Nursing Elites

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

• A. It stimulates the formation of new bone.
• B. It decreases bone resorption and increases bone density.
• C. It increases calcium absorption in the intestines.
• D. It increases the excretion of calcium through the kidneys.

Correct answer: B

Rationale: The correct answer is B. Raloxifene works by decreasing bone resorption and increasing bone density, which helps in the prevention and treatment of osteoporosis. Choice A is incorrect as raloxifene does not directly stimulate the formation of new bone. Choice C is incorrect because raloxifene does not primarily affect calcium absorption in the intestines. Choice D is incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

2. Which of the following is a characteristic of disseminated intravascular coagulation (DIC)?

• A. Simultaneous stroke and heart attack
• B. Simultaneous clotting and bleeding
• C. Simultaneous clotting and insulin release
• D. Simultaneous bleeding and vomiting

Correct answer: B

Rationale: Disseminated intravascular coagulation (DIC) is characterized by simultaneous clotting and bleeding throughout the body. This imbalance in the body's clotting system leads to the formation of blood clots in small blood vessels, which can consume clotting factors and platelets, ultimately leading to excessive bleeding. Choices A, C, and D are incorrect because they do not describe the characteristic feature of DIC, which involves both clotting and bleeding.

3. An experiment is designed to determine specific cell types involved in cell-mediated immune response. The experimenter is interested in finding cells that attack cells that have specific antigens. Which cells should be isolated?

• A. Lymphokine-producing cells
• B. Cytotoxic T cells
• C. Helper T cells
• D. Macrophages

Correct answer: B

Rationale: Cytotoxic T cells are the key players in cell-mediated immunity as they directly attack cells displaying specific antigens. Lymphokine-producing cells (Choice A) are involved in cytokine production, while Helper T cells (Choice C) assist in activating other immune cells. Macrophages (Choice D) are phagocytic cells that engulf and digest pathogens, but they are not the primary cells responsible for directly attacking cells with specific antigens in cell-mediated immunity.

4. Which of the following nonpharmacologic treatments is most likely to be a useful and appropriate supplement to pharmacologic analgesia at this point?

• A. Cognitive-behavioral therapy
• B. Cold and heat application
• C. Therapeutic ultrasound
• D. Biofeedback

Correct answer: B

Rationale: The correct answer is B: Cold and heat application. Cold and heat application are commonly used nonpharmacologic methods for managing pain and can complement pharmacologic treatments. Cold packs can help reduce inflammation and numb localized areas, while heat application can increase blood flow and relax muscles. Cognitive-behavioral therapy (A) focuses on changing negative thought patterns and behaviors to manage pain but may not directly supplement pharmacologic analgesia. Therapeutic ultrasound (C) uses sound waves to generate heat within body tissues, which can be therapeutic, but it may not be as directly complementary to pharmacologic analgesia as cold and heat application. Biofeedback (D) involves using electronic devices to help individuals control physiological processes, but its direct role as a supplement to pharmacologic analgesia may be less pronounced compared to cold and heat application.

5. If the client's dorsal columns are not functioning, the nurse will observe which response during neuro testing, where the nurse asks the client to close his eyes and then proceeds to touch corresponding parts of the body on each side simultaneously with two sharp points?

• A. The client will not be able to distinguish between the two points.
• B. The client will feel only one point of contact.
• C. The client will accurately identify both points.
• D. The client will report no sensation in the touched areas.

Correct answer: A

Rationale: If the client's dorsal columns are not functioning, the ability to distinguish between two closely spaced points is impaired. This results in the client not being able to differentiate between the two points when touched simultaneously. Choice B is incorrect because the client feeling only one point suggests an intact dorsal column function. Choice C is incorrect as accurately identifying both points indicates normal discrimination ability. Choice D is incorrect as reporting no sensation does not correspond to the specific impairment related to dorsal column dysfunction.
