Correct Answer: A

Rationale: The correct answer is A: Hyperglycemia. The patient's symptoms like lethargy, thirst, headache, increased urination are indicative of high blood sugar levels. Lethargy is a common symptom of hyperglycemia due to the body's inability to use glucose effectively. Thirst and increased urination occur as the body tries to get rid of excess glucose through urine. Headache can result from dehydration due to increased urination. To address hyperglycemia, the nurse may need to adjust the patient's parenteral nutrition, monitor blood glucose levels, and potentially administer insulin. Incorrect choices: B: Hypoglycemia - Symptoms of hypoglycemia include sweating, confusion, and shakiness, which are not present in this case. C: Hypercapnia - This is high carbon dioxide levels in the blood, typically caused by respiratory issues, not related to the symptoms described. D: Hypocapnia - This is low carbon dioxide levels

Correct Answer: D

Rationale: The correct answer is D: According to current guidelines, breast conservation combined with radiation is as effective as a modified radical mastectomy. 1. Breast conservation surgery followed by radiation is a standard treatment option for early-stage breast cancer. 2. Studies have shown that breast conservation surgery combined with radiation therapy is equally effective in terms of long-term survival rates compared to mastectomy. 3. Current guidelines recommend considering breast conservation surgery as a viable option for patients with early-stage breast cancer. 4. Modified radical mastectomy is not necessarily needed to ensure complete removal of cancer, as breast conservation surgery followed by radiation can achieve the same goal. 5. Therefore, the nurse should reassure the patient's husband that the recommended treatment plan is based on current guidelines and is as effective as a modified radical mastectomy.

Correct Answer: B

Rationale: The correct answer is B: Mitral valve prolapse. This condition is usually benign during pregnancy because the heart's workload increases, and the mitral valve is a one-way valve that prevents blood from flowing back into the left atrium. Mitral valve prolapse typically does not significantly affect the heart's ability to pump blood efficiently during pregnancy. Rationale: 1. Cardiomyopathy (A) can worsen during pregnancy, leading to complications for both the mother and the fetus. 2. Rheumatic heart disease (C) can cause valve damage, increasing the risk of complications during pregnancy. 3. Congenital heart disease (D) varies in severity and can pose risks during pregnancy, depending on the specific condition. Summary: Mitral valve prolapse is the correct answer as it is less likely to cause significant issues during pregnancy compared to the other options provided.

Correct Answer: C

Rationale: The correct answer is C: Protecting the safety of the patient, family, and staff. This is the priority when planning care for a patient undergoing radiation therapy due to the potential risks of radiation exposure to others. Ensuring safety involves implementing proper radiation safety protocols, educating the patient and family on safety measures, and providing a safe environment for all. Choices A, B, and D are incorrect. Preventing hemorrhage is important but not the top priority during radiation therapy. Ensuring the patient understands the treatment's purpose is essential but not the immediate priority. Adherence to dietary restrictions is important for overall health but is not the primary focus when prioritizing actions for radiation therapy.
