1. A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
2. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
3. A client has been prescribed diltiazem (Cardizem) and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?
- A. “A beta blocker.”
- B. “A sodium channel blocker.”
- C. “An alpha blocker.”
- D. “A calcium channel blocker.”
Correct answer: D
Rationale: Diltiazem (Cardizem) belongs to the class of drugs known as calcium channel blockers. These medications work by blocking calcium from entering the muscle cells of the heart and blood vessels, leading to relaxation of the blood vessels and reduced workload on the heart. This helps in lowering blood pressure and improving blood flow. It is crucial for the nurse to provide accurate information to the client about the type of drug prescribed to ensure understanding and compliance with the treatment plan.
4. 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.
5. A client taking nitroglycerin (Nitrostat) for angina asks the nurse to explain possible side effects. What should NOT be included in client teaching?
- A. Reflex tachycardia
- B. Dizziness
- C. Hyponatremia
- D. Hypotension
Correct answer: C
Rationale: Hyponatremia is not a common side effect associated with nitroglycerin use. Nitroglycerin typically causes side effects such as reflex tachycardia, dizziness, and hypotension due to its vasodilatory effects. Therefore, it is important for the nurse to educate the client about these potential side effects to promote understanding and appropriate management.
