A nurse is caring for a client who is receiving IV fluids to correct dehydration. Which of the following laboratory values should indicate to the nurse that the client is effectively responding to treatment?

Urine specific gravity 1.020.

Potassium 5.2 mEq/L.

Hct 6296.

Sodium 165 mEq/L.

Answer and Explanation

The Correct Answer is A

Urine specific gravity 1.020.

Choice A rationale:

Urine specific gravity is a measure of urine concentration, indicating the ability of the kidneys to concentrate or dilute urine. A specific gravity of 1.020 falls within the normal range (typically 1.010 to 1.030). An appropriate specific gravity indicates that the client's kidneys are responding well to the IV fluids, maintaining adequate urine output and concentration.

Choice B rationale:

Potassium level of 5.2 mEq/L is above the normal range of 3.5 to 5 mEq/L. However, this value does not specifically indicate whether the client is responding effectively to the IV fluids for dehydration.

Choice C rationale:

Hct (Hematocrit) of 6296 is not a valid measurement; it appears to be a typographical error or an incomplete value. Therefore, it cannot be used to assess the client's response to treatment.

Choice D rationale:

Sodium level of 165 mEq/L is elevated beyond the normal range of 136 to 145 mEq/L. However, this value does not provide information about the client's response to IV fluids for dehydration.

Correct Answer is B

Explanation

Choice A rationale:

Narcotics are not known to directly cause hypokalemia. Their main effects are related to pain relief and central nervous system depression.

Choice B rationale:

Thiazide diuretics can cause potassium loss in the urine, leading to hypokalemia. These diuretics work by inhibiting sodium reabsorption in the distal convoluted tubule, which can lead to potassium excretion as well.

Choice C rationale:

Corticosteroids can cause sodium and water retention but are not typically associated with significant potassium abnormalities.

Choice D rationale:

Muscle relaxers are not known to cause hypokalemia. They primarily act on the neuromuscular junction and do not directly impact potassium levels.

A. 1000 milliliters. B. 600 milliliters. C. 1200 milliliters. D. 750 milliliters.

Correct Answer is B

Explanation

The correct answer is B. 600 milliliters.

Choice A rationale:

A 24-hour urine output of 1000 milliliters is within the normal range for an adult, indicating adequate kidney function and hydration.

Choice B rationale:

A 24-hour urine output of 600 milliliters is below the normal range (typically 800-2000 milliliters), which may indicate oliguria (reduced urine output) and could be a sign of renal impairment or dehydration. This warrants notifying the healthcare provider.

Choice C rationale:

A 24-hour urine output of 1200 milliliters is also within the normal range, suggesting normal kidney function and hydration status.

Choice D rationale:

A 24-hour urine output of 750 milliliters is slightly below the normal range but may not be immediately concerning unless accompanied by other symptoms. However, it is still important to monitor and possibly notify the healthcare provider if it persists.
