Nokea
A client is brought to the emergency department via rescue squad with suspicion of cardiogenic pulmonary edema. What complication(s) should the nurse monitor for? Select all that apply.
- A. Nausea and vomiting
- B. Pulmonary embolism
- C. Cardiac arrhythmias
- D. Respiratory arrest
- E. Cardiac arrest
Correct Answer: C,D,E
Rationale: Pulmonary edema is fluid accumulation in the lungs, which interferes with gas exchange in the alveoli. It represents an acute emergency and is a frequent complication of left-sided heart failure. Cardiac arrhythmias and cardiac or respiratory arrest are associated complications. Nausea and vomiting are not complications but are symptoms of many disorders. The client is not at increased risk for the development of pulmonary embolism with pulmonary edema.

The nurse is preparing to administer digoxin to a client with heart failure. The nurse obtains an apical pulse rate for 1 minute and determines a rate of 52 beats/minute. What is the first action by the nurse?
- A. Administer the medication and inform the charge nurse about the rate.
- B. Withhold the medication and notify the health care provider of the heart rate.
- C. Administer atropine to speed the heart rate and then administer the digoxin.
- D. Administer the medications and then notify the health care provider.
Correct Answer: B
Rationale: Digitalis drugs are withheld if the heart rate is less than 60 or more than 120 beats/minute until a health care provider is consulted. The other choices would have the nurse administer the drug, which would not be the standard of practice.
What disease process(es) contributes to chronic heart failure? Select all that apply.
- A. Tachyarrhythmias
- B. Valvular disease
- C. Pancreatic disease
- D. Renal failure
- E. Pulmonary insufficiency
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.
The nurse is preparing to administer furosemide to a client with severe heart failure. What lab study should be of most concern for this client while taking furosemide?
- A. BNP of 100
- B. Sodium level of 135
- C. Hemoglobin of 12
- D. Potassium level of 3.1
Correct Answer: D
Rationale: Severe heart failure usually requires a loop diuretic such as furosemide (Lasix). These drugs increase sodium and therefore water excretion, but they also increase potassium excretion. If a client becomes hypokalemic, digitalis toxicity is more likely. The BNP does not demonstrate a severe heart failure. Sodium level of 135 is within normal range, as is the hemoglobin level.
The nurse documents pitting edema in the bilateral lower extremities of the client. What does this documentation mean?
- A. There is excess fluid volume in the interstitial space in areas affected by gravity.
- B. There is excess fluid volume in the venous system of the lower extremities.
- C. There is excess fluid volume in the arterial system of the lower extremities.
- D. There is excess fluid volume in the hepatic system.
Correct Answer: A
Rationale: Dependent pitting edema (excess fluid volume in the interstitial space in body areas affected by gravity) in the feet and ankles can be observed. This type of edema may seem to disappear overnight but really is temporarily redistributed by gravity to other tissues, such as the sacral area. The other options are not descriptive of pitting edema.
A client is admitted to the hospital with a diagnosis of heart failure, and the health care provider prescribes a BNP level. What results would indicate to the nurse that the client is in moderate heart failure?
- A. 120 pg/mL
- B. 400 pg/mL
- C. 780 pg/mL
- D. 980 pg/mL
Correct Answer: C
Rationale: The result of 780 pg/mL indicates that the client has moderate heart failure, 120 pg/mL indicates that the client has heart failure present, 400 pg/mL indicates that the client has mild heart failure, and 980 pg/mL indicates that the client is in severe heart failure.
