1. 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.
2. Which drug classes are NOT typically used to treat angina?
- A. Calcium channel blockers
- B. Organic nitrates
- C. Alpha blockers
- D. Beta blockers
Correct answer: C
Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
3. A client is taking Glipizide to treat Diabetes Mellitus. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of this medication?
- A. Cholesterol level.
- B. Hematocrit.
- C. Blood glucose level.
- D. Calcium level.
Correct answer: C
Rationale: The correct answer is C: Blood glucose level. Monitoring the client's blood glucose level is crucial when taking Glipizide, a medication used to lower blood glucose levels in individuals with Diabetes Mellitus. By monitoring the blood glucose level, the nurse can evaluate the effectiveness of the medication in managing the client's condition. Choices A, B, and D are incorrect as they are not directly related to assessing the effectiveness of Glipizide in treating Diabetes Mellitus. Cholesterol level, hematocrit, and calcium level may be important for other aspects of the client's health but are not the primary indicators of Glipizide's effectiveness.
4. When a client reports urticaria and dyspnea after receiving amoxicillin/clavulanic acid, which medication should be administered first?
- A. Administer epinephrine
- B. Administer albuterol
- C. Administer diphenhydramine
- D. Administer prednisone
Correct answer: A
Rationale: In the scenario described, the client is experiencing symptoms of a severe allergic reaction. The priority intervention is to administer epinephrine. Epinephrine acts quickly to reverse the effects of the allergic reaction and can be life-saving in cases of anaphylaxis. Albuterol is used for bronchodilation and may help with respiratory symptoms but is not the first-line treatment for anaphylaxis. Diphenhydramine and prednisone are used for allergic reactions but are not as rapid-acting as epinephrine and should be considered after administering epinephrine in this situation.
5. A client has a new prescription for Digoxin. Which of the following instructions should the nurse provide?
- A. Monitor your heart rate before taking the medication.
- B. Increase your intake of high-potassium foods.
- C. Take the medication with a full glass of milk.
- D. Expect your stools to be black and tarry.
Correct answer: A
Rationale: Clients prescribed Digoxin should monitor their heart rate before each dose. This is essential to identify any potential bradycardia, defined as a heart rate below 60 bpm, which can be a side effect of Digoxin. Any significant changes in heart rate should be reported promptly to the healthcare provider for further evaluation and management. Choice B is incorrect because increasing intake of high-potassium foods can lead to hyperkalemia, a condition that can be exacerbated by Digoxin. Choice C is incorrect as taking Digoxin with a full glass of milk is not necessary. Choice D is incorrect as black, tarry stools are not an expected side effect of Digoxin.
