A family came to the emergency department with complaints of food poisoning. Which client should the nurse see first?

Correct Answer: B

Rationale: The correct answer is B because a 2-year-old with reduced urine output (1 wet diaper in 24 hours) is at high risk for dehydration. Dehydration can occur rapidly in young children and can be life-threatening. The nurse should prioritize assessing and managing the dehydration of the 2-year-old. Choices A, C, and D, although they may also require attention, do not present the same level of immediate risk as a dehydrated 2-year-old.

Correct Answer: D

Rationale: Enteral feedings are commonly used in patients with Crohn's disease during acute exacerbations to provide adequate nutrition while resting the bowel. Acute cholecystitis, hepatic encephalopathy, and ulcerative colitis in remission wouldn't typically require enteral feedings as the primary nutritional support. Acute cholecystitis may necessitate fasting and intravenous fluids, hepatic encephalopathy may require dietary modifications but not enteral feedings, and patients with ulcerative colitis in remission usually have their nutritional needs met through a regular diet.

Correct Answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

Correct Answer: A

Rationale: Aspirin is best absorbed on an empty stomach to maximize its effectiveness. Taking it with cold water helps to enhance absorption. Choice B is incorrect as taking aspirin on a full stomach may reduce its absorption. Choice C is incorrect as fruit juice can sometimes interact with medications. Choice D is incorrect as taking aspirin first thing in the morning may not optimize its absorption.

Correct Answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys may not effectively filter excess potassium from the blood, leading to hyperkalemia. Calcium, iron, and zinc do not need to be avoided specifically in chronic renal failure unless there are other underlying reasons or complications.
