The nurse is testing the function of cranial nerve XI (Spinal accessory nerve). Which finding would the nurse expect if the nerve is intact?

Follows an object with eyes without nystagmus or strabismus

Moves the tongue out midline without tremors or deviation

Moves the head and shoulders against resistance with equal strength

Demonstrates full range of the neck

Answer and Explanation

The Correct Answer is C

A. Follows an object with eyes without nystagmus or strabismus
Cranial nerves III (oculomotor), IV (trochlear), and VI (abducens) control eye movement. CN XI does not control eye movement.

B. Moves the tongue out midline without tremors or deviation
Cranial nerve XII (hypoglossal nerve) controls tongue movement.

C. Moves the head and shoulders against resistance with equal strength
Cranial nerve XI (spinal accessory nerve) controls the sternocleidomastoid and trapezius muscles. If intact, the client can shrug shoulders and turn the head against resistance with equal strength.

D. Demonstrates full range of the neck
Full range of motion in the neck involves multiple muscles, not just those innervated by CN XI.

Correct Answer is B

Explanation

A. Removal of the educating patient to carry an Epipen
While educating the patient about carrying an Epipen is essential in managing anaphylaxis, it is not the primary action in preventing anaphylactic shock before exposure to an allergen.

B. Assess and document for previous allergies and drug reactions prior to medication administration
Identifying and documenting allergies before administering medications or treatments helps prevent exposure to known allergens, reducing the risk of anaphylaxis.

C. Administer diphenhydramine and solumedrol IV at the first sign of allergic symptoms
These medications help in managing allergic reactions but do not prevent anaphylactic shock. Preventive measures focus on avoiding allergen exposure rather than treating symptoms after they occur.

D. Application of a red allergy bracelet on the patient’s upper extremity
This helps alert healthcare providers about allergies, but it does not prevent anaphylactic shock. It is a precautionary step rather than a primary prevention strategy.

A. is expected to be decreased for three to five days. B. will be reduced in the first 24-48 hours and will then increase. C. output will be greatest in the first 24 hours after the burn injury. D. will be elevated due to the amount of intravenous fluids administered during the initial phases of treatment.

Correct Answer is B

Explanation

A. is expected to be decreased for three to five days.
In the initial stages following severe burn injury, there is often oliguria (low urine output), but this is typically followed by diuresis (increased urine output) after the first 24-48 hours, not a decrease over 3-5 days.

B. will be reduced in the first 24-48 hours and will then increase.
In the first 24-48 hours following a severe burn injury, the body may undergo a state of hypovolemia and oliguria. As fluid resuscitation begins, urine output typically increases.

C. output will be greatest in the first 24 hours after the burn injury.
Although urine output may increase with proper fluid resuscitation, it is not usually greatest in the first 24 hours; the increase typically happens after the initial resuscitation period.

D. will be elevated due to the amount of intravenous fluids administered during the initial phases of treatment.
While fluid resuscitation leads to an increase in urine output after the first 24-48 hours, it is not expected to be elevated right away. The kidneys may initially respond with oliguria.
