Correct Answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.

Correct Answer: C

Rationale: The correct response is to offer the client several choices of times to bathe during the day. This approach respects the client's religious beliefs while ensuring that hygienic practices are still maintained. By providing options, the nurse can work together with the client to find a solution that aligns with both his beliefs and his health needs. Choice A is incorrect because solely reviewing the importance of hygiene may not address the client's specific religious concerns. Choice B is inappropriate as it disregards the client's beliefs and autonomy. Choice D is not the best approach as it may come off as confrontational or dismissive of the client's beliefs, rather than working collaboratively to find a suitable solution.

Correct Answer: B

Rationale: When a newborn presents with a yellowish tint to the skin, it can indicate jaundice, which is caused by elevated bilirubin levels. Monitoring the infant's bilirubin levels is crucial to assess the severity of jaundice and determine the need for further intervention. Reassuring the parents without proper assessment could lead to delayed treatment if jaundice is present. Increasing the frequency of feedings may not address the underlying cause of jaundice. Administering phototherapy is a treatment option that should be based on bilirubin level assessment and healthcare provider's recommendation.

Correct Answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing in COPD patients. While administering bronchodilator therapy as prescribed (Choice A) is important, it is not the priority in this scenario. Encouraging deep breathing and coughing exercises (Choice B) can be beneficial but do not take precedence over positioning for improved respiratory function. Increasing the oxygen flow rate (Choice D) can be considered after the initial positioning to relieve respiratory distress, making it a later intervention.

Correct Answer: C

Rationale: In this scenario, the correct intervention is to outline the area with ink and check it every 15 minutes to monitor for changes in bleeding. This approach helps in assessing the extent and progression of the bleeding. Option A is incorrect because assessing hemoglobin levels would not provide immediate information on the ongoing bleeding. Option B is premature without first monitoring the bleeding site. Option D is incorrect because although some postoperative bleeding can be expected, fresh bleeding on the cast warrants immediate monitoring and evaluation.
