Correct Answer: B

Rationale: When a client is admitted with decreased circulation in the left leg, the most critical initial nursing action is to evaluate the pedal pulses. Pedal pulses provide essential information about the circulation status in the affected leg. Assessing the client's mobility (Choice A) is important but not as crucial as evaluating pedal pulses in this scenario. Monitoring skin temperature (Choice C) and checking for swelling (Choice D) are also relevant, but they are secondary to evaluating pedal pulses since the latter directly assesses the circulation in the affected limb.

Correct Answer: A

Rationale: The correct answer is A. Stress typically increases blood glucose levels due to the release of stress hormones like cortisol and adrenaline. Elevated blood glucose helps provide energy for the body to cope with the stressful situation. Choice B is incorrect because intestinal peristalsis, the movement of the intestines, is more likely to decrease under stress due to the 'fight or flight' response. Choice C is incorrect as peripheral blood vessels' diameter may vary in response to stress, with both constriction and dilation possible. Choice D is incorrect as urine output may increase or decrease depending on individual differences and the specific stress response, but it is not a typical or direct physiological response to stress.

Correct Answer: A

Rationale: The correct first action for the nurse to take is to check the IV tubing for obstruction. This step is crucial in ensuring that the IV fluids are flowing properly and that there are no blockages preventing the correct infusion rate. Increasing the flow rate (Choice B) without confirming the tubing's status could lead to potential complications if there is indeed an obstruction. Changing the IV site (Choice C) is not the priority in this situation unless there are specific clinical indications. Notifying the physician (Choice D) can be done after checking the tubing for obstruction, as the physician may need to be informed depending on the findings.

Correct Answer: B

Rationale: The correct initial action when an IV line infiltrates is to discontinue the IV and restart it in another site. This is crucial to prevent complications such as tissue damage, phlebitis, and infection that can result from the infiltration. Applying a warm compress (Choice A) is not recommended as it can exacerbate the tissue damage caused by the infiltration. Aspirating the IV line and flushing it with normal saline (Choice C) is not appropriate for an infiltrated IV line as it does not address the main issue of infiltration. While notifying the healthcare provider (Choice D) is important, the immediate priority is to discontinue the infiltrated IV to prevent further harm and ensure proper delivery of fluids or medications.

Correct Answer: A

Rationale: The appropriate initial action for the nurse is to examine the elbow. This step is crucial to assess the site of pain, identify any visible signs of injury or inflammation, and determine the cause of the discomfort. Administering pain medication (Choice B) should come after a thorough assessment. Applying a warm compress (Choice C) might provide temporary relief but does not address the underlying cause. Assessing the client's range of motion (Choice D) is important but would come after the initial examination to further evaluate the elbow joint.
