Correct Answer: B

Rationale: Leukopenia should take priority in planning care for a client receiving external beam radiation to the mediastinum for bronchial cancer because it is a serious side effect that increases the risk of infection. Monitoring leukopenia is crucial to prevent complications. Esophagitis, fatigue, and skin irritation are also potential side effects of radiation therapy, but leukopenia poses a higher risk of life-threatening infections, requiring immediate attention.

Correct Answer: B

Rationale: When the high-pressure alarm on a ventilator goes off, the nurse's initial action should be to perform a quick assessment of the client's condition. This assessment helps in promptly identifying the cause of the alarm, such as mucus plugging, kinking of the tubing, or other issues. By assessing the client first, the nurse can determine the appropriate intervention needed to address the alarm. Choices A and D are incorrect because disconnecting the client from the ventilator or pressing the alarm reset button should not be the initial actions without assessing the client's condition. While calling the respiratory therapist for help could be beneficial, assessing the client's condition should be the nurse's priority to address the immediate concern.

Correct Answer: D

Rationale: The correct answer is D. A baked potato is high in potassium and helps prevent digitalis toxicity by maintaining adequate potassium levels. While choices A, B, and C all contain some potassium, a baked potato is a more concentrated source of potassium compared to three apricots, a medium banana, or a naval orange. Therefore, the client should choose a baked potato to better meet the dietary needs for preventing digitalis toxicity.

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: D

Rationale: The correct answer is D: 1 cup of kale. Kale is rich in calcium, making it a suitable choice to increase calcium intake for individuals with osteoporosis. While fruits like apples (choice A) are nutritious, they are not high in calcium. Lean beef (choice B) is a good source of protein but not a significant source of calcium. Cream cheese (choice C) is also not a primary source of calcium compared to kale.
