A client on a cardiac unit is experiencing atrial fibrillation with a rapid ventricular response of 140 beats per minute. The client is dizzy, short of breath, and hypotensive. Medications have not been effective at reducing the client's heart rate. Which procedure would the nurse anticipate to be performed for this client?
Defibrillation
Coronary artery stent placement
Echocardiogram
Synchronized cardioversion
The Correct Answer is D
A. Defibrillation is used to treat life-threatening arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia, where the heart is in a chaotic rhythm without an effective contraction.
B. This procedure is performed to relieve significant blockages in coronary arteries that are causing myocardial ischemia or infarction. While coronary artery disease can contribute to cardiac issues, it is not the primary intervention for treating atrial fibrillation with a rapid ventricular response and associated symptoms like dizziness, shortness of breath, and hypotension.
C. While an echocardiogram may be useful in assessing the overall cardiac function and structure, it is not an immediate intervention for the acute management of atrial fibrillation with a rapid ventricular response and unstable symptoms.
D. Synchronized cardioversion is a procedure used to convert certain types of rapid arrhythmias, including atrial fibrillation, to a normal sinus rhythm by delivering a synchronized electrical shock to the heart at a specific point in the cardiac cycle.

Correct Answer is C
Explanation
A. A vegetarian diet typically does not directly contribute to bronchoconstriction. In fact, a diet rich in fruits and vegetables may provide antioxidants and anti-inflammatory compounds that can be beneficial for respiratory health. Therefore, this option is less likely to be a cause of the client's bronchoconstriction.
B. Rosuvastatin (and other statins) are generally well-tolerated, but some individuals may experience respiratory side effects, including cough or shortness of breath. However, bronchoconstriction as a direct side effect of statins is uncommon and typically not a primary concern unless there is a rare hypersensitivity reaction.
C. Propranolol is a non-selective beta-blocker that can lead to bronchoconstriction, particularly in individuals with asthma or other respiratory conditions. Beta-blockers can block beta-2 receptors in the lungs, potentially causing constriction of the airways and worsening of respiratory symptoms.
D. Acetaminophen (paracetamol) is generally considered safe and does not typically cause bronchoconstriction. It is a non-steroidal anti-inflammatory drug (NSAID) that works differently from medications like beta-blockers, which directly affect the airways.
Correct Answer is A
Explanation
A. By surrounding themselves with familiar items, such as photos, favorite objects, or comforting decor from their previous home, the resident can feel more at ease and connected to their past. This approach helps in creating a more homelike atmosphere and reducing feelings of disorientation and stress associated with the move.
B. Isolating the resident and encouraging avoidance of social interactions can exacerbate feelings of loneliness, isolation, and anxiety. Avoiding social interactions may prolong feelings of stress and hinder adaptation to the new living situation.
C. While it's important to manage the frequency and timing of visits to ensure the resident is not overwhelmed, outright restricting visitation hours can be counterproductive. Restricting visitation could increase feelings of isolation and loneliness, which are already common in new residents of long-term care facilities.
D. Using sedative medications should be reserved for situations where non-pharmacological interventions have been unsuccessful and the resident's anxiety or distress is severe and persistent. Sedatives can have side effects, especially in older adults, and should not be the first-line approach for managing relocation stress syndrome.
