A nurse is caring for a client who has a cardiopulmonary arrest. The nurse anticipates the emergency response team will administer which of the following medications if the client's restored rhythm is symptomatic bradycardia?

Magnesium

Sodium bicarbonate

Epinephrine

Atropine

Answer and Explanation

The Correct Answer is D

Choice A Reason: This is incorrect because magnesium is not a medication for symptomatic bradycardia. Magnesium is a mineral that regulates muscle and nerve function, blood pressure, and blood sugar levels. Magnesium can be used to treat conditions such as torsades de pointes, eclampsia, or hypomagnesemia.

Choice B Reason: This is incorrect because sodium bicarbonate is not a medication for symptomatic bradycardia. Sodium bicarbonate is a substance that neutralizes acids and bases and regulates the pH of the blood. Sodium bicarbonate can be used to treat conditions such as metabolic acidosis, cardiac arrest, or overdose of certain drugs.

Choice C Reason: This is incorrect because epinephrine is not a medication for symptomatic bradycardia. Epinephrine is a hormone that activates the sympathetic nervous system and increases the heart rate, blood pressure, and blood ﬂow to the muscles and brain. Epinephrine can be used to treat conditions such as anaphylaxis, cardiac arrest, or severe asthma.

Choice D Reason: This is correct because atropine is a medication for symptomatic bradycardia. Atropine blocks the action of the parasympathetic nervous system and increases the heart rate and conduction. Atropine is a medication that blocks the action of the parasympathetic nervous system and increases the heart rate and conduction.

Symptomatic bradycardia is a condition where the heart rate is slower than normal and causes symptoms such as dizziness, fatigue, chest pain, or fainting. Atropine can be used to treat symptomatic bradycardia by stimulating the sinoatrial node and the atrioventricular node, which are the natural pacemakers of the heart.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because droplet precautions are not sufficient to prevent the transmission of pneumonic plague. Droplet precautions are used to prevent the spread of infectious agents that are expelled through coughing, sneezing, or talking and travel only a short distance in the air. Droplet precautions include wearing a surgical mask, gown, and gloves, and placing the client in a private room or with a roommate who has the same infection.

Choice B Reason: This is incorrect because administering an antitoxin is not an intervention for pneumonic plague. An antitoxin is a substance that neutralizes the eﬀects of a toxin produced by a microorganism. Pneumonic plague is not caused by a toxin, but by a bacterial infection.

Choice C Reason: This is correct because initiating airborne precautions is an intervention for pneumonic plague. Airborne precautions are used to prevent the spread of infectious agents that can remain suspended in the air and travel over long distances. Pneumonic plague is a severe and potentially fatal infection caused by the bacterium Yersinia pestis, which can be transmited through respiratory droplets or aerosols. Airborne precautions are used to prevent the spread of infectious agents that can remain suspended in the air and travel over long distances. Airborne precautions include wearing a respirator or N95 mask, placing the client in a negative-pressure room with an air filtration system, and limiting visitors and staﬀ contact.

Choice D Reason: This is incorrect because destroying the linens after use is not an intervention for pneumonic plague. Linens that are contaminated with body ﬂuids or secretions should be handled with gloves and placed in leak-proof bags for laundering or disposal, but they do not need to be destroyed.

A. The pain usually lasts longer than 20 min. B. The pain persists with rest and organic nitrates. C. Pain can often be relieved by sitting up. D. Exertion and anxiety can trigger the pain.

Correct Answer is D

Explanation

Choice A Reason: This is incorrect. Anginal pain usually lasts less than 20 min and subsides with rest or medication. Pain that lasts longer than 20 min may indicate a myocardial infarction.

Choice B Reason: This is incorrect. Anginal pain usually responds to rest and organic nitrates, such as nitroglycerin. Pain that does not improve with these measures may indicate unstable angina or a myocardial infarction.

Choice C Reason: This is incorrect. Anginal pain is not aﬀected by the position of the client. Pain that is relieved by sitting up may indicate pericarditis or pleurisy.

Choice D Reason: This is correct. Anginal pain is caused by a temporary imbalance between the oxygen demand and supply of the myocardium. Factors that increase the oxygen demand, such as exertion, anxiety, cold, or heavy meals, can trigger anginal pain.
