A nurse is calculating the total fluid intake for a patient over a 4-hour period.

The patient consumed 1 cup of coffee, 4 oz of orange juice, 3 oz of water, 1 cup of flavored gelatin, 1 cup of tea, 5 oz of broth, and 3 oz of water.

How many mL of intake should the nurse record on the patient’s chart?

Step 1: Convert All Fluid Intake to Milliliters (mL)

To accurately record the patient's fluid intake, first, convert each fluid measurement to milliliters:

• 1 cup of coffee = 240 mL
• 4 oz of orange juice = 118.3 mL
• 3 oz of water = 88.7 mL
• 1 cup of flavored gelatin = 236.6 mL
• 1 cup of tea = 240 mL
• 5 oz of broth = 147.9 mL
• 3 oz of water (another serving) = 88.7 mL

Step 2: Calculate Total Fluid Intake

Add all the converted fluid amounts together:

• Total fluid intake = 240 mL (coffee) + 118.3 mL (orange juice) + 88.7 mL (water) + 236.6 mL (gelatin) + 240 mL (tea) + 147.9 mL (broth) + 88.7 mL (water) = 1,160.2 mL

Step 3: Round to the Nearest Whole Number

Round the total to the nearest whole number:

• Rounded total = 1,160 mL

The nurse should record 1,160 mL on the patient’s chart.

Choice A rationale

The glomerular filtration rate (GFR) does not recover during the oliguric phase of acute kidney injury (AKI). Recovery of GFR typically occurs during the recovery phase.

Choice B rationale

During the oliguric phase of AKI, urine output is typically less than 400 mL per 24 hours.

Choice C rationale

Renal function is not reestablished during the oliguric phase of AKI. This typically occurs during the recovery phase.

Choice D rationale

Blood urea nitrogen (BUN) and creatinine levels do not decrease during the oliguric phase of AKI. These levels typically increase due to decreased kidney function.
