Question 1 of 5
While assisting with data collection of an adult client, a nurse asks the client to identify various odors. In this technique, which cranial nerve is the nurse assessing?
Correct Answer: C
Rationale: The correct answer is 'Olfactory.' The olfactory nerve is responsible for the sense of smell. Assessing this nerve involves testing the client's ability to identify various odors. Loss of smell, head trauma, abnormal mental status, and suspected intracranial lesions are conditions where testing the olfactory nerve is essential. The optic nerve is evaluated for visual acuity and visual fields. The abducens nerve is usually assessed alongside the oculomotor and trochlear nerves, focusing on pupil size, regularity, light reactions, accommodation, and extraocular movements. The hypoglossal nerve is examined by inspecting the tongue, not by assessing the sense of smell.
Question 2 of 5
While assisting with data collection, the nurse asks the client to close their jaws tightly. Subsequently, the nurse tries to open the closed jaws. In this technique, the nurse is assessing the motor function of which nerve?
Correct Answer: C
Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.
Question 3 of 5
While assisting with data collection regarding the neurological system, the nurse asks the client to puff out both cheeks. Which cranial nerve is the nurse assessing?
Correct Answer: B
Rationale: The correct answer is B: Facial. Assessment of cranial nerve VII (facial nerve) involves noting mobility and symmetry as the client performs various facial movements, including puffing out the cheeks. Cranial nerve IX (glossopharyngeal nerve) and cranial nerve X (vagus nerve) are tested together for different functions. The abducens, oculomotor, and trochlear nerves are assessed together for eye movements and pupil reactions, not cheek puffing.
Question 4 of 5
A nurse is preparing to assess the function of a client's spinal accessory nerve. Which action does the nurse ask the client to take to aid assessment of this nerve?
Correct Answer: C
Rationale: To assess cranial nerve XI (spinal accessory nerve), the examiner checks the sternomastoid and trapezius muscles for equal size. Equal strength is assessed by asking the client to rotate the head forcibly against resistance applied to the side of the chin and by asking the client to shrug the shoulders against resistance. These movements should feel equally strong on the two sides. The client is asked to smile as a test of the function of cranial nerve VII (facial nerve). The client's ability to clench the teeth is used to assess the motor function of cranial nerve V (trigeminal nerve). The client's taste perception is used to assess the sensory function of cranial nerve IX (glossopharyngeal nerve). Therefore, the correct action to assess the spinal accessory nerve is to ask the client to shrug the shoulders against resistance. The other options are used to assess different cranial nerves, making them incorrect choices.
Question 5 of 5
If Ms. Barrett's distance vision is 20/30, which of the following statements is true?
Correct Answer: A
Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.
