1. A male patient is concerned about the risk of prostate cancer while receiving finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse explain about this risk?

A. Finasteride has been shown to lower the risk of developing prostate cancer.
B. Finasteride has no effect on the risk of developing prostate cancer.
C. Finasteride may increase the risk of developing prostate cancer, so regular screening is important.
D. Finasteride does not affect the risk of prostate cancer, so regular screening is unnecessary.

Correct answer: A

Rationale: The correct answer is A. Finasteride has been shown to lower the risk of developing prostate cancer. Studies have demonstrated that finasteride can reduce the incidence of prostate cancer. However, it is still recommended to have regular screening to monitor for any potential issues. Choice B is incorrect as finasteride has shown to have a positive effect on reducing prostate cancer risk. Choice C is inaccurate because finasteride decreases, not increases, the risk of prostate cancer. Choice D is incorrect as regular screening is still necessary despite the risk reduction associated with finasteride.

2. Which of the following hormones helps to raise the blood sugar level to help maintain homeostasis?

A. Antidiuretic hormone (ADH)
B. Insulin
C. Glucagon
D. Thyroxine

Correct answer: C

Rationale: The correct answer is C, Glucagon. Glucagon helps raise blood sugar levels by stimulating the liver to release stored glucose into the bloodstream, thus aiding in maintaining homeostasis. Antidiuretic hormone (ADH), choice A, functions in regulating water balance in the body, not blood sugar levels. Insulin, choice B, lowers blood sugar levels by facilitating glucose uptake by cells. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism and has no direct effect on blood sugar levels.

3. How often should a patient be administered a tetanus toxoid?

A. Every year
B. Every 10 years
C. Every 2 years
D. Every 5 years

Correct answer: B

Rationale: Tetanus toxoid should be administered every 10 years to ensure continued protection against tetanus infection. The correct answer is 'Every 10 years.' Choice A ('Every year') is incorrect as the frequency is too frequent. Choice C ('Every 2 years') is incorrect as it is too frequent for tetanus toxoid administration. Choice D ('Every 5 years') is incorrect as it does not align with the recommended interval for tetanus toxoid booster doses.

4. Which of the following statements describes an active cellular membrane exchange process?

A. Sodium moving out of cells and potassium moving into cells
B. The movement of water from an area of low solute concentration to an area of high solute concentration
C. The movement of insulin using a protein to travel across the cell membrane
D. Oxygen moving across the pulmonary capillaries to an area of high carbon dioxide

Correct answer: A

Rationale: The correct answer is A. In active transport, energy is expended to move substances against their concentration gradient. Sodium moving out of cells and potassium moving into cells is an example of active transport because it requires energy to pump these ions across the cell membrane against their concentration gradients. Choices B, C, and D describe passive processes where substances move along their concentration gradients without the input of energy.

5. 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.
