1. What is the pharmacological action of metformin?
- A. Blocks stimulation of beta1 and beta2.
- B. Blocks vasoconstriction and aldosterone.
- C. Acts at many levels in the CNS to produce an anxiolytic effect.
- D. Decreases hepatic glucose production.
Correct answer: D
Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
2. A drug ending in the suffix (tidine) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct answer: D
Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.
3. A client has a new prescription for Metformin. Which of the following adverse effects of Metformin should the nurse instruct the client to report to the provider?
- A. Somnolence
- B. Constipation
- C. Fluid retention
- D. Weight gain
Correct answer: A
Rationale: The correct answer is 'A: Somnolence.' Somnolence can indicate lactic acidosis, which is manifested by extreme drowsiness, hyperventilation, and muscle pain. It is a rare but very serious adverse effect caused by metformin and should be reported to the provider promptly to prevent further complications.
4. A client has a new prescription for Folic Acid. Which of the following client statements indicates an understanding of the teaching?
- A. I will take this medication with food.
- B. I need to monitor for skin rash while taking this medication.
- C. I need to increase my intake of green, leafy vegetables.
- D. I will stop taking this medication if I feel nauseous.
Correct answer: C
Rationale: The correct answer is C. Folic acid is naturally found in green, leafy vegetables such as spinach and broccoli. Increasing the intake of these vegetables can supplement the prescribed folic acid and help maintain adequate levels in the body. It is essential to understand that dietary sources of folic acid can complement the medication and support overall health. Choices A, B, and D are incorrect because taking folic acid with food, monitoring for skin rash, or stopping the medication if feeling nauseous do not directly relate to enhancing the therapeutic effects of folic acid through dietary intake.
5. A client has a new prescription for Captopril. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor your blood pressure weekly.
- C. Notify your provider if you develop a persistent cough.
- D. Avoid using salt substitutes to prevent hyperkalemia.
Correct answer: C
Rationale: Clients prescribed with Captopril, an ACE inhibitor, are at risk of developing a persistent cough as a common adverse effect. It is essential for the client to inform their healthcare provider promptly if this side effect occurs to evaluate the need for a medication change or adjustment.
