A nurse is caring for a client who has symptomatic sinus bradycardia. The Atropine was given but was not successful. Which one of the following is the next intervention?
External cardiac pacemaker
Amiodarone
Magnesium
Cardioversion
The Correct Answer is A
A. External cardiac pacemaker: If atropine is ineffective in treating symptomatic sinus bradycardia, the next step is the use of an external cardiac pacemaker which helps regulate the heart rate by providing electrical stimulation to the heart, addressing the bradycardia and improving circulation.
B. Amiodarone: Amiodarone is an antiarrhythmic drug used for treating ventricular arrhythmias or atrial fibrillation, not for bradycardia. The priority for bradycardia management is pacing rather than antiarrhythmic medications.
C. Magnesium: Magnesium is primarily used for treating specific arrhythmias like torsades de pointes, particularly in the presence of hypomagnesemia. It is not indicated for symptomatic sinus bradycardia, especially after atropine fails.
D. Cardioversion: Cardioversion is used to treat arrhythmias such as atrial fibrillation or supraventricular tachycardia, not bradycardia. Since the issue is a slow heart rate, not an abnormal rhythm needing electrical shock, cardioversion is not appropriate in this case.

Correct Answer is B
Explanation
C. Ease the visitor to the floor: This is the first priority to prevent injury. Safely guiding the person to the ground helps reduce the risk of trauma from falling.
A. Maintain a patent airway: Once on the ground, the nurse should position the person (ideally on their side) to promote airway patency and prevent aspiration.
D. Obtain vital signs: After the seizure ends, assessing vital signs helps evaluate postictal status and detect any complications such as hypoxia or hypotension.
B. Record the seizure activity observed: Documentation of the seizure’s onset, duration, and characteristics is important, but it comes after safety and assessment priorities are addressed.
Correct Answer is B
Explanation
A. Fluctuations in the fluid level in the water-seal chamber: Fluctuations, also known as "tidaling," in the water-seal chamber are normal and indicate that the chest tube is properly draining. It reflects the changes in intrathoracic pressure during respiration.
B. Continuous bubbling in the water-seal chamber: Continuous bubbling in the water-seal chamber indicates an air leak in the system, which is a complication. The water-seal chamber should only bubble intermittently as the patient exhales or coughs, not continuously.
C. Constant bubbling in the suction-control chamber: Continuous bubbling in the suction-control chamber is normal if the suction is properly set. This chamber is designed to allow constant bubbling to maintain appropriate suction pressure, not related to an air leak.
D. Occasional bubbling in the water-seal chamber: Occasional bubbling in the water-seal chamber can occur when the patient coughs or exhales, and it is a normal finding. This does not indicate a complication or air leak.
