A nurse is reinforcing teaching with a client who has neutropenia. Which of the following instructions should the nurse include in the teaching?

Choice A rationale Gardening poses a significant risk to clients with neutropenia because soil contains high concentrations of opportunistic pathogens like Aspergillus and Serratia. Neutropenia is defined as an absolute neutrophil count less than 1500 cells/mm, while severe risk occurs below 500 cells/mm. When the immune system is compromised, even minor exposure to environmental molds and bacteria found in dirt or stagnant water can lead to life-threatening fungal infections or septicemia that the body cannot fight. Choice B rationale Fresh fruits and vegetables are often restricted in a neutropenic diet because they can harbor gram-negative bacteria, such as Pseudomonas aeruginosa, on their surfaces. For a client with a low white blood cell count, these normally harmless microbes can cause severe gastrointestinal or systemic infections. Instead, clients should consume cooked foods, where heat has neutralized potential pathogens. All produce must be thoroughly washed and peeled if consumed, though many facilities recommend avoiding raw produce entirely. Choice C rationale Taking a temperature only once a week is insufficient for a neutropenic client. Fever is often the only sign of infection when the inflammatory response is diminished. Clients must monitor their temperature daily, or even more frequently if feeling unwell, and report any reading above 38 degrees Celsius or 100.4 degrees Fahrenheit immediately. Delays in identifying a febrile neutropenic episode can result in rapid clinical deterioration because the body lacks the neutrophils to contain the infection. Choice D rationale Avoiding crowded places is a critical intervention to reduce the risk of exposure to airborne or droplet-transmitted pathogens. In individuals with neutropenia, the lack of mature white blood cells means they cannot effectively mount a defense against common viruses or bacteria spread by others. Reducing contact with large groups or ill individuals minimizes the probability of contracting respiratory infections or other contagious illnesses that could quickly become overwhelming or fatal due to the client's impaired immune status.
