nclex physical and health assessment questions

Correct Answer: D

Rationale: The correct answer is D: the bony labyrinth. The bony labyrinth is the portion of the inner ear that includes the vestibular system responsible for balance and spatial orientation. This system detects rotational movements and contributes to the sensation of vertigo or spinning. Choice A, the cochlea, is responsible for hearing. Choice B, CN VIII (vestibulocochlear nerve), transmits auditory and balance-related information but is not the physical structure responsible for the sensation of spinning. Choice C, the organ of Corti, is located within the cochlea and is responsible for auditory transduction, not balance sensations.

Correct Answer: D

Rationale: The correct answer is D. At 18 months, it is expected for a child to have erupted around 16 deciduous teeth. The rationale for this answer is based on dental development milestones. By age 3, most children should have their full set of 20 primary teeth. Therefore, the nurse should inform the mother that it is normal for an 18-month-old to have around 16 teeth. Choice A is incorrect as comparing the mother's teeth at that age is irrelevant to the child's dental development. Choice B is incorrect because all 20 deciduous teeth should be present by age 3, not 4. Choice C is incorrect as having 12 teeth at 18 months is below the expected number of erupted teeth for that age.

Correct Answer: A

Rationale: The correct answer is A: An optic disc that is a yellow-orange colour. This is a normal finding because the optic disc typically appears yellow-orange due to the presence of nerve fibers. The yellow-orange color is due to the absence of blood vessels in this area. This is a normal anatomical characteristic of the optic disc. Option B is incorrect because blurred optic disc margins can indicate pathology such as papilledema. Option C is incorrect because the presence of pigmented crescents in the macular area can indicate a condition like myopic degeneration, not a normal finding. Option D is incorrect because the macula is normally located temporally, not nasally, to the optic disc.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Whispering two-syllable words ensures a low volume, requiring the patient to focus on clarity. 2. Asking the patient to repeat tests their ability to hear and understand the whispered words accurately. 3. Whispering helps eliminate the influence of lip-reading, ensuring accurate assessment. Summary: A: Shielding the lips while speaking would hinder the patient's ability to hear clearly. C: Placing a finger in the ear would not be appropriate as it could affect the accuracy of the test. D: Standing at a specific distance does not ensure accurate assessment of hearing ability.

Correct Answer: B

Rationale: The correct answer is B: cluster headaches. Cluster headaches are characterized by excruciating pain on one side of the head, often around the eye, forehead, and cheek. They occur once or twice each day and last for a relatively short duration of 30 minutes to 2 hours. This pattern of symptoms aligns with the typical presentation of cluster headaches. Incorrect Choices: A: Hypertension is unlikely to present with such specific unilateral head pain patterns and timing. C: Tension headaches typically present with more diffuse, mild to moderate pain and are not typically associated with eye, forehead, or cheek pain. D: Migraine headaches usually last longer than 2 hours and are commonly associated with other symptoms such as nausea, vomiting, and sensitivity to light and sound.
