Which drug is used to reverse the e昀昀ects of an opioid overdose?

Correct Answer: C

Rationale: Naloxone is the drug used to reverse the effects of an opioid overdose. It is an opioid antagonist that rapidly binds to opioid receptors in the brain, displacing the opioid molecules. By blocking the receptor sites, naloxone can quickly reverse the effects of opioids, such as respiratory depression, sedation, and potential coma. Naloxone is a critical medication in opioid overdose situations as it can restore normal breathing and save a person's life. It is often available in the form of a nasal spray or injection for emergency use. It is essential for first responders, healthcare professionals, and individuals at risk of opioid overdose to have access to naloxone as part of overdose prevention and harm reduction strategies.

Correct Answer: B

Rationale: Theophylline overdose (empty bottle) causes cardiac arrhythmias . Toxicity leads to tachyarrhythmias, often fatal. Apnea is secondary. Pulmonary embolism lacks context. Seizures occur but aren't primary. Tetany (E) is unrelated. Arrhythmias align with theophylline's narrow therapeutic index.

Correct Answer: B

Rationale: In a hypertensive emergency where a patient's blood pressure is extremely elevated (such as 270/150 mm Hg in this case), one of the medications commonly used is a titratable intravenous antihypertensive medication like nicardipine. The maximum dose of nicardipine that should be infused is typically guided by the patient's response to treatment and not a fixed duration of time. Therefore, the correct answer is B, as it highlights the importance of titrating the medication based on the patient's blood pressure response, rather than a specific time frame for infusion. Utilizing the drug at the lowest effective dose is crucial to avoid potential adverse effects, especially in a hypertensive emergency scenario.

Correct Answer: A

Rationale: Albuterol is an example of a bronchodilator medication commonly used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Bronchodilators work by relaxing the muscles in the airways, which helps to open up the air passages and improve airflow to the lungs. This action can help relieve symptoms like wheezing, shortness of breath, and chest tightness. Albuterol is typically administered via inhalation to provide quick relief during an asthma attack or COPD exacerbation.

Correct Answer: A

Rationale: For a 79-year-old patient taking a diuretic for hypertension, the nurse should know that extra precautions are necessary for preventing orthostatic hypotension and potential falls. Orthostatic hypotension refers to a drop in blood pressure that occurs when standing up from a sitting or lying down position. This can lead to dizziness and an increased risk of falls, particularly in elderly individuals. Therefore, the teaching point about taking extra precautions when standing up is critical to emphasize for this patient to ensure their safety and well-being. Option A is the correct choice as it highlights the importance of this teaching point for the patient's care.
