A nurse is reviewing urinary laboratory results. Which findings should prompt the nurse to follow up?
Specific gravity of 1.036.
pH of 6.4.
Presence of proteinuria.
Presence of hematuria.
Correct Answer : A,C
Choice A rationale
A specific gravity of 1.036 is higher than the normal range of 1.005 to 1.030345. This could indicate dehydration or other conditions that cause the urine to be more concentrated. This finding should prompt the nurse to follow up.
Choice B rationale
A pH of 6.4 is within the normal range for urine, which is typically between 4.6 and 8.03. Therefore, this finding would not necessarily require follow-up.
Choice C rationale
The presence of proteinuria (protein in the urine) is abnormal and could indicate kidney disease or other serious health conditions. This finding should prompt the nurse to follow up.
Choice D rationale
The presence of hematuria (blood in the urine) can be a sign of several conditions, including urinary tract infections, kidney stones, or bladder infections. However, without more information, it’s not clear whether this finding alone should prompt the nurse to follow up.

Correct Answer is B
Explanation
Choice A rationale
0.9% sodium chloride, also known as normal saline, is an isotonic solution that is commonly used for hydration and to replace lost fluids. However, it does not provide any calories or nutrients, which are necessary for patients receiving TPN1.
Choice B rationale
Dextrose 10% in water (D10W) is the recommended solution to administer until the next TPN solution is available. This is a hypertonic fluid that provides dextrose to the patient, helping to maintain their blood glucose levels and reducing the risk of hypoglycemia.
Choice C rationale
3% sodium chloride is a hypertonic saline solution that is typically used to treat patients with severe hyponatremia (low sodium levels). It is not suitable as a replacement for TPN as it does not provide the necessary nutrients and can lead to hypernatremia (high sodium levels) if used inappropriately.
Choice D rationale
Lactated Ringer’s solution is an isotonic solution that is commonly used for fluid resuscitation in patients with significant fluid loss. While it does contain multiple electrolytes that mimic those found in plasma, it does not provide any calories or nutrients, making it unsuitable as a replacement for TPN1.
Correct Answer is ["31"]
Explanation
Step 1: Calculate the total volume to be infused. Total volume = 250 mL.
Step 2: Calculate the total time for the infusion in minutes. Total time = 2 hours × 60 minutes/hour = 120 minutes.
Step 3: Calculate the flow rate in mL/min. Flow rate = Total volume ÷ Total time = 250 mL ÷ 120 min = 2.08 mL/min.
Step 4: Calculate the flow rate in drops/min. Flow rate = 2.08 mL/min × 15 drops/mL = 31.25 drops/min. So, the nurse should adjust the flow rate to deliver approximately 31 drops per minute.
