ATI Pharmacology Quizlet
1. When educating a client who has a prescription for Levothyroxine, which instruction should the nurse include?
- A. Take this medication on an empty stomach.
- B. Take this medication with food.
- C. Take this medication at bedtime.
- D. Take this medication with antacids.
Correct answer: A
Rationale: The correct instruction for taking Levothyroxine is on an empty stomach. This helps to enhance the absorption and effectiveness of the medication. Consuming it with food or antacids can impede its absorption, leading to decreased efficacy.
2. A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?
- A. Nausea
- B. Epistaxis
- C. Diarrhea
- D. Dyspepsia
Correct answer: B
Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.
3. A client has a new prescription for Lithium Carbonate. When teaching the client about ways to prevent Lithium toxicity, what advice should the nurse provide?
- A. Avoid using acetaminophen for headaches.
- B. Restrict intake of foods high in sodium.
- C. Decrease fluid intake to less than 1,500 mL daily.
- D. Limit aerobic activity in hot weather.
Correct answer: D
Rationale: The nurse should advise the client to limit aerobic activity in hot weather to prevent sodium/water depletion, which can increase the risk for Lithium toxicity. Excessive sweating and fluid loss can lead to dehydration and changes in lithium levels, potentially resulting in toxicity. Choices A, B, and C are incorrect. Avoiding acetaminophen for headaches is not directly related to Lithium toxicity. Restricting sodium intake and decreasing fluid intake can lead to increased lithium levels and toxicity, so these are not recommended actions.
4. A client has a new prescription for Valsartan, and a nurse is providing discharge teaching. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid potassium-rich foods.
- C. Expect to feel drowsy.
- D. Monitor your blood pressure daily.
Correct answer: D
Rationale: Monitoring blood pressure daily is crucial for clients taking Valsartan, an angiotensin II receptor blocker, to ensure effective management of hypertension. Valsartan helps lower blood pressure by relaxing blood vessels, and regular monitoring helps track the medication's effectiveness and any potential side effects. Choices A, B, and C are incorrect because Valsartan does not need to be taken with food, avoiding potassium-rich foods is not specifically required for this medication, and feeling drowsy is not a common side effect of Valsartan.
5. A client asks the nurse how Rituximab works, which the client is receiving to treat Non-Hodgkin's Leukemia. Which of the following should the nurse include?
- A. Blocks hormone receptors
- B. Increases immune response
- C. Binds with specific antigens on tumor cells
- D. Stops DNA replication during cell division
Correct answer: C
Rationale: Rituximab is a monoclonal antibody that binds with specific antigens on B-lymphocytes, leading to the destruction of cancer cells. In the context of Non-Hodgkin's Leukemia, Rituximab targets and destroys cancerous B-lymphocytes, which helps in treating the disease. Choices A, B, and D are incorrect. Rituximab does not block hormone receptors, increase immune response, or stop DNA replication during cell division. The primary mode of action of Rituximab is its binding with specific antigens on tumor cells, specifically B-lymphocytes, to elicit an immune response against cancerous cells.
