1. A client has been prescribed a calcium channel blocker for angina. The nurse knows this medication should NOT be used with caution in combination with which drug classes?
- A. NSAIDs
- B. Cardiac glycosides
- C. Beta blockers
- D. None of the above
Correct answer: C
Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.
2. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Increase your intake of potassium-rich foods.
- C. Expect decreased urination within the first few days.
- D. Avoid foods high in potassium.
Correct answer: B
Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.
3. A client with asthma has new prescriptions for cromolyn and albuterol by nebulizer. Which statement by the client indicates an understanding of the teaching?
- A. If my breathing begins to feel tight, I will use the cromolyn immediately.
- B. I will be sure to take the albuterol before taking the cromolyn.
- C. I will use both medications immediately after exercising.
- D. I will administer the medications 10 minutes apart.
Correct answer: B
Rationale: The correct answer is B. Taking albuterol before cromolyn ensures that the airways are open, allowing the cromolyn to reach the lungs effectively. Choice A is incorrect because cromolyn is a preventive medication and should be used regularly, not just when symptoms worsen. Choice C is incorrect because medications should be used as prescribed, not based on a specific event like exercising. Choice D is incorrect because there is no need to wait 10 minutes between administering these two medications when using a nebulizer.
4. A client has a prescription for long-term use of oral prednisone for the treatment of chronic asthma. The nurse should instruct the client to monitor for which of the following adverse effects of this medication?
- A. Weight gain
- B. Nervousness
- C. Bradycardia
- D. Constipation
Correct answer: A
Rationale: The correct answer is weight gain. Oral prednisone can lead to weight gain and fluid retention due to its sodium and water retention effects. Monitoring weight changes is crucial to identify and manage this adverse effect. Choices B, C, and D are incorrect because oral prednisone is not typically associated with nervousness, bradycardia, or constipation as common adverse effects. Therefore, the nurse should primarily focus on monitoring weight gain in clients prescribed long-term oral prednisone therapy.
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.
