nclex physical and health assessment questions

Correct Answer: A

Rationale: The correct answer is A: auricle. The auricle is the visible, outer portion of the ear made up of movable cartilage and skin. It serves to collect sound waves and direct them into the ear canal. The other choices are incorrect because the concha (B) is the concave cavity leading to the ear canal, the outer meatus (C) is the ear canal itself, and the mastoid process (D) is a bony protrusion behind the ear that has no role in sound collection.

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: C

Rationale: The correct answer is C because the nurse should use the Snellen chart positioned 6.1 m (20 ft) away to assess visual acuity. This is the standard method for testing distance vision. The nurse should ask the patient to read the letters on the chart from the top row down, covering one eye at a time if necessary. This method provides an accurate measurement of visual acuity at a distance. A: Performing the confrontation test assesses visual fields, not visual acuity. B: Using a Jaeger card is for near vision testing, not distance visual acuity. D: Assessing the ability to read newsprint at a close distance does not provide an accurate measurement of visual acuity at a distance.

Correct Answer: D

Rationale: The correct answer is D because cranial nerve X, also known as the vagus nerve, controls the movement of the soft palate and uvula. Asking the patient to say "ahhh" assesses the function of CN X as the soft palate and uvula should elevate symmetrically. A: Observing the patient's ability to articulate specific words does not specifically test CN X function. B: Assessing movement of the hard palate and uvula with the gag reflex primarily tests CN IX (glossopharyngeal nerve). C: Having the patient stick out the tongue and observing for tremors or pulling to one side primarily tests CN XII (hypoglossal nerve).

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.
