What should a male client taking an anticoagulant be taught to do?

Correct Answer: B

Rationale: The correct answer is B: Avoid foods high in vitamin K. Vitamin K can interfere with the effectiveness of anticoagulants. Teaching the client to avoid foods high in vitamin K, such as leafy greens and broccoli, helps maintain the stability of their blood thinning medication. Reporting incidents of diarrhea (choice A) is important for monitoring side effects but not directly related to anticoagulant therapy. Using a straight razor when shaving (choice C) can increase the risk of cuts and bleeding, which is not ideal for someone on anticoagulants. Taking aspirin for pain relief (choice D) is not recommended as it can increase the risk of bleeding when combined with anticoagulants.

Correct Answer: D

Rationale: The correct answer is D because chronic lymphocytic leukemia is characterized by low platelet counts, not elevated thrombocyte counts. A: Predominance of lymphoblasts is incorrect because CLL involves mature lymphocytes, not lymphoblasts. B: Leukocytosis is incorrect because CLL typically presents with elevated lymphocyte counts. C: Abnormal blast cells in the bone marrow is incorrect as CLL is characterized by mature lymphocytes, not blast cells.

Correct Answer: A

Rationale: The correct answer is A: Manager. When a nurse assumes a position of authority within a formal organization, they are responsible for overseeing operations, resources, and staff to achieve organizational goals. As a manager, the nurse will be involved in decision-making, planning, organizing, and controlling activities within the organization. This role requires skills in delegation, problem-solving, and communication to effectively lead the team. Incorrect choices: B: Advocate - While advocacy is an important aspect of nursing, assuming a position of authority typically involves broader responsibilities beyond advocacy. C: Leader - Leadership qualities are essential for a nurse in a managerial position, but leadership alone does not encompass all the responsibilities of a manager. D: Teacher - Although teaching may be part of a nurse's role, assuming a position of authority within a formal organization usually entails managerial duties rather than solely focusing on teaching responsibilities.

Correct Answer: B

Rationale: The correct answer is B: Down and back. Pulling the external ear down and back in a 5-year-old child straightens the ear canal, allowing for better visualization during otoscope inspection. This technique also helps prevent injury to the ear canal and eardrum. Pulling the ear up and front (choice A) can cause the ear canal to close off, obstructing the view. Pulling the ear down and front (choice C) may not provide adequate visualization and can also lead to injury. Pulling the ear up and back (choice D) can cause the ear canal to fold, making it difficult to see inside.

Correct Answer: B

Rationale: The correct answer is B: Sterile normal saline. Before administering intravenous medication through a medication lock, the nurse should first instill sterile normal saline to ensure patency of the line and prevent clot formation. Normal saline is isotonic and compatible with most medications, helping to maintain hydration and prevent damage to the vein. Sterile bacteriostatic water (choice A) is not appropriate for this purpose. Sterile isopropyl alcohol (choice C) is used for skin preparation, not line maintenance. Sterile hydrogen peroxide (choice D) is too harsh and can cause tissue damage.
