Final answer:
Factors that could prevent surgery for John are a high blood pressure of 162/101 mm Hg, daily use of aspirin, and a fever of 100.2°F, indicating potential underlying issues such as increased bleeding risk and infection.
Step-by-step explanation:
Assessment findings that could prevent John from proceeding with surgery include:
- BP 162/101 mm Hg - This indicates hypertension, which can be a significant risk factor for cardiovascular complications during or after surgery.
- Taking aspirin daily - Aspirin is an antiplatelet agent which can increase the risk of bleeding. Typically, it is recommended to stop aspirin several days before surgery to reduce this risk.
- Temperature 100.2°F - A fever may indicate an infection, and operating on a patient with an active infection can increase the risk of postoperative complications.
The other findings, such as a heart rate of 88 beats/min and a dry, nonproductive cough, may not necessarily prevent surgery but they should still be evaluated in the context of the patient's overall health.
