CPR requires tilting the pelvis and thorax at a 30-degree angle to relieve pressure on the vena cava, ensuring proper circulation during compressions. Administering chest compressions at a faster rate (Choice A) may not address the specific needs of a pregnant client in cardiac arrest. Positioning the client flat with legs elevated (Choice C) is not recommended as it can worsen vena cava compression. Calling for immediate assistance and preparing for a cesarean section (Choice D) should be considered only after initiating appropriate CPR modifications.

Correct Answer: D

Rationale: Controlling blood pressure is critical in managing peripheral vascular disease, as elevated pressure can exacerbate vascular damage and complications. While foot care, shoe fit, and exercise are important, lowering blood pressure is a primary goal. Proper blood pressure management helps in preventing further damage to the blood vessels and reduces the risk of complications associated with peripheral vascular disease, making it the most crucial outcome to include in the plan of care for this client.

Correct Answer: B

Rationale: To administer 35 mg of celtazidime from a 100 mg/ml solution, the nurse should give 0.4 ml of the reconstituted celtazidime solution. The calculation is 35 mg / 100 mg/ml = 0.35 ml, but since the vial is 500 mg, the answer is 0.35 ml * (500 mg / 100 mg) = 0.4 ml. Therefore, choices A, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

Correct Answer: B

Rationale: When a client on digoxin reports nausea, it can be a sign of digoxin toxicity. The priority action for the nurse is to assess the client's digoxin level immediately. This assessment will help determine if the nausea is related to digoxin toxicity, requiring a dosage adjustment. Administering an anti-nausea medication (Choice A) does not address the underlying issue of potential digoxin toxicity. Assessing the client's apical pulse (Choice C) is important in general digoxin monitoring but not the first action when nausea is reported. Instructing the client to reduce fluid intake (Choice D) is not the initial response to nausea in a client taking digoxin.

Correct Answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.
