Which laboratory results should the nurse closely monitor in a client who has end-stage renal disease (ESRD)?

Choice A reason: This is the correct answer because applying the client's positive airway pressure device is the most important intervention for the nurse to implement before leaving the client. Positive airway pressure device is a treatment that delivers pressurized air through a mask or nasal prongs to keep the upper airway open and prevent apnea episodes during sleep. Obstructive sleep apnea is a condition that causes repeated interruptions in breathing due to partial or complete collapse of the upper airway during sleep. The nurse should ensure that the device is fitted properly and functioning well.

Choice B reason: Elevating the head of the bed to a 45 degree angle is not a sufficient intervention for the nurse to implement before leaving the client. Elevating the head of the bed can help reduce snoring and improve breathing by preventing the tongue and soft palate from falling back and obstructing the airway. However, it may not be enough to prevent apnea episodes in clients with obstructive sleep apnea, especially if they have other risk factors such as obesity, enlarged tonsils, or nasal congestion. The nurse should also use other interventions such as positive airway pressure device, weight loss, or surgery.

Choice C reason: Removing dentures or other oral appliances is not a relevant intervention for the nurse to implement before leaving the client. Dentures or other oral appliances are devices that replace missing teeth or improve dental alignment. They may help improve speech, chewing, and appearance, but they do not have a direct impact on obstructive sleep apnea. The nurse should instruct the client to remove dentures or other oral appliances before going to bed to prevent discomfort, infection, or damage.

Choice D reason: Lifting and locking the side rails in place is not a necessary intervention for the nurse to implement before leaving the client. Side rails are bars that attach to the sides of the bed frame to prevent falls or injuries. They may provide safety and security for some clients, but they may also pose risks such as entrapment, strangulation, or agitation. The nurse should assess the need for side rails on an individual basis and consider alternative measures such as bed alarms, low beds, or floor mats.

Choice A reason: Administering a half dose now is not a safe instruction for the nurse to provide, as this can result in overdosing or underdosing the infant, depending on how much of the medicine was absorbed or expelled. This is a contraindicated choice.

Choice B reason: Giving another dose is not a prudent instruction for the nurse to provide, as this can cause digoxin toxicity, which can be life-threatening for the infant. This is another contraindicated choice.

Choice C reason: Mixing the next dose with food is not a relevant instruction for the nurse to provide, as this does not address the current situation and can affect the absorption and effectiveness of digoxin. This is a distractor choice.

Choice D reason: Withholding this dose is a sensible instruction for the nurse to provide, as this can prevent adverse effects and allow the infant's serum digoxin level to be checked before giving another dose. Therefore, this is the correct choice.
