Vitamin C can be found in which of the following sources?

A. Notify the charge nurse that patients may have received inappropriate medication dosages.
Jumping to conclusions about inappropriate dosages without first investigating the rationale for the dosing is premature and could cause unnecessary alarm.

B. Evaluate the laboratory values of each patient to determine liver and kidney function as a possible reason for decreased dosages. Lower dosages are often prescribed for older adults due to decreased liver and kidney function, which can affect drug metabolism and excretion. Evaluating lab values ensures that these dosages are appropriate and safe.

C. Do not worry about the discrepancy because this is not the nurse's unit.
Ignoring the discrepancy is not appropriate, as it’s important for all nurses to advocate for patient safety, regardless of the unit.

D. Call the nursing supervisor to investigate the nurse's concerns.
The nursing supervisor may need to be involved, but the first step is to review the relevant clinical data (lab values) to assess the situation.

A. Checking the label before taking the medication out of the cabinet, pouring the medication, and placing the bottle back in the cabinet. This option does not follow the "three checks" principle effectively. The label should also be checked after pouring and before administering the medication to ensure accuracy.

B. Checking the label while removing the bottle from the cabinet, after pouring the dose of medication, and while replacing the bottle in the cabinet. This option correctly follows the "three checks" principle: when removing the medication from the cabinet, after pouring the dose, and when replacing the bottle. This ensures that the right medication is given in the correct dose.

C. Checking the label after removing the bottle from the cabinet and pouring the dose of medication and before closing the cabinet door. This option misses the second check before administering the medication, which is essential to ensure the correct drug and dosage.

D. Checking the label before leaving the medication room. Checking the label before leaving the medication room does not ensure that the correct medication and dosage are being administered at the bedside.
