1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?
- A. blood urea nitrogen
- B. serum calcium
- C. serum ammonia
- D. serum creatinine
Correct answer: C
Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.
2. A client whose right leg is in skeletal traction complains of pain in the leg. Which action should the nurse take first?
- A. Asking the client to wiggle their toes
- B. Medicating the client with the prescribed analgesic
- C. Realigning the client
- D. Removing some of the traction weights
Correct answer: C
Rationale: When a client in skeletal traction complains of pain, the priority action for the nurse is to realign the client. Severe pain may indicate the need for realignment or that the traction weights are too heavy. Realigning the client should be the initial response as it can help alleviate the pain by ensuring proper alignment. Asking the client to wiggle their toes may not address the underlying issue causing the pain. Removing traction weights should never be done unless specifically ordered by the healthcare provider as it can affect the traction's effectiveness. Medicating the client with analgesics should only be considered after attempting to address the cause of the pain, which in this case, is realignment.
3. Which sign might a healthcare professional observe in a client with a high ammonia level?
- A. coma
- B. edema
- C. hypoxia
- D. polyuria
Correct answer: A
Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.
4. Which situation is an example of the use of evidence-based practice in the delivery of client care?
- A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
- B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
- C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
- D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab
Correct answer: C
Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.
5. The LPN is preparing to clean a client's PEG tube.The following tasks should the nurse perform EXCEPT?
- A. Gently remove crusty drainage from the site.
- B. Pull the tube in multiple directions to ensure it is secure.
- C. Thoroughly dry the skin around the tube site with a clean towel.
- D. Use mild soap to clean around the tube site.
Correct answer: B
Rationale: When cleaning a client's PEG tube, the nurse should perform tasks that focus on gentle cleaning and avoiding potential irritants. Choice A is correct as gently removing crusty drainage helps maintain hygiene. Choice C is important to prevent skin irritation and infection. Choice D is appropriate for cleaning the area. Choices B and D are incorrect. Choice B is incorrect because pulling the tube in multiple directions can lead to dislodgement or injury. Choice B is incorrect as talcum powder may irritate the stoma, and it is generally not recommended near PEG tubes.
