ATI Pharmacology Proctored Exam 2024
1. A staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)
- A. Increased renal secretion
- B. Increased medication-metabolizing enzymes
- C. Liver failure
- D. Peripheral vascular disease
Correct answer: C
Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.
2. A client is starting to take amitriptyline. The healthcare provider should instruct the client to monitor for which of the following adverse effects?
- A. Diarrhea
- B. Urinary retention
- C. Bradycardia
- D. Dry cough
Correct answer: B
Rationale: The correct answer is B: Urinary retention. Amitriptyline, a tricyclic antidepressant, can cause relaxation of the bladder sphincter muscles, leading to urinary retention. Monitoring for urinary retention is crucial as it is a common anticholinergic effect associated with this medication. Diarrhea (choice A) is not a common adverse effect of amitriptyline. Bradycardia (choice C) is more commonly associated with beta-blockers rather than tricyclic antidepressants like amitriptyline. Dry cough (choice D) is not a typical adverse effect of amitriptyline.
3. 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.
4. A healthcare provider is preparing to administer an IV bolus of Morphine to a client for pain management. Which of the following assessments is the healthcare provider's priority?
- A. Respiratory rate
- B. Pain level
- C. Blood pressure
- D. Level of consciousness
Correct answer: A
Rationale: The priority assessment for a healthcare provider preparing to administer an IV bolus of Morphine is the client's respiratory rate. Morphine can cause respiratory depression as a significant adverse effect, so monitoring the respiratory rate is crucial to detect any signs of respiratory compromise and intervene promptly. Assessing the respiratory rate takes precedence over other assessments because respiratory depression can lead to serious complications. While pain level, blood pressure, and level of consciousness are important assessments, they are not the priority when administering Morphine, as the risk of respiratory depression is a more immediate concern.
5. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to the same site each day.
- B. Remove the patch at night.
- C. Cover the patch with a heating pad.
- D. Apply the patch to a hairless area of skin.
Correct answer: D
Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This is important for proper absorption of the medication. Additionally, rotating the patch to different sites each day helps prevent skin irritation and ensures optimal therapeutic effect. Applying the patch to the same site each day can lead to skin irritation or tolerance development. Removing the patch at night is not necessary as the patch is typically worn continuously to provide a consistent level of medication. Covering the patch with a heating pad is contraindicated as it can increase drug absorption, potentially leading to adverse effects.
