1. What is the therapeutic use of Phenytoin?
- A. Replacement in hypothyroidism to restore normal hormonal balance
- B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
- C. Diminished seizure activity, termination of ventricular arrhythmias
- D. Prevention of thrombus formation, prevention of extension of existing thrombi
Correct answer: C
Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.
2. A client has a new prescription for Furosemide. Which of the following instructions should be included by the nurse?
- A. Take this medication at bedtime.
- B. Avoid eating foods high in potassium.
- C. Change positions slowly.
- D. Take this medication with meals.
Correct answer: C
Rationale: The correct instruction to include when a client is prescribed Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these potential adverse effects.
3. A client has a new prescription for Metronidazole. Which of the following instructions should be included?
- A. Avoid drinking alcohol while taking this medication.
- B. Take the medication on an empty stomach.
- C. Increase your intake of green, leafy vegetables.
- D. Discontinue the medication if you experience a metallic taste.
Correct answer: A
Rationale: The correct instruction for a client prescribed Metronidazole is to avoid drinking alcohol while taking this medication. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, resulting in severe nausea, vomiting, and other adverse effects. Therefore, it is crucial for clients to refrain from consuming alcohol during treatment to prevent these potential complications. Choice B is incorrect because Metronidazole can be taken with or without food. Choice C is irrelevant as there is no specific requirement to increase green, leafy vegetable intake with Metronidazole. Choice D is incorrect as a metallic taste is a known side effect of Metronidazole but does not necessarily indicate the need to discontinue the medication.
4. When administering Amitriptyline to a client experiencing cancer pain, for which of the following adverse effects should the nurse monitor?
- A. Decreased appetite
- B. Explosive diarrhea
- C. Decreased pulse rate
- D. Orthostatic hypotension
Correct answer: D
Rationale: Corrected Question: When administering Amitriptyline to a client experiencing cancer pain, for which of the following adverse effects should the nurse monitor? Amitriptyline is known to cause orthostatic hypotension, a sudden drop in blood pressure when moving from lying down or sitting to a standing position. Monitoring for orthostatic hypotension is crucial to prevent falls and related injuries. Educating the client about moving slowly and changing positions gradually can help mitigate this adverse effect. Choices A, B, and C are incorrect because decreased appetite, explosive diarrhea, and decreased pulse rate are not commonly associated with Amitriptyline use. Therefore, the correct answer is D.
5. A client has a new prescription for rituximab. Which of the following findings should the nurse instruct the client to report?
- A. Dizziness
- B. Fever
- C. Urinary frequency
- D. Dry mouth
Correct answer: B
Rationale: The nurse should instruct the client to report fever. Fever can be an indication of an infection, a potential complication of rituximab therapy. Monitoring and reporting fever promptly can help in early intervention to prevent further complications. Dizziness, urinary frequency, and dry mouth are not typically associated with rituximab therapy and are less likely to be directly related to the medication. Therefore, they are not the priority findings to report in this scenario.
