A client returned home from an overseas tour of duty and tells the nurse he is always tired. He has a temperature of 99.5°F (37.5°C). His skin is dark bronze, and his urine has a dark color. His hemoglobin level is 9 g/dL; his hematocrit is 49, and red blood cells are 2.75 million/µL. What should the nurse do first?
- A. Initiate an intake and output record.
- B. Place the client on bed rest.
- C. Place the client on contact isolation.
- D. Keep the client out of sunlight.
Correct Answer: B
Rationale: The client's symptoms (fatigue, bronze skin, dark urine, low hemoglobin, and RBC count) suggest hemolytic anemia, possibly due to an infectious or toxic exposure overseas. Placing the client on bed rest is the priority to reduce oxygen demand and prevent further hemolysis while diagnostic evaluation proceeds. Intake/output monitoring, isolation, and sunlight avoidance are not immediate priorities.

- A. Annual digital rectal examination should begin at age 40.
- B. Annual fecal testing for occult blood should begin at age 50.
- C. Individuals should obtain a baseline barium enema at age 40.
- D. Individuals should obtain a baseline colonoscopy at age 45.
Correct Answer: B

Baseline barium enemas or colonoscopies are recommended at age 50. Baseline barium enemas and colonoscopies are not performed on individuals in their 40s unless they recommend the nurse to the need for such diagnostic testing, or are considered to be at high risk.
