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 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: The correct way to carry an infant with cerebral palsy experiencing muscle hypertonicity and scissoring of the legs is astride one of the mother's hips. This position helps keep the infant's legs apart, reducing muscle tightness. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm does not address the specific needs related to muscle hypertonicity and scissoring of the legs in cerebral palsy.

3. A patient with Crohn’s disease is experiencing diarrhea. Which dietary recommendation is appropriate?

• A. High-fiber diet
• B. Low-residue diet
• C. High-fat diet
• D. High-protein diet

Correct answer: B

Rationale: A low-residue diet is appropriate for a patient with Crohn’s disease experiencing diarrhea because it helps reduce bowel movements and manage symptoms. Choice A, a high-fiber diet, can exacerbate diarrhea in Crohn’s disease due to increased bulk and fermentation in the gut. Choice C, a high-fat diet, may be hard to digest and can worsen symptoms. Choice D, a high-protein diet, can be taxing on the digestive system and may not provide the relief needed for diarrhea in Crohn’s disease.

4. Which dietary change is most beneficial for a patient with hypertension?

• A. Increased sodium intake
• B. Decreased potassium intake
• C. Increased fiber intake
• D. Increased cholesterol intake

Correct answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increased sodium intake (choice A) is not recommended as it can raise blood pressure. Decreasing potassium intake (choice B) is not advisable as potassium helps regulate blood pressure. Increased cholesterol intake (choice D) is also not recommended as high cholesterol levels can contribute to cardiovascular issues, including hypertension.

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.
