A nurse is assessing a client who has early symptoms of hypoxia. Which of the following findings should the nurse expect?

Unstable Supraventricular Tachycardia: Synchronized Cardioversion

Unstable Bradycardia: Transcutaneous Pacing

Ventricular Fibrillation: Defibrillation

Ventricular Tachycardia with No Pulse: Defibrillation

Unstable Atrial Flutter: Synchronized Cardioversion

Rationales:

Unstable Supraventricular Tachycardia – Synchronized Cardioversion:

Synchronized cardioversion delivers a timed electrical shock to the heart during the R wave, avoiding the vulnerable T wave, which minimizes the risk of inducing ventricular fibrillation. This intervention is preferred for unstable SVT unresponsive to medications, as it restores normal sinus rhythm effectively.

Unstable Bradycardia – Transcutaneous Pacing:

Transcutaneous pacing provides electrical impulses to stimulate the heart when intrinsic conduction is insufficient. It is the recommended treatment for symptomatic bradycardia that does not respond to medications, ensuring adequate cardiac output while awaiting more definitive treatment.

Ventricular Fibrillation – Defibrillation:

Defibrillation delivers an unsynchronized shock to depolarize the entire myocardium, allowing the heart to reset and resume an organized rhythm. It is the first-line intervention for ventricular fibrillation, as the chaotic electrical activity makes the heart incapable of pumping blood.

Ventricular Tachycardia with No Pulse – Defibrillation:

Pulseless ventricular tachycardia requires defibrillation, as the rhythm is life-threatening and the absence of a pulse indicates the heart is not effectively pumping. This unsynchronized shock interrupts the abnormal rhythm, allowing normal sinus rhythm to potentially resume.

Unstable Atrial Flutter – Synchronized Cardioversion:

Synchronized cardioversion is used for unstable atrial flutter to restore sinus rhythm by delivering a precisely timed electrical shock. It is effective when pharmacological measures have not worked or are inappropriate, especially in cases of hemodynamic instability.

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.
