Extract:
Question 1 of 5
A nurse is reinforcing discharge teaching with a client who has a new diagnosis of type 2 diabetes mellitus and a prescription for exenatide. Which of the following instructions should the nurse include in the teaching?
Correct Answer: C
Rationale: Exenatide is typically administered before meals, not necessarily at bedtime. Discarding medication after a specified time is a general guideline, but it is not specific to exenatide. Exenatide is typically injected into the subcutaneous tissue of the abdomen to enhance absorption. While monitoring for adverse effects is important, muscle pain is not a commonly reported side effect of exenatide.
Question 2 of 5
A nurse is preparing to administer an antibiotic via intermittent IV bolus for a client who has a continuous IV infusion. Which of the following steps should the nurse take first?
Correct Answer: B
Rationale: Third, the nurse should connect the tubing of the medication bag to the primary tubing using a Y-connector or a piggyback port. First, the nurse should check the IV site for signs of infiltration, which means that the fluid is leaking into the surrounding tissue instead of the vein. Second, the nurse should hang the antibiotic medication bag above the level of the primary infusion. Fourth, the nurse should wipe the connection port of the primary IV tubing with an antiseptic swab to prevent contamination and infection.
Question 3 of 5
A nurse is obtaining a medication history from a client who has systemic lupus erythematosus (SLE) and reports taking several herbal supplements daily. The nurse should identify that SLE is a contraindication for taking which of the following herbal supplements?
Correct Answer: A
Rationale: Echinacea may stimulate the immune system, and in individuals with autoimmune disorders like SLE, this immune stimulation can exacerbate the condition. Flaxseed is generally considered safe for individuals with SLE. Ginger is generally considered safe for individuals with SLE. Glucosamine is generally considered safe for individuals with SLE.
Question 4 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The nurse should inject air into the NPH insulin vial first, then into the regular insulin vial, then withdraw the regular insulin first, followed by the NPH insulin. The nurse should inject air into each vial before withdrawing the insulin to prevent contamination and maintain the correct dosage. Insulin should be drawn up with an insulin syringe, not a tuberculin syringe. Shaking insulin vials is not recommended as it can cause denaturation of the insulin molecules.
Question 5 of 5
A nurse is reinforcing teaching with the family of a client who has a new prescription for donepezil. Which of the following therapeutic effects should the nurse inform the family to expect?

Rationale: Donepezil is used to treat Alzheimer's disease and is expected to improve cognitive function. Donepezil is not indicated for pulmonary function improvement. Donepezil is not primarily used for seizure control. Donepezil does not typically affect urinary output.
