ATI Pharmacology Exam Practice Questions
Question 1 of 5

Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
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
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 4 of 5
The nurse is caring for a client receiving tamoxifen (Nolvadex) for breast cancer. Which side effect should the nurse monitor for?
Correct Answer: A
Rationale: Tamoxifen, an estrogen receptor modulator, treats breast cancer but blocks estrogen in some tissues, causing hot flashes , a common menopausal-like effect. Monitoring this ensures client comfort and adherence, as it's frequent and distressing. Hair loss is more chemotherapy-related, not tamoxifen. Nausea and diarrhea occur less often and are less specific. Hot flashes align with tamoxifen's anti-estrogenic action, a key consideration in breast cancer management where long-term use is common. This focus aids in symptom management, distinguishing it from cytotoxic effects, making A the priority side effect to monitor.
