A nurse is teaching the guardian of a newborn about car seat safety.
Which of the following statements by the guardian indicates an understanding of the teaching?

Choice A rationale

Verifying the clarity and color of the eye drops is a critical safety step to ensure the medication has not been compromised. Eye drops should be clear and colorless unless specified otherwise. Any discoloration or particulate matter indicates that the solution may be contaminated or expired and should not be administered, preventing potential harm or infection to the client.

Choice B rationale

Pulling the lower lid down creates a small pocket, or conjunctival sac, which is the proper site for medication administration. This technique prevents the eye drops from immediately flowing out of the eye, allowing for maximum absorption of the medication. It also protects the cornea from direct injury by the applicator, which can be sensitive and easily scratched.

Choice C rationale

Applying gentle pressure to the punctum, the small opening in the corner of the eye, for 30 to 60 seconds after instillation prevents systemic absorption of the medication. This is particularly important for drugs like timolol, a beta-blocker, as systemic absorption can lead to adverse effects on the heart and lungs, such as bradycardia and bronchospasm.

Choice D rationale

Tilting the client's head backward facilitates proper administration by allowing gravity to assist in directing the eye drop into the conjunctival sac. This position also helps to prevent the drop from immediately rolling out of the eye or onto the client's cheek, ensuring the medication is retained in the correct location for therapeutic effect.

Choice E rationale

Administering the prescribed number of drops directly into the conjunctival sac ensures the client receives the correct dosage. The nurse should avoid touching the tip of the dropper to the client's eye or eyelashes to prevent cross-contamination of the bottle. This step is essential for both the therapeutic efficacy and safety of the medication administration. *.

Choice A rationale

A tracheostomy tray is used to perform an emergency tracheostomy. This procedure is not a standard requirement for a client with a thoracotomy and chest tube placement, as the primary respiratory intervention is typically managed via the chest tube and other supportive measures.

Choice B rationale

Montgomery straps are used to secure dressings that require frequent changes, preventing skin irritation from repeated tape removal. They are useful for abdominal wounds or other high-drainage sites but are not a specific or essential piece of equipment for a chest tube.

Choice C rationale

Wire cutters are used to cut stainless steel wires that may be used to secure the sternum after cardiac surgery. A thoracotomy is an incision into the chest wall to access the thoracic cavity; it does not involve sternal wiring.

Choice D rationale

A padded clamp is an essential piece of equipment at the bedside for a client with a chest tube. In the event of a chest tube dislodgement or if the drainage system needs to be changed, the clamp is used to temporarily occlude the tube to prevent a pneumothorax. .
