The nurse is evaluating outcomes for a patient with insomnia. Which key principle will the nurse consider during this process?
Effective interventions are the best evaluators of sleep.
The patient is the best evaluator of sleep.
Observations of the patient are the best evaluators of sleep.
The nurse is the best evaluator of sleep.
The Correct Answer is B
Choice A reason: Effective interventions (e.g., sedatives) improve sleep but are not evaluators. Insomnia, a disruption of sleep-regulating brain regions like the hypothalamus, is best assessed by patient-reported sleep quality. Interventions address neurotransmitter imbalances (e.g., GABA), but outcomes rely on subjective patient experience, not the intervention itself, making this incorrect.
Choice B reason: The patient is the best evaluator of sleep, as insomnia is subjective, involving perceived sleep quality and duration. Patient reports reflect hypothalamic regulation of sleep-wake cycles and neurotransmitter activity (e.g., melatonin). Subjective data, like feeling rested, provide the most accurate outcome evaluation, aligning with patient-centered care principles, making this correct.
Choice C reason: Nurse observations (e.g., restlessness) provide objective data but are less accurate than patient reports for insomnia. Sleep quality depends on subjective experience, influenced by brain regions like the reticular activating system. Observations may miss subtle sleep disturbances, making patient self-assessment the most reliable evaluator of insomnia outcomes, rendering this incorrect.
Choice D reason: The nurse is not the best evaluator of sleep, as insomnia is a subjective condition. Nurses can observe behaviors, but only patients report perceived sleep quality, reflecting circadian rhythm regulation and neurotransmitter balance. Objective assessments may overlook patient-specific experiences, making patient self-evaluation critical for accurate insomnia outcome assessment, so this is incorrect.

Correct Answer is C
Explanation
Choice A reason: Assessing involves collecting data, like vital signs or skin condition, to identify patient needs. Turning a client every 2 hours follows an established plan to prevent pressure ulcers, not data collection. Assessment informs care plans, but turning is an action, not an evaluation of physiological status, making this incorrect.
Choice B reason: Planning involves setting goals and interventions, like scheduling turns to prevent pressure ulcers. Turning a client every 2 hours is executing that plan, not creating it. Planning addresses skin integrity and tissue perfusion needs, but the act of turning is the implementation phase, making this an incorrect choice.
Choice C reason: Implementing is the execution of the care plan, such as turning a client every 2 hours to prevent pressure ulcers. This action maintains skin integrity by reducing pressure on tissues, promoting blood flow and oxygenation. It follows the plan’s directives, aligning with the nursing process’s action phase, making this the correct choice.
Choice D reason: Evaluating assesses the effectiveness of interventions, like checking skin integrity after turning. Turning a client every 2 hours is the intervention itself, not its evaluation. Evaluation measures outcomes, like reduced pressure ulcer risk, but the act of turning is implementation, addressing tissue perfusion, making this incorrect.
Correct Answer is A
Explanation
Choice A reason: Administering eye drops to the lower conjunctival sac ensures optimal drug absorption and minimizes corneal irritation. The conjunctival sac, a mucous membrane, allows medication to spread across the eye surface, treating conjunctivitis by targeting bacterial or inflammatory processes. This method avoids systemic absorption via the nasolacrimal duct, enhancing local efficacy and safety.
Choice B reason: Dropping medication onto the cornea risks irritation or injury, as the cornea is a sensitive, avascular tissue responsible for light refraction. Conjunctivitis treatment requires medication to contact the conjunctiva, not the cornea directly. This method could cause discomfort and reduce drug efficacy, as it does not target the inflamed conjunctival tissue.
Choice C reason: The sclera by the outer canthus is not ideal for eye drop administration. The sclera, a tough connective tissue, has poor drug absorption compared to the conjunctival sac. Drops placed here may run off, reducing contact with the inflamed conjunctiva in conjunctivitis, leading to ineffective treatment and potential waste of medication.
Choice D reason: The sclera by the inner canthus is near the nasolacrimal duct, increasing the risk of systemic drug absorption rather than local treatment of conjunctivitis. Drops should target the lower conjunctival sac to ensure contact with the inflamed tissue, maximizing therapeutic effect while minimizing systemic side effects like tachycardia from certain medications.
