Nursing Elites

1. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

• A. Assessing visual acuity
• B. Inspecting the eyelids for ptosis
• C. Assessing pupil constriction
• D. Assessing ocular movements

Correct answer: A

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.

2. Intramuscular (IM) phytonadione (vitamin K) 0.5 mg is prescribed for a newborn. After the medication is prepared, in which anatomic site does the nurse administer it?

• A. Rectus femoris muscle
• B. Deltoid muscle
• C. Gluteal muscle
• D. Vastus lateralis muscle

Correct answer: D

Rationale: Vitamin K is administered to newborn infants to help prevent hemorrhagic disease. The best site for intramuscular injection in infants is the vastus lateralis muscle. This site is preferred due to its location away from the sciatic nerve, femoral artery, and vein, reducing the risk of complications. The rectus femoris muscle may be used if necessary; however, it is less favorable than the vastus lateralis due to its proximity to vital structures, making injections there more hazardous. The deltoid muscle is not typically used for IM injections in newborns. The gluteal muscles should be avoided until the child has been walking for at least a year, as they are poorly developed and close to the sciatic nerve.

3. When testing the function of the oculomotor, trochlear, and abducens nerves, which parameter does a nurse check to determine their function?

• A. Tongue symmetry
• B. Eye movements
• C. Facial symmetry
• D. Corneal reflex

Correct answer: B

Rationale: The correct answer is B: Eye movements. When assessing the oculomotor, trochlear, and abducens nerves, evaluating eye movements is crucial. This assessment includes checking the pupils for size, regularity, equality, light reactions, accommodation, and extraocular movements in various gaze positions. Tongue symmetry is primarily used to evaluate cranial nerve XII (hypoglossal nerve) function. Facial symmetry is a key indicator of cranial nerve VII (facial nerve) function. The corneal reflex assesses sensory afferents in cranial nerve V (trigeminal nerve) and motor efferents in cranial nerve VII (facial nerve).

4. A nurse preparing to examine a client’s eyes plans to perform a confrontation test. The nurse tells the client that this test measures which aspect of vision?

• A. Near vision
• B. Color vision
• C. Distant vision
• D. Peripheral vision

Correct answer: D

Rationale: The correct answer is D: Peripheral vision. The confrontation test is a gross measure of peripheral vision. It compares the client’s peripheral vision with the nurse’s, assuming that the nurse’s vision is normal. During the test, the nurse positions themselves at eye level with the client, about 2 feet away, and directs the client to cover one eye with an opaque card. The nurse covers the eye opposite the client’s covered one and slowly moves a target (like a pencil) from the periphery in several directions. The client is asked to indicate when they see the target, which should coincide with when the nurse sees it. Near vision is tested using a handheld vision screener with various sizes of print, color vision with the Ishihara test, and distant vision with a Snellen chart. Therefore, choices A, B, and C are incorrect as they do not measure peripheral vision, which is the focus of the confrontation test.

5. The school nurse is conducting health screenings on schoolchildren. During the screening, she identifies a child with the behavioral characteristics of attention deficit disorder. Which of the following behaviors is consistent with this disorder?

• A. slow speech development
• B. overreaction to stimuli from the surroundings
• C. inability to carry on a conversation
• D. concrete thinking

Correct answer: B

Rationale: The correct answer is 'overreaction to stimuli from the surroundings.' Children with attention deficit disorder often exhibit hypersensitivity to stimuli, leading to overreactions. Slow speech development is not a hallmark of attention deficit disorder; it is more associated with other learning disabilities. While children with this disorder may have difficulty focusing, they can usually carry on a conversation. Concrete thinking is not a common characteristic of attention deficit disorder, as individuals with this disorder may struggle with abstract thinking and impulsivity.
