The nurse is caring for a patient in the intensive care unit with acute decompensated heart failure (ADHF) who has symptoms of severe dyspnea and is anxious, tachypneic, and tachycardic. All these medications have been prescribed for the patient. Which of the following actions should the nurse implement first?
- A. Give IV diazepam 2.5 mg
- B. Administer IV morphine sulphate 2 mg
- C. Increase nitroglycerin infusion by 5 mcg/min.
- D. Increase dopamine infusion by 2 mcg/kg/min.
Correct Answer: B
Rationale: Morphine improves alveolar gas exchange, improves cardiac output by reducing ventricular preload and afterload, decreases anxiety, and assists in reducing the subjective feeling of dyspnea. Diazepam may decrease patient anxiety, but it will not improve the cardiac output or gas exchange. Increasing the dopamine may improve cardiac output, but it also will increase the heart rate and myocardial oxygen consumption. Nitroglycerin will improve cardiac output and may be appropriate for this patient, but it will not directly reduce anxiety and will not act as quickly as morphine to decrease dyspnea.

The nurse is caring for a patient with chronic heart failure. Which of the following conditions is a cause of chronic heart disease?
- A. Dysrhythmias
- B. Pulmonary embolus
- C. Myocarditis
- D. Congenital heart disease
Correct Answer: D
Rationale: Congenital heart disease is a cause of chronic heart failure. Dysrhythmias, pulmonary embolus, and myocarditis are causes of acute heart failure.
Which of the following patients is less likely to enroll in a cardiac rehabilitation program?
- A. A 64-year-old male who has diabetes
- B. A 51-year-old male who has a same-sex partner
- C. A 52-year-old single female
- D. A 39-year-old male with two children
Correct Answer: C
Rationale: Women are 36% less likely to enroll in cardiac rehabilitation programs.
Which assessment finding in a patient admitted with chronic heart failure requires the most rapid action by the nurse?
- A. Oxygen saturation of 88%
- B. Weight gain of 1 kg
- C. Apical pulse rate of 106 beats/minute
- D. Urine output of 50 ml over 2 hours
Correct Answer: A
Rationale: In a person with HF, oxygen saturation of the blood may be reduced because the blood is not adequately oxygenated in the lungs. Administration of oxygen, if the O2 saturation is less than 90%, can improve tissue oxygenation. Thus, appropriate use of oxygen therapy helps relieve dyspnea and fatigue. An increase in apical pulse rate, 1-kg weight gain, and decreases in urine output also indicate worsening heart failure and require rapid nursing actions, but the low oxygen saturation rate requires the most immediate nursing action.
The nurse is caring for an older-adult patient with heart failure and learns that the patient lives alone and sometimes confuses the 'water pill' with the 'heart pill.' When planning for the patient's discharge the nurse will facilitate which of the following actions?
- A. Transfer to a dementia care service
- B. Referral to a home health care agency
- C. Placement in a long-term care facility
- D. Arrangements for around-the-clock care
Correct Answer: B
Rationale: The data about the patient suggest that assistance in developing a system for taking medications correctly at home is needed. A home health nurse will assess the patient's home situation and help the patient develop a method for taking the two medications as directed. There is no evidence that the patient requires services such as dementia care, long-term care, or around-the-clock home care.
The nurse is conducting a health history on a patient with heart failure. Which of the following conditions in the patient's health history is a precipitating cause of heart failure?
- A. Hyperthyroidism
- B. Anemia
- C. Hypovolemia
- D. Diabetes
Correct Answer: B
Rationale: Anemia is a precipitating cause of heart failure. Also, hypovolemia and hypothyroidism are precipitating causes. Diabetes is not a precipitating cause of heart failure.
