Nursing Elites

1. Pain in the lower extremities due to peripheral artery disease usually worsens:

• A. with rest because blood flow increases.
• B. with elevation of the extremity because blood is diverted away.
• C. when the leg is in a dependent position because blood pools.
• D. when the leg is touched or massaged because cytokines are released.

Correct answer: B

Rationale: In peripheral artery disease, pain in the lower extremities worsens with the elevation of the extremity because it diverts blood flow away from the affected area, exacerbating the pain. Choices A, C, and D are incorrect. Resting doesn't increase blood flow, a dependent position doesn't lead to blood pooling in this context, and pain worsening due to touch or massage is not a typical feature of peripheral artery disease.

2. A woman of childbearing age is diagnosed with breast cancer. She is currently taking hormonal contraceptives. What information should the woman be given regarding the hormonal contraceptives?

• A. The hormonal contraceptives do not affect the course of the disease.
• B. The hormonal contraceptives will stimulate uterine bleeding.
• C. The hormonal contraceptives will impair uterine bleeding.
• D. The hormonal contraceptives will stimulate tumor growth.

Correct answer: A

Rationale: The correct answer is A. Hormonal contraceptives should be discontinued in women diagnosed with breast cancer because they can potentially stimulate cancer growth. Choice B is incorrect as hormonal contraceptives do not stimulate uterine bleeding. Choice C is also incorrect as hormonal contraceptives typically do not impair uterine bleeding. Choice D is incorrect because hormonal contraceptives are not meant to stimulate tumor growth.

3. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the administration of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Discontinue the medication if side effects occur.
• C. Take the medication with food to prevent gastrointestinal upset.
• D. Apply the medication once a week.

Correct answer: A

Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.

4. A patient is to be administered an immunization. The serum contains aluminum phosphate. What route is most appropriate to administer this immunization?

• A. Intramuscularly
• B. Subcutaneously
• C. Intravenously
• D. Orally

Correct answer: A

Rationale: The most appropriate route to administer an immunization containing aluminum phosphate is intramuscularly. Aluminum phosphate is commonly used as an adjuvant in vaccines to enhance the immune response. Intramuscular administration allows for the vaccine to be delivered into the muscle tissue, where it can be effectively absorbed by the body's immune cells. Subcutaneous administration is not ideal for vaccines containing aluminum phosphate, as it may not elicit the desired immune response. Intravenous administration is typically reserved for specific medications or situations that require rapid absorption into the bloodstream. Oral administration is not suitable for vaccines containing aluminum phosphate as they would be degraded in the gastrointestinal tract.

5. How are antibodies produced?

• A. B cells
• B. T cells
• C. Helper cells
• D. Memory cells

Correct answer: A

Rationale: Antibodies are produced by B cells. B cells are specialized white blood cells that generate antibodies as part of the immune response. B cells differentiate into plasma cells that secrete antibodies. T cells play a role in cell-mediated immunity, not antibody production. Helper cells, or helper T cells, assist in activating B cells but do not directly produce antibodies. Memory cells store information about previous infections but do not actively produce antibodies.
