1. 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.
2. When administering Lithium to a patient, what is a life-threatening side effect?
- A. Erythema
- B. Pancreatitis
- C. Seizures
- D. Headache
Correct answer: C
Rationale: When a patient is being treated with Lithium, a life-threatening side effect to watch out for is seizures. Lithium can lower the seizure threshold, increasing the risk of seizures. Seizures are serious and necessitate prompt medical intervention to ensure the patient's safety and well-being. Erythema, which is redness of the skin, is not a common life-threatening side effect of Lithium. Pancreatitis can be a side effect of Lithium, but it is not typically life-threatening. Headache is a common side effect of Lithium, but it is not considered life-threatening.
3. A healthcare professional is preparing to administer Filgrastim for the first time to a client who has just undergone a bone marrow transplant. Which of the following interventions is appropriate?
- A. Administer intravenously to prevent injury.
- B. Ensure that the medication is kept refrigerated until just prior to administration.
- C. Do not shake the vial; gently invert it to mix before withdrawing the dose.
- D. Discard the vial after removing one dose of the medication.
Correct answer: D
Rationale: When administering Filgrastim, only one dose should be withdrawn from the vial, and the vial should then be discarded to prevent any contamination or errors in dosing. It is crucial not to shake the vial but gently invert it to mix the medication before withdrawing the appropriate dose. Refrigeration is not required for Filgrastim; it should be stored at room temperature until just before administration. Choice A is incorrect because Filgrastim is typically administered subcutaneously, not intravenously. Choice B is incorrect as the medication should be stored at room temperature, not refrigerated, until administration. Choice C is incorrect as shaking the vial is not recommended for Filgrastim.
4. A client in an acute care facility is receiving IV Nitroprusside for hypertensive crisis. The nurse should monitor the client for which of the following adverse reactions to this medication?
- A. Intestinal ileus
- B. Neutropenia
- C. Delirium
- D. Hyperthermia
Correct answer: C
Rationale: The correct answer is C: Delirium. When IV Nitroprusside is infused at high dosages, it can lead to thiocyanate toxicity, causing mental status changes such as delirium. It is crucial to monitor the thiocyanate levels to ensure they remain below 10 mg/dL during therapy to prevent adverse effects. Choices A, B, and D are incorrect because IV Nitroprusside is not commonly associated with intestinal ileus, neutropenia, or hyperthermia. Monitoring for delirium is crucial due to the risk of thiocyanate toxicity.
5. The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?
- A. Atenolol (Tenormin)
- B. Nitroglycerin (Nitrostat)
- C. Sildenafil (Viagra)
- D. Ranolazine (Ranexa)
Correct answer: D
Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.
