1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

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. Which sign might a healthcare professional observe in a client with a high ammonia level?

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.

3. Under what circumstances is the legal right to confidentiality of client information waived?

Correct answer: A

Rationale: The legal right to confidentiality of client information is waived when a court system subpoenas information. This occurs when information is required for legal proceedings to occur, such as through summonses, court orders, or litigation information necessary for the court. Subpoenas are legal orders that compel the disclosure of information. The other choices do not inherently waive the legal right to confidentiality. A family member's request for health care information would typically require the client's consent or fall under specific legal exceptions. A living will dictates end-of-life care preferences but does not necessarily waive confidentiality. Lastly, the declaration of incompetence may impact decision-making capacity but does not automatically waive confidentiality.

4. What is the most appropriate feeding method for a client who is unable to swallow?

Correct answer: B

Rationale: Nasogastric feedings are the most appropriate feeding method for a client who is unable to swallow. Providing nothing by mouth can lead to nutritional deficiencies, while clear liquids might cause aspiration. Total parenteral nutrition is not necessary if the gastrointestinal tract is functional. Nasogastric feedings are preferred as they can safely provide nutrition without the risks associated with not eating or aspirating.

5. To remove hard contact lenses from an unresponsive client, what should the nurse do?

Correct answer: D

Rationale: When removing hard contact lenses from an unresponsive client, the nurse should ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens. This approach helps prevent scratching the cornea. Gently maneuvering the upper and lower eyelids assists in loosening the lens for easy removal. Options A, B, and C are incorrect because irrigating the eye, grasping the lens, or wearing sterile gloves are not recommended methods for removing hard contact lenses. It is crucial to handle the situation delicately to avoid causing harm or discomfort to the client.
