Question 1 of 5
What is the antidote for Heparin?
Correct Answer: B
Rationale: Protamine is the antidote for Heparin. Heparin is an anticoagulant medication that prevents the formation of blood clots. In case of an overdose of Heparin or if there is a need to reverse its effects quickly (such as during surgery), Protamine is administered as the specific antidote. Protamine works by binding to Heparin and neutralizing its anticoagulant effects. Therefore, Protamine is the appropriate antidote to counteract the effects of Heparin.
Question 2 of 5
The drug Ondansetron action is?
Correct Answer: C
Rationale: Ondansetron is a medication commonly used to prevent nausea and vomiting, particularly in patients receiving chemotherapy or undergoing surgery. Its mechanism of action involves blocking the effects of serotonin, specifically by antagonizing serotonin 5-HT3 receptors in the chemoreceptor trigger zone of the brain and the gastrointestinal tract. By inhibiting serotonin signaling, ondansetron helps to alleviate nausea and vomiting in affected individuals. This action is distinct from the other options provided, making option C the correct answer for the drug Ondansetron.
Question 3 of 5
Drug action that increase body activity
Correct Answer: A
Rationale: Stimulants are drugs that increase the body's activity levels. They work on the central nervous system to enhance alertness, attention, and energy. Examples of stimulants include caffeine, amphetamines, and nicotine. Stimulants can increase heart rate, blood pressure, and metabolism, leading to heightened physical and mental activity.

Question 5 of 5
If a bacteria were susceptible to both penicillin and erythromycin, then it would not be appropriate to treat the patients with both antibiotics at the same time because:
Correct Answer: A
Rationale: Penicillin is inactivated by erythromycin. Penicillin is a beta-lactam antibiotic which acts by inhibiting cell wall synthesis in bacteria. However, erythromycin is a macrolide antibiotic which can inactivate beta-lactam antibiotics like penicillin. When given together, erythromycin can inactivate penicillin, reducing its efficacy and potentially leading to treatment failure. Therefore, it is not appropriate to use both penicillin and erythromycin simultaneously to treat a bacterial infection.
