Nursing Elites

1. A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary mechanism of action for this medication?

• A. Raloxifene decreases bone resorption, which helps to maintain or increase bone density.
• B. Raloxifene increases calcium absorption in the intestines, which helps build stronger bones.
• C. Raloxifene stimulates new bone formation by increasing osteoblast activity.
• D. Raloxifene decreases calcium excretion by the kidneys, helping to maintain bone density.

Correct answer: A

Rationale: Raloxifene decreases bone resorption, which helps to maintain or increase bone density, making it effective in the prevention and treatment of osteoporosis.

2. What causes secondary brain injury after head trauma?

• A. Brain injury resulting from the body’s response to tissue damage
• B. Brain injury resulting from initial trauma
• C. Injury as a result of medical therapy
• D. Focal areas of bleeding

Correct answer: A

Rationale: The correct answer is A. Secondary brain injury occurs due to the body's response to the initial trauma, which can worsen the effects of the primary injury. This response includes processes like inflammation, increased intracranial pressure, and reduced oxygen delivery to tissues. Choice B is incorrect because it refers to the primary trauma itself, not the secondary injury. Choice C is incorrect as it relates to injury caused by medical interventions rather than the body's response. Choice D is incorrect as it specifically mentions focal areas of bleeding, which is a consequence of trauma rather than the cause of secondary brain injury.

3. Inflammatory exudates are a combination of several types. Which of the following exudates is composed of a large accumulation of leukocytes?

• A. Serous
• B. Purulent
• C. Fibrinous
• D. Hemorrhagic

Correct answer: B

Rationale: The correct answer is B: Purulent. Purulent exudates, or pus, consist primarily of leukocytes and dead cells, indicating a bacterial infection. Serous exudates contain a thin, watery fluid with few leukocytes. Fibrinous exudates are rich in fibrin and are commonly seen in severe inflammation. Hemorrhagic exudates contain red blood cells due to blood vessel damage.

4. What laboratory tests should the nurse monitor regularly when a male patient is receiving androgen therapy?

• A. Monitor liver function tests regularly.
• B. Monitor renal function tests regularly.
• C. Monitor blood glucose levels regularly.
• D. Monitor complete blood count (CBC) regularly.

Correct answer: A

Rationale: The correct answer is to monitor liver function tests regularly when a male patient is receiving androgen therapy. Androgen therapy can impact liver function, making it crucial to monitor liver function tests to assess any potential adverse effects on the liver. Renal function tests (choice B) are not typically affected by androgen therapy and do not need specific monitoring for this treatment. Blood glucose levels (choice C) are more relevant in conditions like diabetes or with medications affecting blood sugar, not typically in androgen therapy. Complete blood count (CBC) (choice D) is not directly impacted by androgen therapy and is not a priority for monitoring in this context.

5. When assessing a 7-year-old child's pain after an emergency appendectomy, what is the most appropriate tool for the nurse to use?

• A. Use a visual analog scale (VAS) to assess the pain.
• B. Ask the child to rate their pain on a scale of 0 to 10.
• C. Use the Wong-Baker FACES scale to assess the pain.
• D. Ask the parents to describe the child's pain behavior.

Correct answer: C

Rationale: The correct answer is to use the Wong-Baker FACES scale to assess the child's pain. This scale is specifically designed for children and uses facial expressions of varying intensities to help them communicate their pain levels effectively. Choices A and B may not be as suitable for a young child who may have difficulty understanding or using a numerical scale. Choice D involving parents may not provide an accurate reflection of the child's pain experience, as it is essential to assess the child's self-reporting.
