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."
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. 1630 and 1930: Peak and trough levels are used to monitor drug effectiveness and prevent toxicity. Trough levels (lowest drug concentration) are drawn right before the next dose-1745 would be slightly too late. Peak levels (highest drug concentration) are drawn 30-60 minutes after administration (for IV drugs). Since the next dose is at 1800, the trough should be drawn just before the dose (1630) and the peak should be drawn 30-60 minutes after the dose (1930).
B. 1100 and 1700- Incorrect timing, not close to dose administration.
C. 1400 and 2200- Too far from the scheduled 1800 dose.
D. 1745 and 1830- Trough is too close to administration, peak is too early.
Correct Answer is D
Explanation
A. Having no currently accepted medical use and high potential for abuse: Describes Schedule I drugs (e.g., heroin, LSD, ecstasy).
B. Having a high potential for psychological or physical dependence: Describes Schedule II drugs (e.g., morphine, oxycodone).
C. Having a moderate potential for psychological or physical dependence: Describes Schedule III drugs (e.g., codeine-containing medications).
D. Having a low potential for psychological or physical dependence: Schedule IV drugs (e.g., benzodiazepines like diazepam and tramadol) have a low potential for abuse and dependence compared to Schedule I-III substances.
