Virtual ATI Pharmacology Assessment Questions
Question 1 of 5
Which of the following is NOT a site for drug metabolism:
Correct Answer: D
Rationale: The placenta is not a site for drug metabolism. Drug metabolism primarily occurs in the liver, gastrointestinal tract (GIT), skin, and kidney. The placenta serves as a barrier between the mother and fetus and is involved in nutrient and waste exchange but does not play a significant role in drug metabolism processes.
Question 2 of 5
The client receives beclomethasone (Beconase) intranasally as treatment for allergic rhinitis. He asks the nurse if this drug is safe because it is a glucocorticoid. What is the best response by the nurse?
Correct Answer: A
Rationale: Beclomethasone's low systemic absorption minimizes serious effects , reassuring its safety for rhinitis. Swallowing , duration , and dosing aren't primary concerns. A aligns with its safety profile, making it the best response.
Question 3 of 5
Atropine:
Correct Answer: A
Rationale: Atropine, a muscarinic antagonist, causes bronchodilation by relaxing bronchial smooth muscle, a true statement used in asthma or COPD. It produces mydriasis (pupil dilation), not miosis (constriction), making that false, as it blocks parasympathetic tone. It's highly lipid-soluble, crossing the blood-brain barrier, so that's false. It doesn't block acetylcholine (ACh) reuptake (there's no such mechanism) but competitively inhibits muscarinic receptors, so that's incorrect. It reduces, not increases, salivary secretions. Bronchodilation is a primary therapeutic effect, reflecting atropine's anticholinergic action, critical for respiratory applications and distinguishing it from sympathomimetics.
Question 4 of 5
A client with osteoporosis is prescribed alendronate (Fosamax). Which instruction should the nurse include?
Correct Answer: A
Rationale: Alendronate, a bisphosphonate, treats osteoporosis but risks esophageal irritation. Taking it with water and staying upright prevents reflux, ensuring safety and absorption. With meals reduces uptake via calcium binding. Crushing increases irritation risk. Bedtime heightens reflux. This instruction aligns with alendronate's administration guidelines, critical in osteoporosis where adherence prevents fractures, making A the key teaching point.
Question 5 of 5
A patient wants to take garlic tablets to improve his cholesterol levels. Which condition would be a contraindication?
Correct Answer: D
Rationale: Taking garlic tablets can potentially increase the risk of bleeding during surgery due to its blood-thinning properties. This can interfere with the body's ability to clot blood properly during and after surgery, leading to excessive bleeding and complications. Therefore, scheduled surgery is a contraindication for taking garlic tablets. It is essential to inform healthcare providers about any supplements being taken before undergoing surgery to ensure safety and prevent adverse effects.
