rate of contraction

Question 24

Dromotropic

Answer 24

the conductivity

Question 25

Answer 29

Elderly, HF, Dehydration, Electrolyte imbalances (Hypokalemia & Hypomagnesemia), Kidney Disease, Drug-Drug interaction

Question 30

Pulse to be taken daily prior to administering dose - IF <60 BPM or >100BPM What should you do?

Answer 30

Do not give medication, hold med, call HCP

Question 31

Should you monitor Potassium Levels for Digoxin?

Answer 31

Yes, because Digoxin decreases the levels of potassium

Question 32

Should you give Digoxtin if – A person with Dig leves of 3.2?

Answer 32

No - Normal is 0.5-2ng/mL

Question 33

Should you give Digoxtin if – If Apical Pulse of 57

Answer 33

Wait a little and retake it or look at patters from past days

Question 34

Should you give Digoxtin if – Urine output of 200cc for 24 hrs?

Answer 34

It does have some diuretic effect, but there is very poor renal function – would hold because too low urine output

Question 35

Should you give Digoxtin if apical pulse of 90?

Answer 35

Yes

Question 36

Should you give Digoxtin if potassium level of 2.2

Answer 36

nope, hypokalemia is risk for dig toxicity (normal levels is 3.5-4.5)

Question 37

Should you give Digoxtin if the patient says your face looks a “bit green”?

Answer 37

Nope this is a sign of Dig toxicity
