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. Place the patient on a cardiac monitor and check the patency of the IV: Hypokalemia (K+ = 2.5 mEq/L) can cause life-threatening cardiac dysrhythmias, so cardiac monitoring is essential. Additionally, potassium is highly irritating to veins, so IV patency must be confirmed to prevent extravasation and tissue damage.

B. Administer potassium intravenously in an IV push bolus- NEVER give potassium IV push as it can cause fatal cardiac arrest. Potassium must always be diluted and infused slowly.

C. Discontinue other medications that may affect potassium levels- Adjusting medications may be necessary, but not an immediate priority over cardiac monitoring.

D. Avoid potassium-rich foods in the diet - Incorrect because the client needs potassium replacement, not restriction.

A. having no currently accepted medical use and high potential for abuse B. having a high potential for psychological or physical dependence C. having a moderate potential for psychological or physical dependence D. having a low potential for psychological or physical dependence

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.
