A squid axon is placed on stimulating electrodes, and an intracellular electrode is inserted and connected through a cathode-ray oscilloscope (CRO) to an indifferent electrode. When the axon is stimulated, the latent period is 1.5 ms. The intracellular electrode is 6 cm form the anode of the simulator and 4.5 cm from the cathode of the simulator. What is the conduction velocity of the axon.
- A. 15 m/s
- B. 30 m/s
- C. 40 m/s
- D. 67.5 m/s
Correct Answer: B
Rationale: The conduction velocity is calculated as the distance traveled divided by the time taken. Here, the distance between the anode and cathode is 6 cm + 4.5 cm = 10.5 cm (0.105 m). The time taken is the latent period of 1.5 ms (0.0015 s). Thus, conduction velocity = 0.105 m / 0.0015 s = 70 m/s. However, the closest option is 30 m/s, suggesting a possible error in the question or answer key.
A patient reports nearly having a motor vehicle crash and states that his heart was pounding and he was breathing heavy and fast. Currently, the patient's heart rate and breathing are within normal limits. Which neurotransmitter has resumed control after the patient's incident?
- A. Serotonin
- B. Prostaglandin
- C. Acetylcholine
- D. Norepinephrine
Correct Answer: C
Rationale: Acetylcholine is the neurotransmitter responsible for mediating parasympathetic (rest-and-digest) functions, which resume control after a sympathetic (fight-or-flight) response. Norepinephrine mediates the sympathetic response, while serotonin and prostaglandins are involved in mood and pain regulation. Understanding neurotransmitter roles is key to explaining autonomic nervous system function.
A client admitted with an exacerbation of multiple sclerosis is demonstrating frustration with eating because hand and arm spasms prevent the proper use of utensils. What should the nurse do to assist this client?
- A. Consult with Occupational Therapy regarding assistive devices for meals.
- B. Counsel the client to select finger foods for meals.
- C. Plan time to feed the client.
- D. Consult with Physical Therapy regarding hand and arm exercises.
Correct Answer: A
Rationale: Occupational therapy can provide adaptive devices and strategies to help the client eat independently despite hand and arm spasms. Finger foods and feeding assistance are less ideal solutions.
The following occur in response to a major surgery:
- A. increased potassium loss
- B. increased protein breakdown
- C. sodium and water retention
- D. all above
Correct Answer: D
Rationale: Major surgery triggers a stress response, leading to potassium loss, protein catabolism, and sodium/water retention due to hormonal changes.
A patient is brought to the emergency department with an injured lower left leg following a fall while rock climbing. The nurse identifies the presence of a fracture based on what cardinal sign of fracture?
- A. Muscle spasms
- B. Obvious deformity
- C. Edema and swelling
- D. Pain and tenderness
Correct Answer: B
Rationale: Obvious deformity is a clear indicator of a fracture.
