Pharmacology Assessment 2 ATI Capstone Questions
Question 1 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 2 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 3 of 5
Which patient problem is a priority for patients receiving epidermal growth factor receptor inhibitors?
Correct Answer: B
Rationale: Epidermal growth factor receptor (EGFR) inhibitors commonly cause skin-related side effects, such as rash, dryness, and paronychia (nail inflammation). These side effects can lead to tissue injury and discomfort, impacting the patient's quality of life. While bone marrow suppression and reduced platelet activity are concerns with other chemotherapies, they are less common with EGFR inhibitors. Alopecia is also less frequently associated with these drugs. The nurse should prioritize monitoring and managing skin-related side effects to prevent complications and ensure patient comfort.
Question 4 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.
Question 5 of 5
A patient's chart includes an order that reads as follows: 'Lanoxin 250 mcg once daily at 0900.' Which action by the nurse is correct?
Correct Answer: D
Rationale: Lanoxin (digoxin) is a medication commonly used to treat heart failure and arrhythmias. The order specifies the dosage and timing but does not indicate the route of administration. Since digoxin can be administered orally, intravenously, or intramuscularly, the nurse must clarify the route with the prescriber to ensure safe and accurate administration. Administering the medication via the wrong route could lead to serious complications, such as toxicity or ineffective treatment. Therefore, contacting the prescriber for clarification is the correct and safest action for the nurse to take.
