ATI Pharmacology Exam Practice Questions
Question 1 of 5
A client calls the clinic and tells the nurse that she has missed taking several of her contraceptive pills during the current cycle. What is the best instruction for the nurse to give the client?
Correct Answer: D
Rationale: Missing several contraceptive pills compromises efficacy, requiring an alternative method for the cycle to prevent pregnancy. Testing assesses outcome, not prevention. Future methods don't address now. Fewer than three still risks failure. D ensures immediate protection, making it the best instruction.
Question 2 of 5
The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask?
Correct Answer: D
Rationale: Oxymetazoline, a nasal decongestant, can cause rebound congestion (rhinitis medicamentosa) if used beyond 3-5 days, worsening symptoms due to vascular dependence. The best assessment question is how long the client has used it, as prolonged use is the likely culprit, guiding the nurse to educate on discontinuation or seek medical advice. The bottle's age might affect potency but isn't the primary concern for worsening symptoms. Temperature checks for infection, a secondary issue here. Other inhaled medications could interact but don't directly explain rebound effects. The nurse prioritizes duration to pinpoint misuse, a common issue with topical decongestants, making choice D critical for accurate assessment and intervention.
Question 3 of 5
Patients should avoid what drink while taking Alprazolam?
Correct Answer: B
Rationale: Patients taking Alprazolam should avoid consuming grapefruit juice. Grapefruit juice can interfere with the metabolism of Alprazolam in the body, leading to increased levels of the medication in the bloodstream. This can potentiate the sedative effects of Alprazolam and increase the risk of side effects or overdose. It is best to consult with a healthcare provider or pharmacist regarding any potential interactions with grapefruit juice and medications.
Question 4 of 5
Drugs can cause adverse events in a patient. Bone marrow toxicity is one of the most frequent types of drug-induced toxicity. The most serious form of bone marrow toxicity is:
Correct Answer: A
Rationale: Aplastic anemia is the most severe form of bone marrow toxicity, characterized by pancytopenia and bone marrow failure. It can be life-threatening and requires immediate intervention. Thrombocytosis, leukocytosis, and granulocytosis are not typically associated with drug-induced bone marrow toxicity.
Question 5 of 5
The adolescent is supposed to go to the school nurse at 12:00 to receive his medication for attention-deficit hyperactivity disorder (ADHD). He often does not go for the medication. What best describes the nurse's understanding of this situation?
Correct Answer: A
Rationale: Adolescents prioritize peer image-skipping ADHD meds (e.g., Ritalin) at school likely stems from embarrassment, a developmental trait. Lack of understanding or forgetting is possible but less likely with routine. Conscious refusal needs evidence (e.g., verbal rejection). Embarrassment fits social sensitivity, guiding intervention.
