Nursing Elites

1. Short-bowel syndrome usually occurs when:

• A. The longitudinal muscles of the intestine contract
• B. More than 50% of the small intestine is surgically removed
• C. More than 50% of the large intestine is surgically removed
• D. Transit time is decreased due to infection or drugs

Correct answer: B

Rationale: Short-bowel syndrome usually occurs when more than 50% of the small intestine is surgically removed. This condition results in malabsorption of nutrients and fluids due to the reduced length of the small intestine. Choice A is incorrect because the contraction of longitudinal muscles does not lead to short-bowel syndrome. Choice C is incorrect as short-bowel syndrome is primarily related to the small intestine, not the large intestine. Choice D is incorrect since decreased transit time due to infection or drugs is not a direct cause of short-bowel syndrome.

2. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

3. 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.

4. The nurse is caring for a client diagnosed with rule-out nephritic syndrome. Which intervention should be included in the plan of care?

• A. Monitor the urine for bright-red bleeding
• B. Evaluate the calorie count of the 500-mg protein diet
• C. Assess the client’s sacrum for dependent edema
• D. Monitor for a high serum albumin level

Correct answer: C

Rationale: The correct intervention to include in the plan of care for a client with rule-out nephritic syndrome is to assess the client’s sacrum for dependent edema. Dependent edema is common in nephritic syndrome due to protein loss, and monitoring for this helps manage the condition. Choices A, B, and D are incorrect. Monitoring the urine for bright-red bleeding may be more relevant for a client with a different condition, such as glomerulonephritis. Evaluating the calorie count of a 500-mg protein diet is not directly related to managing nephritic syndrome. Monitoring for a high serum albumin level does not directly address the symptom of dependent edema associated with nephritic syndrome.

5. Which lipoprotein carries cholesterol from tissues to the liver for excretion?

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.
