Nursing Elites

1. The physician orders the antibiotics ampicillin (Omnipen) and gentamicin (Garamycin) for a newly admitted client with an infection. The nurse should:

• A. administer both medications simultaneously.
• B. give the medications sequentially, and flush well between them.
• C. ask the physician or pharmacy which medication to give first and how long to wait before giving the other drug.
• D. start one medication now and begin the other medication in 2-4 hours.

Correct answer: B

Rationale: A client with an infection needs both antibiotics as soon as possible. However, the pH of ampicillin is 8-10, and the pH of gentamicin is 3-5.5, making them incompatible when given together. Flushing well between drugs is necessary to prevent interaction. Choice C is incorrect because the nurse, not the physician or pharmacy, should determine the correct administration sequence. Consulting with the pharmacist is appropriate if uncertain. Choice D is incorrect because delaying the second medication by several hours can slow the treatment of the client's infection, as both antibiotics are needed promptly to address the infection effectively. Therefore, the correct action is to give the medications sequentially and flush well between them to prevent any potential interactions.

2. Hormonal agents are used to treat some cancers. An example is:

• A. thyroxine to treat thyroid cancer.
• B. ACTH to treat adrenal carcinoma.
• C. estrogen antagonists to treat breast cancer.
• D. glucagon to treat pancreatic carcinoma.

Correct answer: C

Rationale: Estrogen antagonists are commonly used to treat estrogen hormone-dependent cancers such as breast carcinoma. One well-known estrogen antagonist used in breast cancer therapy is Tamoxifen (Nolvadex). This drug, in combination with surgery and other chemotherapeutic drugs, reduces breast cancer recurrence by 30%. Estrogen antagonists can also be administered to prevent breast cancer in women who have a strong family history. Thyroxine is a thyroid hormone used to treat hypothyroidism, not thyroid cancer. ACTH is an anterior pituitary hormone that stimulates the adrenal glands to release glucocorticoids; it does not treat adrenal cancer. Glucagon is a pancreatic alpha cell hormone that stimulates glycogenolysis and gluconeogenesis; it does not treat pancreatic cancer.

3. Which laboratory test would be the least effective in diagnosing a myocardial infarction?

• A. AST
• B. Troponin
• C. CK-MB
• D. Myoglobin

Correct answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

4. Six hours after birth, the infant is found to have an area of swelling over the right parietal area that does not cross the suture line. The nurse should chart this finding as:

• A. A cephalohematoma
• B. Molding
• C. Subdural hematoma
• D. Caput succedaneum

Correct answer: A

Rationale: The correct answer is A, a cephalohematoma. A cephalohematoma is an area of bleeding outside the cranium but beneath the periosteum, typically not crossing the suture line. Answer B, molding, is the overlapping of the bones of the cranium and does not involve bleeding, making it an incorrect choice. Answer C, a subdural hematoma, involves intracranial bleeding and is typically diagnosed through imaging studies like a CAT scan or x-ray. Answer D, caput succedaneum, is characterized by edema that crosses the suture line, unlike the described swelling in this case.

5. A client who recently lost 50 pounds just received news that she is pregnant. A possible nursing diagnosis is:

• A. Actual Chronic Low Self-Esteem (related to obesity).
• B. Potential Chronic Low Self-Esteem (related to obesity).
• C. Actual Situational Low Self-Esteem (related to fear of weight regain and pregnancy).
• D. Potential Situational Low Self-Esteem (related to fear of weight regain and pregnancy).

Correct answer: D

Rationale: In this scenario, the client's recent weight loss and subsequent pregnancy could lead to concerns about weight regain and body image. The most appropriate nursing diagnosis is 'Potential Situational Low Self-Esteem (related to fear of weight regain and pregnancy).' This diagnosis reflects the client's potential emotional response to the fear of losing the progress achieved through weight loss and dealing with changes in body image due to pregnancy. Options A and C imply that low self-esteem is already present, which is not supported by the information given. Option B is not as suitable as the client's self-esteem issues are more related to the fear of weight regain and pregnancy, making option D the best choice.
