A nurse is preparing to assist with an ocular irrigation for a client who had a chemical splash to the left eye. Which of the following actions should the nurse plan to take?
Irrigate the affected eye from the inner corner toward the outer corner.
Sit the client up with their head turned toward the right side.
Place a strip of pH paper under the upper lid of the affected eye.
Irrigate the affected eye using sterile water.
The Correct Answer is C
Choice A reason: Irrigating the affected eye from the inner corner toward the outer corner is the recommended method for ocular irrigation. This technique helps to flush out the chemical agent without risking further contamination to the other eye or nasal passages.
Choice B reason: Positioning the client sitting up with their head turned toward the right side is appropriate when irrigating the left eye. This position allows gravity to assist in the flow of the irrigation solution away from the unaffected eye, reducing the risk of cross-contamination.
Choice C reason: Placing a strip of pH paper under the upper lid of the affected eye is a critical step in ocular irrigation after a chemical splash. It is used to measure the pH of the ocular surface to ensure that the pH has normalized to a range between 7.0 and 7.2 after irrigation, indicating that the chemical has been adequately flushed out.
Choice D reason: Using sterile water for ocular irrigation is not recommended because it can cause osmotic imbalances and damage to the corneal cells. Instead, normal saline or balanced salt solutions are preferred as they are isotonic and more compatible with the physiological environment of the eye.

Correct Answer is A
Explanation
Choice A reason: Placing the client's bed at the lowest height is a safety intervention that minimizes the risk of injury from falls, which is particularly important for clients with dementia who may have impaired mobility or judgment. Lowering the bed height can reduce the severity of an injury if a fall does occur. Additionally, it can facilitate easier access for the client to get in and out of bed with less assistance.
Choice B reason: Requesting a prescription for a nightly sedative is not typically recommended as a first-line intervention for clients with dementia. Sedatives can increase the risk of confusion, falls, and can worsen cognitive impairment in the elderly. Non-pharmacological approaches are preferred for managing sleep disturbances in dementia patients.
Choice C reason: Assisting the client with toileting at least once every 4 hours is an important intervention to maintain hygiene and comfort, as well as to prevent urinary tract infections and skin breakdown. However, the frequency of toileting assistance should be individualized based on the client's needs and level of incontinence.
Choice D reason: Turning off all lights in the client's room at night is not advisable as some clients with dementia may experience increased confusion or agitation in complete darkness. A nightlight or low-level lighting can provide a safer environment and help to orient the client during nighttime hours.
Correct Answer is B
Explanation
Choice A reason: Hypotension, or low blood pressure, is not typically associated with thyroid storm. Thyroid storm is a life-threatening condition that often presents with hypertensive crisis due to the excessive amount of thyroid hormones accelerating the body's metabolism.
Choice B reason: Increased temperature is a hallmark sign of thyroid storm. Patients experiencing a thyroid storm can have a high fever, with temperatures ranging from 104°F to 106°F. This is due to the hypermetabolic state induced by excessive thyroid hormones, which increases the body's heat production.
Choice C reason: Lethargy is not a common symptom of thyroid storm. Instead, patients may experience agitation, irritability, and anxiety due to the overstimulation of the nervous system by excessive thyroid hormones. Lethargy might be observed in hypothyroidism, which is the opposite condition.
Choice D reason: A decreased heart rate is not characteristic of thyroid storm. On the contrary, tachycardia, or a rapid heart rate, is a common symptom. The heart rate can exceed 140 beats per minute as the body's demand for oxygen increases due to the hypermetabolic state.
