ATI Pharmacology Final Exam I Questions
Extract:
Question 1 of 5
A nurse is assessing a client who has hypoxemia for a late sign. Which finding should the nurse expect?
Correct Answer: D
Rationale: Bradycardia, or a decreased heart rate, is a late sign of hypoxemia. When the body can no longer compensate for the lack of oxygen through increased heart rate and other mechanisms, it may enter a state of bradycardia.
Question 2 of 5
A client presents to the clinic with intense itching at night and is diagnosed with Pinworms. The nurse anticipates the client would be placed on which medication to treat this condition?
Correct Answer: C
Rationale: Mebendazole (Vermox) is an anthelmintic medication specifically used to treat parasitic worm infections, including pinworms. It works by inhibiting the worms' ability to absorb glucose, leading to their death.
Question 3 of 5
A client is taking cyclobenzaprine (Flexeril) for acute muscle spasms of the back. The nurse educates the client on which possible anticholinergic side effects associated with this medication? (Select all that apply)
Correct Answer: A,C,E
Rationale: Tachycardia, decreased urination, and dry mouth are anticholinergic side effects of cyclobenzaprine. These occur due to the inhibition of acetylcholine, affecting heart rate, bladder function, and salivary glands. Excessive lacrimation and sweating are not typical, as anticholinergics reduce secretions.
Question 4 of 5
A nurse is teaching a group of nurses about the administration of nitroglycerin. Which of the following routes of administration provides the most rapid onset for the client?
Correct Answer: B
Rationale: Sublingual administration provides the most rapid onset of action for nitroglycerin. The medication is absorbed directly into the bloodstream through the mucous membranes under the tongue.
Question 5 of 5
A nurse is caring for a client receiving cholinergic medications to assist in the treatment of myasthenia gravis. Which contraindication will the nurse assess for prior to administering a cholinergic medication?
Correct Answer: B
Rationale: Asthma is a contraindication for cholinergic meds because they can increase bronchoconstriction, worsening respiratory status.
