Answer to Question 1

ANS: A
Atropine is used for symptomatic bradycardia in a dose of 0.01-0.05 mg/kg, IV. This is the correct drug and dose. Norepinephrine is used to produce vasoconstriction at a dose of 0.1-1 g/kg/minute, by IV infusion.

Answer to Question 2

ANS: D
A cardiac output of 3 L/minute is low, indicating such conditions as heart failure, hypovolemia, or increased systemic vascular resistance. A weak, thready pulse would be consistent with this reading. Capillary refill of 2 seconds is normal. An increased temperature would not be related. A urine output of 3 mL/kg/hour is more than sufficient and does not indicate low cardiac output.
