Q

Barbara is given adrenaline for cardiac arrest. She was already given 1 mg of Adrenaline. She weighs 200 Ibs. How much mcg do you need to maintain the patient at until desired blood pressure is obtained?

A

Convert: 200 Ibs/ 2.2 = 90 kg

Maintain at 0.5 mcg/kg/min

Therefore = 90 kg x 0.5 mcg = 45 mcg per min

Q

Kezia was noted to have symptomatic bradycardia. She has a history of CHF and Shock. What medication would be administered?

A

Dopamine

22
Q

Kezia weighs 155 Ibs and has CHF/ shock with an episode of symptomatic bradycardia. The doctor orders 1.4 mg per min? Is this a safe dose for Dopamine?

A

Convert= 155 / 2.2 = 70.4 kg
Ordered dose = 1.4 mg x 1000 = 1,400 mcg

Dopamine dose = 2 - 20 mcg/kg/min

Safe dose = 70.4 x 2 = 140 mcg/min
= 70.4 x 20= 1,408 mcg/min

Yes, the dose is safe as it falls within the safe dose range of 140 mcg - 1,408 mcg/min

23
Q

Hint: This rhythm can also be pulseless

A

Torsades de pointes
Magnesium sulphate

24
Q

Jessyka who has a torsades de pointes rhythm, is in cardiac arrest. How much MgSO4 would be administered?

A

1 - 2 g in 10 ml D5W IV push

25
Q

Relisha has torsades de pointes but isn’t in cardiac arrest. How much MgSO4 would be administered?

A

1 - 2 g IV over 5 - 60 min

26
Q

How do you maintain MgSO4 sulphate?

A

0.5 - 1 g/hr IV

27
Q

A patient with a wide QRS tachycardia or VT with pulse cannot use Amiodarone. What can they be given?

A

Procainamide

28
Q

Your patient has a wide QRS tachycardia or VT with pulse. As the RN, you reviewed the patient’s ECG and have concluded the patient can be taken off of procainamide. What indications would provide this evaluation?

i) Rhythm improved
ii) B/P of 80/55 mmHg
iii) HR 156 bpm
iv) QRS widens by 50%

A) i & iv
B) i, iv & iii
C) i, ii, iv
D) All of the above

A

C

29
Q

The doctor orders 38 mg/min of procainamide as an initial dose for a patient with a wide QRS tachycardia. Is this a safe dose and why?

Part 2, the patient’s weight is 98 kg, what would be their max dose.

A

Yes, falls between the range of 2 - 50 mg/min

Max dose = 17 mg x 98 = 1,666 mg = 1.7 g

30
Q

How should you dilute procainamide and what rate to put the drip?

A

1 - 2 g in 250/500 ml

Drip @ 1 - 4 mg/min

31
Q

The doctor orders procainamide for a prolonged QT. The patient has CHF, do you administer?

A

No, you do not use procainamide for these conditions.

32
Q

Jill was resuscitated from cardiac arrest and complains of involuntary muscle contractions and leg cramps. What medication and how much would you administer?

A

10 ml of 10% Calcium Gluconate

33
Q

In an emergency setting, a patient is experiencing a swollen tongue with difficulty breathing, urticaria and pruritis. What medication would be given after epinephrine as a second line treatment?

A

Chlorpheniramine/ pirton 10 mg/ml

34

A

36
Q

Antidote for Dilantin?

A

Valium, hynoval

37
Q

Patient has a NA+ level of 158, 3+ pitting edema and ascites. What is the best diuretic to give and why?

A

Furosemide (Lasix) because it is a loop diuretic which means it inhibits the reabsorption of sodium.

38
Q

Part 1) Marcia has an ECG of ventricular tachycardia. She goes into cardiac arrest on MICU and no amiodarone is available. The doctor orders Lidocaine 142 mg IV. She weighs 230 Ibs. Is this dose safe and why?

Part 2) He orders a second dose of 71 mg IV in 5 mins. Is this dose safe and why?

A

Part 1) Convert = 230 / 2.2 = 104 .5 kg
Dose for Cardiac Arrest (VT/VF) = 1 - 1.5 mg/kg IV
Safe dose = 104.5 x 1 = 104.5 mg IV
= 104 x 1.5 = 156 mg IV
Patient’s dose is safe because it falls in the range of 104 - 156 mg IV

Part 3) Safe dose is 1/2 of first dose in 5 - 10 minutes. 142/2 = 71 mg IV so the dose is safe.

39
Q

Part 1) Kate has a wide complex tachycardia with pulse. No amiodarone is available. The doctor orders Lidocaine 98 mg IV. She weighs 68 kg. Is this dose safe and why?

Part 2) He orders a second dose of 49 mg IV in 10 mins. Is this dose safe and why?

A

Part 1) Dose for Wide Complex Tachycardia =
0.5 - 1.5 mg/ kg IV
Safe dose = 68 kg x 0.5 = 34 mg
= 68 kg x 1.5 = 102 mg
Patient’s dose as in falls in the range of 34 - 102 mg IV

Part 2) Safe dose is 1/2 of first dose in 5-10 minutes. 98/2 = 49 mg IV so the dose is safe.
