a. Recheck the heart rhythm and BP in 5 minutes.
b. Have the patient perform the Valsalva maneuver.
c. Give the scheduled dose of diltiazem (Cardizem).
d. Apply the transcutaneous pacemaker (TCP) pads.

Question 2

a. Place the transcutaneous pacemaker pads on the patient.

Answer to Question 1

ANS: D
The patient is experiencing symptomatic bradycardia, and treatment with TCP is appropriate. Continued monitoring of the rhythm and BP is an inadequate response. Calcium channel blockers will further decrease the heart rate, and the diltiazem should be held. The Valsalva maneuver will further decrease the rate.

Answer to Question 2

ANS: D
The patient has progressive first-degree atrioventricular (AV) block, and the -blocker should be held until discussing the medication with the health care provider. Documentation and assessment are appropriate but not fully adequate responses. The patient with first-degree AV block usually is asymptomatic, and a pacemaker is not indicated. Atropine is sometimes used for symptomatic bradycardia, but there is no indication that this patient is symptomatic.
