Question 1 of 5

Which client should the nurse place in a private room with protective (neutropenic/reverse) isolation?

What is protective (neutropenic) isolation?

It is used for very low neutrophil counts, such as after chemotherapy or stem cell transplant. The guiding principle is keeping organisms away from a patient who cannot fight infection.

Key points to remember

  • Indicated when the absolute neutrophil count is low, generally below 1,000 and especially below 500 cells/mm3.
  • A positive-pressure room with HEPA filtration helps keep airborne organisms out.
  • No fresh flowers, standing water, or raw fruits and vegetables that can harbor bacteria or fungi.
  • Strict hand hygiene by all who enter is the most important protective measure.
  • Anyone with a current infection or recent live-vaccine should not enter the room.

Nursing priorities

  1. Perform meticulous hand hygiene before all patient contact.
  2. Screen and exclude visitors or staff with any signs of illness.
  3. Remove fresh flowers, plants, and standing water from the room.
  4. Provide a low-microbial diet by avoiding raw produce and undercooked foods.
  5. Monitor temperature closely; fever may be the only sign of serious infection.

Labs & values

Absolute neutrophil count: normal about2,500-6,000 cells/mm3; neutropenia below 1,500; severe below 500
WBC: normal5,000-10,000 cells/mm3

Patient teaching

  • Avoid crowds, sick contacts, and gardening or handling soil while counts are low.
  • Report fever, chills, or sore throat immediately rather than waiting.
  • Wash hands often and avoid raw or undercooked foods.

Red flags: report now

  • Report any temperature of 100.4 F (38 C) or higher at once as a possible neutropenic emergency.
  • Never allow live plants, fresh flowers, or ill visitors into the room.
  • Avoid invasive procedures and rectal temperatures or suppositories that breach barriers.
