Question 1 of 5
Stress-induced cortisol hormone secretion is associated with:
Correct Answer: B
Rationale: The correct answer is B: Regulation of the stress response. Cortisol plays a crucial role in regulating the body's response to stress by modulating various physiological processes.
Choices A, C, and D are incorrect because stress-induced cortisol hormone secretion is not directly associated with increased growth hormone levels, increased thyroid-stimulating hormone, or depressed adrenal gland function.
Question 2 of 5
The nurse knows which phenomenon listed below is an accurate statement about axonal transport?
Correct Answer: B
Rationale: The correct answer is B. Axonal transport involves the movement of materials to the nerve terminal by either fast or slow components, which is essential for cell survival.
Choice A is incorrect because while anterograde and retrograde axonal transport are involved in the movement of materials, they do not specifically relate to the communication of nerve impulses between a neuron and the CNS.
Choice C is incorrect because the unidirectional nature of axonal transport does not primarily function to protect the CNS against pathogens.
Choice D is incorrect as axonal transport is responsible for the movement of various materials, not just electrical impulses.
Question 3 of 5
A patient is starting on a statin medication for hyperlipidemia. What critical instruction should the nurse provide?
Correct Answer: A
Rationale: The correct answer is A. Statins like atorvastatin should be taken at night to reduce the risk of muscle pain and other side effects. Taking the medication with a high-fat meal (choice
D) is not recommended as it can decrease the effectiveness of the medication. Alcohol consumption (choice
C) should be moderated but does not need to be completely avoided unless contraindicated. Taking the medication with breakfast (choice
B) may not be as effective as taking it at night due to the circadian rhythm of cholesterol synthesis.
Question 4 of 5
A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug. How should the nurse best respond to the patient's question?
Correct Answer: B
Rationale: The correct answer is B. Using multiple drugs in tuberculosis treatment helps prevent the development of drug-resistant TB. This approach is crucial because if the infection is not completely eradicated, the remaining bacteria may become resistant to the single drug used, making future treatments less effective.
Choice A is incorrect because the use of multiple drugs is not due to uncertainty about which drug will work, but rather to address the bacteria from different angles.
Choice C is incorrect as it misleads the patient about the reason for using multiple drugs.
Choice D is also incorrect because the primary purpose of using multiple drugs is not to speed up treatment but to ensure effectiveness and prevent resistance.
Question 5 of 5
When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?
Correct Answer: A
Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy.
Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy.
Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects.
Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.
