A nurse is collecting data for a client who has fluid volume deficit. Which of the following is an expected finding?

Decreased hematocrit

Increased urine ketones

Increased urine specific gravity

Decreased BUN

Answer and Explanation

The Correct Answer is C

A.   Hematocrit measures the percentage of red blood cells in the blood. In fluid volume deficit, there is hemoconcentration due to decreased fluid volume, resulting in an increase in hematocrit rather than a decrease. Therefore, a decreased hematocrit would not be an expected finding in fluid volume deficit.
B.   Urine ketones are typically elevated in conditions where there is increased fat metabolism, such as in diabetic ketoacidosis or starvation. They are not directly related to fluid volume deficit and would not be an expected finding.
C.   Urine specific gravity measures the concentration of solutes in the urine, indicating the kidney's ability to concentrate or dilute urine. In fluid volume deficit, the body conserves water, leading to increased urine concentration and higher urine specific gravity. Therefore, increased urine specific gravity is an expected finding in fluid volume deficit.
D.   BUN is a measure of kidney function and protein metabolism. In fluid volume deficit, there is hemoconcentration due to decreased fluid volume, which can lead to an increase in BUN rather than a decrease. A decreased BUN would not typically be an expected finding in fluid volume deficit.

Correct Answer is ["2"]

Explanation

To administer a dose of 3 mg of dexamethasone when you have tablets of 1.5 mg, you would need to calculate the number of tablets that would equal the total required dose. In this case, since each tablet contains 1.5 mg, you would need two tablets to make up the 3 mg dose.

Therefore, the nurse should administer two tablets of dexamethasone

A. Administer glucagon IM. B. Check the client for a positive Chvostek's sign. C. Request a potassium replacement. D. Discontinue the TPN infusion.

Correct Answer is C

Explanation

A. Glucagon is administered to increase blood glucose levels in hypoglycemic states. However, the client's glucose level is within the normal range (72 mg/dL), so administering glucagon is not appropriate.

B. Chvostek's sign is assessed to detect hypocalcemia, not hypokalemia. It involves tapping the facial nerve anterior to the earlobe and observing for facial muscle contraction. This action is not relevant to the potassium level and is not indicated based on the laboratory findings provided.
C. The client's potassium level of 3.0 mEq/L is below the normal range, indicating hypokalemia. Potassium replacement is essential to prevent complications such as cardiac arrhythmias. The nurse should follow the facility's protocol for administering potassium replacement, which may include adjusting the TPN solution or administering intravenous potassium supplements.
D. Discontinuing the TPN infusion is not warranted based solely on the potassium level. The TPN infusion provides essential nutrition and should not be stopped without addressing the electrolyte imbalance separately.
