In what syringe should a 6 25 ml of a drug solution be measured?
An insulin syringe
A 1 ml TB syringe
A 3 ml syringe
A 5 ml slip tip syringe
The Correct Answer is D
A. A 5 mL slip-tip syringe: A 5 mL syringe is the best option for measuring 6.25 mL, although it may require drawing up the medication in two separate amounts (e.g., 5 mL + 1.25 mL). A larger syringe (e.g., 10 mL) would be less precise.
B. An insulin syringe – Insulin syringes measure units of insulin, not milliliters, and are not appropriate for non-insulin medications.
C. A 1 mL TB syringe – This is used for very small doses (up to 1 mL) and is not practical for 6.25 mL.
D. A 3 mL syringe – This is too small for 6.25 mL.

Correct Answer is D
Explanation
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 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.
