ATI N211 Pharmacology Exam Questions
Extract:
Question 1 of 5
A nurse is caring for a 2-year-old child who has seizures and is receiving phenytoin in suspension form. Which of the following actions should the nurse take before administering each dose?
Correct Answer: A
Rationale: Shaking the phenytoin suspension ensures proper mixing for accurate dosing. Mouth care, blood pressure checks, and fasting are not required.
Question 2 of 5
A nurse is caring for an adolescent client who is receiving carbamazepine for partial seizure disorder. Which of the following statements by the client's parent is the nurse's priority?
Correct Answer: D
Rationale: New bruises can indicate a serious adverse effect, such as bone marrow suppression leading to thrombocytopenia, which requires immediate attention. Naps, nausea, and dry mouth are less urgent concerns.
Question 3 of 5
A nurse is teaching a client who has a new prescription for lithium to treat bipolar disorder. The nurse should instruct the client to ensure an adequate intake of which of the following dietary elements?
Correct Answer: C
Rationale: Adequate sodium intake is crucial, as low sodium increases lithium toxicity, and high sodium reduces effectiveness. Potassium, vitamin C, and vitamin K are not directly related.
Question 4 of 5
A hospice nurse is caring for a client who has terminal cancer and takes PO morphine for pain relief. The client reports that he had to increase the dose of morphine this week to obtain pain relief. Which of the following scenarios should the nurse document as the explanation for this situation?
Correct Answer: A
Rationale:
Tolerance to opioids like morphine requires higher doses over time for the same pain relief, common in terminal cancer pain management. Confusion, improper use, or addiction are less likely explanations.
Question 5 of 5
A nurse is reviewing a client's prescription for 1,000 mL of 5% dextrose in water IV to infuse over 8 hr. At 1400, the nurse observes that there is 500 mL of solution remaining in the client's current IV bag. At what time should the nurse administer the next bag of IV solution?
Correct Answer: D
Rationale: Infusion rate: 1000 mL ÷ 8 hr = 125 mL/hr. At 1400, 500 mL remains (4 hr at 125 mL/hr), so the bag finishes at 1800, when the next bag should be administered.
