The nurse assesses a client's submental lymph nodes. In which area of the client's head should the nurse palpate these lymph nodes?
In front of the ear.
In the midline, a few centimeters behind the tip of the mandible.
Superficial to the sternomastoid.
At the angle of the mandible.
The Correct Answer is B
Choice A reason:
Palpating in front of the ear would assess the preauricular lymph nodes, not the submental lymph nodes. The preauricular nodes are located just in front of the ears and are typically examined when there is an infection or inflammation in the eyes, ears, or scalp.
Choice B reason:
The submental lymph nodes are located in the midline, just under the chin, behind the bony prominence of the mandible. This is the correct area for palpation when assessing the submental lymph nodes. These nodes drain the lower lip, the floor of the mouth, the tip of the tongue, and the incisors, and they can become enlarged due to infections or malignancies in these areas.
Choice C reason:
Palpating superficial to the sternomastoid would assess the cervical lymph nodes, specifically the anterior cervical nodes, which are not the submental lymph nodes. The sternomastoid muscle is a landmark for several lymph node groups in the neck, but not for the submental group.
Choice D reason:
Palpating at the angle of the mandible would assess the submandibular lymph nodes, not the submental lymph nodes. The submandibular nodes are located beneath the jawline and can become enlarged due to infections or malignancies in the mouth, throat, and salivary glands.

Correct Answer is A
Explanation
Choice a reason:
The tympanic membrane, also known as the eardrum, is a critical component of the middle ear. It is a thin membrane that separates the external ear from the middle ear and vibrates in response to sound waves. These vibrations are then transmitted to the ossicles within the middle ear, which amplify and carry the sound to the inner ear.
Choice b reason:
The ear lobe is part of the external ear, not the middle ear. It is composed of soft skin and fatty tissue and does not play a role in hearing. The ear lobe serves primarily as a site for body decoration such as earrings.
Choice c reason:
The cochlea is a structure located in the inner ear. It is a spiral-shaped organ that contains the organ of Corti, the sensory organ of hearing. The cochlea converts the mechanical vibrations from the middle ear into nerve impulses that are sent to the brain.
Choice d reason:
The pinna, or auricle, is the visible part of the external ear. It is made of cartilage and skin and functions to capture sound waves and direct them into the ear canal towards the tympanic membrane.
Correct Answer is C
Explanation
Choice a reason:
A firm toothbrush is not recommended for plaque removal as it can damage the gums and tooth enamel. Soft-bristled toothbrushes are preferred because they are effective at removing plaque while being gentle on the gums and enamel.
Choice b reason:
Brushing more than twice per day does not necessarily irritate the gums unless done with improper technique or with a hard-bristled toothbrush. It is important to brush gently with a soft-bristled toothbrush and to use fluoride toothpaste to maintain oral hygiene and prevent gingivitis.
Choice c reason:
Ensuring that dental restorations such as fillings and crowns fit well is crucial in preventing gingivitis. Poorly fitted restorations can trap food particles and bacteria, leading to plaque buildup and gum inflammation. Regular dental check-ups can help ensure that restorations remain intact and do not contribute to gingivitis.
Choice d reason:
Flossing should not be avoided even if there is bleeding at the gumline. Bleeding can be a sign of gingivitis, and flossing can help remove the plaque and bacteria causing the inflammation. If bleeding persists, it is important to consult a dentist.
