A nurse is obtaining vital signs from a client who has just been transferred from the PACU to the medical-surgical unit. Which of the following findings should the nurse report?

Tuberculosis is a highly contagious airborne infection caused by Mycobacterium tuberculosis, transmitted through airborne droplet nuclei that remain suspended in the air for prolonged periods. Infection control requires airborne precautions to prevent inhalation of infectious particles by healthcare workers and other clients. Proper personal protective equipment (PPE), specialized room placement, and respiratory protection are essential components of care. Nurses must understand the difference between airborne, droplet, and contact precautions to ensure safety.

Rationale:
A. An N95 respirator is required because it provides a tight seal and filters airborne particles effectively, protecting the nurse from inhaling infectious droplet nuclei. In the care of clients with conditions such as Tuberculosis, airborne precautions mandate use of N95 or higher-level respiratory protection. This is the correct and essential PPE during routine care.

B. Shoe protectors are not routinely required for tuberculosis care because transmission does not occur through footwear contamination. TB is spread via airborne particles, not contact with contaminated floors or fluids. Therefore, shoe covers do not provide meaningful protection in this context.

C. Sterile gloves are not necessary for routine care of a tuberculosis client unless performing a sterile procedure. Standard clean gloves are sufficient for most interactions. TB precautions focus primarily on respiratory protection rather than sterile technique.

D. A surgical mask is not adequate protection for the nurse because it does not effectively filter airborne particles. Surgical masks are used for droplet precautions, not airborne infections like tuberculosis. The client, however, may wear a surgical mask during transport to reduce spread.

Accurate measurement of a tympanic temperature depends on correct alignment of the ear canal with the tympanic membrane to ensure proper infrared detection of body temperature. The procedure requires appropriate positioning of the ear to straighten the external auditory canal, allowing the probe to obtain a reliable reading from the tympanic membrane. Proper technique is especially important in clinical settings where temperature trends are used to monitor infection or inflammatory processes.

Rationale:
A. Positioning the client facing the nurse is not required for tympanic temperature measurement. While proper positioning can improve ease of access, it does not influence the accuracy of the reading. The key determinant of correct technique is proper alignment of the ear canal rather than client orientation.

B. Pointing the probe posteriorly is incorrect because the probe must be directed toward the tympanic membrane, not away from it. Misalignment of the probe can result in inaccurate temperature readings due to improper infrared detection. Correct technique requires gentle insertion following the natural curvature of the ear canal.

C. Pulling the pinna up and back is the correct technique for an adult when measuring tympanic temperature. This action straightens the external auditory canal, allowing the probe to align directly with the tympanic membrane for accurate measurement. Proper positioning ensures reliable detection of infrared heat emitted from the eardrum.

D. Inserting the probe with a straight forward motion is incorrect because the ear canal is not a straight structure. A direct forward insertion can cause discomfort, inaccurate positioning, and unreliable readings. The probe should follow the natural angle of the canal after proper manipulation of the pinna.
