A 145-pound man requires a dopamine infusion at 15 µg/kg/min for
severe hypotension. You have a premixed bag containing 800 mg of
dopamine in 500 mL of normal saline. If you are using a microdrip
administration set (60 gtts/mL), how many drops per minute should you
deliver to achieve the required dose?
A: 42
B: 36
C: 48
D: 30 - CORRECT ANSWER - *B: 36*
Reason:
,First, convert the patient's weight from pounds to kilograms: 145 ÷ 2.2 =
66 kg. Next, determine the desired dose: 15 µg/kg/min × 66 kg = 990
µg/min. The next step is to determine the concentration of dopamine on
hand: 800 mg ÷ 500 mL = 1.6 mg/mL (1,600 µg/mL [1.6 × 1,000 = 1,600]).
Now, you must determine the number of mL to be delivered per minute:
990 µg/min [desired dose] ÷ 1,600 µg/mL [concentration on hand] = 0.6
mL/min. The final step is to determine the number of drops per minute
that you must set your IV flow rate at: 0.6 mL/min × 60 gtts/mL (drop
factor of the microdrip) ÷ 1 (total infusion time in minutes) = 36 gtts/min.

A 27-year-old female complains of palpitations. The cardiac monitor
reveals a narrow-complex tachycardia at 180/min. She denies any other
symptoms, and states that this has happened to her before, but it
typically resolves on its own. Her blood pressure is 126/66 mm Hg, pulse
is 180 beats/min, and respirations are 16 breaths/min. After attempting
vagal maneuvers and giving two doses of adenosine, her cardiac rhythm
and vital signs remain unchanged. You should:
A: infuse 150 mg of amiodarone over 10 minutes, reassess her, and
repeat the amiodarone if needed.
B: transport at once, reassess her frequently, and perform synchronized
cardioversion if necessary.
C: administer 5 mg of midazolam and perform synchronized
cardioversion starting with 50 joules.
D: administer 0.35 mg/kg of diltiazem over 2 minutes and then reassess
her hemodynamic status. - CORRECT ANSWER - *B: transport at once,
reassess her frequently, and perform synchronized cardioversion if
necessary.*
, Reason:
Although the patient is in supraventricular tachycardia (SVT), she
remains stable following your initial efforts to slow her heart rate with
vagal maneuvers and adenosine. Her failure to respond to initial
treatment does not automatically make her unstable. Simply transport
her, closely monitor her en route, and be prepared to cardiovert her if
she does become unstable (ie, hypotension, altered mental status, chest
pain). Unless specified in your local protocols, pharmacologic therapy
beyond adenosine (ie, calcium channel blockers, amiodarone) is typically
not indicated in the field for stable patients with SVT, although these
medications may be given in the emergency department. However, if
your protocols or medical control call for the administration of diltiazem
(Cardizem), the initial dose is 0.25 mg/kg.
