A nurse is caring for a child who has otitis media with effusion. The nurse should identify that which of the following manifestations indicates a tympanic membrane rupture?

Choice A reason: Verifying the conductive gel pads is important but should be done before the command "CLEAR!" is given.

Choice B reason: Stepping away from the bed and ensuring others have done the same is crucial for safety. It prevents accidental electrical shock to anyone touching the patient or bed during defibrillation.

Choice C reason: Shutting off the intravenous infusion is not necessary during defibrillation. It does not pose a safety risk in this context.

Choice D reason: Shutting off the mechanical ventilator is not necessary during defibrillation and could compromise the patient's ventilation status.

Choice A reason: Hyperopia, also known as farsightedness, is a condition where distant objects can be seen more clearly than near objects. It is caused by the eyeball being too short or the cornea having too little curvature. In this scenario, the client's ability to adjust and focus on near and distant objects is not indicative of hyperopia.

Choice B reason: Photophobia is an increased sensitivity to light. It can be caused by various eye conditions, infections, or even migraines. The client's ability to focus on objects at different distances does not correlate with sensitivity to light.

Choice C reason: Myopia, or nearsightedness, is the opposite of hyperopia. Individuals with myopia can see near objects clearly but have difficulty focusing on distant objects. The client's ability to focus on both near and far objects rules out myopia.

Choice D reason: Accommodation is the process by which the eye adjusts its focus from near to distant objects (or vice versa). This involves changes in the shape of the lens, controlled by the ciliary muscles. The client's ability to focus on objects at varying distances correctly describes the accommodation process, making it the appropriate answer.
