The nurse is assessing the cranial nerves. Match the cranial nerve with its related function.

Motor innervation to the muscles of the jaw

Lateral movement of the eyeballs

Sensation of the pharynx

Downward, inward eye movements

Position of the tongue

Answer and Explanation

The Correct Answer is {"A":{"answers":"B"},"B":{"answers":"C"},"C":{"answers":"E"},"D":{"answers":"D"},"E":{"answers":"A"}}

The cranial nerves (CN I–XII) emerge directly from the brain and brainstem and control various motor, sensory, and parasympathetic functions of the head, neck, and some thoracic organs. During a comprehensive neurological assessment, the nurse must test these nerves to identify signs of neurologic dysfunction.

Rationale for correct answers:

1.XII Hypoglossal -e. Position of the tongue

The hypoglossal nerve controls the motor movement of the tongue. During assessment, the client is asked to stick out the tongue, and deviation or weakness indicates impairment of CN XII.

2. V Trigeminal -a. Motor innervation to the jaw

The trigeminal nerve has both motor and sensory components. Motor function includes muscles of mastication (chewing). The nurse assesses jaw movement and strength.

3. VI Abducens -b. Lateral movement of the eyeballs

The abducens nerve controls the lateral rectus muscle, which moves the eye laterally (abduction). Inability to look outward may suggest CN VI palsy.

4. IV Trochlear -d. Downward, inward eye movements

The trochlear nerve controls the superior oblique muscle, responsible for downward and inward eye movement. Difficulty with this motion may lead to vertical diplopia (double vision).

5. X Vagus -c. Sensation of the pharynx

The vagus nerve provides sensory innervation to the pharynx and larynx, and also has motor and parasympathetic functions. It plays a role in swallowing, speech, and the gag reflex.

Take home points

Each cranial nerve has specific motor, sensory, or both functions, and testing them individually helps identify the location and extent of neurological impairment.

Cranial nerves IV (Trochlear), VI (Abducens), and III (Oculomotor) are especially important for eye movement coordination.
CN V (Trigeminal) and XII (Hypoglossal) focus on facial sensation/mastication and tongue movement, respectively.

Correct Answer is ["A","C","D"]

Explanation

Pain is a subjective experience, but nurses can often detect pain through careful observation of a patient’s general appearance and behavior. Nonverbal cues such as posture, facial expressions, guarding behaviors, respiratory patterns, and general responsiveness are important indicators.

Rationale for correct answers:

1. Is slumped in the bed: A slumped posture can indicate discomfort or fatigue related to pain. Patients in pain often avoid repositioning themselves due to the fear of aggravating pain.

3. Is short of breath and breathing rapidly: Pain can activate the sympathetic nervous system, leading to increased respiratory rate and shallow breathing. This is especially common with acute or severe pain.

4. Protects and splints the left arm: Guarding or splinting a body part is a classic nonverbal sign of pain. It reflects an attempt to minimize movement and protect the area from further discomfort.

Rationale for incorrect answers:

2. Responds to questions by making eye contact: Making eye contact and appropriately responding to questions suggest the patient is engaged and cooperative.

5. Is alert and oriented: Being alert and oriented indicates intact cognition and neurological function. While pain does not rule out alertness, this finding is not directly associated with signs of discomfort or distress.

Take home points:

Nonverbal cues such as guarding, altered posture, and increased respiratory rate can signal that a patient is experiencing pain, especially if the patient is unable to verbalize it.
Objective observation during general assessment plays a key role in identifying pain and initiating timely interventions to promote comfort and prevent complications.

A. Place the fingers behind and below the medial malleolus. B. Have the patient slightly flex the knee with the foot resting on the bed. C. Have the patient relax the foot while lying supine. D. Palpate the groove lateral to the flexor tendon of the wrist.

Correct Answer is ["B","C"]

Explanation

After a femoral artery bypass, careful monitoring of distal perfusion is critical to detect signs of occlusion or ischemia early. One of the most important parameters is the assessment of distal pulses, such as the dorsalis pedis pulse, which provides information about blood flow to the lower extremities.

Rationale for correct answers:

2. Have the patient slightly flex the knee with the foot resting on the bed: Slightly flexing the knee and allowing the foot to rest on the bed relaxes the muscles of the lower leg and foot, making it easier to palpate the dorsalis pedis pulse on the dorsum (top) of the foot.

3. Have the patient relax the foot while lying supine: The dorsalis pedis pulse is best palpated when the client is in a supine position with the foot relaxed. This ensures muscles are not contracted, which could make the pulse more difficult to detect.

Rationale for incorrect answers:

1. Place the fingers behind and below the medial malleolus: This technique is used to palpate the posterior tibial pulse, not the dorsalis pedis pulse. The posterior tibial artery runs behind the medial malleolus (inner ankle), while the dorsalis pedis artery is located on the top of the foot.

4. Palpate the groove lateral to the flexor tendon of the wrist: This describes the technique for assessing the radial pulse, which is located on the wrist. It is unrelated to the dorsalis pedis pulse or assessing lower extremity circulation.

Take home points:

The dorsalis pedis pulse is located on the top of the foot, lateral to the extensor hallucis longus tendon.
It is best assessed with the patient lying supine and the foot relaxed.
Post-femoral artery bypass, monitoring distal pulses like the dorsalis pedis is essential to ensure graft patency and detect early signs of limb ischemia.
