A nurse is reviewing the laboratory results of a group of clients. Which of the following laboratory findings should the nurse report to the provider?
Glucose of 6.7 mg/dl
WBC of 7000/mm3
Platelet count of 160,000/mm3
Hemoglobin of 6.2 g/dl
The Correct Answer is D
A. Glucose of 6.7 mg/dL: Critically low; however, this is an unrealistic value because normal fasting glucose is 70-100 mg/dL. This might be a typo—if it were 6.7 mmol/L, it would be within the normal range.
B. WBC of 7000/mm³: Normal range (4,000-11,000/mm³), so no immediate concern.
C. Platelet count of 160,000/mm³: Normal range (150,000-400,000/mm³), so no immediate concern.
D. Hemoglobin of 6.2 g/dL: Normal hemoglobin levels are 13.5-17.5 g/dL (males) and 12-15.5 g/dL (females). A hemoglobin of 6.2 g/dL is critically low, indicating severe anemia, blood loss, or bone marrow suppression, which may require blood transfusion or further investigation.

Correct Answer is B
Explanation
A. A 1 mL TB syringe: Tuberculin syringes lack insulin unit markings, increasing the risk of dosing errors.
B. U-50 or U-100 insulin syringe: Insulin syringes are specifically calibrated in units, ensuring accurate insulin administration.
C. A 3 mL luer lock syringe: This type is not designed for insulin; it lacks unit measurements and may lead to errors.
D. Depends upon the type of insulin: All insulins should be administered using insulin syringes (U-50 or U-100), not different syringe types.
Correct Answer is A
Explanation
A. Distribution: Distribution refers to the movement of the drug from the bloodstream to tissues and organs. Poor circulation can impair drug distribution, leading to reduced effectiveness or toxic accumulation.
B. Excretion: Excretion is the elimination of drugs, primarily through the kidneys. While circulation plays a role, excretion is more directly affected by renal function.
C. Metabolism: Metabolism occurs primarily in the liver and is not the primary concern in a client with poor circulation.
D. Absorption: Absorption refers to how the drug enters the bloodstream, which is more dependent on the GI tract (oral meds) or injection site (IV, IM meds) rather than circulation.
