The nurse is caring for a patient with severe left ventricular dysfunction who has been identified as being at risk for sudden cardiac death. What medical intervention can be performed that may extend the survival of the patient?
- A. Insertion of an implantable cardioverter defibrillator
- B. Insertion of an implantable pacemaker
- C. Administration of a calcium channel blocker
- D. Administration of a beta-blocker
Correct Answer: A
Rationale: In patients with severe left ventricular dysfunction and the possibility of life-threatening dysrhythmias, placement of an implantable cardioverter defibrillator (ICD) can prevent sudden cardiac death and extend survival. A pacemaker, a calcium channel blocker, and a beta-blocker are not medical interventions that may extend the survival of the patient with left ventricular dysfunction.

The nurse is providing patient education prior to a patients discharge home after treatment for HF. The nurse gives the patient a home care checklist as part of the discharge teaching. What should be included on this checklist?
- A. Know how to recognize and prevent orthostatic hypotension
- B. Weigh yourself weekly at a consistent time of day
- C. Measure everything you eat and drink until otherwise instructed
- D. Limit physical activity to only those tasks that are absolutely necessary
Correct Answer: A
Rationale: Patients with HF should be aware of the risks of orthostatic hypotension. Weight should be measured daily; detailed documentation of all forms of intake is not usually required. Activity should be gradually increased within the parameters of safety and comfort.
An older adult patient with HF is being discharged home on an ACE inhibitor and a loop diuretic. The patients most recent vital signs prior to discharge include oxygen saturation of 93% on room air, heart rate of 81 beats per minute, and blood pressure of 94/59 mm Hg. When planning this patients subsequent care, what nursing diagnosis should be identified?
- A. Risk for ineffective tissue perfusion related to dysrhythmia
- B. Risk for fluid volume excess related to medication regimen
- C. Risk for ineffective breathing pattern related to hypoxia
- D. Risk for falls related to hypotension
Correct Answer: D
Rationale: The combination of low BP, diuretic use, and ACE inhibitor use constitute a risk for falls. There is no evidence, or heightened risk, of dysrhythmia. The patients medications create a risk for fluid deficit, not fluid excess. Hypoxia is a risk for all patients with HF, but this is not in evidence for this patient at this time.
The nurse is caring for a 68-year-old patient the nurse suspects has digoxin toxicity. In addition to physical assessment, the nurse should collect what assessment datum?
- A. Skin turgor
- B. Potassium level
- C. White blood cell count
- D. Peripheral pulses
Correct Answer: B
Rationale: The serum potassium level is monitored because the effect of digoxin is enhanced in the presence of hypokalemia and digoxin toxicity may occur. Skin turgor, white cell levels, and peripheral pulses are not normally affected in cases of digitalis toxicity.
The nurse is reviewing the medication administration record of a patient diagnosed with systolic HF. What medication should the nurse anticipate administering to this patient?
- A. A beta-adrenergic blocker
- B. An antiplatelet aggregator
- C. A calcium channel blocker
- D. A nonsteroidal anti-inflammatory drug (NSAID)
Correct Answer: A
Rationale: Several medications are routinely prescribed for systolic HF, including ACE inhibitors, beta-blockers, diuretics, and digitalis. Calcium channel blockers, antiplatelet aggregators, and NSAIDs are not commonly prescribed.
A patient with a diagnosis of HF is started on a beta-blocker. What is the nurses priority role during gradual increases in the patients dose?
- A. Educating the patient that symptom relief may not occur for several weeks
- B. Stressing that symptom relief may take up to 4 months to occur
- C. Making adjustments to each days dose based on the blood pressure trends
- D. Educating the patient about the potential changes in LOC that may result from the drug
Correct Answer: A
Rationale: An important nursing role during titration is educating the patient about the potential worsening of symptoms during the early phase of treatment and stressing that improvement may take several weeks. Relief does not take 4 months, however. The nurse monitors blood pressure, but changes are not made based on short-term assessment results. Beta-blockers rarely affect LOC.
