A nurse is caring for a client who has heart failure and a potassium level of 2.4 mEq/L. The nurse should identify which of the following medications as contributing to this lab value?

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 : The statement is correct; even with sterile precautions, there is a risk of infection. It's important for clients to understand this risk and recognize signs of infection early¹.

Choice B reason : This statement is incorrect and indicates a misunderstanding. The volume of the output solution should be equal to or slightly less than the input solution due to fluid removal from the body¹.

Choice C reason : The fluid from the abdomen should indeed be clear or slightly yellow. Cloudy or discolored fluid can indicate an infection or other complication¹.

Choice D reason : Using a microwave to warm the solution is not recommended as it can lead to uneven heating and potentially damage the solution. The solution should be warmed to body temperature using a warming device designed for this purpose¹³.
