NURSING CONSIDERATIONS FOR HEART FAILURE
MANAGEMENT
Understanding Heart Failure and Medications
Digitalis Toxicity Symptoms
Digitalis toxicity can manifest through various symptoms,
including anorexia, nausea, vomiting, blurred or yellow
vision, and cardiac dysrhythmias.
Anorexia and nausea are particularly concerning as they are
early signs of toxicity, prompting the nurse to notify the
healthcare provider.
Other symptoms like blurred vision can indicate severe
toxicity, necessitating immediate medical intervention.
Case Study: A patient on digoxin who reports nausea and
visual disturbances should be assessed for toxicity and have
their digoxin levels checked.
Historical Context: Digitalis has been used for centuries to
treat heart conditions, but its narrow therapeutic index
requires careful monitoring.
Laboratory Considerations for Digoxin Administration
Normal potassium levels range from 3.5 to 5.0 mEq/L;
levels above this can increase the risk of digoxin toxicity.
, In this case, the patient has a potassium level of 5.6 mEq/L,
indicating hyperkalemia, which is a contraindication for
administering digoxin.
The nurse should withhold the medication and report the
potassium level to the healthcare provider for further
management.
Example: If a patient presents with hyperkalemia, the
healthcare provider may order potassium-lowering
treatments before resuming digoxin.
Importance of Monitoring: Regular monitoring of
electrolytes is crucial in patients receiving digoxin to
prevent toxicity.
Nursing Interventions and Patient Management
Priority Assessments for Heart Failure Treatments
When administering IV nesiritide, the priority assessment is
blood pressure due to the risk of hypotension, a common
side effect of this medication.
Other assessments like urine output and lung sounds are
also important but secondary to blood pressure monitoring.
Example: A patient receiving nesiritide should have their
blood pressure monitored frequently to detect any
significant drops.
Historical Context: Nesiritide is a recombinant form of B-
type natriuretic peptide used in acute heart failure
management, emphasizing the need for careful monitoring.
