Pharmacology Practice Exam A ATI Questions
Question 1 of 5
Which of the following is NOT a side effect of Alprazolam?
Correct Answer: C
Rationale: Insomnia is not a common side effect of Alprazolam. Alprazolam is a benzodiazepine medication commonly used to treat anxiety and panic disorders. Common side effects of Alprazolam include dizziness, drowsiness, and lethargy. However, it is not typically associated with causing insomnia as a side effect. If a person experiences unusual symptoms while taking Alprazolam, they should consult their healthcare provider for guidance.
Question 2 of 5
Which of the following best describes H1 receptor antagonist:
Correct Answer: D
Rationale: H1 receptor antagonists are primarily used for the treatment and prevention of allergic reactions. They work by blocking the H1 receptors, which are responsible for mediating allergic responses such as itching, swelling, and inflammation. This action helps to alleviate symptoms of allergies like sneezing, itching, and runny nose.
Question 3 of 5
The nurse is performing a health history on a patient who is ordered to begin therapy with valproic
Correct Answer: D
Rationale: Valproic acid is metabolized in the liver, and patients with liver disease may have impaired liver function, which can lead to reduced metabolism of the drug and potential toxicity. Therefore, a patient with a history of liver disease starting therapy with valproic acid would be a cause for concern for the nurse. Monitoring of liver function tests would be crucial in this patient population to ensure the medication is being safely metabolized.
Question 4 of 5
A priority nursing assessment for a patient who is to receive an alpha- or beta-adrenergic blocking agent would be what?
Correct Answer: D
Rationale: The most serious adverse effect would be severe bradycardia, so the nurse’s priority would be assessing the heart rate. If the patient were identified as having diabetes, then monitoring blood glucose levels would become important because these drugs can aggravate diabetes by blocking sympathetic response including masking the usual signs and symptoms of hypoglycemia and hyperglycemia. Respiratory rate could be impacted if the patient was identified as having a condition causing bronchospasm and diabetes because the combination could worsen both conditions. Measuring urine output should be part of the patient’s care, but it is not the priority assessment.
Question 5 of 5
The nurse is reviewing a patient's laboratory test results and current medications and notes that the patient's prothrombin time is prolonged. The nurse checks the patient's medication list. What vitamin or mineral might be contributing to this?
Correct Answer: D
Rationale: Vitamin E can interfere with vitamin K-dependent clotting factors, leading to prolonged prothrombin time and increased bleeding risk. Vitamin A (A), selenium (B), and vitamin D (C) do not typically affect coagulation. The nurse should assess for excessive vitamin E supplementation or dietary intake.
