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 term the nurse will use to report scaling of the scalp is 'Dandruff.' Dandruff is characterized by scaling of the scalp that is often accompanied by itching. Choice B, 'Alopecia,' refers to hair loss, not scaling. Choice C, 'Pediculosis,' is the infestation of lice, not scaling. Choice D, 'Xerostomia,' pertains to dry mouth, which is unrelated to the described symptom of scaling of the scalp.

Correct Answer: A

Rationale: The correct action is to commend the client for selecting a high biological value protein, as scrambled eggs provide a good protein source for clients with chronic renal failure. Protein is essential for maintaining muscle mass and overall health in these clients. Reminding the client to avoid protein is incorrect as it may lead to protein-energy malnutrition, which is a common concern in chronic renal failure. Suggesting orange juice for absorption is not relevant to the situation, as protein absorption is not a primary concern in this context. Encouraging the client to attend classes on dietary management of chronic renal failure is important for overall education but is not the immediate action needed in response to the client's breakfast choice.

Correct Answer: C

Rationale: When a nurse obtains a blood pressure reading that is elevated, the appropriate action is to recheck the client's BP and measure the other arm for comparison. This step helps ensure accuracy by ruling out errors like improper cuff size, positioning, or equipment malfunction. Repositioning the client supine is not necessary unless the client shows signs of distress or symptoms. Ensuring the appropriate cuff width is important for accurate readings but does not address the immediate need to confirm the current BP. Requesting another nurse to check the BP in 30 minutes delays immediate action and does not address the need for verification and comparison of the current reading.

Correct Answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
