A nurse is interpreting a client’s ECG strip.
Which of the following components of the ECG should the nurse examine to determine the time it takes for ventricular depolarization and repolarization?

Choice A rationale

Assessing pulses in the affected arm ensures proper blood flow and identifies potential complications like arterial occlusion following cardiac catheterization. Monitoring for changes can prevent severe outcomes. Normal pulse rates: 60-100 bpm.

Choice B rationale

Keeping the client NPO post-procedure is unnecessary as food and liquids can typically be resumed once the patient is stable, unless specific medical instructions indicate otherwise.

Choice C rationale

Light pressure on the insertion site is insufficient for hemostasis. Firm pressure for 10-15 minutes is necessary to prevent bleeding and hematoma formation, especially in arterial catheterization sites.

Choice D rationale

Immediate ambulation post-cardiac catheterization risks bleeding and hematoma at the insertion site. Bed rest and activity restrictions should be maintained until hemostasis is confirmed, typically for 2-6 hours.

Choice A rationale

A red and beefy tongue suggests nutritional deficiencies like iron or vitamin B12 deficiency, not digoxin toxicity.

Choice B rationale

Constipation is a gastrointestinal issue, commonly related to diet, fluid intake, or other medications, not an indicator of digoxin toxicity.

Choice C rationale

Digoxin toxicity often manifests as visual disturbances, such as yellow or blurred vision, due to its effect on the central nervous system.

Choice D rationale

Weight gain is not associated with digoxin toxicity but may result from other conditions such as hypothyroidism or fluid retention.
