1. 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.

2. In the context of milieu therapy, what is its primary purpose?

• A. exploring the client's perception of reality
• B. enhancing social interaction abilities
• C. addressing maladaptive behaviors
• D. providing routine daily experiences

Correct answer: D

Rationale: Milieu therapy aims to provide routine daily experiences to clients. By offering a structured and predictable environment, it helps individuals feel safe and secure, reducing disruptive behaviors. Exploring the client's perception of reality (choice A) may be part of therapy but not the primary focus. Enhancing social interaction abilities (choice B) and addressing maladaptive behaviors (choice C) are important aspects of therapy but not the primary purpose of milieu therapy.

3. The nurse is making assignments for the day. Which client should be assigned to the pregnant nurse?

• A. The client receiving linear accelerator radiation therapy for lung cancer
• B. The client with a radium implant for cervical cancer
• C. The client who has just been administered soluble brachytherapy for thyroid cancer
• D. The client who returned from placement of iridium seeds for prostate cancer

Correct answer: A

Rationale: The pregnant nurse should not be assigned to any client with radioactivity present. The client receiving linear accelerator therapy is the correct choice because the radiation stays in the department, and the client is not radioactive. Choices B, C, and D involve clients who are radioactive or pose a risk due to radioactivity. The client with a radium implant for cervical cancer (choice B) is radioactive, the client who has just been administered soluble brachytherapy for thyroid cancer (choice C) is radioactive for approximately 72 hours, and the client who returned from placement of iridium seeds for prostate cancer (choice D) is also radioactive, especially right after the procedure. These options are not suitable for assignment to the pregnant nurse.

4. 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.

5. A woman asks, "How much alcohol can I safely drink while pregnant?"? The nurse's best response is:

• A. "The amount of alcohol that is safe during pregnancy is unknown."?
• B. "Consuming one or two beers or glasses of wine a day is considered safe for a healthy pregnant woman."?
• C. "Drinking three or more drinks on any given occasion is the only harmful type of drinking during pregnancy."?
• D. "You can have a drink to help you relax and get to sleep at night."?

Correct answer: A

Rationale: The correct answer is, "The amount of alcohol that is safe during pregnancy is unknown."? This response is appropriate because there is no known safe amount of alcohol consumption during pregnancy. Consuming any amount of alcohol during pregnancy can pose risks to the developing fetus, leading to conditions like fetal alcohol syndrome, which is a combination of mental and physical abnormalities in infants. Choices B, C, and D are incorrect. Choice B suggests that consuming one or two drinks a day is safe during pregnancy, which is not supported by current medical guidelines. Choice C incorrectly states that only drinking three or more drinks on any given occasion is harmful, when in reality, any amount of alcohol can be harmful to the fetus. Choice D is inappropriate as it suggests that having a drink to relax and sleep is acceptable during pregnancy, which is not the case.
