Correct Answer: C

Rationale: The correct answer is C: 2 tbsp of peanut butter. Two tablespoons of peanut butter is approximately equivalent to 4 teaspoons of oil, providing healthy fats in the diet. Choice A, 1 tbsp of soft margarine, is not equivalent to 4 tsp of oil as margarine contains additional ingredients. Choice B, ½ oz of nuts, and choice D, 1 oz of sunflower seeds, do not provide an equivalent amount of oil as requested in the question.

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: A

Rationale: A client with diarrhea should avoid consuming orange juice. Orange juice is high in sugar content, which can worsen diarrhea symptoms by drawing water into the intestines, potentially leading to further dehydration and discomfort. Tuna, eggs, and macaroni are generally well-tolerated and do not exacerbate diarrhea symptoms, making them more suitable food choices for individuals experiencing diarrhea.

Correct Answer: B

Rationale: The correct answer is B: 'The tube will remove excess air from your chest.' In a spontaneous pneumothorax, air accumulates in the pleural space, causing lung collapse. The chest tube is inserted to remove this excess air, allowing the lung to re-expand. Choices A, C, and D are incorrect because the primary purpose of a chest tube in pneumothorax is to evacuate air, not fluid, control air entry, or seal a lung hole.

Correct Answer: B

Rationale: The correct answer is B: Pupils fixed and dilated. Fixed and dilated pupils are a critical neurological sign that indicates severe neurological damage or brain herniation, posing a significant concern for the patient's condition. Flaccid paralysis (choice A) typically indicates lower motor neuron injury, while diminished spinal reflexes (choice C) and reduced sensory responses (choice D) may suggest various neurological issues but are not as acutely concerning as fixed and dilated pupils in this scenario.
