ATI Pharmacology Proctored Exam 2023 Quizlet
1. When taking Digoxin, low levels of what can cause toxicity?
- A. Potassium
- B. Calcium
- C. Sodium
- D. Magnesium
Correct answer: A
Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.
2. A client has a new prescription for rituximab. Which of the following findings should the nurse instruct the client to report?
- A. Dizziness
- B. Fever
- C. Urinary frequency
- D. Dry mouth
Correct answer: B
Rationale: The nurse should instruct the client to report fever. Fever can be an indication of an infection, a potential complication of rituximab therapy. Monitoring and reporting fever promptly can help in early intervention to prevent further complications. Dizziness, urinary frequency, and dry mouth are not typically associated with rituximab therapy and are less likely to be directly related to the medication. Therefore, they are not the priority findings to report in this scenario.
3. A client has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to a non-hairy area.
- B. Change the patch every 72 hours.
- C. Avoid exposure to heat sources.
- D. Do not cut the patch to adjust the dosage.
Correct answer: C
Rationale: The correct instruction the nurse should include for a client using a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, potentially causing an overdose. Instructing the client to avoid heat sources is crucial to ensure their safety and the effectiveness of the medication. Choices A, B, and D are incorrect because applying the patch to a non-hairy area, changing it every 72 hours, and not cutting the patch are general guidelines for using transdermal patches but do not specifically address the unique risks associated with Fentanyl patches.
4. A client has a new prescription for allopurinol. Which of the following instructions should the nurse include?
- A. Drink 2 liters of water daily.
- B. Avoid taking the medication on an empty stomach.
- C. Limit vitamin C intake while taking this medication.
- D. Take an iron supplement while on this medication.
Correct answer: A
Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This recommendation aims to reduce the risk of kidney stones, a potential side effect associated with allopurinol use. Adequate hydration helps prevent the formation of uric acid crystals in the kidneys, which can lead to kidney stones. Therefore, encouraging increased water intake is essential in the management of clients taking allopurinol.
5. A client with heart failure is receiving instructions about laxative use. The client should be advised to avoid which of the following laxatives?
- A. Sodium phosphate
- B. Psyllium
- C. Bisacodyl
- D. Polyethylene glycol
Correct answer: A
Rationale: Clients with heart failure often have sodium restrictions. Sodium phosphate can lead to fluid retention due to sodium absorption, which is harmful for individuals with heart failure. Therefore, it should be avoided in this population to prevent exacerbating fluid overload. Psyllium, Bisacodyl, and Polyethylene glycol are safer options for individuals with heart failure as they do not pose the risk of exacerbating fluid overload through sodium retention.
