Correct Answer is A

Explanation

- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.

- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.

- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.

- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

A. Organizing the work environment B. Delegating assigned tasks appropriately C. Making a list of activities to complete D. Rewarding yourself for accomplishing goals

Correct Answer is C

Explanation

- A. Incorrect. Organizing the work environment is an important step of the time management process, but it is not the priority. The nurse manager should first identify the activities that need to be done before organizing them.

- B. Incorrect. Delegating assigned tasks appropriately is an important step of the time management process, but it is not the priority. The nurse manager should first determine which tasks can be delegated and which ones require their direct involvement before assigning them to others.

- C. Correct. Making a list of activities to complete is the priority step of the time management process, as it helps the nurse manager to identify and prioritize their goals and responsibilities.

- D. Incorrect. Rewarding yourself for accomplishing goals is an important step of the time management process, but it is not the priority. The nurse manager should first complete the tasks that are essential and urgent before rewarding themselves for their achievements.
