1. A patient is prescribed raloxifene (Evista) for osteoporosis. 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. 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.

2. A 69-year-old female patient has been diagnosed with malignant melanoma. The care team has collaborated with the patient and her family and agreed on a plan of care that includes administration of interferon alfa-2b. After administering interferon alfa-2b, the oncology nurse should anticipate that the patient may develop which of the following adverse effects?

A. Profound diaphoresis
B. Decreased level of consciousness
C. Flu-like symptoms
D. Cyanosis and pallor

Correct answer: C

Rationale: After the administration of interferon alfa-2b, the patient may develop flu-like symptoms as an adverse effect. Flu-like symptoms are commonly associated with interferon therapy, including fever, chills, fatigue, and muscle aches. These symptoms usually subside over time. Options A, B, and D are not typically associated with interferon alfa-2b administration. Profound diaphoresis is excessive sweating, decreased level of consciousness indicates neurological issues, and cyanosis and pallor suggest circulatory or respiratory problems, none of which are expected adverse effects of interferon alfa-2b.

3. When a client has their 'fight or flight' system activated, which below is a manifestation of that?

A. Decreased blood pressure
B. Decreased heart rate
C. Decreased respiration rate
D. Increased glucose levels

Correct answer: D

Rationale: The correct answer is D, 'Increased glucose levels.' When the 'fight or flight' system is activated, the body releases glucose to provide energy for the impending response. This increase in glucose levels helps fuel the body's reaction to the perceived threat or stressor. Choices A, B, and C are incorrect because during the 'fight or flight' response, blood pressure, heart rate, and respiration rate typically increase to prepare the body to confront or flee from the perceived danger.

4. What is the most sensitive indicator of altered brain function?

A. The ability to perform complex mathematics
B. Altered level of consciousness
C. The lack of cerebrospinal fluid production
D. Intact cranial nerve functions

Correct answer: B

Rationale: The correct answer is B: Altered level of consciousness. Changes in consciousness are the most sensitive indicator of altered brain function as they can signal underlying neurological issues. Option A, the ability to perform complex mathematics, though it involves brain function, is not as sensitive or direct an indicator as altered consciousness. Option C, the lack of cerebrospinal fluid production, is more related to conditions like hydrocephalus rather than a direct indicator of altered brain function. Option D, intact cranial nerve functions, indicate the normal functioning of peripheral nerves and are not as sensitive to changes in brain function as alterations in consciousness.

5. A client with multiple sclerosis (MS) is experiencing a relapse. Which of the following factors is most likely contributing to the relapse?

A. Taking an over-the-counter multivitamin
B. Experiencing high levels of emotional stress
C. Getting a flu shot
D. Engaging in strenuous physical activity

Correct answer: B

Rationale: Emotional stress can trigger a relapse in multiple sclerosis by exacerbating symptoms. While taking an over-the-counter multivitamin and getting a flu shot are generally safe, they are not typically known to trigger MS relapses. Engaging in strenuous physical activity, if done carefully, can actually have benefits for individuals with MS by improving strength and mobility, so it is less likely to be the cause of a relapse.
