Correct Answer: A
Rationale: Patients with peptic ulcers should stop taking NSAIDs. NSAIDs, which stands for nonsteroidal anti-inflammatory drugs, can worsen peptic ulcers by increasing the risk of gastrointestinal bleeding and ulcer formation. NSAIDs work by inhibiting prostaglandin synthesis, which can lead to a decrease in the protective mucus production in the stomach lining, allowing gastric acid to damage the mucosa and exacerbate peptic ulcers. Therefore, it is crucial for patients with peptic ulcers to avoid NSAIDs to prevent further damage to the gastrointestinal tract.
Question 2 of 5
Which of the following is an action of the drug Metformin?
Correct Answer: A
Rationale: Metformin is a commonly prescribed medication for the management of type 2 diabetes. One of the primary mechanisms of action of Metformin is to decrease hepatic glucose production. It works by inhibiting gluconeogenesis, which is the process by which the liver produces glucose. By reducing glucose production in the liver, Metformin helps to lower blood sugar levels and improve insulin sensitivity. This action helps to control hyperglycemia in patients with diabetes. The other options provided do not describe the mechanism of action of Metformin, making them incorrect choices.
Question 3 of 5
What is levothyroxine's pharmacologic classification?
Correct Answer: A
Rationale: Levothyroxine belongs to the pharmacologic classification of thyroid preparations. It is a synthetic form of the thyroid hormone thyroxine (T4) and is used to treat hypothyroidism by supplementing or replacing the body's own thyroid hormone. Levothyroxine works to normalize thyroid hormone levels in the body and help regulate metabolism. It is not a metabolic inhibitor, analgesic, or loop diuretic.
Question 4 of 5
What is the pharmacologic classification of Amlodipine
Correct Answer: D
Rationale: Amlodipine belongs to the pharmacologic class of calcium channel blockers. It works by inhibiting the influx of calcium ions into smooth muscle cells, leading to vasodilation and lower blood pressure. This medication is commonly used to treat hypertension (high blood pressure) and certain types of angina (chest pain). It is not a beta blocker, 5-HT3 antagonist, or nonopioid analgesic.
Question 5 of 5
The ability of epinephrine to cause hyperglycemia is due to;
Correct Answer: C
Rationale: The ability of epinephrine to cause hyperglycemia is primarily due to its effect on alpha adrenoreceptors in the pancreatic islets of Langerhans. Epinephrine, acting through these alpha adrenoreceptors, inhibits the release of insulin from beta cells in response to elevated blood glucose levels. This results in decreased uptake of glucose by cells, leading to increased blood glucose levels, ultimately causing hyperglycemia. Other effects of epinephrine, such as vasoconstriction and increased heart rate, also contribute to the overall stress response, but the inhibition of insulin release through alpha adrenoreceptors is the main mechanism responsible for its hyperglycemic effects.
