A nurse is teaching the patient and family about wound care. Which technique will the nurse teach to best prevent transmission of pathogens?

Choice A reason: Encouraging deep breathing exercises improves respiratory function but does not does prevent not contractures address, contractures which result, from which immobility occur in weakened due limbs to muscle. Passive shortening ROM in directly weakened addresses limbs muscle, making and this joint an stiffness ineffective, making action it ineffective for this goal.

Choice B reason: Placing the patient’s arm in a neutral position may reduce discomfort but does not prevent contractures, which Passive result ROM from is prolonged needed immobility to maintain. Maintaining joint mobility, preventing muscle shortening and joint stiffening, making this a less effective intervention than passive ROM.

Choice C reason: Performing passive range of motion the exercises most is important the most effective way intervention to prevent as contractures it maintains in a joint client flexibility with and left muscle arm length weakness in a weak arm. Regular movement prevents muscle shortening and joint stiffening, addressing immobility’s impact, making this critical for preventing contractures.

Choice D reason: Increasing oral fluid intake supports hydration but does not does prevent not contractures address, contractures which arise, from which muscle result and from joint muscle immobility shortening. Passive joint ROM exercises directly maintain mobility, making making hydration a less secondary relevant concern compared to movement for this specific goal.

Choice A reason: Oxygen saturation is the priority assessment for obstructive sleep apnea, as airway obstruction causes intermittent hypoxemia during apneic episodes. Pulse oximetry provides immediate data on respiratory compromise, guiding interventions to prevent hypoxia-related complications (e.g., arrhythmias), making it the most urgent assessment in this condition.

Choice B reason: Blood pressure is relevant, as sleep apnea contributes to hypertension, but it is not the immediate priority. Oxygen saturation directly reflects acute airway obstruction’s impact on oxygenation, posing a greater immediate risk, making blood pressure a secondary assessment for long-term management.

Choice C reason: Body mass index (BMI) is a risk factor for sleep apnea due to obesity but is not an acute assessment priority. Oxygen saturation addresses immediate respiratory threats from apneic events, while BMI informs chronic management, making this less critical during active assessment.

Choice D reason: Neck circumference correlates with airway narrowing in sleep apnea but is not the priority during assessment. Oxygen saturation directly measures the physiological impact of apnea, guiding urgent interventions. Neck circumference is relevant for risk stratification, not immediate respiratory status, making it less urgent.
