Identify the correct statement regarding the neural mechanism of pain.
 
  1. Once the pain impulse reaches the spinal cord, neurotransmitters inhibit the signal.
  2. Alpha fibers are wrapped in myelin; C fibers are not.
  3. When tissues are damaged, pain impulses go directly to the brain via alpha and beta fibers.
  4. Myelin is a substance that slows nerve transmission.

Question 2

The patient receives warfarin (Coumadin). The nurse notes that the patient's morning international normalized ratio (INR) is 7. What are the priority nursing interventions at this time?
 
  1. Hold the next dose of warfarin (Coumadin) and repeat the international normalized ratio (INR).
  2. Administer protamine sulfate and hold the next dose of warfarin (Coumadin).
  3. Hold the next dose of warfarin (Coumadin) and contact the physician.
  4. Administer vitamin K and hold the next dose of warfarin (Coumadin).

Answer to Question 1

2
Rationale 1: Once the impulse reaches the spinal cord, neurotransmitters pass the message along to the next neuron.
Rationale 2: The alpha fibers are wrapped in myelin; the C fibers are not.
Rationale 3: A pain impulse travels to the spinal cord via alpha and C fibers.
Rationale 4: Myelin is a lipid substance that speeds nerve transmission.
Global Rationale: A pain impulse travels to the spinal cord via alpha and C fibers. The alpha fibers are wrapped in myelin (a lipid substance that speeds nerve transmission); the C fibers are not. Once the impulse reaches the spinal cord, neurotransmitters pass the message along to the next neuron.

Answer to Question 2

4
Rationale 1: Repeating the international normalized ratio (INR) is appropriate but not the highest priority.
Rationale 2: Protamine sulfate is the antidote for heparin, not warfarin.
Rationale 3: Consulting the physician is appropriate but not the highest priority.
Rationale 4: Vitamin K is the antidote for warfarin (Coumadin) overdose, and its administration is warranted with an international normalized ratio (INR) of 7.
Global Rationale: Vitamin K is the antidote for warfarin (Coumadin) overdose, and its administration is warranted with an international normalized ratio (INR) of 7. Repeating the international normalized ratio (INR) is appropriate, but the patient must receive vitamin K immediately. Protamine sulfate is the antidote for heparin, not warfarin. Consulting the physician is appropriate, but the patient must receive vitamin K immediately.
