1. When a client with hepatic encephalopathy is receiving lactulose, which parameter is essential to monitor for a response to the drug?
- A. Serum hepatic enzymes
- B. Fingerstick glucose
- C. Stool color and character
- D. Serum electrolytes and ammonia
Correct answer: D
Rationale: In hepatic encephalopathy, the goal of lactulose therapy is to reduce blood ammonia levels by promoting its excretion in the stool. Therefore, monitoring serum electrolytes and ammonia levels is crucial to assess the effectiveness of lactulose in lowering ammonia levels and improving the client's condition. Options A, B, and C are incorrect because serum hepatic enzymes, fingerstick glucose, and stool color/character are not directly related to monitoring the response to lactulose therapy in hepatic encephalopathy.
2. A client undergoing hemodialysis for chronic kidney disease is taking the medication erythropoietin. The nurse should reinforce instructions to explain for which reason this medication is prescribed?
- A. This drug prevents infections associated with dialysis.
- B. This drug prevents deep vein thrombosis in older clients.
- C. This drug helps stimulate the production of red blood cells.
- D. This drug helps balance the level of phosphorus in the body.
Correct answer: C
Rationale: Erythropoietin is prescribed to stimulate the production of red blood cells. Clients undergoing hemodialysis often develop anemia due to end-stage renal disease. Erythropoietin helps correct this anemia by stimulating red blood cell production. It is not used to prevent infections associated with dialysis, prevent deep vein thrombosis, or balance phosphorus levels in the body.
3. The healthcare provider notes that a client has a new prescription for 20 mEq of potassium. The IV site is inflamed but not tender, and has a blood flashback. What action should the healthcare provider take?
- A. Obtain a liter of normal saline with 20 mEq of KCl
- B. Contact the healthcare provider to clarify the prescription
- C. Withhold the prescription medication until a new IV is started
- D. Fax the prescription to the pharmacy for immediate dispensing
Correct answer: B
Rationale: The healthcare provider should contact the prescriber to clarify the prescription because an inflamed IV site may indicate potential issues with administering the medication. It is important to ensure that the prescription is appropriate and safe for the client before proceeding with administration. Option A is incorrect because administering potassium through an inflamed IV site can lead to further complications. Option C is not the best course of action as clarifying the prescription first is essential. Option D is also incorrect as the focus should be on ensuring the safety of the client before dispensing the medication.
4. A client with diabetes mellitus type 2 is prescribed metformin. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of lactic acidosis to the healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client prescribed metformin is to take the medication with meals. Taking metformin with meals helps to minimize gastrointestinal side effects, which are common with this medication. Choice B, avoiding alcohol, is a good practice due to the increased risk of lactic acidosis when alcohol is consumed with metformin; however, it is not the priority teaching point in this scenario. Taking metformin on an empty stomach (Choice C) is incorrect because it can increase the risk of gastrointestinal side effects. Reporting signs of lactic acidosis (Choice D) is important, but it is more related to monitoring for adverse effects rather than a primary teaching point for administration.
5. A client who was diagnosed with oral thrush calls the clinic saying the medication bottle broke and all of the medication was spilled. The client is requesting a refill order. The nurse should contact the health care provider about a refill for which medication?
- A. Ampicillin
- B. Ciprofloxacin
- C. Neomycin sulfate
- D. Nystatin
Correct answer: D
Rationale: Nystatin is the appropriate medication for treating oral thrush as it is an antifungal drug specifically used for fungal infections. It targets the fungus responsible for thrush, Candida, effectively. Therefore, the nurse should contact the healthcare provider to request a refill of Nystatin for the client.
