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

A. Medroxyprogesterone should be taken with food to prevent nausea.
B. Medroxyprogesterone can be taken intermittently when symptoms worsen.
C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels.
D. Medroxyprogesterone should be discontinued if side effects occur.

Correct answer: C

Rationale: The correct answer is C. Medroxyprogesterone should be taken at the same time each day to maintain consistent hormone levels and effectiveness. Taking it at different times can lead to hormonal fluctuations and reduced medication efficacy. Choice A is incorrect because medroxyprogesterone does not need to be taken with food to prevent nausea. Choice B is incorrect as medroxyprogesterone is typically taken continuously rather than intermittently. Choice D is incorrect because side effects should be reported to the healthcare provider for further evaluation and management, not automatically leading to discontinuation of the medication.

2. What causes atherosclerotic plaques to form initially?

A. Interruption of blood flow to the brain
B. Injury to the coronary artery endothelium
C. Administration of statin medications
D. Poor dietary modifications

Correct answer: B

Rationale: Atherosclerotic plaques form initially due to injury to the coronary artery endothelium, which triggers a cascade of events leading to plaque buildup. Choice A is incorrect because atherosclerotic plaques do not form due to an interruption of blood flow to the brain. Choice C is incorrect as statin medications are actually used to help lower cholesterol and reduce the risk of plaque formation. Choice D is incorrect as poor dietary modifications can contribute to atherosclerosis but are not the initial cause of plaque formation.

3. A 30-year-old male was diagnosed with HIV. Which of the following treatments would be most effective?

A. Reverse transcriptase inhibitors
B. Protease inhibitors
C. Entrance inhibitors
D. Highly active antiretroviral therapy

Correct answer: D

Rationale: The correct answer is D: Highly active antiretroviral therapy (HAART). HAART involves a combination of different classes of antiretroviral drugs, which can effectively suppress the HIV virus, reduce the viral load, and improve the immune function. While choices A, B, and C are also used in HIV treatment, the most effective approach is a combination therapy like HAART due to its ability to target the virus at different stages of its life cycle, reducing the risk of drug resistance and improving treatment outcomes.

4. What is the primary function of the kidneys in acid-base balance?

A. The kidneys remove hydrogen ions and retain bicarbonate ions.
B. The kidneys convert ammonia into urea, which is excreted in the urine.
C. The kidneys produce aldosterone to regulate sodium levels.
D. The kidneys secrete renin to regulate blood pressure.

Correct answer: A

Rationale: The correct answer is A. The kidneys are crucial in maintaining acid-base balance by removing hydrogen ions to decrease acidity and retaining bicarbonate ions to increase alkalinity. Choice B is incorrect because the conversion of ammonia into urea is related to nitrogen waste excretion, not acid-base balance. Choice C is incorrect as aldosterone regulates sodium levels, not acid-base balance. Choice D is also incorrect as renin is involved in regulating blood pressure, not acid-base balance.

5. What are the major mechanisms of spinal cord injuries?

A. Hypoextension, expansion, hyperflexion
B. Hyperflexion, expansion, hypometabolism
C. Hypermetabolism, compression, hyperextension
D. Hyperextension, hyperflexion, compression

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.
