Correct Answer: C

Rationale: The correct answer is C: General to specific assessment. In this scenario, the nurse is starting the assessment by examining a specific aspect (surgical dressing with drainage) and will likely proceed to gather more detailed information based on the initial findings. This approach involves moving from a broad overview to specific details, which is essential in assessing postoperative patients for complications. A: Gordon’s Functional Health Patterns is a comprehensive assessment framework that covers various aspects of an individual's health, not specifically focusing on the progression from general to specific assessments in this situation. B: Activity-exercise pattern assessment focuses on the patient's activity levels and exercise routines, which is not the primary focus of the scenario described. D: Problem-oriented assessment is a method that involves identifying and addressing specific health issues or concerns, which is not the primary aim of the assessment approach used by the nurse in this scenario.

Correct Answer: D

Rationale: The correct answer is D, Leucovorin. Leucovorin is administered with methotrexate to protect normal cells from methotrexate toxicity by acting as a "rescue" agent. Methotrexate inhibits dihydrofolate reductase, leading to decreased levels of tetrahydrofolate needed for DNA synthesis. Leucovorin bypasses this step by directly providing the reduced form of folic acid, thus preventing toxicity in normal cells. Probenecid (choice A) is not used to protect normal cells during methotrexate therapy. Cytarabine (choice B) and Thioguanine (choice C) are not rescue agents for methotrexate toxicity.

Correct Answer: D

Rationale: The correct answer is D: Draw up clear insulin first when mixing two types of insulin in one syringe. This is important because mixing insulin requires drawing up the clear (short-acting) insulin first to prevent contamination. This ensures accurate dosing and prevents clouding of the insulin. Drawing up cloudy insulin first can lead to inaccurate dosing and potential mixing errors. Administering insulin after the first meal (choice A) is not the focus of this question. Administering insulin at a 45-degree angle into the deltoid muscle (choice B) is not recommended for insulin injections. Vigorously shaking the vial of insulin before withdrawal (choice C) can cause bubbles and affect the accuracy of the dose.

Correct Answer: B

Rationale: The correct answer is B: Offering emotional support. In the preoperative phase, a nurse's role includes comforting and reassuring the patient to reduce anxiety and promote emotional well-being. This is crucial for the patient's overall experience and can positively impact their recovery. Obtaining preoperative orders (A) is typically the responsibility of the physician. Explaining the surgical procedure (C) is usually done by the surgeon. Providing informed consent (D) involves ensuring the patient understands the risks and benefits of the procedure, which is typically the responsibility of the healthcare provider performing the procedure.

Correct Answer: C

Rationale: The correct answer is C: Time-lapsed assessment. This type of assessment involves comparing baseline data with new data collected at a later time to evaluate changes in the client's condition. In this scenario, the nurse is reassessing the client a month later to determine if there have been any changes that require adjustments to the care plan. A: Comprehensive assessment is an in-depth assessment done initially to gather detailed information about the client's overall health status. B: Focused assessment is done to gather specific information related to a particular problem or issue. D: Emergency assessment is performed in urgent situations to quickly identify and address life-threatening conditions.
