Pathophysiology Final Exam

1. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What important instruction should the nurse provide about the use of this medication?

A. Take the medication with food to prevent nausea.
B. Discontinue the medication if side effects occur.
C. Take the medication at the same time each day to maintain consistent hormone levels.
D. Avoid prolonged sun exposure while taking this medication.

Correct answer: C

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels. This is crucial for the effectiveness of medroxyprogesterone acetate in treating endometriosis. Choice A is incorrect because there is no specific instruction related to food intake. Choice B is incorrect because discontinuing the medication without consulting a healthcare provider can be harmful. Choice D is unrelated to the administration of medroxyprogesterone acetate and is not a specific consideration for this medication.

2. 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.

3. What function does aldosterone serve in the body?

A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
D. Aldosterone enhances intracellular sodium production and lowers blood pressure

Correct answer: B

Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.

4. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What should the nurse emphasize during patient education?

A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be aware of the signs and symptoms of blood clots.
B. Tamoxifen may cause weight gain, so patients should monitor their diet.
C. Tamoxifen may cause hot flashes and other menopausal symptoms.
D. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.

Correct answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism, a serious side effect. Therefore, patients should be educated about the signs and symptoms of blood clots, such as swelling, pain, and redness in the legs, and advised to seek immediate medical attention if they occur. Choice B is incorrect because weight gain is not a significant side effect of tamoxifen. Choice C is incorrect because hot flashes and menopausal symptoms are common side effects of tamoxifen but are not as critical to address as venous thromboembolism. Choice D is incorrect because tamoxifen does not decrease the risk of osteoporosis; in fact, it may increase the risk of bone loss in premenopausal women.

5. Cellular swelling is:

A. Irreversible
B. Evident early in all types of cellular injury
C. Manifested by decreased intracellular sodium
D. None of the above is correct

Correct answer: B

Rationale: Cellular swelling is indeed evident early in all types of cellular injury. This occurs due to the influx of water into the cell, leading to swelling. Choice A is incorrect because cellular swelling is reversible if the injury is not severe. Choice C is incorrect because cellular swelling is not manifested by decreased intracellular sodium; in fact, it is associated with increased intracellular sodium due to water influx. Choice D is incorrect as option B is the correct statement.
