Question 1 of 5
An 18-year-old man is brought to the emergency department by a friend after smoking crack cocaine because he was 'acting funny.' His temperature is 38°C (100.4°F), pulse is 110 beats/minute, and he appears agitated. Which of the following is an effect of cocaine intoxication?
Correct Answer: D
Rationale: Cocaine intoxication (agitation, tachycardia, fever) causes vasoconstriction , via sympathetic stimulation, raising BP and temperature. Hypercoagulability occurs but isn't primary. Hypocoagulability and hypothermia oppose effects. Vasodilation (E) is wrong. This drives his symptoms.
Question 2 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 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
The nurse provides care for elders in an assisted living facility. What does the nurse assess as a primary contributing factor for drug toxicity in the elderly?
Correct Answer: B
Rationale: Dehydration, common in elders from reduced thirst, lowers drug clearance (e.g., renal function drops), risking toxicity-key in pharmacokinetics. Alcohol abuse varies, not primary. Constipation affects excretion less than fluid status. Stomach acid decreases, not increases, with age. Dehydration's impact on volume and clearance drives toxicity risk.
Question 5 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.
