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: 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: B

Rationale: The correct answer is to obtain a health and dietary history when assessing constipation in elders. This action is crucial as it helps the nurse identify potential causes and contributing factors to constipation in elderly clients. Obtaining a complete blood count (choice A) may be necessary at some point, but it is not the priority in this situation. Referring to a provider for a physical examination (choice C) and measuring height and weight (choice D) are important but are not the priority actions when assessing constipation.

Correct Answer: D

Rationale: The correct answer is D: 12 months. Whole milk should be introduced at 12 months to ensure the infant's digestive system can handle the increased fat content. Introducing whole milk before 12 months can lead to digestive issues and potential allergies. Choices A, B, and C are incorrect because transitioning to whole milk before 12 months is not recommended for infants due to their digestive system still developing and not being able to handle the higher fat content of whole milk.

Correct Answer: B

Rationale: The correct answer is B. Drinking coffee throughout the day can aggravate gastroesophageal reflux symptoms.
