Correct Answer: B

Rationale: The correct answer is B because administration of the diuretic furosemide without saline is not recommended for managing hypercalcemia. Furosemide can lead to volume depletion and potentially exacerbate hypercalcemia by concentrating calcium levels in the blood. A: Fluid administration helps dilute calcium levels by increasing urine output. C: Inorganic phosphate salts can bind with calcium in the gut, reducing absorption. D: Intravenous phosphate therapy can help lower calcium levels by promoting calcium-phosphate complex formation. In summary, B is incorrect as it may worsen hypercalcemia, while A, C, and D are valid strategies for managing hypercalcemia.

Correct Answer: C

Rationale: The correct answer is C: Abdominal girth. Serum albumin helps to increase oncotic pressure in the blood vessels, reducing fluid leakage into the abdomen and decreasing ascites, leading to a decrease in abdominal girth. Option A is incorrect because serum albumin does not directly affect urinary output. Option B is incorrect as serum albumin does not directly impact serum ammonia levels. Option D is incorrect because while serum albumin can help improve liver function, it does not directly treat hepatic encephalopathy.

Correct Answer: D

Rationale: The correct answer is D: Sitting up leaning slightly forward. This position helps prevent blood from flowing back into the throat, reducing the risk of choking and aspiration. It also allows for better drainage of blood out of the nose. Lying down with feet elevated (choice A) can increase blood flow to the head and worsen the nosebleed. Sitting up with neck extended (choice B) can lead to blood flowing into the throat. Lying down with a small pillow under the head (choice C) may cause blood to flow backward.

Correct Answer: B

Rationale: The correct answer is B: Ask the patient to describe the type of reaction. This is the first action the nurse should take because it helps determine the severity of the allergy and how to best proceed with care. By understanding the specific type of reaction the patient experiences, the nurse can implement appropriate precautions and interventions to prevent any adverse reactions during the patient's stay. Choice A is incorrect because placing the patient in isolation is not necessary for a latex allergy. Choice C is incorrect as terminating the interview is premature and does not address the patient's allergy. Choice D is also incorrect as documenting the allergy is important but not the first action to take when assessing a patient's allergic reaction.

Correct Answer: C

Rationale: The correct initial treatment for stage IV ovarian cancer is major surgery (Choice C). This is because at this advanced stage, surgery is typically performed to debulk the tumor and remove as much cancerous tissue as possible, followed by chemotherapy to target any remaining cancer cells. Radiation therapy (Choice A) is not typically the initial treatment for ovarian cancer. Chemotherapy (Choice B) is often used in combination with surgery, but surgery is usually the first line of treatment for stage IV disease. Choosing no treatment (Choice D) would be detrimental as the cancer is advanced and requires immediate intervention.
