1. A patient is being treated with finasteride (Proscar) for benign prostatic hyperplasia (BPH). What expected outcome should the nurse include in the patient teaching?

A. The medication will cure BPH after treatment is complete.
B. The effects of the medication may take several weeks or months to become noticeable.
C. The medication may cause increased hair growth.
D. The medication may decrease libido.

Correct answer: B

Rationale: The correct answer is B. Finasteride is used to reduce the size of the prostate gland in patients with BPH, leading to decreased urinary frequency and urgency over several weeks or months. Choice A is incorrect because finasteride does not cure BPH but helps manage symptoms. Choice C is incorrect as increased hair growth is associated with another medication called minoxidil, not finasteride. Choice D is incorrect since finasteride may cause a decrease in libido as a side effect.

2. A 21-year-old male is brought to the ED following a night of partying in his fraternity. His friends found him 'asleep' and couldn't get him to respond. They cannot recall how many alcoholic beverages he drank the night before. While educating a student nurse and the man's friends, the nurse begins by explaining that alcohol is:

A. A water-soluble compound that is easily absorbed by the gastric lining of the stomach.
B. Very lipid-soluble and rapidly crosses the bloodâ€“brain barrier.
C. Able to reverse the transport of some substances to remove them from the brain.
D. Very likely to cause sedation and therefore the client just needs to sleep it off.

Correct answer: B

Rationale: The correct answer is B. Alcohol is very lipid-soluble and rapidly crosses the bloodâ€“brain barrier, leading to its effects on the central nervous system and causing symptoms like sedation and unconsciousness. Choice A is incorrect because alcohol is not water-soluble; it is lipid-soluble. Choice C is incorrect as alcohol does not reverse the transport of substances from the brain. Choice D is incorrect as sedation from alcohol is not a reason to just 'sleep it off' in cases of alcohol poisoning, which can be life-threatening and requires medical attention.

3. 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.

4. A patient with a history of osteoporosis is prescribed raloxifene (Evista). 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: 'It decreases bone resorption and increases bone density.' Raloxifene, as a selective estrogen receptor modulator (SERM), works by reducing bone resorption (breakdown) and maintaining or increasing bone density. This mechanism helps in preventing further bone loss and can even increase bone mass. Choices A, C, and D are incorrect. Raloxifene does not stimulate the formation of new bone (choice A), increase calcium absorption in the intestines (choice C), or increase the excretion of calcium through the kidneys (choice D).

5. A patient with a history of breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse include in the patient education?

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

Correct answer: A

Rationale: Tamoxifen increases the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots and the importance of seeking immediate medical attention if they occur.
