A nurse is teaching a client who has a new prescription for lovastatin. Which of the following diagnostic tests should the nurse instruct the client to complete before starting the medication?

Choice A rationale:

Completely irrigating one eye before irrigating the second eye is the correct action to take when a client receives a chemical splash on their face. This approach helps prevent the potential spread of the chemical from one eye to the other. Irrigation should be done immediately to flush out the chemical and minimize its harmful effects.

Choice B rationale:

Informing the client to blink their eyes rapidly during the irrigation process is not recommended. Blinking may exacerbate the dispersion of the chemical and could lead to further damage to the eyes. Instead, the client should keep their eyes open during irrigation.

Choice C rationale:

Delaying the irrigation process until the type of chemical in the eyes is identified is not appropriate. Time is critical in minimizing the impact of the chemical on the eyes. Immediate irrigation is essential, regardless of the type of chemical, to remove the substance from the eyes.

Choice D rationale:

Asking the client to count the number of fingers held up by the nurse before irrigating their eyes is not relevant in this situation. The priority is to initiate immediate irrigation to remove the chemical from the eyes. Assessing the client's visual acuity can be done later in the evaluation process after the eyes have been irrigated.

Choice A rationale:
Assessing the need for oral suction every 4 hours is essential in maintaining airway patency and preventing complications associated with excessive secretions. This is an appropriate action and does not require clarification.
Choice B rationale:
Checking the ventilator settings every 12 hours is necessary to ensure that the mechanical ventilation is providing adequate support for the client's respiratory needs. This prescription is appropriate and does not need clarification.
Choice C rationale:
Keeping the head of the client's bed elevated at 30° is important in preventing aspiration and ventilator-associated pneumonia. This position helps promote optimal lung expansion and improves oxygenation in ventilated clients.
Choice D rationale:
Performing oral hygiene using an alcohol-based oral rinse is not recommended for clients receiving mechanical ventilation. Alcohol-based products can be harmful if aspirated and may disrupt the normal oral flora, leading to complications. The nurse should use a non-alcohol-based oral rinse or foam swabs instead.
