A nurse is reinforcing teaching with a client who is scheduled to have a colonoscopy in 1 week. Which of the following client statements indicates an understanding of the teaching?

Rationale:

• Examine the client's nail beds: Assessing nail beds for cyanosis provides visual clues of hypoxia. This is a noninvasive, rapid method to evaluate tissue perfusion and oxygenation. The client's saturations are borderline low despite increasing oxygen.

• Place the client in the supine position: The supine position can reduce lung expansion and worsen hypoxia, especially after sedation. Elevating the head of the bed promotes lung expansion and better diaphragmatic movement.

• Encourage client to perform deep breathing exercises: Deep breathing helps expand alveoli and improves oxygen exchange. It may reduce the need for higher oxygen delivery if the hypoxia is due to shallow respirations after sedation.

• Prepare to administer oxygen via Venturi face mask: The client's O₂ saturation is dropping despite nasal cannula at 5 L/min. A Venturi mask delivers a more precise and consistent oxygen concentration, making it appropriate here.

• Add a humidifier to the oxygen device: Humidification is generally needed for oxygen above 4 L/min over long durations. This client has only been on oxygen for a short time post-procedure, so humidification is not urgently required.

Rationale:

A. A child who was conceived by in vitro fertilization: Children conceived through IVF are typically highly desired and planned for, and families may invest significant emotional and financial resources into their care. This background generally reduces rather than increases the risk of maltreatment.

B. A toddler who has atopic dermatitis: Although chronic conditions can be stressful for caregivers, atopic dermatitis is relatively common and manageable. It does not significantly increase the risk of child abuse or neglect compared to more severe or demanding conditions.

C. An only child: Being an only child does not inherently increase the risk for maltreatment. Risk factors for abuse are more closely associated with caregiver stress, socioeconomic status, substance use, and the presence of physical or cognitive impairments in the child.

D. A school-age child who has cerebral palsy: Children with disabilities like cerebral palsy are at higher risk for maltreatment due to the physical, emotional, and financial stress their care may place on caregivers. These children often require more supervision and support, which can lead to frustration or neglect in high-risk environments.
