Question 4 of 5
The nurse is performing an assessment on a client who is cachectic and has developed an enterocutaneous fistula following surgery to relieve a small bowel obstruction. The client's total protein level is reported as 4.5 g/dl. Which of the following would the nurse anticipate?
Correct Answer: C
Rationale:
Total parenteral nutrition (TPN) will be started. The client is not absorbing nutrients adequately as evidenced by the cachexia and low protein levels. (A normal total serum protein level is 6.0-8.0 g/dl.) TPN will promote a positive nitrogen balance in this client who is unable to digest and absorb nutrients adequately.

A nurse is caring for a 2-year-old with a new diagnosis of strabismus. Which intervention should the nurse anticipate?
Correct Answer: D
Rationale: Patching the unaffected eye strengthens the weaker eye in strabismus by forcing its use, a common non-surgical treatment in children. Laser surgery is not typically used, eye drops are irrelevant, and intraocular pressure measurement is for glaucoma, not strabismus.
