Question 1 of 5
The drug of choice for syphilis treatment is:
Correct Answer: B
Rationale: The correct answer is B: Penicillin. Penicillin is the drug of choice for syphilis treatment due to its effectiveness in killing the bacteria responsible for syphilis, Treponema pallidum. It is the most recommended treatment by healthcare professionals and is highly effective at curing syphilis at all stages. Gentamycin (A) is not used for syphilis treatment. Chloramphenicol (C) is not effective against Treponema pallidum. Doxycycline (D) is an alternative treatment for syphilis but is not as effective as penicillin, especially in later stages of the disease.
Question 2 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 3 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.
