Question 1 of 5
Zanamivir is ordered for a patient with which disorder?
Correct Answer: C
Rationale: Zanamivir is an antiviral medication used to treat influenza, not herpes simplex virus or hepatitis B. Varicella-zoster virus is the cause of chickenpox and shingles, which are treated with other antivirals like acyclovir. This question seems to have an error, as zanamivir is not used for any of the listed conditions.
Question 2 of 5
What information will the nurse include when teaching the patients about taking beta2-blocking drugs for the treatment of angina?
Correct Answer: D
Rationale: When teaching patients about taking beta2-blocking drugs for the treatment of angina, it is important to include information about monitoring for signs of heart failure. Weight gain can be an early sign of fluid retention, which can indicate heart failure. Instructing patients to alert their healthcare provider if they experience a weight gain of 2 lb or more in 24 hours or 5 lb or more in 1 week can help in early detection and management of potential heart failure. This is crucial for the safety and well-being of the patient.
Question 3 of 5
The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?
Correct Answer: C
Rationale: Estrogen suppresses androgen production , starving androgen-dependent prostate cancer. Choice A misstates cell death. Choice B overstates testosterone elimination. Choice D misattributes nutrient blockade. C explains the hormonal mechanism accurately, making it the best response.
Question 4 of 5
While assessing a patient who is receiving intravenous digitalis, the nurse recognizes that the drug has a negative chronotropic effect. How would this drug effect be evident in the patient?
Correct Answer: B
Rationale: Digitalis has a negative chronotropic effect, meaning it slows down the heart rate. This can be evident in a patient by observing a decrease in their heart rate. Chronotropy refers to the heart rate or rhythm of the heart. Digitalis works by inhibiting the sodium-potassium pump in the heart muscle cells, leading to an increase in intracellular calcium levels. This results in a decreased heart rate and improved contractility of the heart muscle. Therefore, a decreased heart rate is the expected effect when a patient is receiving intravenous digitalis.
Question 5 of 5
What are the therapeutic and adverse effects associated with the adrenergic blocking agents related to?
Correct Answer: A
Rationale: The therapeutic and adverse effects associated with these drugs are related to their adrenergic-receptor-site specificity; that is, the ability to react with specific adrenergic receptor sites without activating them, thus preventing the typical manifestations of sympathetic nervous system (SNS) activation. By occupying the adrenergic receptor site, they prevent norepinephrine released from the nerve terminal or from the adrenal medulla from activating the receptor, thus blocking the SNS effects. The nurse should understand the mechanism of action of adrenergic blocking agents to ensure safe and effective administration.
