ATI Pharmacology Assessment 2 Questions
Question 1 of 5
A 29-year-old man with recurrent allergic rhinitis presents to his primary care physician for evaluation. He states that his symptoms are more problematic lately and desires treatment. He has begun on fexofenadine. Which of the following adverse reactions is possible in this patient?
Correct Answer: C
Rationale: Fexofenadine, a non-sedating antihistamine, may cause headache , a common side effect. Anxiety , cough , otitis , and respiratory infection (E) are less frequent. Its minimal CNS penetration suits rhinitis, but headache requires awareness.
Question 2 of 5
The nurse is giving instructions to a client receiving phenytoin (Dilantin). The nurse concludes that the client has a sufficient knowledge if the client states that:
Correct Answer: D
Rationale: Monitoring serum phenytoin levels is essential to ensure therapeutic efficacy and avoid toxicity. Wearing a medical alert tag is recommended for clients on phenytoin. Alcohol should be avoided, and taking the medication with milk can interfere with absorption. Therefore, the correct statement indicating sufficient knowledge is about monitoring serum levels.
Question 3 of 5
Which of the following is an action of the drug Metformin?
Correct Answer: A
Rationale: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. One of the main actions of Metformin is to decrease hepatic glucose production by suppressing gluconeogenesis in the liver. By reducing the amount of glucose produced by the liver, Metformin helps lower blood sugar levels in individuals with diabetes. This action helps improve insulin sensitivity and overall glycemic control in patients with type 2 diabetes. The other options provided in the question do not describe the primary mechanism of action of Metformin.
Question 4 of 5
The nurse will be administering an antitussive medication containing codeine to a patient. What is the priority assessment?
Correct Answer: C
Rationale: Codeine, an opioid antitussive, can cause respiratory depression as a side effect. The nurse must assess the patient’s respiratory rate before administration to ensure it is within a safe range (typically >12 breaths per minute). While lung sounds (B) and sputum consistency (D) are important, they are not the priority when administering a medication that can suppress respiration. Pulse oximetry (A) is useful but secondary to direct respiratory rate assessment.
Question 5 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: Rotating the application sites of transdermal nitroglycerin patches is important to prevent skin irritation and tolerance development. By changing the site with each dose, the nurse ensures proper absorption of the medication and reduces the risk of skin reactions. It is not recommended to always apply the patch to the same site, as this can lead to localized skin irritation. It is also important to avoid using areas with a lot of hair or bony prominences, as well as to avoid areas with scars or skin folds. Rotation of application sites helps maintain the effectiveness of the nitroglycerin patch therapy.
