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.

D. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that has been associated with an increased risk of hearing loss, particularly when taken regularly or in high doses.
E. Bumetanide is a loop diuretic that can also have ototoxic effects, especially when used in conjunction with aminoglycoside antibiotics like gentamycin.
F. Heart failure is not associated with hearing loss
Correct Answer is ["11.074"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)
First, calculate the desired dose in units/hr:
- 14 units/kg/hr x 79.1 kg = 1107.4 units/hr
Next, calculate the concentration of heparin in the IV bag:
- 25,000 units / 250 mL = 100 units/mL
Finally, plug the values into the formula:
- Infusion rate = 1107.4 units/hr / 100 units/mL = 11.074 mL/hr
