1. How can a colony-stimulating factor affect the patient's erythrocyte count?

Correct answer: A

Rationale: Colony-stimulating factors are substances that stimulate the production of blood cells in the bone marrow. Erythrocytes are red blood cells, so a colony-stimulating factor would specifically stimulate the growth of red blood cells, leading to an increase in the patient's erythrocyte count. Choice B is incorrect because colony-stimulating factors do not suppress T-cell production. Choice C is incorrect because colony-stimulating factors do not inhibit protein synthesis. Choice D is incorrect because colony-stimulating factors do not stimulate antibody production; they primarily affect the production of blood cells.

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

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.

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

Correct answer: A

Rationale: Raloxifene decreases bone resorption, which helps to maintain or increase bone density, making it effective in the prevention and treatment of osteoporosis.

4. A patient is being treated for active tuberculosis with ethambutol (Myambutol). The patient states to the nurse that he cannot identify the red and green on the traffic lights when he is driving. Based on this finding, what medical intervention is most appropriate?

Correct answer: A

Rationale: The correct answer is to assess for photosensitivity. Ethambutol can cause optic neuritis, leading to visual disturbances, including difficulty differentiating red and green colors. This is a sign of optic nerve damage and requires immediate evaluation. Discontinuing ethambutol may be necessary if optic neuritis is confirmed, but this decision should be made by a healthcare provider. Decreasing the dose of ethambutol may not address the visual changes. Administering vitamin B does not directly address the side effect caused by ethambutol.

5. Which of the following factors are known to contribute to an individual's ability to adapt to stress? (Select ONE that does not apply.)

Correct answer: A

Rationale: The correct factors that contribute to an individual's ability to adapt to stress are age, socioeconomic status, and gender. Age can influence coping mechanisms and resilience. Socioeconomic status can impact access to resources and support systems. Gender differences can also play a role in how individuals experience and manage stress. Ethnicity, while important in other contexts, is not directly mentioned in the provided rationale and is not one of the factors listed as contributing to an individual's ability to adapt to stress.
