A client has begun a long-term maintenance therapy with lithium, which has a narrow therapeutic index. Which adverse effect is most important for the nurse to include in the teaching plan?

Choice A reason: Monitoring airway and tongue during a tonic-clonic seizure is critical, as muscle contractions can obstruct the airway or cause tongue biting, leading to hypoxia. Ensuring airway patency prevents respiratory compromise, a life-threatening issue, addressing the physiological priority of oxygenation during seizure-induced neuronal hyperactivity.

Choice B reason: Darkening the room by closing blinds is not a priority during a seizure. Reducing stimuli may help photosensitive epilepsy, but active seizures require airway and safety management. Uncontrolled movements from neuronal discharges pose immediate risks, making airway monitoring and injury prevention more critical than environmental adjustments.

Choice C reason: Placing pillows inside side rails protects the child from trauma during a seizure, as tonic-clonic movements from cortical hyperexcitability risk fractures or head injuries. Padding reduces impact injuries, addressing the physiological need for safety during clonic jerking, ensuring protection against environmental hazards in the seizure setting.

Choice D reason: Asking the mother to release the child prevents harm, as restraint during a seizure can cause fractures or muscle strain by resisting neuronal-driven movements. Allowing free movement in a safe environment reduces injury risk, prioritizing physical safety and preventing complications from external resistance during the seizure.

Choice E reason: Administering an anticonvulsant requires a prescription and is not immediate during an active seizure. While drugs like lorazepam treat prolonged seizures, the nurse prioritizes airway and safety. Only trained personnel with orders can administer medications, making this less urgent than ensuring airway patency and injury prevention.

Choice A reason: Thick, dry, dark areas on heels suggest chronic skin changes, not early pressure ulcers. Persistent redness over bone is the earliest sign (Stage 1). This indicates later damage, per pressure injury staging and prevention protocols in nursing care for immobile clients.

Choice B reason: Broken skin indicates a Stage 2 pressure ulcer, beyond the earliest stage. Persistent redness (Stage 1) signals initial tissue compromise. Broken skin requires intervention but is not the earliest sign, per pressure ulcer assessment and prevention standards in nursing practice.

Choice C reason: Persistent redness over bone is the earliest sign of a Stage 1 pressure ulcer, indicating tissue compromise due to pressure. Early intervention prevents progression in bedrest clients with heart failure, per pressure injury prevention and skin assessment protocols in nursing care.

Choice D reason: A superficial sacral ulcer (Stage 2) is more advanced than persistent redness (Stage 1), the earliest sign. Redness allows earlier intervention to prevent ulceration. Ulcers indicate progression, per pressure ulcer staging and prevention guidelines for immobile clients in nursing.
