ATI Pharmacology Proctored Exam 2019
1. A client is prescribed Spironolactone. Which of the following laboratory findings should the nurse monitor and report to the provider?
- A. Sodium level of 138 mEq/L
- B. Potassium level of 5.2 mEq/L
- C. Chloride level of 100 mEq/L
- D. Calcium level of 9.5 mg/dL
Correct answer: B
Rationale: Spironolactone is a potassium-sparing diuretic, causing potassium retention, potentially leading to elevated potassium levels. A potassium level of 5.2 mEq/L is above the normal range (3.5-5.0 mEq/L), indicating hyperkalemia, a serious condition. Elevated potassium levels can lead to life-threatening cardiac arrhythmias. Monitoring and reporting high potassium levels promptly to the healthcare provider are crucial to prevent potential complications. Sodium, chloride, and calcium levels are not directly influenced by Spironolactone, making choices A, C, and D incorrect.
2. When a nurse assesses a client's IV catheter insertion site and notes a hematoma, which of the following actions should the nurse take? (Select all that apply.)
- A. Stop the infusion.
- B. Apply alcohol to the insertion site.
- C. Apply warm compresses to the insertion site.
- D. Elevate the client's arm.
Correct answer: C
Rationale: When a nurse detects a hematoma at the IV catheter insertion site, applying warm compresses is beneficial as it can promote healing by enhancing circulation and reducing swelling. Elevating the client's arm helps in reducing edema, which can relieve pressure, pain, and further bleeding in the hematoma area. Stopping the infusion may be necessary in certain situations, but it is not a standard action for all hematoma cases. Applying alcohol to the insertion site is discouraged as it can cause irritation and may not aid in resolving the hematoma.
3. A client is taking naproxen following an exacerbation of rheumatoid arthritis. Which of the following statements by the client requires further discussion?
- A. I signed up for a swimming class.
- B. I've been taking an antacid to help with indigestion.
- C. I've lost 2 pounds since my appointment 2 weeks ago.
- D. The naproxen is easier to take when I crush it and put it in applesauce.
Correct answer: B
Rationale: The client stating that they have been taking an antacid to help with indigestion while on naproxen requires further discussion. This statement suggests potential gastrointestinal distress or interactions between the medications. Antacids can affect the absorption of naproxen or lead to other complications. Therefore, the nurse should address this statement with the client to ensure safe and effective medication management. Choices A, C, and D do not raise immediate concerns related to the client's medication regimen and can be considered positive health behaviors or side effects of treatment that do not require immediate intervention.
4. What is the expected pharmacological action of propranolol?
- A. Block stimulation of beta1 receptors
- B. Alter water and electrolyte transport in the large intestine
- C. Block stimulation of beta2 receptors
- D. Both A and C are correct
Correct answer: D
Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.
5. 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.
