Nursing Elites

1. The use of the antibiotic neomycin may decrease the absorption of:

• A. Iron, copper, and zinc
• B. Protein and amino acids
• C. Fat-soluble vitamins
• D. Water-soluble vitamins

Correct answer: C

Rationale: The correct answer is C. Neomycin can interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K. Choice A is incorrect because neomycin does not affect the absorption of iron, copper, and zinc. Choice B is incorrect as neomycin does not impact the absorption of protein and amino acids. Choice D is also incorrect as neomycin does not decrease the absorption of water-soluble vitamins like vitamin C and the B vitamins.

2. The client is diagnosed with pericarditis. When assessing the client, the nurse is unable to auscultate a friction rub. Which action should the nurse implement?

• A. Notify the healthcare provider
• B. Document that the pericarditis has resolved
• C. Ask the client to lean forward and listen again
• D. Prepare to insert a unilateral chest tube

Correct answer: C

Rationale: The correct action for the nurse to implement when unable to auscultate a pericardial friction rub in a client diagnosed with pericarditis is to ask the client to lean forward and listen again. Leaning forward can help bring the heart closer to the chest wall, making it easier to detect the rub. Option A (Notifying the healthcare provider) is incorrect because further assessment is needed before escalating the situation. Option B (Documenting that the pericarditis has resolved) is incorrect as the absence of a friction rub does not necessarily mean resolution. Option D (Preparing to insert a unilateral chest tube) is incorrect as this intervention is not indicated for the absence of a friction rub.

3. The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion?

• A. Start the transfusion at 10-15 mL per hour for 15-30 minutes
• B. Re-crossmatch the blood until the antibodies are identified
• C. Have the client sign a permit to receive uncrossmatched blood
• D. Have the unlicensed nursing assistant stay with the client

Correct answer: A

Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is essential when the cross-match reveals the presence of antibodies that cannot be cross-matched. This precaution allows the nurse to monitor for any adverse reactions due to the antibodies. Re-crossmatching the blood until the antibodies are identified (choice B) may delay the transfusion process and put the client at risk. Having the client sign a permit to receive uncrossmatched blood (choice C) is not a standard practice and does not address the immediate need for precautions during transfusion. Having the unlicensed nursing assistant stay with the client (choice D) is unrelated to the safe initiation of the transfusion and is not a precaution specific to managing antibodies in blood products.

4. 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.

5. Which risk factor would the nurse expect to find in the client diagnosed with pancreatic cancer?

• A. Chewing tobacco
• B. Low-fat diet
• C. Chronic alcoholism
• D. Exposure to industrial chemicals

Correct answer: C

Rationale: The correct answer is chronic alcoholism. Chronic alcoholism is a significant risk factor for pancreatic cancer due to its impact on the pancreas. Chewing tobacco (choice A) is more associated with oral and throat cancers, not pancreatic cancer. A low-fat diet (choice B) is actually considered a protective factor against pancreatic cancer. Exposure to industrial chemicals (choice D) may be a risk factor for other types of cancer but is not strongly linked to pancreatic cancer.
