A nurse is reinforcing teaching with a client scheduled for activated partial thromboplastin time (aPTT) testing. Which of the following statements made by the client indicates understanding of the teaching?

"This test shows if I am dehydrated."

"This test measures deficiencies in clotting factors."

"If my level is too low, I need to consume more sodium."

"The aPTT is used to measure my sugar levels."

Answer and Explanation

The Correct Answer is B

A. "This test shows if I am dehydrated." aPTT is not used to assess hydration status; it measures blood clotting ability.

B. "This test measures deficiencies in clotting factors." aPTT assesses the intrinsic clotting pathway and helps evaluate clotting factor deficiencies, especially in conditions like hemophilia or when a client is on heparin therapy.

C. "If my level is too low, I need to consume more sodium." Sodium intake does not directly impact aPTT values.

D. "The aPTT is used to measure my sugar levels." Glucose levels are measured by a blood sugar test, not an aPTT test.

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.

A. An insulin syringe B. A 1 ml TB syringe C. A 3 ml syringe D. A 5 ml slip tip syringe

Correct Answer is D

Explanation

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.
