A nurse is caring for a client who taking benztropine to treat Parkinson's disease. The nurse should instruct the client to monitor and report which of the following side effects of benztropine?

Bradycardia

Excess salivation

Urinary retention

Diarrhea

Answer and Explanation

The Correct Answer is C

A) Bradycardia:
Benztropine is an anticholinergic medication used to manage the symptoms of Parkinson's disease by blocking the action of acetylcholine. While anticholinergic medications can affect heart rate, bradycardia is not a common side effect of benztropine. In fact, benztropine may have the opposite effect, potentially causing tachycardia (increased heart rate).

B) Excess salivation:
Excessive salivation is typically a symptom of Parkinson's disease itself, due to difficulty swallowing, rather than a side effect of benztropine. In fact, benztropine, as an anticholinergic agent, generally reduces salivation (anticholinergic effect), so this side effect is unlikely to occur with benztropine therapy.

C) Urinary retention:
Benztropine, being an anticholinergic drug, can inhibit the action of acetylcholine at muscarinic receptors in the bladder, leading to urinary retention. This is a common and serious side effect of anticholinergic drugs like benztropine. Urinary retention can lead to discomfort, urinary tract infections (UTIs), and kidney problems if not addressed.

D) Diarrhea:
Benztropine is more likely to cause constipation rather than diarrhea due to its anticholinergic effects. Anticholinergic medications often slow down gastrointestinal motility, leading to constipation.

Correct Answer is A

Explanation

A. Synchronized cardioversion: Synchronized cardioversion is indicated for unstable supraventricular tachycardia (SVT), especially when the client shows signs of hemodynamic instability, such as hypotension, altered mental status, or chest pain. This intervention delivers a timed shock to restore normal rhythm, prioritizing the client's immediate stabilization.

B. Adenosine infusion over 30 minutes: Adenosine is typically administered as a rapid intravenous push to terminate SVT by temporarily blocking atrioventricular nodal conduction. However, this client is unstable, and synchronized cardioversion is the preferred intervention in cases of hemodynamic compromise.

C. Immediate defibrillation: Defibrillation is used for life-threatening arrhythmias like ventricular fibrillation or pulseless ventricular tachycardia. In this case, the rhythm is SVT, and the client is not in cardiac arrest, so defibrillation is inappropriate.

D. Vagal maneuvers: Vagal maneuvers, such as carotid sinus massage or the Valsalva maneuver, are first-line interventions for stable SVT. However, in unstable clients with severe symptoms or hemodynamic compromise, these measures are insufficient, and synchronized cardioversion is urgently required.

A. Prednisone B. Metropolol C. Labetolol D. Albuterol

Correct Answer is B

Explanation

A) Prednisone:
Prednisone is a corticosteroid commonly used to reduce inflammation in conditions such as asthma. It is appropriate in this case for managing the asthma exacerbation, as steroids help to decrease airway inflammation and improve breathing. There is no immediate concern about prednisone in this client with both asthma and a history of heart failure.

B) Metoprolol:
Metoprolol is a beta-blocker, typically used for managing heart failure, hypertension, and arrhythmias. However, beta-blockers are generally avoided in asthma patients because they can exacerbate bronchospasm. In patients with asthma, beta-blockers can block beta-2 receptors in the lungs, leading to constriction of the airways and worsening respiratory symptoms.

C) Labetolol:
Labetolol is a beta-blocker with both alpha- and beta-blocking effects, which can help lower blood pressure and manage heart failure. While labetalol can also block beta-2 receptors, it has a relatively lower risk of causing bronchospasm compared to non-selective beta-blockers like metoprolol. However, it still poses some risk to patients with asthma. Given the patient's history of asthma, labetolol may still require caution, but it is generally considered safer than other beta-blockers.

D) Albuterol:
Albuterol is a bronchodilator used to relieve acute asthma symptoms and is commonly prescribed for asthma exacerbations. It works by stimulating beta-2 receptors in the lungs, leading to the relaxation of bronchial smooth muscles and improved airflow. In this case, albuterol is an appropriate medication for managing asthma exacerbation and should be used to relieve symptoms of shortness of breath and wheezing.
