Nursing Elites

1. 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?

• A. Trochlear nerve
• B. Abducens nerve
• C. Trigeminal nerve
• D. Oculomotor 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.

2. 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.' If an 11-12-month-old child is unable to pull to a standing position, it can indicate a risk for developmental dysplasia of the hip. By 15 months of age, children should be walking, so delayed standing can be a red flag. The Trendelenburg sign is associated with gluteus medius muscle weakness, not hip dysplasia, making choice C incorrect. The Ortolani sign is used to detect congenital hip subluxation or dislocation, not developmental dysplasia, making choice D incorrect.

3. 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.

4. What is the most appropriate initial action for a newborn infant with low blood glucose?

• A. Ask the registered nurse to draw another blood sample in 2 hours and repeat the test
• B. Contact the healthcare provider
• C. Contact the registered nurse
• D. Document the results in the newborn's medical record

Correct answer: C

Rationale: The blood glucose level for a newborn infant should remain greater than 40 mg/dL to prevent permanent brain damage. When dealing with low blood glucose in a newborn, the most appropriate initial action is to contact the registered nurse. The nurse will obtain prescriptions regarding feeding the infant with low blood glucose and follow agency policies on feeding infants in such conditions. It is common practice to feed the infant if the glucose level is 40 mg/dL or less. Asking the registered nurse to draw another blood sample in 2 hours and repeating the test is not the most appropriate immediate action, as timely intervention is crucial in this situation. Contacting the healthcare provider may cause unnecessary delays since the registered nurse is usually the first point of contact for immediate actions in this scenario. Documenting the results in the newborn's medical record is essential, but it is not the initial step in managing low blood glucose in a newborn.

5. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

• A. The fingers curl tightly, and the toes curl forward.
• B. The toes flare, and the big toe is dorsiflexed.
• C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
• D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.
