The practical nurse (PN) is caring for an infant admitted with vomiting, diarrhea, and dehydration.
The PN weighs the diapers to calculate urinary output.
How many mL of urine output should the PN record for a wet diaper weight of 75 grams compared to the dry diaper weight of 50 grams?
The Correct Answer is ["25"]
Step 1 is: Subtract the dry diaper weight from the wet diaper weight to find the weight of the urine. 75 grams - 50 grams = 25 grams.
Step 2 is: Convert the weight of the urine from grams to milliliters, as 1 gram of urine is approximately equal to 1 mL. 25 grams = 25 mL. The urine output is 25 mL.

Correct Answer is B
Explanation
Choice A rationale
Performing deep tendon reflexes every 4 hours is primarily indicated for clients at risk of magnesium sulfate toxicity, not directly for fetal heart rate decelerations after the peak of contractions. These decelerations suggest uteroplacental insufficiency, where oxygen supply to the fetus is compromised, and magnesium sulfate is used for pre-eclampsia.
Choice B rationale
A left side-lying position alleviates compression of the inferior vena cava and aorta by the gravid uterus, thereby improving uteroplacental blood flow and oxygen delivery to the fetus. This physiological change can often resolve late decelerations, which are indicative of uteroplacental insufficiency due to reduced maternal blood flow.
Choice C rationale
Inserting an indwelling urinary catheter to monitor hourly output is essential for assessing fluid balance and renal perfusion, especially in high-risk pregnancies or those receiving intravenous fluids. However, it does not directly address or correct fetal heart rate decelerations caused by uteroplacental insufficiency.
Choice D rationale
Collecting a urine specimen for electrolytes and protein is a diagnostic measure for conditions like pre-eclampsia, which involves proteinuria and electrolyte imbalances. While important for overall maternal assessment, it does not provide an immediate intervention for late fetal heart rate decelerations.
Correct Answer is ["0.7"]
Explanation
Step 1 is: Convert pounds to kilograms. 58 pounds ÷ 2.2 pounds/kg = 26.36 kg.
Step 2 is: Calculate the total milligrams per dose. 1 mg/kg × 26.36 kg = 26.36 mg.
Step 3 is: Calculate the volume to administer per dose. 26.36 mg ÷ (40 mg/mL) = 0.659 mL.
Step 4 is: Round to the nearest tenth. 0.7 mL.
