A nurse is reviewing the laboratory results for four clients. Which of the following results is the priority for the nurse to report to the provider?
WBC 11,000/mm² in a client who is starting treatment for a methicillin-resistant staphylococcus aureus (MRSA) infection.
Serum pH 7.25 in a client who has type 1 diabetes mellitus.
Hematocrit 26% in a client who has sickle cell disease.
Urine specific gravity 1.032 in a client who is diagnosed with dehydration.
The Correct Answer is B
Choice A rationale:
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
Choice B rationale:
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
Choice C rationale:
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
Choice D rationale:
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.

Correct Answer is B
Explanation
Choice A rationale:
An INR (International Normalized Ratio) of 0.8 is within the normal range for someone not on anticoagulation therapy. The aPTT (activated partial thromboplastin time) of 85 seconds is prolonged, but it is not a reason to withhold heparin in itself. Therefore, the nurse should not withhold the medication for these values.
Choice B rationale:
An INR of 2 indicates the client's blood is taking twice as long to clot compared to the average, which can increase the risk of bleeding. The aPTT of 60 seconds is within the normal range. However, the elevated INR suggests the client might be overly anticoagulated, so the nurse should withhold the medication and notify the provider.
Correct Answer is D
Explanation
Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.
