A nurse assisting with data collection is testing the cochlear portion of the acoustic nerve (cranial nerve VIII). Which action does the nurse take to test this nerve?

Correct Answer: D

Rationale: To test the cochlear portion of the acoustic nerve (cranial nerve VIII), the nurse should have the client close their eyes and indicate when a ticking watch is heard as the nurse moves the watch closer to the client's ear. This action assesses the client's ability to perceive auditory stimuli, as the cochlear portion of the acoustic nerve is responsible for hearing. Choices A, B, and C are incorrect. Asking the client to raise their eyebrows to check for symmetry is a method to test the facial nerve (cranial nerve VII). Asking the client to clench their teeth and palpating the masseter muscles tests the motor component of the trigeminal nerve. Having the client identify light and sharp touch on both sides of the face is a way to test the sensory component of the trigeminal nerve (cranial nerve V).

Correct Answer: B

Rationale: The Tinel sign is elicited by percussing at the location of the median nerve at the wrist. In carpal tunnel syndrome, this test can produce burning and tingling along the nerve's distribution. Choices A, C, and D are incorrect. Testing for the strength of each muscle joint and checking for repetitive movements in the joints involve different assessments unrelated to the Tinel sign. Asking the client to flex the wrist 90 degrees while holding the hands back to back is associated with the Phalen test, which is another evaluation for carpal tunnel syndrome.

Correct Answer: A

Rationale: To auscultate for bowel sounds, the nurse should use the diaphragm end piece of the stethoscope as bowel sounds are relatively high pitched. The stethoscope should be held lightly against the skin to avoid stimulating more bowel sounds. The nurse should begin in the right lower quadrant at the ileocecal valve, where bowel sounds are normally present. It is recommended to listen for 5 minutes before deciding that bowel sounds are absent to ensure a thorough assessment. Choice B is incorrect because the bell end is used for low-pitched sounds such as heart sounds. Choice C is incorrect as holding the stethoscope firmly and deeply can cause unnecessary bowel sound stimulation. Choice D is incorrect as listening for 1 minute is insufficient to determine the presence or absence of bowel sounds.

Correct Answer: B

Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.

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.
