Correct Answer: B

Rationale: The correct answer is B: Ineffective airway clearance related to obstruction by a tumor or secretions. This is the highest priority because compromised airway clearance can lead to life-threatening complications such as respiratory distress or hypoxia. Ensuring effective airway clearance is crucial in preventing respiratory compromise and maintaining oxygenation. Choices A, C, and D are not the highest priority because they do not directly address the immediate risk to the client's physiological well-being. Treating disturbed body image, anxiety, or imbalanced nutrition are important but can be addressed after ensuring the client's airway is clear and they are able to breathe effectively.

Correct Answer: A

Rationale: The correct answer is A because maintaining consistency in the order of drawing different types of insulin into the syringe helps prevent medication errors. When mixing insulins, drawing them in the same sequence ensures the correct dose and prevents contamination. Explanation: A: Following the same order ensures accurate dosing and minimizes the risk of mixing up insulins. B: Shaking the vial can cause air bubbles which can affect the accuracy of the dose. C: Storing insulin in the freezer can damage the medication and alter its effectiveness. D: Cloudiness in intermediate-acting insulin is normal and does not indicate it should be discarded.

Correct Answer: C

Rationale: The correct answer is C because morning administration of prednisone mimics the body's natural corticosteroid secretion pattern. Cortisol, a natural corticosteroid, is typically highest in the morning and decreases throughout the day. By taking prednisone in the morning, the client aligns the drug's peak concentration with the body's natural cortisol levels, optimizing its therapeutic effects. Choice A is incorrect because while taking the drug at the same time daily is important for consistency, it does not specifically address the rationale for morning administration. Choice B is incorrect as the effectiveness of prednisone is not solely dependent on its half-life but also on alignment with the body's natural rhythm. Choice D is also incorrect as prednisone can be taken with food and does not necessarily require an empty stomach for optimal absorption.

Correct Answer: B

Rationale: The correct answer is B: Communicating the client’s progress to the interdisciplinary team. During the evaluation phase, the nurse plays a crucial role in ensuring continuity of care by effectively communicating the client’s progress to the interdisciplinary team. This action allows for collaborative decision-making based on the latest information, promotes coordination of care, and ensures that all team members are informed and involved in the client's care plan. Rewriting the care plan (A) is important but may not be the most immediate action during the evaluation phase. Reassessing the client (C) is valuable for gathering additional data but may not directly contribute to continuity of care during this phase. Providing emotional support (D) is essential but may not specifically address continuity of care during evaluation.

Correct Answer: D

Rationale: The correct answer is D: Tensilon test. The Tensilon test involves administering edrophonium (Tensilon) to temporarily improve muscle weakness in myasthenia gravis patients, confirming the diagnosis. Other choices are incorrect: A (Mestinon test) is not a standard diagnostic test for myasthenia gravis, B (Pulmonary function studies) are not specific for myasthenia gravis, and C (Quinine tolerance test) is not a relevant test for this condition.
