Pharmacology Assessment 2 ATI Capstone Questions
Question 1 of 5
The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician?
Correct Answer: D
Rationale: Diphenhydramine, a first-generation antihistamine, has anticholinergic effects, including urinary hesitancy , due to reduced bladder contractility. This can escalate to retention, a serious issue, especially in older adults or those with prostate issues, warranting physician reporting. Sedation is expected and manageable, not typically reported unless severe. Diarrhea isn't common; constipation is more likely. Projectile vomiting suggests a different pathology, not a typical antihistamine effect. The nurse teaches reporting urinary hesitancy as it's a significant anticholinergic complication requiring intervention, making choice D the priority symptom to monitor.
Question 2 of 5
The patient is admitted to the hospital in chronic renal failure and is on several medications. What best describes the nurse's assessment of this patient?
Correct Answer: C
Rationale: Chronic renal failure impairs kidney excretion, critical for drugs cleared renally-like metformin-raising toxicity risk if doses aren't adjusted, a targeted concern. Liver compensation aids metabolism, not excretion, so effectiveness isn't assured. Toxicity from all drugs assumes universal renal clearance, too broad. Decreased effectiveness ignores accumulation risks. Assessing for renal-excreted drugs' toxicity aligns with kidney function's role, ensuring safety by checking specific drug profiles.
Question 3 of 5
Sedatives and hypnotics are drugs which act as:
Correct Answer: B
Rationale: Sedatives and hypnotics are drugs that act as depressants on the central nervous system. They slow down brain activity, leading to relaxation, drowsiness, and in higher doses, inducing sleep. These drugs are commonly used to reduce anxiety, promote sleep, or induce anesthesia. Therefore, the correct classification for sedatives and hypnotics is as depressants.
Question 4 of 5
The nurse is caring for a postoperative patient. The nurse will anticipate administering which medication to this patient to help prevent thrombus formation caused by slow venous blood flow?
Correct Answer: D
Rationale: Low-molecular-weight heparin is commonly administered to postoperative patients to help prevent thrombus formation caused by slow venous blood flow. This medication works by inhibiting the formation of blood clots. It is considered safer and more effective than unfractionated heparin in preventing venous thromboembolism in surgical patients. Aspirin and clopidogrel are antiplatelet medications that are more commonly used for preventing arterial thrombosis rather than venous thrombosis. Alteplase is a thrombolytic medication used to dissolve existing blood clots, rather than prevent their formation.
Question 5 of 5
The ophthalmologist asks the nurse to prepare to assist in the administration of tetracaine, fluorescein stain, and atropine for a diagnostic eye examination. Before assisting in the procedure, it is most important for the nurse to inform the ophthalmologist if the patient has a history of which condition?
Correct Answer: B
Rationale: Atropine is a mydriatic agent that dilates the pupil and can precipitate angle-closure glaucoma in patients with a narrow anterior chamber angle. Therefore, it is critical to inform the ophthalmologist if the patient has a history of angle-closure glaucoma. Cataracts (A), open-angle glaucoma (C), and macular degeneration (D) are not contraindications for the use of atropine.
