A patient is in the intensive care unit because of an acute myocardial infarction. He is experiencing severe ventricular dysrhythmias. The nurse will prepare to give which drug of choice for this dysrhythmia?

Correct Answer: C

Rationale: Amiodarone is the drug of choice for treating severe ventricular dysrhythmias, such as those experienced by the patient in the intensive care unit with acute myocardial infarction. It is a class III antiarrhythmic medication that works by prolonging the action potential duration and refractory period, thereby helping to stabilize the electrical activity of the heart. Amiodarone is effective in treating various types of ventricular dysrhythmias, including ventricular tachycardia and ventricular fibrillation, making it a suitable choice in this scenario. Diltiazem and verapamil are calcium channel blockers primarily used for supraventricular arrhythmias and are not the first-line treatment for severe ventricular dysrhythmias. Adenosine is used for terminating supraventricular tachycardias, not ventricular dysrhythmias. Amiodarone

Correct Answer: C

Rationale: A solution is a liquid preparation that contains one or more chemical substances dissolved in a suitable solvent. The solute (chemical substance) is evenly dispersed and mixed with the solvent, resulting in a homogenous mixture. Solutions are commonly used in medicine for oral administration, injections, topical treatments, and various other applications due to their ability to provide accurate dosing and rapid absorption into the body. decoction is a liquid derived from boiling plant material, fluid extract is a concentrated liquid extract of a substance, spirits are alcoholic solutions, and syrup is a viscous solution containing sugar.

Correct Answer: B

Rationale: Acetaminophen overdose is hepatotoxic and can cause severe liver damage, leading to liver failure if not treated promptly. The liver metabolizes acetaminophen into a toxic metabolite, N-acetyl-p-benzoquinone imine (NAPQI), which depletes glutathione stores and causes cellular damage. Early administration of N-acetylcysteine (NAC) is critical to prevent irreversible liver damage. While kidney injury can occur, it is less common than liver damage.

Correct Answer: C

Rationale: The patient's unresponsiveness after receiving morphine is likely due to opioid-induced respiratory depression, a potentially life-threatening side effect. The nurse should first assess the patient's airway, breathing, and circulation (ABCs) and call for additional assistance. Supporting breathing with a bag-valve-mask device is critical to ensure adequate oxygenation. Naloxone, an opioid antagonist, should be prepared to reverse the effects of morphine. Flumazenil (A) is used for benzodiazepine overdose, not opioids. Reporting a stroke (B) is incorrect because the symptoms are consistent with opioid toxicity, not a stroke. Explaining unresponsiveness as a desired outcome (D) is inappropriate and dangerous.
