A nurse is monitoring the cardiac output of a client who has left-sided heart failure using pulse pressure analysis. Which of the following findings can compromise the readings?
The client is experiencing premature atrial contractions.
The client has bilateral wheezes.
The client has a decreased oxygen saturation level.
The client has lower leg edema.
The Correct Answer is A
A. The client is experiencing premature atrial contractions is correct. Premature atrial contractions can interfere with pulse pressure analysis and affect the accuracy of cardiac output measurements.
B. The client has bilateral wheezes is incorrect. Wheezes affect lung function, not directly the accuracy of pulse pressure analysis for cardiac output.
C. The client has a decreased oxygen saturation level is incorrect. While it is a concern, it does not compromise pulse pressure readings directly.
D. The client has lower leg edema is incorrect. Edema affects peripheral circulation but does not directly compromise pulse pressure measurements for cardiac output.

Explanation
- Administer furosemide: The patient has signs of pulmonary edema which needs to be managed.
- Administer ordered Epinephrine drip: Epinephrine is crucial for managing hemodynamic instability.
- Insert an indwelling urinary catheter: Monitoring urine output helps assess kidney function and fluid balance.
- Administer ordered low dose dopamine: Useful for maintaining renal perfusion and blood pressure.
- Administered 0.9% NS 500 mL bolus: Helps address hypotension and volume deficit.
- Administer ordered nitroglycerin: Not needed in this acute post-arrest phase unless specifically indicated for managing ongoing angina or heart failure symptoms.
Correct Answer is B
Explanation
A. Bounding peripheral pulses are more associated with fluid overload, not diabetes insipidus.
B. Tachycardia can occur in diabetes insipidus due to dehydration and fluid loss.
C. Hypertension is not a typical finding; clients with diabetes insipidus often have low blood pressure due to fluid loss.
D. Hyperglycemia is associated with diabetes mellitus, not diabetes insipidus.
