Reyno and De Vera: insulin orders, blood-sugar checks, and the nursing record

Facts and context

Teresita Baltazar, who had diabetes, underwent foot debridement. A specialist ordered scheduled insulin only after a random blood-sugar (RBS) test before each injection. Nurse Elsa De Vera gave insulin at 11:30 a.m.; nurse Eleanor Reyno gave another dose at 5:20 p.m. The chart recorded the injections but no RBS test before either one. Teresita later deteriorated and died. Her family sought damages.

Issue

Could the nurses be held liable where the ordered pre-injection tests were not documented, and did the circumstances support an inference of negligence under res ipsa loquitur?

Ruling and doctrine

The Supreme Court affirmed the Court of Appeals’ finding that Reyno and De Vera were jointly and severally liable. It applied res ipsa loquitur to the facts, but it did not rely on the death alone. The physician explained why insulin without a prior RBS test could cause dangerous hypoglycemia; the chart showed two doses without the required tests; and the surrounding records and nurse endorsements did not substantiate the nurses’ assertion that testing had been done. The Court considered the missed condition in the order and the clinical evidence linking it to Teresita’s deterioration. It found no fault in the debridement performed by her physicians on this record.

Practice implications

Parao Law practice guidance

For nurses and treating teams

• Read conditional medication orders as conditions: verify and document the required result before administering a dose. If a result is unavailable, clarify the order rather than silently treating the condition as satisfied.
• Include pending tests and conditional orders in shift endorsements. Record both the test result and the administration time so the next clinician can reconstruct the sequence.
• Escalate deterioration promptly and preserve the original chart. A later assertion that testing occurred may be difficult to establish when the chart records other interventions but omits the disputed test.

For lawyers

• Compare the written order, medication administration record, test results, endorsements, and expert explanation. Identify which clinician had the relevant task at each time.
• The Court used res ipsa on a specific combination of ordered precautions, control, records, and medical testimony. It did not hold that every death after routine care proves nursing negligence.

Limits of the ruling

The case concerned a civil damages claim and its particular record. It is not a universal insulin protocol or a ruling that every missing chart entry proves that a test was never performed. The Court weighed the missing entries with the other evidence.
