1. What should a patient avoid while taking Angiotensin-converting enzymes?
- A. Salt substitutes
- B. Foods high in potassium
- C. Foods high in sodium
- D. All of the above
Correct answer: A
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
2. 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.
3. What is the action of Nitroglycerin?
- A. Dilates the Bronchi
- B. Reduces Blood Glucose
- C. Reduces Nausea
- D. Dilates Coronary Arteries
Correct answer: D
Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.
4. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?
- A. Perform immediate gastric lavage.
- B. Prepare the client for hemodialysis.
- C. Administer an additional oral dose of lithium.
- D. Request a stat repeat of the laboratory test.
Correct answer: A
Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.
5. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent drowsiness.
- B. Take this medication with a glass of milk.
- C. Take this medication with a glass of juice.
- D. Take this medication at the same time every day.
Correct answer: A
Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
