The nurse is assessing a client with a heart rate of 124 bpm. What clinical finding(s) should the nurse assess as causes of tachycardia? Select all that apply.

Defibrillation is not the first-line treatment for atrial fibrillation. It is used to treat life-threatening cardiac arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. Atrial fibrillation, on the other hand, is a rapid and irregular atrial rhythm, and defibrillation is not indicated for its treatment.

Obtain consent for transesophageal echocardiogram (TEE): This is an appropriate action for a client with atrial fibrillation. A TEE is often performed to assess the structure and function of the heart in cases of atrial fibrillation, especially when considering cardioversion or other interventions.

Obtain consent for cardioversion: Cardioversion is a common treatment option for atrial fibrillation, especially when the client is unstable or experiencing symptoms. It involves restoring a normal heart rhythm through the use of electrical shocks or medications. It is important to obtain informed consent before performing cardioversion, but this does not necessarily require questioning.

Hold digoxin 48 hours prior to cardioversion: Digoxin is commonly held before cardioversion because it can increase the risk of certain arrhythmias during the procedure. This is a standard precaution to minimize potential adverse effects. Therefore, the nurse does not need to question this action, as it aligns with established guidelines.

Hypertension is typically diagnosed when a person's blood pressure consistently exceeds 130/80 mm Hg on multiple occasions. However, the specific target blood pressure for treatment may vary based on individual factors and the presence of other comorbidities.

Among the options provided, a blood pressure reading of 128/76 mm Hg is within the target range for many individuals with hypertension. The systolic pressure (128 mm Hg) is below the threshold of 130 mm Hg, and the diastolic pressure (76 mm Hg) is below the threshold of 80 mm Hg.

The other blood pressure readings would warrant further evaluation or possible changes in therapy:

128/92 mm Hg: The diastolic pressure (92 mm Hg) is above the threshold of 80 mm Hg, indicating uncontrolled hypertension.

98/56 mm Hg: This blood pressure reading is below the threshold for hypertension, but it is considered low and may require further assessment to determine if it is normal for the individual or if it indicates hypotension.

142/78 mm Hg: While the systolic pressure (142 mm Hg) is slightly above the threshold of 130 mm Hg, it may not necessarily require immediate changes in therapy. However, it should be closely monitored to ensure blood pressure control.
