A nurse is reviewing the laboratory findings for a client who has idiopathic thrombocytopenic purpura (ITP). Which of the following findings should the nurse expect to be decreased?

Asthma action plans often use a color-coded system to guide management based on peak expiratory flow rate (PEFR) measurements. The zones are typically green (80-100% of personal best), yellow (50-79% of personal best), and red (less than 50% of personal best).

A. The student needs to go to the hospital.

This is not necessarily required when the student is in the yellow zone. The yellow zone indicates caution and the need for intervention, but it does not immediately require hospitalization unless symptoms worsen or do not improve after using the quick-relief inhaler.

B. The nurse should obtain a second expiratory flow rate.

Confirming the peak flow measurement with a second reading ensures accuracy and helps to make informed decisions about the student's asthma management.

C. The student should use his quick-relief inhaler.

In the yellow zone, indicating moderate impairment, the use of a quick-relief (rescue) inhaler is often recommended to relieve symptoms and prevent progression to the red zone.

D. The student's peak flow is 50% to 80% of his best peak flow.

This is the correct range for the yellow zone, indicating moderate impairment. Action is needed to prevent worsening.

E. The student's asthma is not well controlled.

Being in the yellow zone indicates that the asthma is not well controlled and may require adjustments in the long-term management plan, including possible changes to daily controller medications.

A. A room that is within view of the nurses' station: While visibility to the nurses' station is advantageous for monitoring the client, it is not the most critical consideration for a client with active tuberculosis. The priority is to prevent the spread of infectious droplets to other clients and healthcare workers.

B. A room in the ICU: Placing a client with active tuberculosis in the ICU may not be necessary unless there are specific medical reasons requiring intensive care. However, the room assignment should prioritize infection control measures.

C. A room with another nonsurgical client: It is not advisable to place a client with active tuberculosis in a room with another nonsurgical client due to the risk of spreading the infection to a potentially vulnerable individual.

D. A room with air exhaust directly to the outdoor environment: This is the correct answer. The preferred room assignment for a client with active tuberculosis is one with proper ventilation that allows air to be exhausted directly to the outdoor environment. Negative pressure rooms with high-efficiency particulate air (HEPA) filtration are often used to minimize the risk of airborne transmission.
