Correct Answer: B

Rationale: The correct answer is B: 1 medium orange. Oranges are well-known for being rich in vitamin C, an essential nutrient for immune function and skin health. While choices A, C, and D also contain some vitamin C, the medium orange provides a higher amount of this vitamin compared to a ½ cup of green pepper, ½ cup of cabbage, or a medium tomato.

Correct Answer: D

Rationale: Restlessness is often a sign of respiratory distress or secretion build-up, indicating the need for suctioning. While drowsiness (choice A) can be a sign of hypoxia, it is not as immediate an indication for suctioning as restlessness. Complaint of nausea (choice B) and a pulse rate of 92 (choice C) are not directly related to the need for suctioning in a client on a volume-cycled ventilator.

Correct Answer: B

Rationale: The correct answer is B: Sliced turkey sandwich and canned pineapple. This lunch choice is suitable for a client with congestive heart failure as it is low in sodium. Sliced turkey is a lean protein choice, and canned pineapple is a low-sodium fruit option. Choice A contains high-sodium items like cheese and 2% milk. Choice C includes a cheeseburger, which is typically high in sodium, and a baked potato could also be high in sodium depending on preparation. Choice D consists of mushroom pizza and ice cream, both of which can be high in sodium, especially in processed or restaurant-prepared forms.

Correct Answer: A

Rationale: The correct answer is A: Non-steroidal anti-inflammatory drugs (NSAIDs). When a client is on Coumadin therapy, NSAIDs should be avoided because they can increase the risk of bleeding due to their antiplatelet effects. Choices B, C, and D are incorrect. Cough medicines with guaifenesin, histamine blockers, and laxatives containing magnesium salts do not have a significant interaction with Coumadin therapy that would necessitate avoidance.

Correct Answer: B

Rationale: The correct answer is to assess for dyspnea or stridor. In burn cases involving the face, neck, or chest, there is a risk of airway compromise due to swelling. Dyspnea (difficulty breathing) or stridor (noisy breathing) can indicate airway obstruction or respiratory distress, which requires immediate intervention. Covering the burns with dry sterile dressings (choice A) can be important but ensuring airway patency takes precedence. Initiating intravenous therapy (choice C) may be necessary but not the priority over assessing the airway. Administering pain medication (choice D) is important for comfort but should come after ensuring the airway is clear and breathing is adequate.
