Chapter 28 : Caring for Clients With Heart Failure Questions
Question 1 of 5
A client diagnosed with pulmonary edema has a PaCO2 of 72 mm Hg and an oxygen saturation of 84%. What method of oxygen delivery would best meet the needs of this client?
Correct Answer: A
Rationale: The client's respiratory status is severely compromised and has developed signs of respiratory failure. When respiratory failure occurs, the client is intubated and oxygen is administered under continuous positive airway pressure or with mechanical ventilation with positive end-expiratory pressure. A face mask, cannula, or Venturi mask will not deliver the concentration or ventilatory support that an endotracheal tube with mechanical ventilation will provide.
Question 2 of 5
A client develops cardiogenic pulmonary edema and is extremely apprehensive. What medication can the nurse administer with a health care provider's prescription that will relieve anxiety and slow respiratory rate?
Correct Answer: D
Rationale: Morphine seems to help relieve respiratory symptoms by depressing higher cerebral centers, thus relieving anxiety and slowing respiratory rate. Morphine also promotes muscle relaxation and reduces the work of breathing. Furosemide is a loop diuretic and will decrease fluid accumulation but will not reduce anxiety. Nitroglycerin will promote smooth muscle relaxation in the vessel walls and will relieve pain but not reduce anxiety. Dopamine is an inotrope that will increase the force of ventricular contraction but will not alleviate anxiety.
Question 3 of 5
A client is taking furosemide for the treatment of heart failure. What food should the nurse suggest that is rich in potassium?
Correct Answer: B
Rationale: Peanut butter is rich in potassium. Pasta, coffee, and angel food cake are low potassium items.
Question 4 of 5
The nurse instructs the client with heart failure to check weight at the same time each day using the same scale. When should the client contact the health care provider?
Correct Answer: C
Rationale: Clients should check weight at the same time each day using the same scale and should consult a health care provider if the weight gain is more than 2 pounds in 24 hours. The other options are not correct since there is a variance with weight on a daily basis.
Question 5 of 5
What disease process(es) contributes to chronic heart failure? Select all that apply.
Correct Answer: A,B,D
Rationale: Hypertension, tachyarrhythmias, valvular disease, cardiomyopathy, and renal failure can contribute to chronic heart failure. Pancreatic disease and pulmonary insufficiency do not contribute to chronic heart failure.
