nclex physical and health assessment questions

Correct Answer: A

Rationale: The correct answer is A: The presence of tears along the inner canthus. This is a normal finding during an eye examination as tears are produced by the lacrimal gland and drain into the nasolacrimal duct, which exits at the inner canthus. This indicates proper tear production and drainage. Incorrect choices: B: A blocked nasolacrimal duct in a newborn infant - This would present as excessive tearing and discharge. C: A slight swelling over the upper lid and along the bony orbit if the patient has a cold - This could indicate inflammation due to infection. D: The absence of drainage from the puncta when the inner orbital rim is pressed - This would suggest an issue with the lacrimal drainage system.

Correct Answer: C

Rationale: Rationale: 1. The middle ear conducts sound vibrations from the outer ear to the inner ear via the ossicles. 2. This transmission is essential for the inner ear to convert the vibrations into electrical signals for the brain to interpret as sound. 3. Maintaining balance (A) is the function of the inner ear's vestibular system. 4. Interpreting sounds (B) is done by the brain, not the middle ear. 5. Increasing amplitude (D) would distort sound perception, not enable inner ear function.

Correct Answer: B

Rationale: The correct answer is B (XI; asking the patient to shrug her shoulders against resistance). This is the correct choice because the nurse suspects damage to the spinal accessory nerve (CN XI), which innervates the trapezius and sternocleidomastoid muscles. Asking the patient to shrug her shoulders against resistance tests the function of the trapezius muscle, which is innervated by CN XI. This examination helps to assess the integrity of the nerve and its ability to innervate the muscle. Palpating the anterior and posterior triangles (choice A) is not specific to CN XI function. Percussing the sternomastoid and submandibular neck muscles (choice C) is related to CN XII, not CN XI. Assessing for a positive Romberg's sign (choice D) is not relevant to testing the function of CN XI.

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: 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.
