Virtual ATI Pharmacology Assessment Questions
Question 1 of 5
The physician prescribes fluticasone (Flonase) for the client. The nurse would hold the drug and contact the physician with which assessment finding?
Correct Answer: B
Rationale: Fluticasone, an intranasal corticosteroid, is Category C, meaning fetal risks aren't fully known, so pregnancy prompts holding the drug and consulting the physician to weigh benefits versus potential harm. Diabetes or hypertension aren't contraindications; systemic effects are minimal with nasal use. Glaucoma might concern intraocular pressure with prolonged steroid use, but it's not an immediate hold reason. Pregnancy requires caution due to unknown teratogenic effects, making choice B the nurse's priority to ensure fetal safety and align with prescribing guidelines.
Question 2 of 5
When administering Phenytoin you should monitor?
Correct Answer: D
Rationale: When administering Phenytoin, it is essential to monitor all of the above: behavior, therapeutic blood levels, and for the development of Steven Johnson syndrome.
Question 3 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.
Question 4 of 5
A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?
Correct Answer: D
Rationale: St. John's wort is an herbal supplement that can interact with many medications, including venlafaxine (Effexor). When taken together, it can decrease the effectiveness of venlafaxine by increasing its metabolism, potentially leading to reduced therapeutic effects. This interaction can also increase the risk of side effects or adverse reactions.
Therefore, the nurse should be concerned about the ingestion of St. John's wort when a patient is taking venlafaxine to ensure proper medication management and effectiveness. It is important for patients to inform healthcare providers about all supplements they are taking to prevent harmful interactions.
Question 5 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.
