ATI Pharmacology Proctored Exam 2023
1. A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The healthcare provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?
- A. Bursitis
- B. Sinusitis
- C. Depression
- D. Glaucoma
Correct answer: D
Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Choosing option D, Glaucoma, as the correct answer is crucial for the client's safety and to prevent exacerbation of their eye condition. Options A, B, and C are not contraindications for Oxybutynin use and are unrelated to the pharmacological effects of this medication.
2. A nurse is assessing a client who is receiving IV vancomycin. The nurse notes a flushing of the neck and tachycardia. Which of the following actions should the nurse take?
- A. Document that the client experienced an anaphylactic reaction to the medication.
- B. Change the IV infusion site.
- C. Decrease the infusion rate on the IV.
- D. Apply cold compresses to the neck area.
Correct answer: C
Rationale: Flushing and tachycardia are signs of Red Man Syndrome, which can be mitigated by decreasing the infusion rate.
3. A healthcare professional is reviewing the laboratory results of a client taking Warfarin for atrial fibrillation. Which of the following findings should the professional report to the provider immediately?
- A. INR of 4.0
- B. Potassium level of 4.5 mEq/L
- C. Creatinine level of 1.0 mg/dL
- D. BUN of 18 mg/dL
Correct answer: A
Rationale: An INR of 4.0 indicates that the client's blood is clotting too slowly, increasing the risk of bleeding. This level is above the therapeutic range for a client on Warfarin therapy. Therefore, the healthcare professional should notify the provider immediately to prevent potential bleeding complications. The other laboratory values are within normal limits and do not pose an immediate risk to the client's health while on Warfarin therapy.
4. When teaching a client with schizophrenia strategies to cope with anticholinergic effects of Fluphenazine, which of the following should the nurse suggest to minimize anticholinergic effects?
- A. Take the medication in the morning to prevent insomnia.
- B. Chew sugarless gum to moisten the mouth.
- C. Use cooling measures to decrease fever.
- D. Take an antacid to relieve nausea.
Correct answer: B
Rationale: The correct answer is B: 'Chew sugarless gum to moisten the mouth.' Chewing sugarless gum can help alleviate dry mouth, which is a common anticholinergic effect of Fluphenazine. Dry mouth can be uncomfortable and affect the client's oral health. Options A, C, and D are incorrect because they do not directly address anticholinergic effects. Taking the medication in the morning to prevent insomnia (Option A) is unrelated to anticholinergic effects. Using cooling measures to decrease fever (Option C) is not a common anticholinergic effect of Fluphenazine. Taking an antacid to relieve nausea (Option D) does not specifically target anticholinergic effects.
5. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: A
Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.
