The nurse is caring for a client with a spinal cord injury at C3. The nurse notices on the cardiac monitor a heart rate of 30 beats per minute & upon assessment of the patient, a change in mental status. What medication does the nurse anticipate will be ordered by the physician STAT?
Atropine 1mg IV push
Epinephrine 1 mg (1:10,000) IV X1
Adenosine 6 mg IV push
Milrinone 50 mcg/kg IV push
The Correct Answer is A
A. Atropine 1 mg IV push
A C3 spinal cord injury disrupts sympathetic control, causing bradycardia. Atropine is the first-line treatment for symptomatic bradycardia.
B. Epinephrine 1 mg IV
Epinephrine is used for cardiac arrest, not initial management of bradycardia.
C. Adenosine 6 mg IV push
Adenosine is used for supraventricular tachycardia, not bradycardia.
D. Milrinone 50 mcg/kg IV push
Milrinone is an inotrope used in heart failure, not bradycardia.

Correct Answer is C
Explanation
A. Initial stage of septic shock
Septic shock typically presents with warm, flushed skin in the early phase due to vasodilation. This client has cold and clammy skin, which is more consistent with hypovolemic shock.
B. Refractory stage of obstructive shock
Obstructive shock (e.g., from cardiac tamponade or pulmonary embolism) would present with jugular vein distention, muffled heart sounds, or severe respiratory distress, which are not seen in this case.
C. Progressive stage of hypovolemic shock
The client has classic signs of hypovolemic shock due to fluid loss (nausea, vomiting, diarrhea). The progressive stage is indicated by hypotension, tachycardia, and end-organ dysfunction (altered mental status, cool/clammy skin).
D. Compensatory stage of diabetic shock
"Diabetic shock" is not a standard classification of shock. The compensatory stage would still have an adequate blood pressure due to SNS activation, but this patient already has profound hypotension.
Correct Answer is D
Explanation
A. Continue to monitor the client as a paralytic ileus is possible
Paralytic ileus can occur postoperatively, but sudden severe pain and distension indicate a more serious issue, such as bowel infarction.
B. Administer the PRN stool softener to the client
A stool softener is inappropriate if the client has a possible bowel obstruction or ischemia.
C. Obtain an order to insert a nasogastric tube set to low suction
An NG tube may help relieve distension, but it does not treat the underlying cause. The priority is to notify the surgeon.
D. Report the assessment findings to the surgeon
Absent bowel sounds, severe pain, and distension suggest bowel ischemia, a life-threatening complication requiring immediate surgical intervention.
