A nurse enters a client's room and sees smoke coming from the bathroom. Which of the following actions should the nurse take first?

Choice A Reason:
Absence of Chvostek's sign is a wrong indication. Chvostek's sign is a twitching of facial muscles in response to tapping the facial nerve and is typically associated with low blood calcium levels (hypocalcemia). It's not directly related to hyperglycemia or high blood sugar levels. Hyperglycemia refers to high blood sugar levels, commonly associated with diabetes mellitus.
Choice B Reason:
Presence of Kussmaul respirations is a right indication. Kussmaul respirations are deep, rapid, and labored breathing patterns often seen in individuals with diabetic ketoacidosis (DKA), a severe complication of diabetes characterized by significantly high blood sugar levels and the presence of ketones in the blood and urine. This type of breathing pattern is the body's attempt to compensate for the acidic state caused by high blood sugar and the buildup of ketones.
Choice C Reason:
Presence of diaphoresis is a wrong indication. Diaphoresis refers to excessive sweating, which can occur due to various reasons such as physical activity, heat, stress, or certain medical conditions. While hyperglycemia can cause symptoms like increased thirst and frequent urination, diaphoresis alone is not a specific indicator of high blood sugar levels.
Choice D Reason:
Absence of urinary ketones is a wrong indication. The presence of urinary ketones indicates the body is breaking down fat for energy, which commonly occurs during periods of insufficient insulin (such as in hyperglycemia or diabetic ketoacidosis). However, the absence of urinary ketones doesn't necessarily rule out hyperglycemia. It's possible for hyperglycemia to be present without ketones in the urine, especially in the early stages or when the body is still managing blood sugar levels without significant ketone production.

Choice A Reason:
Administering a prescribed oral dose of trazodone to the client is correct. Trazodone is sometimes used to manage agitation in patients with Alzheimer's disease, as it has calming effects and can help reduce agitation and anxiety. However, the use of any medication should be based on the client's individualized treatment plan and prescribed by a healthcare provider.
Choice B Reason:
Encouraging ambulation might not be suitable if the client is agitated, as it could potentially escalate the situation or increase the risk of falls or injury. Safety should be a priority, and ambulation might not be advisable during a state of agitation.
Choice C Reason:
Isolating the client in their room is incorrect. Isolating the client might increase feelings of confusion, fear, or distress, potentially worsening the agitation. It's important to engage and support the client rather than isolate them, which can be distressing for someone with Alzheimer's disease.
Choice D Reason:
Applying bilateral wrist restraints to the client is incorrect. The use of restraints should only be considered as a last resort when all other measures have failed and when there's an immediate risk of harm to the client or others. Restraints can be physically and psychologically harmful, leading to increased agitation, anxiety, and potential injury. They should be used only under strict guidelines and with proper authorization when all other interventions have been exhausted.
