Which lobe is most closely associated with visual processing?
- A. frontal
- B. temporal
- C. parietal
- D. occipital
Correct Answer: D
Rationale: The occipital lobe is the primary area of the brain responsible for visual processing. It contains the visual cortex, which processes information from the eyes and interprets it as images. Damage to the occipital lobe can result in visual impairments, such as blindness or difficulty recognizing objects. The occipital lobe works in conjunction with other brain regions to integrate visual information with other sensory inputs.
The corneal stroma:
- A. measures 500 um thick
- B. transmits 90% of the incoming light
- C. derives most of its oxygen from the precorneal tear film
- D. is acellular which accounts for its transparency
Correct Answer: A
Rationale: The corneal stroma is approximately 500 micrometers thick and is responsible for the majority of the cornea's thickness. It transmits most of the incoming light, but its transparency is due to the regular arrangement of collagen fibers and the presence of keratocytes, not because it is acellular.
Which of the following nursing interventions should be done in the case of a client who has a head injury obtained from being thrown off of a motorcycle?
- A. Assess LOC every hour or more often if needed
- B. Put the code cart outside the client's room
- C. Keep the client quiet in bed
- D. Allow one visitor at a time
Correct Answer: A
Rationale: Frequent assessments of LOC are critical to detect worsening neurological status.
Which of the following is the correct sequence in a typical reflex arc:
- A. effector, afferent neuron, integration centre, efferent neuron, receptor
- B. receptor, afferent neuron, integration centre, efferent neuron, effector
- C. effector, efferent neuron, integration centre, afferent neuron, receptor
- D. receptor, efferent neuron, integration centre, afferent neuron, effector
Correct Answer: B
Rationale: The correct sequence in a reflex arc is: receptor detects the stimulus, afferent neuron transmits the signal to the integration center, efferent neuron carries the response signal, and effector produces the response. Therefore, B is the correct answer.
The nurse is preparing to conduct a Romberg test with a patient. For how many seconds should the nurse explain to the patient that the position will need to be held?
- A. 10
- B. 20
- C. 30
- D. 40
Correct Answer: B
Rationale: The Romberg test requires the patient to stand with feet together and eyes closed for 20 seconds. Swaying or loss of balance during this time indicates a positive test. Holding the position for 20 seconds is sufficient to assess balance and proprioception.
