A nurse is collecting data from a client who has hyponatremia. Which of the following findings should the nurse expect?

A. Collect a sputum sample: Attempting to collect a sputum sample can trigger a gag or cough reflex, potentially causing complete airway obstruction in a child with epiglottitis. This action is unsafe in a suspected airway emergency.

B. Obtain a specimen for throat culture: Throat culture requires direct visualization or manipulation of the throat, which can provoke laryngospasm or airway compromise in epiglottitis. Invasive procedures should be avoided until the airway is secured.

C. Determine the preschooler's oxygen saturation level: Assessing oxygen saturation is a noninvasive way to monitor respiratory status and detect hypoxia early. It provides critical information on the child’s oxygenation without manipulating the airway, making it a safe first action.

D. Inspect the preschooler's tonsils for edema: Direct inspection of the throat can precipitate sudden airway obstruction in epiglottitis. Visual examination should be avoided until the child is in a controlled setting with airway management available.

A. Wrap the sleeve loosely around the client's lower leg: The sleeve should fit snugly but comfortably to ensure effective compression. Wrapping it too loosely reduces efficacy in promoting venous return and preventing deep vein thrombosis. Proper fit is essential for device function and patient safety.

B. Measure the circumference of the client's upper leg: Measuring the thigh circumference ensures the correct sleeve size is selected, which is crucial for effective compression and prevention of pressure injury. Accurate sizing allows the device to deliver appropriate pressure without causing discomfort or circulatory compromise.

C. Turn on the mechanical unit prior to applying the sleeve: The device should remain off until the sleeve is properly positioned on the client. Activating it beforehand may result in improper inflation, skin injury, or ineffective compression. Turning it on too early can also startle the client and reduce comfort.

D. Position the client prone to apply the device: The client should be supine or with legs slightly elevated when applying a thigh-length sequential compression device. Prone positioning is unnecessary, uncomfortable, and can complicate proper sleeve placement. Supine positioning facilitates correct alignment and device effectiveness.
