Virtual ATI Pharmacology Assessment Questions
Question 1 of 5
The client receives hydroxychloroquine sulfate (Plaquenil). Which test does the nurse tell the client should be done on a regular basis?
Correct Answer: B
Rationale: Hydroxychloroquine risks retinal damage-regular eye exams (e.g., yearly) detect it early, per safety. Potassium, glucose, and BP aren't directly tied-retinopathy is key. Exams monitor vision, per protocol.
Question 2 of 5
The nurse notes in the patient™s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?
Correct Answer: C
Rationale: The primary goal of anticoagulant therapy is to prevent the formation of blood clots or thrombi. Anticoagulants work by inhibiting the clotting process in the blood, thereby reducing the risk of clot formation in the blood vessels. This helps to prevent conditions such as deep vein thrombosis, pulmonary embolism, stroke, and other thromboembolic events. Anticoagulants do not dissolve existing clots (thrombus), they work to prevent new clots from forming. So, the main objective of starting anticoagulant therapy in a patient is to prevent the development of thrombi.
Question 3 of 5
Which method would the nurse use to administer medications to school-age children?
Correct Answer: B
Rationale: School-age kids (6-12) grasp brief explanations-e.g., 'This helps your cough'-fitting their cognitive level, easing administration. Full decision-making exceeds maturity. Holding down distresses, not needed. Lengthy talks lose attention. Brief explanation leverages development, ensuring cooperation.
Question 4 of 5
Which of the following drugs is contraindicated if there is a history of acute porphyria?
Correct Answer: C
Rationale: Acute porphyria involves heme synthesis defects, triggered by drugs inducing hepatic enzymes (e.g., CYP450). Quinine, used in malaria, isn't a major porphyria trigger. Atenolol, a beta-blocker, is porphyrin-safe, with minimal enzyme induction. Oral contraceptives, containing estrogens/progestins, induce ALA synthase, exacerbating acute porphyria, making them contraindicated. Heparin and amoxicillin don't significantly affect porphyrin metabolism. The contraceptive link reflects hormonal exacerbation of porphyric attacks, critical for safe prescribing in this rare condition.
Question 5 of 5
An elderly woman took a prescription medicine to help her to sleep; however, she felt restless all night and did not sleep at all. The nurse recognizes that this woman has experienced which type of reaction or effect?
Correct Answer: B
Rationale: An idiosyncratic reaction is an unusual or unexpected response to a medication that is not related to the drug's known pharmacological effects. In this case, the elderly woman experienced restlessness instead of sedation, which is contrary to the expected effect of a sleep aid. Idiosyncratic reactions are unpredictable and can vary widely among individuals. Allergic reactions involve the immune system, mutagenic effects involve genetic changes, and synergistic effects involve interactions between multiple drugs. Since the woman's response was unexpected and not consistent with the drug's intended effect, it is classified as an idiosyncratic reaction.
