nclex practice questions 2023 health assessment Questions

Question 1 of 5

A patient in her first trimester of pregnancy is diagnosed with rubella. Which of the following indicates the significance of this in relation to the infant's hearing?

Correct Answer: B

Rationale: The correct answer is B because rubella can indeed damage the organ of Corti in the fetus, which is responsible for hearing. During the first trimester, when the hearing structures are forming, any damage to the organ of Corti can result in impaired hearing for the infant. Choice A is incorrect because rubella can impact the fetus, including the organs responsible for hearing. Choice C is incorrect because rubella can be harmful to the fetus at any stage of pregnancy, not just the second trimester. Choice D is incorrect because CN VIII (the vestibulocochlear nerve) is not directly affected by rubella, rather it is the organ of Corti that is damaged.

Question 2 of 5

The nurse suspects that a patient has otitis media. Which of the following findings of the tympanic membrane are early signs of otitis media?

Correct Answer: A

Rationale: The correct answer is A: Red and bulging. In otitis media, the tympanic membrane becomes red and bulging due to inflammation and fluid accumulation. This is an early sign as it indicates increased pressure within the middle ear. Choice B (Hypomobility) is incorrect because it refers to decreased movement of the tympanic membrane, which is not specific to otitis media. Choice C (Retraction with landmarks clearly visible) is incorrect as it suggests the tympanic membrane is pulled inward, which is more indicative of otitis media with effusion rather than acute otitis media. Choice D (Flat, slightly pulled in at the center, and moves with insufflation) is incorrect as it describes a normal or retracted tympanic membrane rather than the characteristic red and bulging appearance seen in otitis media.

Question 3 of 5

Which of the following cranial nerves (CNs) is responsible for conducting nerve impulses to the brain from the organ of Corti?

Correct Answer: C

Rationale: The correct answer is C: CN VIII. The vestibulocochlear nerve (CN VIII) is responsible for conducting nerve impulses from the organ of Corti in the inner ear to the brain. This nerve specifically carries auditory information to the brainstem and auditory cortex for processing. Choice A (CN I) is incorrect as it is the olfactory nerve responsible for smell. Choice B (CN III) is incorrect as it is the oculomotor nerve responsible for eye movement. Choice D (CN XI) is incorrect as it is the accessory nerve responsible for neck and shoulder movements.

Question 4 of 5

The primary purpose of the ciliated mucous membrane in the nose is to:

Correct Answer: B

Rationale: The correct answer is B: filter out dust and bacteria. The ciliated mucous membrane in the nose traps dust and bacteria present in the inhaled air through the mucus layer and then moves them towards the throat to be swallowed or expelled. This helps in protecting the respiratory system from harmful particles. Choice A is incorrect as the warming of inhaled air is primarily done by the nasal passages and sinuses, not the ciliated mucous membrane. Choice C is incorrect because the filtering of coarse particles is also done by the nasal hairs and the mucous membrane working together, not just the ciliated mucous membrane alone. Choice D is incorrect as the movement of air through the nares is mainly controlled by the size of the nostrils and is not the primary function of the ciliated mucous membrane.

Question 5 of 5

The salivary gland that is located in the cheek in front of the ear is the:

Correct Answer: A

Rationale: The correct answer is A: parotid gland. This gland is located in the cheek in front of the ear. It is the largest salivary gland in the human body. The parotid gland secretes saliva into the mouth through Stenson's duct. The other choices are incorrect because Stenson's gland does not exist, the sublingual gland is located under the tongue, and the submandibular gland is located under the mandible. Therefore, the parotid gland is the only gland that fits the description given in the question.
