A nurse is caring for a patient who is receiving IV fluids to correct dehydration. Which of the following laboratory values should indicate to the nurse that the patient is effectively responding to treatment?
Urine specific gravity of 1.020
Serum sodium of 165 mEq/L
Hematocrit of 48%
Blood urea nitrogen (BUN) of 12 mg/dL
The Correct Answer is A
Choice A reason: Urine specific gravity measures the kidney's ability to concentrate urine. A normal range is typically 1.005–1.030. A value of 1.020 indicates adequate hydration and suggests that the patient is responding well to IV fluid therapy.
Choice B reason: Serum sodium levels reflect electrolyte balance. The normal range is 135–145 mEq/L. A level of 165 mEq/L is significantly elevated, indicating hypernatremia, which could be a sign of inadequate hydration and not a positive response to treatment.
Choice C reason: Hematocrit represents the proportion of blood volume occupied by red blood cells. Normal ranges are 38.3–48.6% for men and 35.5–44.9% for women. A hematocrit of 48% is at the upper limit of normal and does not specifically indicate the effectiveness of dehydration treatment.
Choice D reason: Blood urea nitrogen (BUN) levels can indicate renal function and hydration status. The normal range is 7–20 mg/dL. A BUN of 12 mg/dL is within the normal range and does not specifically reflect the patient's response to IV fluids for dehydration.

Correct Answer is C
Explanation
Choice A: Sleepy, but arousing when the name is called
Feeling sleepy after receiving morphine is a common side effect. However, the fact that the client can be aroused when their name is called suggests that this is not necessarily an adverse effect.
The nurse should continue monitoring the client but may not consider this as a significant adverse reaction.
Choice B: Pain level of 6 on a scale from 0 to 10
Pain relief is one of the intended effects of morphine. Therefore, experiencing pain reduction is not an adverse effect.
The nurse would likely view this as a positive response to the medication.
Choice C: Respiratory rate of 8/min
A respiratory rate of 8 breaths per minute is significantly low and indicates respiratory depression, which is a serious adverse effect of morphine.
The nurse should be concerned about this finding and take appropriate action.
Choice D: SaO2 94%
An oxygen saturation (SaO2) level of 94% is within the normal range (usually 95% or higher). It is unlikely to be directly related to morphine administration.
While this value is not concerning, the nurse should continue monitoring the client's oxygen saturation.
Correct Answer is B
Explanation
Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.
Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.
Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.
Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.
