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 D

Explanation

A. Nursing drug guide: A nursing drug guide is a textbook or app containing information on multiple drugs, not a single-drug insert.

B. Package insert; A package insert is provided by the manufacturer and contains information such as indications, side effects, contraindications, and dosing guidelines.

C. Physician’s drug reference: The Physician’s Desk Reference (PDR) is a compilation of drug package inserts.

D. Drug label: A drug label is found on the bottle or box and provides basic dosing and safety instructions, not detailed pharmacological data.

A. Trailing B. Double C. Leading D. Decimal point

Correct Answer is C

Explanation

A. Trailing: Incorrect because trailing zeros (e.g., 5.0 mg) should be avoided, as 5.0 mg could be misread as 50 mg.

B. Double: Not relevant to numeric safety measures.

C. Leading: A leading zero (e.g., 0.5 mg instead of .5 mg) helps prevent medication errors. Without a leading zero, .5 mg could be misread as 5 mg, leading to a dangerous overdose.

Correct Answer: C

D. Decimal point: This refers to the proper use of decimal points in dose documentation. While using decimal points is critical, this alone doesn’t address all potential errors related to formatting (e.g., leading or trailing zeros).
