Nursing Elites

1. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

2. 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?

• A. Smiling
• B. Clenching the teeth
• C. Shrugging the shoulders against the nurse's resistance
• D. Identifying by taste a substance placed on the back of the tongue

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.

3. A nurse is preparing to assess a client for the presence of the Tinel sign. Which action does the nurse take to elicit this sign?

• A. Testing for the strength of each muscle joint
• B. Percussing at the location of the median nerve
• C. Checking for repetitive movements in the joints
• D. Asking the client to flex the wrist 90 degrees while holding the hands back to back

Correct answer: B

Rationale: The Tinel sign is elicited by percussing at the location of the median nerve at the wrist. In carpal tunnel syndrome, this test can produce burning and tingling along the nerve's distribution. Choices A, C, and D are incorrect. Testing for the strength of each muscle joint and checking for repetitive movements in the joints involve different assessments unrelated to the Tinel sign. Asking the client to flex the wrist 90 degrees while holding the hands back to back is associated with the Phalen test, which is another evaluation for carpal tunnel syndrome.

4. Which of the following physical findings indicates that an 11-12-month-old child is at risk for developmental dysplasia of the hip?

• A. refusal to walk
• B. not pulling to a standing position
• C. negative Trendelenburg sign
• D. negative Ortolani sign

Correct answer: B

Rationale: The correct answer is 'not pulling to a standing position.' An 11-12-month-old child not pulling to a standing position may be at risk for developmental dysplasia of the hip. By this age, children typically pull to a standing position, and failure to do so should raise concerns. Refusal to walk is a broader observation and not specific to hip dysplasia. The Trendelenburg sign indicates weakness of the gluteus medius muscle, not hip dysplasia. The Ortolani sign is used to detect congenital subluxation or dislocation of the hip, which is different from developmental dysplasia of the hip.

5. Which of the following vaccines contains a live virus?

• A. varicella
• B. IPV
• C. DTaP
• D. hepatitis B

Correct answer: A

Rationale: The correct answer is varicella. Varicella vaccine contains a live, weakened form of the varicella-zoster virus. Choice B, IPV (inactivated poliovirus vaccine), is an inactivated vaccine, not a live virus vaccine. Choices C and D, DTaP (diphtheria, tetanus, and acellular pertussis vaccine) and hepatitis B vaccine, respectively, do not contain live viruses. Varicella is the only live virus vaccine among the options.
