A nurse is teaching a class about administering IV fluids to treat dehydration. The nurse should include in the teaching that which of the following laboratory values indicates effective treatment of dehydration?

Serum osmolarity 310 mOsm/L

Serum hematocrit 55%

Urine specific gravity 1.020

BUN 28 mg/dL

Answer and Explanation

The Correct Answer is C

Choice A Reason:
Serum osmolarity 310 mOsm/L is incorrect. Serum osmolarity measures the concentration of particles in the blood. While an elevated serum osmolarity might indicate dehydration, it's not a direct indicator of the effectiveness of treatment. It signifies the concentration of solutes in the blood rather than reflecting hydration improvement after treatment.
Choice B Reason:
Serum hematocrit 55%m is incorrect. Elevated hematocrit levels can occur in dehydration because of hemoconcentration (an increase in the concentration of red blood cells due to reduced fluid volume). However, similar to serum osmolarity, while it can indicate dehydration, it doesn't specifically reflect the effectiveness of treatment.
To determine effective treatment of dehydration, the nurse should consider the laboratory values that reflect hydration status:
Choice C Reason:
Urine specific gravity 1.020 is correct. Urine specific gravity measures the concentration of solutes in the urine, indicating the kidneys' ability to concentrate urine. A higher specific gravity (typically above 1.020) suggests more concentrated urine, which can indicate dehydration. As hydration improves, the urine becomes less concentrated, so a decrease in urine specific gravity toward the normal range (around 1.010-1.020) indicates effective rehydration and improved kidney function in retaining fluids.
Choice D Reason:
BUN 28 mg/dL is incorrect. Blood urea nitrogen (BUN) levels can also rise in dehydration due to reduced kidney perfusion. However, like serum osmolarity and hematocrit, while it can indicate dehydration, it doesn't directly show the effectiveness of treatment or the improvement in hydration status after treatment.

Correct Answer is C

Explanation

Choice A Reason:
Weight gain of 0.7 kg (1.5 lb) in 24 hours is not recommendable. While sudden weight gain can indicate fluid retention, it is not a direct contraindication for administering digoxin. However, it might indicate worsening heart failure, which needs attention, but it doesn't specifically necessitate withholding digoxin.
Choice B Reason:
Urinary output 30 mL/hr is not recommendable. A low urinary output might indicate decreased kidney perfusion or renal issues. While monitoring urinary output is important, it is not a direct reason to withhold digoxin unless it's coupled with severe renal impairment or an acute kidney injury.
For a client receiving digoxin, certain findings would warrant withholding the medication due to potential complications. Among the options provided:
Choice C Reason:
Pulse rate 56/min is the correct recommendation. A low pulse rate (bradycardia), especially below 60 beats per minute, is a reason to withhold digoxin. Digoxin can further decrease the heart rate, potentially leading to excessive bradycardia or heart block. The nurse should hold the medication and consult with the healthcare provider to determine the appropriate action.
Choice D Reason:
BP 160/90 mm Hg is not recommendable. Elevated blood pressure alone is not a direct contraindication for administering digoxin to a patient with heart failure. Digoxin is not primarily used for controlling blood pressure; its use is more focused on managing heart rate and contractility in heart failure patients.

A. A client received 0900 medications at 0930. B. A client who has asthma was administered tiotropium via inhalation. C. A client received a blood transfusion with dextrose 5% in water. D. A client received an infusion of lipids through a central line.
