A nurse is caring for an adolescent client who has cystic fibrosis.
Which of the following actions should the nurse instruct the client to take prior to initiating postural drainage?

Choice A rationale:

Choosing a palpable and straight vein is essential for a successful IV insertion. A vein that is easily palpable and visible helps ensure that the catheter can be inserted smoothly, reducing the risk of complications such as infiltration or extravasation. Additionally, selecting a straight vein makes the insertion process easier and less painful for the client.

Choice B rationale:

Selecting a site on the client's dominant arm is not a requirement for IV insertion. The choice of arm depends on the individual client's condition, vein accessibility, and the healthcare provider's preference. Both arms can be used for IV insertion based on the client's specific needs.

Choice C rationale:

Applying a tourniquet below the venipuncture site helps distend the veins, making them more visible and accessible. This technique can aid in locating suitable veins for insertion. However, it is crucial to release the tourniquet once the vein is accessed to prevent complications such as thrombosis or hematoma.

Choice D rationale:

Elevating the client's arm prior to insertion can cause veins to collapse, making it more challenging to insert the IV catheter. Gravity can assist in distending the veins, so the arm should be positioned at or slightly below the level of the heart during IV insertion to maintain adequate blood flow.

Choice A rationale:

Preparing to assist with intubation is the appropriate action for a nurse caring for a child with suspected epiglottitis. Epiglottitis is a medical emergency where the airway can become severely compromised due to inflammation of the epiglottis. Intubation ensures a secure airway, allowing the child to breathe and preventing respiratory distress.

Choice B rationale:

Preparing a cool mist tent is not the priority in suspected epiglottitis. While humidified air can provide comfort for respiratory distress, it does not address the potential for airway obstruction. Intubation takes precedence in this critical situation.

Choice C rationale:

Suctioning the child's oropharynx may worsen the condition in suspected epiglottitis. Suctioning can stimulate the epiglottis, triggering a spasm and further obstructing the airway. Intubation is the primary intervention to secure the airway safely.

Choice D rationale:

Obtaining a throat culture is not the immediate action in suspected epiglottitis. While a throat culture may confirm the diagnosis, the priority is securing the airway to prevent respiratory distress and hypoxia.
