Pharmacology Practice Exam A ATI Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A patient is undergoing major surgery and asks the nurse about a living will. He states, 'I don't want anybody making decisions for me. And I don't want to prolong my life.' The patient is demonstrating
Correct Answer: A
Rationale: Autonomy refers to the patient's right to make informed decisions about their own healthcare. By expressing a desire to avoid life-prolonging measures and requesting a living will, the patient is exercising his autonomy. Beneficence involves acting in the patient's best interest, justice refers to fairness in healthcare, and veracity involves truth-telling. The patient's statements align most closely with the principle of autonomy, as he is asserting his right to control his medical care.
Question 5 of 5
Dr. Smith orders a gram of human salt poor albumin product for a patient. The product is available in a 50-milliliter vial with a concentration of 25 percent. What dosage will the nurse administer?
Correct Answer: D
Rationale: A 25 percent albumin solution contains 25 grams of albumin per 100 milliliters. To administer 1 gram of albumin, the nurse would calculate the volume as follows: 1 gram ÷ 25 grams/100 milliliters = 4 milliliters. Therefore, the nurse will administer 4 milliliters of the 25 percent albumin solution to deliver the ordered dose of 1 gram. Using the entire vial or not using the product at all would be incorrect.
