Correct Answer: B

Rationale: For clients with hepatic encephalopathy, foods high in protein like cottage cheese and tuna should be avoided. Plant-based protein sources like beans are recommended due to their lower ammonia production during digestion. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they include high-protein or high-sodium foods that can worsen the condition of hepatic encephalopathy.

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: When a nurse assesses a 1-hour postpartum client with a boggy uterus located 2 cm above the umbilicus, it indicates uterine atony. The first action the nurse should take is to massage the fundus. Fundal massage helps stimulate uterine contractions, which will reduce bleeding and prevent postpartum hemorrhage. Taking vital signs, assessing lochia, or administering an oxytocin IV bolus are important interventions but should come after addressing uterine atony through fundal massage.

Correct Answer: D

Rationale: When caring for a client with a C. difficile infection, it is essential to isolate them in a private room to prevent the spread of spores through contact with surfaces. Placing the client in a negative pressure room (Choice A) is not necessary for C. difficile. Using alcohol-based hand rub (Choice B) and wearing a face shield (Choice C) are important infection control measures but are not specific to the isolation requirements for C. difficile.

Correct Answer: C

Rationale: The correct instruction for a patient starting radiation therapy for esophageal cancer is to wear clothing over the area of radiation treatment. This helps to prevent irritation and protect the skin. Removing dye markings after each treatment (choice A) is unnecessary and not typically part of the patient's self-care. Applying a warm compress (choice B) can exacerbate skin irritation caused by radiation. Using a washcloth to bathe the treatment area (choice D) can potentially irritate the skin further, making it important to avoid.
