A client with fluid volume overload is admitted to the hospital for diuresis. Which assessment should the nurse perform to evaluate the client's fluid balance?

A. Advise the UAP to hold the thermometer securely in place for a full three minutes is incorrect because tympanic thermometers provide quick readings, typically within a few seconds, and do not require prolonged placement.

B. Use positive reinforcement to affirm that the procedure is being performed correctly is the correct action. For adult clients, the auricle should be pulled up and back to straighten the ear canal for accurate tympanic temperature measurement. Positive reinforcement supports the UAP's learning and confidence.

C. Demonstrate the correct technique for pulling the client's auricle down and back is incorrect for adult clients. Pulling the auricle down and back is appropriate for children under 3 years old, not adults.

D. Remind the UAP to lubricate the thermometer before gently inserting in the ear is not appropriate. Tympanic thermometers do not require lubrication, as they are designed for non-invasive and quick use.

A. Use at least 2 client identifiers before administering a dose – This is a critical step in preventing medication errors, but it would not have prevented the error in this scenario. The issue was with the dosage of the medication, not the identification of the client.
B. Document all medication as soon as it is given – While documentation is important for patient safety, it does not directly address the error of giving the wrong dose. Proper calculation and verification of the dose before administration are more effective in preventing this type of error.
C. Question unusually large or small doses – This is a key technique for preventing medication errors. The nurse should have questioned the unusually large dose of potassium, which was not calculated based on the client's weight and the prescribed amount. This would have alerted the nurse to the error before administering the medication.
D. Double check the dosage of high-risk medications with another nurse – Potassium is considered a high-risk medication, and double-checking the dosage with another nurse would have been an effective safety measure. This technique helps to catch errors in dosage calculations, especially with medications that have narrow therapeutic windows like potassium.
E. Involve and educate clients in medication administration – While involving and educating clients is important for overall safety and understanding, it is not a technique that would have helped prevent this particular medication error. The error was related to the nurse’s calculation and administration of the dose, not the client's involvement.
