A nurse is providing teaching to a client who is at 14 weeks of gestation about findings to report to the provider.

Which of the following findings should the nurse include in the teaching

1. . Answer and explanation.

The correct answer is choice C, first-degree atrioventricular block.

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.

In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

The correct answer is choice b. "I can start the medication 30 minutes earlier."Choice A rationale: This is an inappropriate response, as the nurse should not adjust the time and schedule for the administration of alteplase recombinant, which is a time-sensitive medication used to treat a thrombus in the coronary artery. The administration of this medication must be done within a specific time frame to be effective.Choice B rationale: This is the correct answer. Alteplase recombinant is a thrombolytic medication used to dissolve blood clots in the coronary artery. It is a time-sensitive medication, and it is crucial to administer it as soon as possible to minimize the damage to the heart muscle. Starting the medication 30 minutes earlier is an appropriate action to include in the plan of care, as it can help ensure the medication is administered within the recommended time frame.Choice C rationale: This is an inappropriate response. Alteplase recombinant should be administered within a specific time frame, typically within 3 to 4.5 hours of the onset of symptoms. Waiting up to 2 hours after the usual schedule time to give the medication would be outside the recommended time frame and could potentially reduce the effectiveness of the treatment.Choice D rationale: This is an inappropriate response. Alteplase recombinant should be infused at a specific rate, as recommended by the manufacturer or healthcare provider. Infusing the medication at a faster rate could increase the risk of adverse effects and should not be included in the plan of care without specific instructions from the healthcare provider.
