Question 1 of 5
Lincozamides have the following unwanted effect:
Correct Answer: C
Rationale: The correct answer is C: Pseudomembranous colitis. Lincozamides, like clindamycin, can disrupt the normal gut flora, leading to overgrowth of Clostridium difficile and causing pseudomembranous colitis. This condition is characterized by severe diarrhea, abdominal pain, and potentially life-threatening complications. Nephrotoxicity (A) is not a common side effect of lincozamides. Cancerogenity (B) is not associated with lincozamides. Irritation of respiratory organs (D) is not a typical adverse effect of this drug class.
Question 2 of 5
Tick the unwanted effects of intravenous acyclovir infusion:
Correct Answer: A
Rationale: The correct answer is A because intravenous acyclovir can cause renal insufficiency due to its nephrotoxic effects. Tremors and delirium are not typically associated with acyclovir. Choice B includes common side effects like rash, diarrhea, and nausea that are not considered unwanted effects. Choice C includes neuropathy and abdominal pain, which are not common unwanted effects of acyclovir infusion. Choice D includes anemia, neutropenia, nausea, and insomnia, which are not typically associated with acyclovir infusion.
Question 3 of 5
In this patient, digoxin most likely decreased which of the following cardiovascular parameters?
Correct Answer: A
Rationale: The correct answer is A: Stroke volume. Digoxin increases myocardial contractility, leading to more forceful contractions and improved cardiac output. This increase in contractility results in a greater ejection fraction and subsequently an increased stroke volume. End-systolic and end-diastolic volumes are not directly affected by digoxin. Systolic pressure may increase due to enhanced contractility, but the primary effect is on stroke volume.
Question 4 of 5
Which of the following drugs given chronically would be most likely to contribute to a decreased risk of further stroke in the patient?
Correct Answer: C
Rationale: The correct answer is C: Lovastatin. Lovastatin is a statin drug that helps lower cholesterol levels, reducing the risk of atherosclerosis and subsequent stroke. It has been shown to decrease the risk of future stroke events. Isosorbide mononitrate (A) is a vasodilator used for angina, not stroke prevention. Furosemide (B) is a diuretic used for heart failure and hypertension, not for stroke prevention. Esmolol (D) is a beta-blocker used for heart rate control, not for stroke prevention.
Question 5 of 5
A 54-year-old woman with severe hypercholesterolemia is to be treated with a combination of niacin and atorvastatin. With this drug combination, it is important that the patient be monitored closely for signs of
