Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. The nurse is caring for the client one day postoperative sigmoid colostomy operation. Which independent nursing intervention should the nurse implement?

• A. Change the infusion rate of the intravenous fluid
• B. Encourage the client to discuss his or her feelings
• C. Administer opioid narcotic medications for pain management
• D. Assist the client out of bed to sit in the chair twice daily

Correct answer: D

Rationale: Assisting the client to sit in a chair is an essential nursing intervention postoperatively as it helps promote circulation, prevent complications like blood clots, and aids in the recovery process. Changing the infusion rate of intravenous fluid (Choice A) requires a physician's order and is not an independent nursing intervention. Encouraging the client to discuss feelings (Choice B) is important for emotional support but not as crucial as physical care immediately postoperatively. Administering opioid narcotic medications (Choice C) for pain management should be based on a prescribed schedule and assessment rather than being an independent nursing action.

3. The hypertonicity of the muscles in an infant with cerebral palsy causes scissoring of the legs. The nurse teaches the mother that the preferred way to carry the infant is in a sitting position:

• A. Astride one of her hips
• B. Strapped in an infant seat
• C. Wrapped tightly in a blanket
• D. Under the arm using a football hold

Correct answer: A

Rationale: Carrying the infant astride one of her hips helps keep the legs apart and can help reduce muscle tightness. This position allows for better support and alignment, preventing further muscle contractures. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm would not provide the same benefits and may even exacerbate muscle tightness in a child with cerebral palsy.

4. What is the best way to manage a patient's intake of dietary fiber?

• A. Increase intake gradually
• B. Increase intake suddenly
• C. Decrease intake abruptly
• D. Maintain a high intake

Correct answer: A

Rationale: The best way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that may arise from a sudden increase in fiber intake. Choice B is incorrect because increasing intake suddenly can lead to digestive issues. Choice C is incorrect as decreasing fiber intake abruptly may not be necessary and can impact overall health. Choice D is incorrect as maintaining a high intake without considering the patient's current intake level can also cause digestive problems.

5. Under the health services support area concept, how is the medical care under the MEDCOM divided?

• A. Six geographical regions of the United States with command authority in each region
• B. Five levels of health service support, each providing different levels of health care services
• C. Primary and secondary health care regions, each containing a MEDDAC or MEDCEN
• D. Eight geographical areas of responsibility designated as health services support regions, each of which is subdivided into two or more health service areas

Correct answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.
