Chapter 24: Heart Failure Drugs Test, Pharmacology for Nurses: Practical Applications
The key terms in this Pharmacology course include Heart Failure Drugs, Intravenous Line, Pharmacology, Digoxin Elixir, Micrograms to Milligrams, Intravenous Digitalis, Negative Chronotropic Effect, Patient, Nurse, AHA Guidelines, First Line Therapy, left Ventricular Ejection Fraction, left Sided Heart Failure, Atenolol, Beta Blockers, Infusion of Milrinone (Primacor), Intravenous Dose of Furosemide (Lasix)
The medication order for a 5-year-old child reads, “Give digoxin elixir, 15 mcg/kg, PO now.” Convert the 15 micrograms to milligrams. __
Correct Answer
0.015 mg
1000 mcg:1 mg :: 15 mcg:x mg.
(1000 × x) = (1 × 15); 1000x = 15; x = 15; 15 ÷ 1000 = 0.015 mg.
While assessing a patient who is receiving intravenous digitalis, the nurse recognizes that the drug has a negative chronotropic effect. How would this drug effect be evident in the patient?
Decreased ectopic beats
Decreased heart rate
Decreased conduction
Decreased blood pressure
A negative chronotropic effect results in a decreased heart rate; this is one effect of cardiac glycosides. The other options are incorrect.
According to the latest AHA guidelines which drugs are recommended for first line therapy in the treatment of Heart Failure ? Select all that apply.
a. Enalapril
b. Losartan
c. Hydrochlorothiazide
d. Carvedilol
The normal value for the left ventricular ejection fraction is 50 %.
True
False
Symptoms of left sided heart failure include all of the following except ?
a. moon face
b. peripheral edema
c. dyspnea
d. coughing
In some cases, Atenolol, a beta blockers can worsen symptoms of heart failure.
True
False
A patient is in the intensive care unit and receiving an infusion of milrinone (Primacor) for severe heart failure. The prescriber has written an order for an intravenous dose of furosemide (Lasix). How will the nurse give this drug?
Administer the furosemide in a separate intravenous line.
Infuse the drug into the same intravenous line as the milrinone.
Stop the milrinone, flush the line, and then administer the furosemide.
Notify the prescriber that the furosemide cannot be given at this time.
Furosemide must not be injected into an intravenous line with milrinone because it will precipitate immediately. The infusion must not be stopped because of the patient’s condition. A separate line will be needed. The other options are incorrect.
