What is a common, serious complication of rheumatic fever?

Answer is: d. Apply direct pressure above the catheterization site.

Explanation: The first action should be to apply direct pressure above the catheterization site to help control the bleeding and minimize blood loss. This will also give the nurse time to prepare additional interventions or supplies if necessary.

Choice a. is wrong because placing the child in the Trendelenburg position is not an appropriate initial nursing action in this scenario. This position can increase intracranial pressure and is typically used for patients experiencing shock or hypotension.

Choice b. is wrong because applying a new bandage with more pressure might be a subsequent action, but the priority is to apply direct pressure to slow down the bleeding.

Choice c. is wrong because notifying the physician is important, but the nurse should first take immediate action to control the bleeding and minimize potential harm to the patient.

The correct answer is Choice A.Choice A rationale:Vomiting is a common sign of digoxin toxicity. It occurs due to the drug's effects on the gastrointestinal system, which can lead to nausea and vomiting as the body attempts to expel the toxin. This symptom is particularly significant as it can indicate elevated digoxin levels that may require medical intervention.Choice B rationale:Tachycardia, or an increased heart rate, can occur with digoxin toxicity; however, it is more commonly associated with inadequate therapeutic levels rather than toxicity itself. Digoxin usually causes bradycardia (a slower heart rate) when at therapeutic levels, making tachycardia less indicative of toxicity.Choice C rationale:Bradypnea, or slow breathing, is not a typical sign of digoxin toxicity. While respiratory issues can arise from various conditions, they are not specifically linked to digoxin levels. Monitoring respiratory rate is essential in clinical settings but does not directly correlate with digoxin toxicity.Choice D rationale:Seizures are not a common sign of digoxin toxicity. While severe cases might lead to neurological symptoms due to electrolyte imbalances or other complications, seizures are not typically associated with digoxin overdose. Instead, they may suggest other underlying issues requiring evaluation.
