Correct Answer: D

Rationale: The correct answer is to restrict protein intake for a client with chronic renal failure. In renal failure, the kidneys are unable to effectively filter waste products. Excessive protein intake can lead to the accumulation of waste products, increasing the workload on the kidneys. Therefore, restricting protein intake is essential to prevent further kidney damage. Choices A, B, and C are incorrect. Increasing calcium intake is not specifically indicated for chronic renal failure. Increasing potassium intake can be dangerous in renal failure as impaired kidneys may not be able to excrete excess potassium. Increasing protein intake is contraindicated in chronic renal failure as it can worsen kidney function and increase the accumulation of waste products.

Correct Answer: C

Rationale: Montelukast is a leukotriene receptor antagonist that helps reduce swelling and mucus production in the airways, making it useful for long-term asthma management.

Correct Answer: A

Rationale: The correct answer is A: Spinach. Spinach is rich in calcium, making it a suitable choice for individuals with lactose intolerance who need to avoid dairy products. Peanut butter, ground beef, and carrots are not significant sources of calcium compared to spinach, and therefore, not the best recommendation for increasing calcium intake in lactose-intolerant individuals.

Correct Answer: B

Rationale: The correct answer is B because numb fingers indicate neurovascular compromise, which can lead to serious complications if not addressed promptly. The priority in this situation is to assess and address any circulation issues affecting the extremity. Choices A, C, and D are of concern but not as immediate as neurovascular compromise, which requires urgent attention to prevent further complications.

Correct Answer: C

Rationale: The correct answer is C. The client with hypothyroidism who is stuporous should be assessed first as this may indicate a critical condition, possibly related to severe hypothyroidism. Stupor is a state of near-unconsciousness or insensibility, suggesting a decline in neurological function that requires immediate evaluation. Choices A, B, and D do not present with immediate life-threatening conditions that require urgent assessment. While chemotherapy, post-appendectomy complications, and burn care are important, they do not pose the same level of immediate risk as a stuporous client.
