A nurse is caring for an infant who has coarctation of the aorta.

Which of the following should the nurse identify as an expected finding?

The systolic pressure is estimated by noting the pressure at which the pulse disappears and reappears. The diastolic pressure is not measured by this method, but it can be useful when the sounds are difficult to hear.

Choice A is wrong because applying the largest cuff available can result in a falsely low reading. The cuff size should be appropriate for the client’s arm circumference.

Choice C is wrong because placing the arm above the level of the client’s heart can also cause a falsely low reading. The arm should be at the level of the heart for an accurate measurement.

Choice D is wrong because deflating the cuff quickly can lead to missing or skipping sounds, resulting in an inaccurate reading. The cuff should be deflated slowly and evenly.

Normal ranges for blood pressure vary depending on age, sex, and health conditions, but generally, a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg are considered normal for adults.

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.
