1. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?
- A. Lactic acid
- B. Ammonia
- C. Albumin
- D. Lactase
Correct answer: B
Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.

Rationale: Indomethacin (Indocin) is an NSAID that can aggravate acute gastritis and should be questioned.
