Question 1 of 5

Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What is Heparin's antidote?
Correct Answer: A
Rationale: Protamine sulfate is the antidote for Heparin. Heparin is an anticoagulant medication that works by inhibiting clotting factors in the blood. In cases of Heparin overdose or when a patient needs to quickly reverse the effects of Heparin, Protamine sulfate is administered as an antidote. Protamine sulfate works by binding to Heparin and neutralizing its anticoagulant effects, thus helping to restore normal clotting function. It is important to use Protamine sulfate cautiously as it can cause severe reactions in some individuals, especially those with allergies to fish, as Protamine is derived from fish sperm.
Question 3 of 5
Which of the following medications works to lessen the loss of potassium a while at the same time acting as a diuretic
Correct Answer: B
Rationale: Spironolactone is a potassium-sparing diuretic, which means that it helps lessen the loss of potassium from the body while still acting as a diuretic. This medication works by blocking the actions of aldosterone, a hormone that promotes the retention of sodium and water in the body, which can lead to potassium loss. Spironolactone helps to increase potassium levels in the body, making it a suitable choice for patients who are at risk of or experiencing low potassium levels while needing diuretic therapy. Options A, C, and D are not potassium-sparing diuretics, and they do not specifically help in lessening the loss of potassium from the body.
Question 4 of 5
Basic component of a blood clot
Correct Answer: A
Rationale: Platelets are the basic component of a blood clot. When there is an injury to a blood vessel, platelets are activated and aggregate at the site to form a plug, which is the first step in the clotting process. Platelets release chemicals that further promote clot formation, eventually leading to the formation of a stable blood clot. While fibrin, thrombin, thromboxane, and ADP are also involved in the clotting process, platelets play a central role in the initial formation of a blood clot.
Question 5 of 5
Which of the following is described as the route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral drug administration is the route where the drug is placed directly into the gastrointestinal tract (GIT), such as through the mouth (oral administration) or through a feeding tube. Once administered, the drug is absorbed through the walls of the GI tract into the bloodstream for systemic distribution. This is in contrast to parenteral routes where drugs are administered by methods other than through the digestive system, such as injections, inhalation, or topical application. Intravenous (IV) administration, specifically mentioned in the question, is a type of parenteral route where drugs are injected directly into a vein for rapid and complete systemic distribution.
