A nurse is caring for a client who has reported experiencing abuse at home. Which of the following actions should be a priority for the nurse?

Choice A reason : Reducing stimuli is crucial for a patient emerging from a coma, especially after a traumatic brain injury (TBI). Excessive sensory input can overwhelm the patient's already compromised neurological state. The goal is to provide a calm and controlled environment to prevent overstimulation, which can lead to increased intracranial pressure (ICP), agitation, and delayed recovery. Interventions may include minimizing noise, dimming lights, and limiting the number of visitors. It's important to tailor the level of stimuli to the individual patient's response and recovery stage.

Choice B reason : Darkening the room can be part of reducing stimuli, but it is not the sole intervention needed. While a darker environment may help some patients rest, it is not universally applicable and should be considered as one aspect of an overall strategy to reduce stimuli. The nurse must assess the patient's individual needs and responses to determine if darkening the room is beneficial.

Choice C reason : The application of restraints is generally considered a last resort due to the potential for physical and psychological harm. Restraints can increase agitation and disorientation, potentially leading to self-injury or interference with medical devices. The use of restraints requires careful consideration, adherence to protocols, and often legal documentation. Non-pharmacological interventions and environmental modifications should be attempted first to manage restlessness.

Choice D reason : The administration of opioids is not typically indicated solely for restlessness in patients emerging from a coma. Opioids can depress the central nervous system, potentially masking neurological assessments and delaying recovery. They are primarily used for pain management. If restlessness is due to pain, then appropriate analgesia, including opioids, may be considered, but the underlying cause of restlessness should be thoroughly assessed and treated.

Choice A reason : In primary hypothyroidism, the thyroid gland is underactive and does not produce sufficient thyroid hormones. As a result, the pituitary gland releases more TSH to stimulate the thyroid, leading to elevated levels of TSH in the blood⁶⁷⁸.

Choice B reason : Free T3 levels might not be elevated in primary hypothyroidism. Free T3 is the active form of triiodothyronine and could be normal or low depending on the severity and type of hypothyroidism⁶.

Choice C reason : Serum T3 levels are typically not the first indicator to change in primary hypothyroidism and may remain within normal ranges even when TSH is elevated⁶.

Choice D reason : Serum T4 levels are expected to be low in primary hypothyroidism because the thyroid gland is not producing enough of this hormone. However, the initial and most sensitive indicator of primary hypothyroidism is an elevated TSH level⁶.
