ATI Pharmacology Practice B Questions
Question 1 of 5
A 53-year-old man with chronic neuropathic back pain and depression is managed with amitriptyline. He has recently complained of urinary frequency and was given a prescription for Ditropan. He now complains of acute abdominal pain and is unable to pass flatus or bowel movement. What is the most likely explanation of this finding?
Correct Answer: C
Rationale: Amitriptyline and Ditropan (oxybutynin), both anticholinergics, risk paralytic ileus , stopping GI motility, causing pain and obstruction. Hepatitis , pancreatitis , overdose , and normalcy (E) don't fit. Combined anticholinergic effects explain this acute issue.
Question 2 of 5
The physician prescribes fluticasone (Flonase) for the client. The nurse would hold the drug and contact the physician with which assessment finding?
Correct Answer: B
Rationale: Fluticasone, Category C, requires caution in pregnancy , prompting physician consultation due to fetal risk uncertainty. Diabetes , glaucoma , and hypertension aren't immediate holds. B ensures safety, making it the key finding.
Question 3 of 5
The client takes a bisphosphonate for osteoporosis. Which assessment is best in determining the effectiveness of the medication?
Correct Answer: C
Rationale: Bisphosphonates (e.g., alendronate) halt bone loss-bone density scans measure improvement, per efficacy standard. Calcium levels don't reflect bone strength. Fractures or pain absence helps but isn't direct-density shows progress, per treatment.
Question 4 of 5
The nurse is giving medications to a patient in heart failure. The intravenous route is chosen instead of the intramuscular route. The nurse knows that the factor that most influences the decision about which route to use is the patient's
Correct Answer: D
Rationale: In patients with heart failure, diminished circulation is a significant concern. The intravenous (IV) route is preferred over the intramuscular (IM) route because it ensures rapid and reliable drug delivery, especially in patients with compromised cardiac output. IM injections rely on adequate blood flow for absorption, which may be impaired in heart failure due to poor circulation. Altered biliary function, increased glomerular filtration, and reduced liver metabolism are less relevant to the choice of administration route in this context. Therefore, diminished circulation is the primary factor influencing the decision to use the IV route.
Question 5 of 5
Oral decongestants differ from intranasal decongestants in that oral decongestants
Correct Answer: B
Rationale: Oral decongestants (e.g., pseudoephedrine) act systemically, vasoconstricting vessels beyond the nose, causing effects like hypertension , unlike intranasal decongestants (e.g., oxymetazoline), which are localized but risk rebound congestion. Oral efficacy isn't inherently superior; it's slower. Rebound is nasal-specific. High efficacy is vague. Choice B highlights systemic impact, a key distinction nurses must recognize for safe administration.
