Which of the following describes oral glucose precautions?

• A. It should be given only if blood glucose is below 60 mg/dL
• B. It is contraindicated in elderly patients
• C. Nausea
• D. Pregnancy category A; effects delayed in elderly or poor circulation; administer based on signs if no glucose reading available

Answer: (D)

Oral glucose precautions hinge on three practical ideas: safety in populations, how quickly it may work, and what to do when a glucose reading isn’t yet available. It is appropriate to use in pregnancy (pregnancy category A), so pregnancy is not a barrier to administration. The absorption of oral glucose can be slower in the elderly or in people with poor peripheral circulation, so you may see a delayed effect and should monitor the patient for an adequate response. If the patient is conscious and showing signs of hypoglycemia, you can administer oral glucose based on those signs even if you don’t yet have a glucose reading, then recheck soon after. This approach reflects treating based on clinical presentation while waiting for or obtaining a measurement. Nausea can occur but by itself doesn’t define the precautions, and saying it’s contraindicated in the elderly or only giving it if glucose is below a fixed threshold doesn’t fit how oral glucose is used in practice.
