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.

Correct Answer is ["100"]
Explanation
- Total volume to infuse: 200 mL
- Time for infusion: 2 hours
- The IV pump rate is calculated as: (Total Volume / Time) = Rate
- So, the calculation would be: (200 mL / 2 hr) = 100 mL/hr
- The nurse should set the IV pump to deliver 100 mL/hr.

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A,B"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A,B"}}
Explanation
1. Provider Consult
Angina: Not typically associated with immediate provider consultation.
MI: Requires immediate consultation for treatment decisions, such as medication or interventions.
2. Client's Initial Report of Manifestations
Angina: Can present with discomfort or pressure that is transient and relieved by rest or nitroglycerin.
MI: Can present similarly but is often more severe and sustained; discomfort may be a precursor to a myocardial infarction.
3. Treadmill Stress Test
Angina: Often used to provoke symptoms under controlled conditions for diagnosis.
MI: Not used during an acute phase; rather, diagnostics are performed through EKG and cardiac enzyme tests.
4. Result of Nitroglycerin Therapy
Angina: Relief from nitroglycerin indicates angina.
MI: Nitroglycerin might not provide relief; other treatments and diagnostics are needed.
5. 12 Lead EKG Report
Angina: ST depression and T-wave inversion can occur with angina.
MI: These EKG changes can indicate ischemia, which could be part of an acute MI if accompanied by other severe symptoms or in the presence of persistent symptoms.
