Correct Answer: B

Rationale: The correct answer is B: Hamburger, fries, and soft drink. This meal is considered the least nutritious among the options provided due to its high content of unhealthy fats, processed carbohydrates, and added sugars, which lack essential nutrients. On the other hand, choice A: Ham sandwich, apple, and milk, offers a balanced meal with protein, fiber, vitamins, and calcium. Choice C: Macaroni and cheese, green beans, and peaches, provides a mixture of carbohydrates, vegetables, and fruits. Choice D: Meatloaf, broccoli, and pear slices, includes protein, fiber, and vitamins. Thus, all choices except B provide a more balanced and nutritious meal.

Correct Answer: D

Rationale: When measuring blood pressure, the cuff should be inflated to 30 mmHg above the estimated systolic blood pressure based on palpation of the radial or brachial artery. This ensures an accurate blood pressure measurement. Choices A, B, and C are incorrect. Deflating the cuff fully before starting a second reading (Choice A) does not directly relate to the position of the cuff during a reading. Deflating the cuff quickly after inflating to 180 mmHg (Choice B) is not recommended because it can potentially lead to inaccurate readings. While ensuring the cuff is large enough to wrap around the upper arm positioned 1 cm above the brachial artery is important (Choice C), this alone does not guarantee an accurate blood pressure reading. The correct inflation based on palpation is the key element for accuracy, which is why Choice D is correct.

Correct Answer: B

Rationale: In preparing a patient for a cleansing enema, the nurse typically positions the patient in the left lateral position. This position allows for the best flow of the solution due to the anatomical configuration of the colon. The right lateral position, right Sim's position, and left Sim's position are not typically used for this procedure. The rationale provided initially is incorrect as it pertains to lung expansion and postural drainage, which are not relevant to a cleansing enema procedure.

Correct Answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is Orthopnea. Orthopnea is a medical condition in which a person has difficulty breathing while lying down. To alleviate this difficulty, the person may need to sit, stand, or use multiple pillows. On the other hand, Dyspnea refers to general shortness of breath which is not specifically related to the position of the body. Eupnea is the term for normal, unlabored breathing, and Apnea is a condition characterized by the cessation of breathing. Thus, none of these other choices directly relate to the need to adjust body position or use aids like multiple pillows to breathe comfortably when lying down.
