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.

Correct Answer: B

Rationale: Ten seconds is the usual amount of time the nurse should spend for each suction pass. Two seconds is not enough time to effectively remove secretions, while 20 and 30 seconds are too long and could lead to hypoxia and tissue trauma. Therefore, the correct choice is 10 seconds, as it strikes a balance between removing secretions adequately and minimizing the risks associated with prolonged suctioning.

Correct Answer: C

Rationale: Vomiting bile is not typically a sign of internal bleeding but is more commonly associated with issues in the gastrointestinal tract. Signs of internal bleeding include painful or swollen extremities, a tender, rigid abdomen, and bruising. Painful or swollen extremities can indicate bleeding from an extremity injury, a tender, rigid abdomen can signal abdominal bleeding, and bruising can result from blood vessel damage. Therefore, the correct answer is 'C: vomiting bile,' as it is not a typical sign of internal bleeding.

Correct Answer: D

Rationale: Effective delegation depends on clear, concise direction that leaves no room for question or interpretation on the part of the one being delegated to. In this scenario, the most appropriate direction is to ensure the urine specimen is collected promptly and delivered to the lab immediately. Choice A is too vague and does not specify the urgency required. Choice B does not emphasize the immediate need for the specimen to be delivered. Choice C introduces unnecessary medical information that is beyond the scope of a nursing assistant and may cause confusion. Therefore, choice D is the correct answer as it provides clear instructions for immediate action without room for misunderstanding.

Correct Answer: D

Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.
