A

end-diastolic volume,

BP,

HR,

28
Q

This medication

Can cause cyanide toxicity

(by releasing cyanide)

A

Nitroprusside

29
Q

This medication

prevents degradation of natriuretic peptides:

angiotensin II & substanceP

→ ↑vasodilation, ↓ECF volume

A

Sacubitril

30
Q

This medication is

Used in combination with

valsartan (an ARB)

to treat

HFrEF.

A

Sacubitril

31
Q

This medication is

contraindicated with ACE inhibitors due to angioedema.

A

Sacubitril

32
Q

↓HR

A

Digoxin

35
Q

HF ( to ↑ contractility)

Atrial fibrillation ( to ↓ conduction at AV node and depression of SA node)

A

Digoxin

36
Q

The following is the management for what medication toxicity?

  • Give anti-[Medication] Fab fragments
  • Start Mg2+ infusion
  • Slowly normalize K+ (via Insulin + D5W)

A

Digoxin

38
Q

Hyperkalemia indicates a poor prognosis when taking what medication?

DIgoxin

39
Q

Digoxin functions via binding to open ____ binding sites of which transporter?

(permissive for drug binding at ),

drugs that displace drug from tissue-binding sites,

(eg: verapamil, amiodarone, quinidine).

A

K+ binding sites on the

Na+/K+ ATPase

(hence hypokalemia while on Digoxin increases risk for toxicity which results in hyperkalemia – Note digoxin is sometimes used with anti-hypertensive medication that causes hypokalemia)
