Correct Answer: A

Rationale: Clients with neutropenia should avoid foods that may be contaminated to prevent infections. Increasing fluid intake is important to stay hydrated, but it's crucial to use safe sources like bottled water to reduce the risk of infection. Choices B, C, and D are not appropriate for a client with neutropenia. Salad bars may contain raw or unwashed produce, soft-boiled eggs may carry a risk of contamination, and buffets may have food items that are not recommended for someone with neutropenia.

Correct Answer: C

Rationale: Black, tarry stools can indicate gastrointestinal bleeding, which is a serious complication of peptic ulcer disease. This finding suggests active bleeding in the gastrointestinal tract, requiring immediate attention. A normal heart rate of 72 beats per minute (choice A) is within the expected range. A hemoglobin level of 12 g/dL (choice B) is also within normal limits. Nausea and vomiting (choice D) are common symptoms associated with peptic ulcer disease but may not necessarily indicate active bleeding like black, tarry stools.

Correct Answer: A

Rationale: Peanut butter and enriched bread provide complementary proteins, which are important for a vegetarian diet. Peanut butter is a good source of protein and when paired with enriched bread, it forms a complete protein source. Choice B, baked potato with sour cream, lacks complete protein. Choice C, bagel with cream cheese, also does not provide a complete protein source. Choice D, fruit salad and carrot sticks, do not contain sufficient protein to serve as a main protein source for a vegetarian diet.

Correct Answer: C

Rationale: When a client is receiving intravenous antibiotics, checking the IV site for signs of phlebitis is a priority assessment for the nurse. Phlebitis is an inflammation of the vein, which can lead to serious complications such as infection and thrombosis. Monitoring the IV site helps prevent these complications and ensures the safe delivery of antibiotics. While monitoring the client's temperature, pain level, and respiratory status are important assessments, they are not the priority in this scenario where IV antibiotic administration requires close monitoring for complications like phlebitis.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia increases the risk of dysrhythmias when taking digoxin, making potassium intake crucial. Digoxin toxicity is more likely in patients with low potassium levels, leading to an increased risk of dysrhythmias. Choices B, C, and D are incorrect because hypokalemia in combination with digoxin is primarily associated with dysrhythmias rather than oliguria, irritability, anxiety, or alteration of consciousness.
