Pharmacology Assessment 2 ATI Capstone Questions
Question 1 of 5
What is Montelukast used for?
Correct Answer: A
Rationale: Montelukast is primarily used for the prevention and treatment of asthma. It is a leukotriene receptor antagonist that works by blocking leukotrienes, substances in the body that cause symptoms of asthma and allergic rhinitis. By blocking leukotrienes, Montelukast helps to reduce inflammation in the airways, decrease bronchoconstriction, and ultimately improve asthma symptoms and prevent asthma attacks. It is not used for lowering pain levels, treating depression, or improving wakefulness in patients.
Question 2 of 5
Which classification of drugs would the nurse refuse to administer to a pregnant patient?
Correct Answer: D
Rationale: Teratogenic drugs (e.g., thalidomide) cause fetal harm, absolute no-go in pregnancy, per safety. Category A is safe (e.g., levothyroxine). Category B has no human risk (e.g., metformin). ‘Cautionary' isn't a class-teratogenic fits X or known risks. Refusing teratogens protects the fetus, a clear rule.
Question 3 of 5
The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask?
Correct Answer: D
Rationale: Oxymetazoline causes rebound congestion if used beyond 3-5 days. Asking 'How long have you been using the medication?' identifies misuse, the likely cause of worsening symptoms. Bottle age , temperature , and other medications are secondary. D targets the root issue, making it the best question.
Question 4 of 5
The patient accidentally takes too much of the prescribed warfarin (Coumadin) and is readmitted to the hospital with bleeding. Which drug can the nurse anticipates administrating?
Correct Answer: D
Rationale: In the scenario described where the patient has accidentally taken too much warfarin (Coumadin) and is experiencing bleeding, the nurse can anticipate administering Vitamin K. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the liver. By administering Vitamin K, it helps reverse the anticoagulant effect of warfarin by supplying the needed vitamin K for the production of clotting factors. This aids in the clotting process and helps to stop the bleeding that may occur due to excess warfarin in the system. Other medications listed (such as Protamine sulfate, Alteplase, Reteplase) are not specific antidotes for warfarin overdose-related bleeding but are used for different therapeutic purposes.
Question 5 of 5
A 71-year-old man who has chronic back pain after falling from a first-floor apartment 25 years ago is managed with a morphine pump for his chronic pain. He also had a long history of chronic diarrhea that preceded his accident. The pump has been in place for 22 years. Which of the following effects will still likely be maintained by the device at this time?
Correct Answer: B
Rationale: Long-term morphine via pump sustains certain effects. Constipation persists-tolerance doesn't fully develop to GI μ-receptor effects, unlike analgesia , euphoria , or sedation (E). Pupil dilation is incorrect; morphine causes miosis. After 22 years, constipation remains a chronic issue, reflecting opioid pharmacology.
