Answer and Explanation

The Correct Answer is ["21.6"]

 Convert pounds to kilograms:

198 lbs / 2.2 lbs/kg = 90 kg

 Calculate the medication dose in mcg/min:

90 kg 4 mcg/kg/min = 360 mcg/min

 Convert mcg/min to mg/hr:

360 mcg/min 60 min/hr = 21600 mcg/hr
21600 mcg/hr / 1000 mcg/mg = 21.6 mg/hr

 Determine the medication concentration:

250 mg / 250 mL = 1 mg/mL

 Calculate the infusion rate in mL/hr:

21.6 mg/hr / 1 mg/mL = 21.6 mL/hr

Correct Answer is C

Explanation

A. Sodium Bicarbonate is incorrect as it is not a first-line treatment for VF. It may be considered in cases of severe acidosis or hyperkalemia.
B. Amiodarone is incorrect as it is used as an antiarrhythmic, but epinephrine is administered first during cardiac arrest to increase perfusion.
C. Epinephrine is correct because it is the first-line drug given in ventricular fibrillation that persists after defibrillation. It increases coronary and cerebral perfusion and enhances the effectiveness of subsequent defibrillation attempts.
D. Lidocaine is incorrect as it is an antiarrhythmic that may be considered after epinephrine and amiodarone, but it is not the first choice.

A. A minor who is experiencing acute pain in the abdomen and labia after rape B. A postmenopausal woman who has bruises on the genitalia C. A sexually assaulted patient who has multiple facial fractures D. A rape victim who has an active hemorrhage in the abdomen

Correct Answer is D

Explanation

A. A minor with acute pain is incorrect because while urgent, it does not pose an immediate life-threatening risk and would likely fall into the urgent category.
B. A postmenopausal woman with bruising is incorrect because bruising alone does not indicate an immediate life-threatening condition and would be categorized as non-urgent.
C. A sexually assaulted patient with multiple facial fractures is incorrect because while serious, it is not immediately life-threatening and would likely be categorized as urgent.
D. A rape victim with active hemorrhage in the abdomen is correct because uncontrolled bleeding is life-threatening and requires immediate intervention, placing this patient in the emergent category.
