Question 1 of 5

A patient is prescribed raloxifene (Evista) for osteoporosis. What is the primary therapeutic action of this medication?

Correct Answer: B

Rationale: The correct answer is B. Raloxifene works by decreasing bone resorption and increasing bone density, which helps in the prevention and treatment of osteoporosis. Choice A is incorrect as raloxifene does not directly stimulate the formation of new bone. Choice C is incorrect because raloxifene does not primarily affect calcium absorption in the intestines. Choice D is incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

Question 2 of 5

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?

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.

Question 3 of 5

What critical point should the nurse include in patient education regarding tamoxifen (Nolvadex) for a patient with breast cancer?

Correct Answer: A

Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism. Patients should be educated about the signs and symptoms of blood clots, such as swelling, redness, and pain in the legs. Choices B, C, and D are incorrect because tamoxifen is not associated with causing hot flashes, weight gain, fluid retention, or decreasing the risk of osteoporosis.

Question 4 of 5

A client has been admitted to the hospital with symptoms of Guillain-Barr© syndrome. Which aspect of the client's condition would require priority monitoring?

Correct Answer: B

Rationale: In Guillain-Barr© syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barr© syndrome.

Question 5 of 5

The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:

Correct Answer: C

Rationale: When GABA binds with a receptor site, it causes hyperpolarization of the local nerve membrane, making it less excitable. This hyperpolarization leads to inhibition of nerve cell activity. Choice A is incorrect because GABA is a neurotransmitter itself and does not require three chemical substances to stimulate activity between cells. Choice B is incorrect as GABA triggers inhibitory postsynaptic potentials (IPSPs), leading to hyperpolarization, not depolarization, of the postsynaptic membrane. Choice D is also incorrect as it describes a process involving cholinergic receptors and acetylcholine, which is unrelated to GABA's mechanism of action.
