ATI Pharmacology Proctored Exam 2024
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. What is the action of Metformin?
- A. Decreasing intestinal glucose absorption
- B. Increasing sensitivity to insulin
- C. Decreasing hepatic glucose production
- D. All of the above
Correct answer: D
Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.
3. A client has a new prescription for Spironolactone. Which of the following findings should the nurse monitor as an adverse effect?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia as an adverse effect. Hyperkalemia can result in muscle weakness and cardiac dysrhythmias, making it essential for the nurse to monitor potassium levels closely when a client is on Spironolactone. Choice B, Hypoglycemia, is incorrect because Spironolactone is not known to cause low blood sugar levels. Choice C, Hypocalcemia, and Choice D, Hyponatremia, are also incorrect as Spironolactone is not associated with decreased levels of calcium or sodium.
4. A client has a new prescription for Calcitonin-salmon for Osteoporosis. Which of the following tests should the nurse tell the client to expect before beginning this medication?
- A. Skin test for allergy to the medication
- B. ECG to rule out cardiac dysrhythmias
- C. Mantoux test to rule out exposure to tuberculosis
- D. Liver function tests to assess risk for medication toxicity
Correct answer: A
Rationale: Before starting Calcitonin-salmon, it is important to assess for any potential allergies as anaphylaxis can occur. A skin test is usually conducted to determine if the client is allergic to the medication. The nurse should also inquire about any previous allergies to fish, as Calcitonin-salmon is derived from salmon. Options B, C, and D are not necessary before initiating Calcitonin-salmon therapy. ECG is not directly related to this medication, Mantoux test is used to diagnose tuberculosis, and liver function tests are not specifically required before starting Calcitonin-salmon.
5. A healthcare professional is preparing to administer IV Vancomycin to a client who has a systemic infection. Which of the following actions should the healthcare professional take?
- A. Administer the medication rapidly over 15 minutes.
- B. Monitor the client for hypertension during infusion.
- C. Administer a test dose before the full dose.
- D. Monitor the client for Red Man Syndrome.
Correct answer: D
Rationale: The correct action for the healthcare professional is to monitor the client for Red Man Syndrome. Red Man Syndrome is a common adverse reaction to Vancomycin characterized by flushing, rash, and hypotension. It is important to monitor the client for these symptoms to intervene promptly if they occur.
