In preparing for a hemodynamic assessment, the nurse identifies which of the following to have the greatest negative effect on accuracy of the measurements?
1. the measurements are taken at end expiration
2. the patient is positioned supine at a 45-degree elevation
3. the patient is positioned in a side-lying position
4. inotropic medications are being administered concurrently
3
Rationale: Research has shown that hemodynamic measurements are accurate when the head of the bed is elevated between 0 and 60 degrees, as long as the patient is supine. A side-lying position will affect the accuracy of the readings. Measurements should normally be taken at end expiration. Positions between 0 and 60 degrees will not affect accuracy as long as the patient is supine. The rationale for measurements is to determine the effectiveness of therapy, including administration of inotropic medications. Concurrent administration will not negatively affect these measurements.
