Question 1 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 2 of 5
A 22-year-old man has taken an overdose of sleeping pills after learning that he did not receive the job he has recently been interviewed for. He is found by his roommate conscious but not able to completely follow commands. The roommate calls the local poison control center. Instructions are given to self-administer syrup of ipecac while waiting for the rescue squad to respond. This agent has a mechanism of action that involves which of the following?
Correct Answer: B
Rationale: Syrup of ipecac induces vomiting in overdose. It stimulates the chemotactic trigger zone in the medulla-prompting emesis. Gag reflex stimulation is secondary. Suppressing pressures , gag reflex , or motor cortex (E) don't apply. Though less used now, ipecac's CNS action expels pills, aiding this acute scenario, distinct from mechanical or suppressive effects.

Question 4 of 5
Before administering Digoxin, the nurse should complete which task?
Correct Answer: B
Rationale: Before administering Digoxin, it is crucial for the nurse to count the patient's apical pulse for 1 minute. Digoxin is a medication commonly prescribed to manage heart conditions such as heart failure and certain irregular heartbeats. Since Digoxin works by helping the heart beat stronger and at a more normal rhythm, it is essential to monitor the patient's heart rate before administering the medication. Counting the apical pulse for 1 minute allows for an accurate assessment of the patient's baseline heart rate, which is crucial in determining whether it is safe to administer Digoxin. If the heart rate is too low (bradycardia), administering Digoxin could potentially cause further complications. Therefore, assessing the apical pulse beforehand is a critical step in ensuring the safe administration of Digoxin.
Question 5 of 5
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.
