ATI Intro to Pharmacology Quizlet Questions
Question 1 of 5
The nurse is managing the care of a group of patients with schizophrenia. The patients are receiving conventional antipsychotic medications. When assessing for anticholinergic side effects, which would the nurse immediately report to the physician?
Correct Answer: D
Rationale: Conventional antipsychotics like haloperidol have anticholinergic effects, including dry mouth, constipation, and urinary retention. Urinary retention is a medical emergency if severe, risking bladder damage or infection, requiring immediate physician reporting. Acute dystonia is an extrapyramidal side effect, not anticholinergic, though urgent. Severe headache could indicate various issues but isn't a typical anticholinergic effect. Hypertension isn't directly linked to anticholinergic action (hypotension is more common). The nurse prioritizes urinary retention due to its potential for rapid complications, aligning with anticholinergic pharmacology, making choice D the most critical to report.
Question 2 of 5
The nurse enters a patient’s room to find that his heart rate is 120, his blood pressure is 70/50, and he has red blotching of his face and neck. Vancomycin is running intravenous piggyback. The nurse believes that this patient is experiencing a severe adverse effect called red man syndrome. What action will the nurse take?
Correct Answer: A
Rationale: Red man syndrome is a hypersensitivity reaction to vancomycin, characterized by flushing, rash, hypotension, and tachycardia. The nurse should immediately stop the infusion to prevent further reaction and call the health care provider for further instructions. Reducing the infusion rate may help in mild cases, but in this severe case, stopping the infusion is the priority. Encouraging fluids is not appropriate for managing this acute reaction. Stevens-Johnson syndrome is a different, more severe condition and is not indicated by these symptoms.
Question 3 of 5
A 42-year-old woman with a 1-year history of rheumatoid arthritis comes to see her primary care physician complaining of worsening symptoms. She has been taking leflunomide. IL-1 and TNF-α are two key cytokines involved in the negative sequelae of rheumatoid arthritis. Which of the following drugs is a recombinant form of an endogenous IL-1 antagonist?
Correct Answer: B
Rationale: RA involves IL-1 and TNF-α driving inflammation. The question seeks a recombinant IL-1 antagonist. Abatacept inhibits T-cell costimulation, not IL-1. Anakinra , a recombinant IL-1 receptor antagonist (IL-1Ra), blocks IL-1 signaling, matching the description. Methotrexate slows cell proliferation, not an IL-1 antagonist. Hydroxychloroquine modulates immunity differently. Rituximab (E) targets B cells. Anakinra mimics natural IL-1Ra, reducing joint damage in RA when leflunomide fails, directly countering IL-1's effects, unlike broader or unrelated mechanisms of other options.
Question 4 of 5
A client is prescribed Colchicine. After taking three doses, the client complains of nausea, vomiting, and loose bowel stools. Which of the following should the client do?
Correct Answer: B
Rationale: Nausea, vomiting, and diarrhea are signs of colchicine toxicity, which can be life-threatening. The client should stop taking the medication and notify the physician immediately. Continuing the medication or adjusting the dose without medical advice can exacerbate the toxicity. Colchicine has a narrow therapeutic index, and close monitoring is required to prevent adverse effects.
Question 5 of 5
Biperiden hydrochloride (Akineton) is added to a list of antiparkinsonian medications that an elderly client is taking. Which of the following instructions made by the nurse that needs further learning?
Correct Answer: C
Rationale: Walking in the morning for direct sunlight is unrelated to the use of biperiden hydrochloride (Akineton) and does not address its side effects or therapeutic effects. Avoiding alcohol and caffeine, managing dry mouth, and increasing fiber and fluid intake are appropriate instructions. Therefore, the statement about sunlight indicates a need for further learning.
