The nurse is preparing to assess the motor function of the client's trigeminal nerve. Which of the following tests would be most appropriate for the nurse to use?
Have the client smile, frown, and puff out their cheeks
Palpate the masseter muscles when the client clenches their teeth
Assess constriction of the client's pupils with direct and indirect light
Ask the patient to turn their head left and right with resistance
The Correct Answer is B
A) Have the client smile, frown, and puff out their cheeks: This test assesses the facial nerve (cranial nerve VII), not the trigeminal nerve (cranial nerve V). While important for evaluating facial movement, it does not specifically test the motor function of the trigeminal nerve, which is responsible for mastication.
B) Palpate the masseter muscles when the client clenches their teeth: This is the correct test for assessing the motor function of the trigeminal nerve. The trigeminal nerve innervates the muscles responsible for chewing, and palpating the masseter muscles during clenching allows the nurse to evaluate muscle strength and function. It provides insight into the motor capabilities associated with this cranial nerve.
C) Assess constriction of the client's pupils with direct and indirect light: This test evaluates the function of the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III). It does not assess the trigeminal nerve and is not relevant for this assessment.
D) Ask the patient to turn their head left and right with resistance: This action tests the spinal accessory nerve (cranial nerve XI), which is involved in neck movement. It does not relate to the function of the trigeminal nerve, making it an inappropriate choice for this specific assessment.

Correct Answer is A
Explanation
A) Crepitus: This is the correct term to document the grating sound heard when a joint is moved. Crepitus can indicate issues such as the presence of air in the joint, cartilage degeneration, or other pathologies. Using this specific term provides clarity to the medical record and helps other healthcare providers understand the nature of the joint's condition.
B) Positive joint sounds: This phrase is less specific and does not adequately describe the type of sound noted during the assessment. It may also lead to ambiguity, as it lacks the medical precision that crepitus provides.
C) Grating and popping: While this description conveys what the nurse observed, it is not a standardized medical term. Precise documentation is essential in medical records, and using non-standard language can lead to confusion.
D) Crackles: Typically associated with respiratory assessments, crackles refer to sounds heard in the lungs and are not applicable to joint examinations. Therefore, this term would be inappropriate for documenting findings related to joint movement.
Correct Answer is D
Explanation
A) Changes in peripheral vision in response to light: While peripheral vision is important in a comprehensive eye assessment, it is not specifically evaluated through the PERRLA acronym. PERRLA focuses on how the pupils respond to light and accommodation, not on peripheral vision changes.
B) Involuntary blinking in the presence of bright light: Involuntary blinking is part of a reflex action known as the blink reflex, which helps protect the eyes from bright lights and foreign objects. However, this response is not what the "A" in PERRLA refers to, which is more specifically about pupillary reactions to focus.
C) Pupillary dilation when looking at a near object: When focusing on a near object, the pupils actually constrict rather than dilate. This process, known as accommodation, is important for clear vision at close distances but does not pertain to the dilation of pupils.
D) Pupillary constriction when looking at a near object: The "A" in PERRLA stands for accommodation, which specifically refers to the pupils constricting when a person looks at a nearby object. This reaction helps the eyes focus properly and is a normal finding in a healthy neurological assessment. Thus, option D accurately describes the "A" in the PERRLA assessment.
