A nurse is assessing a client who has chronic emphysema. The client is receiving oxygen at 2 L/min via nasal cannula and is resting with the head of bed elevated to a 45° angle. Which of the following findings should the nurse identify as an early indication of hypoxia?

A. Providing a verbal report of the client's status to a paramedic performing the transfer: Sharing relevant health information with personnel directly involved in the client’s care is appropriate and necessary for continuity of care. This does not constitute a breach of confidentiality because it is directly related to the client’s treatment and transfer.

B. Faxing the client's medical records to the long-term care facility: Sending medical records to the receiving facility ensures that the client’s care can continue without interruption. As long as the transmission is secure and the information is limited to what is necessary, this is an appropriate and legally permissible action.

C. Discussing the client's reaction to the transfer with another staff nurse: Sharing personal information about the client’s emotional response outside of a care-related context is not necessary for treatment or transfer and constitutes a breach of confidentiality. Such discussions should be avoided to protect the client’s privacy.

D. Leaving a phone message for the provider regarding the status of the client's transfer: Communicating with the provider about the client’s care is appropriate. Leaving a message regarding transfer status is relevant to the client’s treatment and does not violate confidentiality, provided the information is limited to necessary clinical details.

A. Influenza immunizations: Administering vaccines is a primary level of prevention because it aims to prevent the onset of disease before exposure occurs. This activity reduces the risk of infection in healthy individuals.

B. Tuberculosis screenings: Screening for tuberculosis is a secondary prevention activity because it involves early detection of disease in asymptomatic individuals. Identifying TB early allows for prompt treatment to prevent progression and transmission.

C. Presentations about safer sex practices: Educational programs promoting safer behaviors are primary prevention because they aim to reduce risk factors and prevent disease before it occurs.

D. Evaluations of bloodborne pathogen policies: Evaluating workplace policies is a tertiary prevention strategy if it focuses on managing and controlling the impact of existing disease or exposure. It does not directly detect or prevent disease in healthy individuals.
