Question 1 of 5
A client is taking metformin for type 2 diabetes. Which of the following findings should indicate to the nurse that the medication is effective?
Correct Answer: C
Rationale: A decrease in hemoglobin A1C is a more specific indicator of metformin's effectiveness in controlling blood glucose levels over a longer period compared to fasting blood glucose levels. Hemoglobin A1C reflects average blood sugar levels over the past 2-3 months, providing a more comprehensive view of glycemic control.
Question 2 of 5
A client has a new prescription for hydrochlorothiazide to treat hypertension. Which of the following instructions should be included?
Correct Answer: B
Rationale: Hydrochlorothiazide, a diuretic, can cause hypokalemia by promoting potassium excretion. Increasing potassium-rich foods, such as bananas or oranges, can help counteract this effect and maintain electrolyte balance.
Question 3 of 5
While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
Correct Answer: A
Rationale: ACE inhibitors lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II. Angiotensin II is a potent vasoconstrictor, and by inhibiting its formation, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload on the heart.
Question 4 of 5
A client informs the nurse that she has difficulty swallowing tablets and struggles with liquid or chewable medications due to taste. What medication should the nurse request a prescription for when preparing to administer Penicillin V to treat the client's streptococcal infection?
Correct Answer: C
Rationale: Nafcillin is an appropriate alternative within the penicillin class for clients who have difficulty swallowing tablets or struggle with liquid or chewable medications. It is available for intramuscular (IM) or intravenous (IV) administration, offering options beyond oral formulations.
Question 5 of 5
A client has a prescription for Amoxicillin. Which of the following instructions should be included?
Correct Answer: D
Rationale: It is crucial for clients to complete the entire course of amoxicillin therapy to ensure the infection is fully treated and to prevent antibiotic resistance. Prematurely stopping the antibiotic can lead to incomplete eradication of the infection, potentially causing it to return and be more difficult to treat.
