Pharmacology Practice Exam A ATI Questions
Question 1 of 9
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 2 of 9
Which solution should the nurse administer with packed red blood cells?
Correct Answer: B
Rationale: When administering packed red blood cells, it is important to use a compatible solution. The preferred solution to administer with packed red blood cells is 0.9% sodium chloride (normal saline) because it is isotonic and compatible with red blood cells. Using an isotonic solution like 0.9% sodium chloride helps to prevent hemolysis of the red blood cells and maintains their integrity during administration. Lactated Ringer's solution, D5W, and 0.45% sodium chloride are not recommended for administering packed red blood cells because they can cause hemolysis due to their hypotonic or hypertonic nature.
Question 3 of 9
What is a severe adverse effect of warfarin?
Correct Answer: A
Rationale: Warfarin is an anticoagulant medication commonly used to prevent blood clots. One of the most severe adverse effects of warfarin is the risk of bleeding. This can occur in various parts of the body, such as the gastrointestinal tract, brain, or other organs. Bleeding complications can range from minor bruising to life-threatening hemorrhages, especially if warfarin levels are not properly monitored. Patients taking warfarin should be closely monitored for signs of bleeding, and their medication dosages should be adjusted as needed to maintain a balance between preventing clotting and avoiding excessive bleeding.
Question 4 of 9
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 5 of 9
Antilipemic drug therapy is prescribed for a patient, and the nurse is providing instructions to the patient about the medication. Which instructions will the nurse include? (Select all that apply.)
Correct Answer: D
Rationale: Abnormal or unusual bleeding could be A sign of A potential side effect or complication related to antilipemic drug therapy. Yellow discoloration of The skin may indicate liver issues, which could be A serious side effect of certain antilipemics. Therefore, it is important for The patient to report these symptoms immediately to their healthcare provider for further evaluation.
Question 6 of 9
Dobutamine:
Correct Answer: D
Rationale: Dobutamine, a β1-selective agonist, can cause arrhythmias, so no arrhythmogenic effect is false. It increases myocardial oxygen consumption by enhancing contractility, not decreases it. It's selective, not non-selective, targeting cardiac β1 receptors. It doesn't act on CNS D2 dopamine receptors but on peripheral β1. It's used in heart failure to boost cardiac output, a true statement, making it valuable in acute settings. This inotropic effect distinguishes it from non-selective agents, critical for managing cardiogenic shock.
Question 7 of 9
A nurse is caring for a client with a history of overdosage of aspirin. The nurse suspects which of the following can be an early sign of aspirin toxicity?
Correct Answer: D
Rationale: Tinnitus, or ringing in the ears, can be an early sign of aspirin toxicity. Aspirin poisoning can lead to salicylate toxicity, which can manifest with various symptoms including tinnitus, along with hyperventilation, nausea, vomiting, and metabolic acidosis. Monitoring for tinnitus is crucial as an early indicator of potential aspirin overdose in clients. Unsteady gait, drowsiness, and confusion are also symptoms of aspirin toxicity but typically develop after tinnitus in the progression of toxicity.
Question 8 of 9
The following drugs are effectively administered via the sublingual route:
Correct Answer: D
Rationale: Glyceryl trinitrate is well-absorbed sublingually due to bypassing the first-pass metabolism, providing rapid relief for angina by dilating blood vessels.
Question 9 of 9
The nurse is caring for a client receiving IV heparin. Which finding requires immediate action?
Correct Answer: B
Rationale: Heparin anticoagulates, monitored by aPTT (therapeutic: 60-80 seconds). An aPTT of 90 seconds indicates over-anticoagulation, risking bleeding, needing immediate action (e.g., stop infusion). Bruising and redness are minor. Platelets of 150,000 are normal. Prolonged aPTT aligns with heparin's effect, critical in therapy where bleeding is a threat, making B the finding requiring swift response.
