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: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.

Correct Answer: A

Rationale: Encouraging the client to use the incentive spirometer 4-5 times per hour is the correct approach post-gallbladder surgery under general anesthesia. This frequency helps prevent respiratory complications, such as atelectasis, by promoting lung expansion. Choices B, C, and D suggest either too few or too many sessions per hour, which may not be optimal for the client's respiratory recovery needs. It is important to strike a balance between ensuring adequate lung expansion and not overexerting the client, which is why 4-5 times per hour is the recommended frequency.

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: A

Rationale: The correct answer is to check the drainage tubing for a kink. A kink in the tubing can obstruct urine flow, potentially causing the low output. By addressing this first, the nurse can ensure that there are no physical obstructions hindering urine drainage. Reviewing the intake and output record is important, but addressing a possible kink in the tubing takes precedence as it directly affects urine flow. Notifying the healthcare provider should be considered after assessing and resolving immediate issues. Giving the client water to drink may be appropriate, but addressing a kink in the tubing is the priority to ensure proper function of the urinary catheter.
