ATI RN Pharmacology 2023 Questions
Question 1 of 5
The nurse will monitor for myopathy (muscle pain) when a patient is taking which class of antilipemic drugs?
Correct Answer: B
Rationale: HMG-CoA reductase inhibitors, also known as statins, are a class of antilipemic drugs commonly prescribed to lower cholesterol levels. One side effect associated with statin use is myopathy, which manifests as muscle pain, tenderness, or weakness. In severe cases, myopathy can progress to rhabdomyolysis, a condition characterized by muscle breakdown and release of muscle fiber contents into the blood, potentially leading to kidney damage. It is essential for healthcare providers, such as nurses, to monitor patients on statin therapy for signs and symptoms of myopathy to intervene promptly if necessary. Niacin, fibric acid derivatives, and bile acid sequestrants are not typically associated with myopathy as a common side effect.
Question 2 of 5
The nurse assumes care of a patient in the post-anesthesia care unit (PACU). The patient had abdominal surgery and is receiving intravenous morphine sulfate for pain. The patient is asleep and has not voided since prior to surgery. The nurse assesses a respiratory rate of 10 breaths per minute and notes hypoactive bowel sounds. The nurse will contact the surgeon primarily to report which condition?
Correct Answer: B
Rationale: The primary concern in this scenario is respiratory depression. The patient receiving intravenous morphine sulfate with a respiratory rate of 10 breaths per minute indicates hypoventilation, which can progress to respiratory failure. This poses a critical risk to the patient's safety and requires immediate intervention to prevent further complications, such as respiratory arrest. Contacting the surgeon to report this condition is essential for prompt assessment and appropriate management. While paralytic ileus, somnolence, and urinary retention are also potential concerns, respiratory depression takes precedence due to its life-threatening nature.
Question 3 of 5
A patient looks up the drug he is taking in a drug guide. The patient asks the nurse why the physician prescribed a medication that has a lethal dose measure. What is the best response by the nurse?
Correct Answer: B
Rationale: Lethal dose (e.g., LD50) from research guides safe dosing by showing toxicity thresholds, reassuring the patient it informs, not dictates, prescription. It's not just research trivia-doctors use it indirectly. Side effect watching doesn't explain it. Deferring to the doctor avoids education. Research value ties to safety, clarifying its relevance.
Question 4 of 5
The nurse administers IV furosemide (Lasix) to a client with heart failure. Which finding indicates a therapeutic effect?
Correct Answer: A
Rationale: Furosemide reduces fluid overload in heart failure by diuresis, decreasing edema , a direct therapeutic sign. BP may drop, not rise. Heart rate isn't primary'preload reduction matters. Thirst is a side effect. Edema reduction aligns with furosemide's action, critical in heart failure where congestion drives symptoms, making A the key finding.
Question 5 of 5
A 17-year-old man presents to the emergency department with a persistent cough and nasal congestion. He has been taking various prescription cough and cold medicines but did not know their names. A urine drug screen is positive for amphetamines. When confronted with this information, he vehemently denies amphetamine use. What is the best explanation?
Correct Answer: B
Rationale: Positive amphetamine screen with cough/cold medicine use suggests a false positive from ephedrine . Ephedrine, in decongestants, cross-reacts with amphetamine assays. Codeine and marijuana don't. Lying or sample mix-up (E) are less likely given his denial and context. This common false positive explains the discrepancy.
