The patient has a serious laceration to the arm. The patient receives a local anesthetic mixed with epinephrine prior to suturing. What does the nurse recognize as the rationale for the epinephrine?
 
  1. Constricted blood vessels will extend the duration of action of the drug.
  2. Constricted blood vessels will decrease the amount of pain experienced.
  3. Constricted blood vessels will promote relaxation of the patient.
  4. Constricted blood vessels will result in decreased bleeding.

Question 2

The student nurse does an operating room rotation and notes that many patients receive succinylcholine (Anectine). The student nurse asks the nursing instructor how the drug works. What is the best response by the nursing instructor?
 
  1. The patient will rapidly lose consciousness when this drug is administered.
  2. The patient's cardiac muscle will be impacted as well as the respiratory muscles.
  3. The patient will need to be monitored with an electrocardiogram (ECG).
  4. The patient will need assistance with breathing; it paralyzes respiratory muscles.

Answer to Question 1

Correct Answer: 1
Rationale: Epinephrine is often added to local anesthetics to constrict blood vessels and extend the duration of action of the drug. The amount of vasoconstriction will not significantly decrease bleeding. Vasoconstriction does not decrease pain. Vasoconstriction will not promote relaxation in the patient.

Answer to Question 2

Correct Answer: 4
Rationale: Succinylcholine (Anectine) is a neuromuscular blocker that paralyzes muscles, including those of respiration. Neuromuscular blockers only affect skeletal muscles, not cardiac muscle. Neuromuscular blockers do not affect consciousness. Neuromuscular blockers do not affect cardiac muscle; there is no need to monitor the patient with an electrocardiogram (ECG).

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
