The client is prescribed a beta-blocker as adjunct therapy to treatment
of heart failure. The nurse recognizes that beta blockers act by
Increasing contractility and cardiac output.
Decreasing preload.
Slowing the heart and decreasing afterload.
Decreasing peripheral resistance - ANSWER Slowing the heart and
decreasing afterload.
Rationale: Beta-blockers improve symptoms of HF by slowing heart rate
and decreasing blood pressure. The decreased afterload causes
decreased workload on the heart.
The nurse includes the definition of HF in the teaching plan for the
client. An accurate description of the mechanism of HF is that [Hint]
there is too much fluid in the heart.
, the heart cannot get oxygen.
the heart is unable to pump effectively.
there is too much fluid in the lungs. - ANSWER the heart is unable to
pump effectively.
Lisinopril (Prinivil) is part of the treatment regimen for a client with HF.
The nurse monitors the client for which electrolyte imbalance of this
drug?
Hyponatremia
Hyperkalemia
Hypokalemia
Hypernatremia - ANSWER Hyperkalemia
Rationale: ACE inhibitors block aldosterone secretion, which results in
sodium loss and potassium retention. Hyperkalemia may occur,
especially when the drug is taken concurrently with potassium-sparing
diuretics.
When caring for a client receiving triamterene (Dyrenium), the nurse
places priority on which nursing intervention?
Monitor electrolytes for hyperkalemia.
