Correct Answer is A

Explanation

A. A client who has a prescription for heparin and an aPTT of 90 seconds (30-40 seconds).: This is significantly elevated and indicates a risk for bleeding, as the therapeutic range for heparin is typically 1.5–2.5 times the normal value.
B. A client who has a prescription for warfarin and an INR of 2.0 (0.8 to 1.1): This is within the therapeutic range for most conditions treated with warfarin (e.g., 2.0–3.0).
C. A client who has a prescription for heparin and an aPTT of 65 seconds (30-40 seconds): This is slightly elevated but still within the therapeutic range for heparin (typically 60–80 seconds).
D. A client who has a prescription for warfarin and an INR of 3.0 (0.8 to 1.1): This is within the therapeutic range for most warfarin indications.

A. "Contact the provider if you experience unexplained muscle pain." B. "Take the medication at bedtime." C. "Discard excess medication after 60 days." D. "Inject the medication into the subcutaneous tissue of your abdomen."

Correct Answer is D

Explanation

A. "Contact the provider if you experience unexplained muscle pain.": Muscle pain is not a typical adverse effect of exenatide; this advice would apply to statins or drugs associated with rhabdomyolysis.
B. "Take the medication at bedtime.": Exenatide is usually taken twice daily, 1 hour before morning and evening meals, not at bedtime.
C. "Discard excess medication after 60 days.": Exenatide pens should typically be discarded 30 days after opening, not 60 days.
D. "Inject the medication into the subcutaneous tissue of your abdomen.": Correct. Exenatide is administered subcutaneously, typically in the abdomen, thigh, or upper arm.
