When caring for a patient with Alzheimer's disease, the nurse would assess the patient for which two common infection-related complications due to chronic dementia?

Choice A reason: Shivering can be a response to various conditions, including cold temperatures or fever, but it is not a direct indicator to discontinue suctioning. While it may be concerning, it does not specifically suggest a problem caused by the suctioning procedure.

Choice B reason: Decreased SpO₂ (oxygen saturation) is a critical sign that the patient is not getting enough oxygen. This condition requires immediate attention, and suctioning should be stopped to assess and address the cause of the hypoxia. Continuing to suction can exacerbate respiratory distress and further lower oxygen levels.

Choice C reason: Absence of coughing is a sign that the patient's airway may be compromised or that the suctioning is too aggressive, potentially leading to further complications. Coughing is a protective reflex that helps clear the airway, and its absence indicates that the airway is not adequately protected, warranting cessation of suctioning.

Choice D reason: Development of dysrhythmias (irregular heartbeats) during suctioning is a serious concern. Dysrhythmias can indicate that the patient is experiencing significant physiological stress or that the vagus nerve is being stimulated, which can impact heart function. Immediate discontinuation of suctioning is necessary to prevent cardiac complications and to stabilize the patient's condition.

Choice E reason: Increased blood pressure, while indicative of stress or pain, is not an immediate indicator to stop suctioning. It should be monitored and addressed, but it does not pose the same immediate risk as decreased oxygen saturation or dysrhythmias.

Choice A reason: NPH (Humulin N) is an intermediate-acting insulin that is used to control blood sugar levels throughout the day, not specifically for mealtime coverage. It is typically administered twice a day.

Choice B reason: Detemir (Levemir) is a long-acting insulin that provides basal insulin coverage. It helps maintain blood sugar levels stable over a 24-hour period and is not intended for controlling post-meal blood sugar spikes.

Choice C reason: Lispro (Humalog) is a rapid-acting insulin used for mealtime coverage. It is designed to be taken just before or immediately after a meal to control the sudden rise in blood sugar levels that occurs after eating.

Choice D reason: Glargine (Lantus) is a long-acting insulin that provides basal insulin coverage, helping to maintain steady blood glucose levels throughout the day and night. It is not used for mealtime blood sugar control.
