The nurse is caring for a client in neurogenic shock following an overdose of anti-anxiety medication. When assessing this client, the nurse should recognize what characteristic of neurogenic shock?
Signs of sympathetic stimulation
Hypertension
Cool, moist skin
Bradycardia
The Correct Answer is D
A. Neurogenic shock is characterized by the loss of sympathetic tone, leading to parasympathetic predominance. Therefore, signs of sympathetic stimulation, such as tachycardia or sweating, are not present.
B. Neurogenic shock typically causes hypotension, not hypertension, due to vasodilation and decreased systemic vascular resistance.
C. Cool, moist skin is more commonly seen in hypovolemic or septic shock due to peripheral vasoconstriction. In neurogenic shock, vasodilation leads to warm, dry skin.
D. Bradycardia is a hallmark of neurogenic shock due to unopposed parasympathetic stimulation resulting from the loss of sympathetic nervous system control.

Correct Answer is B
Explanation
A. Consulting with a healthcare provider before taking over-the-counter medications is appropriate, as some medications can affect blood glucose levels or interact with diabetes medications.
B. It is crucial for clients with diabetes to continue taking insulin during illness, even if they are unable to eat. Insulin needs may increase due to stress or infection, and not taking insulin could lead to hyperglycemia or diabetic ketoacidosis. Checking blood sugar every 2 hours is correct, but insulin should not be omitted.
C. Calling the doctor if the illness lasts longer than 2 days is a good practice, as prolonged illness can affect diabetes management and may require medical intervention.
D. Calling the doctor if blood sugar is over 250 mg/dL or if there is protein in the urine is appropriate, as these conditions can indicate complications that need medical attention.
Correct Answer is D
Explanation
A. DKA occurs due to a significant deficiency of insulin rather than issues with cell response to insulin. The condition leads to high blood glucose and ketone production because there is not enough insulin to regulate glucose levels effectively.
B. DKA is primarily associated with diabetes mellitus type 1, not type 2. It can occur due to a lack of insulin and is not solely caused by illness, although illness can exacerbate it.
C. DKA is not limited to clients with diabetes mellitus type 1 who experience septic shock. It can occur in anyone with type 1 diabetes due to severe insulin deficiency, though septic shock can complicate the condition.
D. DKA results from a complete absence of insulin, which is characteristic of poorly controlled or undiagnosed diabetes mellitus type 1. This insulin deficiency leads to elevated blood glucose levels and ketone formation.
