ATI Pharmacology Proctored Exam 2023
1. A healthcare provider is assessing a client who takes Lithium Carbonate for the treatment of Bipolar disorder. The provider should recognize which of the following findings as a possible indication of toxicity to this medication?
- A. Severe hypertension
- B. Coarse tremors
- C. Constipation
- D. Muscle spasm
Correct answer: B
Rationale: Coarse tremors are a common sign of Lithium toxicity. It is important for healthcare providers to monitor for this symptom as it indicates a potential overdose of the medication. Severe hypertension, constipation, and muscle spasms are not typically associated with Lithium toxicity. Severe hypertension is not a common sign of Lithium toxicity but rather a symptom of hypertensive crisis. Constipation is not a typical sign of Lithium toxicity but could be seen in other conditions. Muscle spasms are not specific to Lithium toxicity but can occur due to various reasons.
2. 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.
3. A client has a new prescription for Raltegravir. Which of the following statements should the nurse include in teaching the client?
- A. This medication prevents the virus from entering the cell.
- B. This medication prevents the virus from leaving the cell.
- C. This medication blocks the virus from attaching to the cell.
- D. This medication blocks the virus from replicating in the cell.
Correct answer: D
Rationale: The correct answer is D because Raltegravir works by blocking the integrase enzyme, preventing the virus from integrating its genetic material into the host cell's DNA. By inhibiting this process, viral replication within the host cell is halted. Choices A, B, and C are incorrect because Raltegravir's mechanism of action specifically targets viral replication within the cell, not virus entry, exit, or attachment to the cell.
4. Which of the following is the antidote for Heparin toxicity?
- A. Protamine
- B. Methylene blue
- C. N-acetylcysteine
- D. Glucagon
Correct answer: A
Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.
5. A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?
- A. A headache indicates a serious allergic reaction to nitroglycerin.
- B. The client will not have a headache if the nitroglycerin is taken with a high-fat meal.
- C. Nitroglycerin does not cause a headache.
- D. The most common side effect of nitroglycerin is a headache.
Correct answer: D
Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.
