nclex practice questions 2023 health assessment

Correct Answer: C

Rationale: The correct answer is C because lymph nodes are accessible for examination in the head and neck, arms, breasts, and axillae. Lymph nodes are present in these areas where they can be easily palpated and assessed for any signs of inflammation or abnormalities. The other choices are incorrect because they do not include all the areas where lymph nodes are accessible for examination. Choice A does not include the axillae, which is a crucial area for examining lymph nodes in the arms. Choice B does not include the axillae and breasts. Choice D does not include the breasts, which are important areas for lymph node examination in cases of breast cancer or other breast-related conditions.

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.

Correct Answer: C

Rationale: Step 1: Dark skin may not show cyanosis well, making choice A less reliable. Step 2: Erythema refers to redness, which may not be easily visible in dark skin, making choice B less suitable. Step 3: Palpating for edema and increased warmth allows for a more reliable assessment of inflammation in dark skin, making choice C the correct answer. Step 4: Palpating for tenderness and ecchymosis may be useful but not specific to inflammation assessment in dark skin, making choice D less relevant.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C (CN VII) is correct: 1. Palpebral fissures are controlled by muscles innervated by CN VII (facial nerve). 2. Damage to CN VII can result in facial asymmetry, affecting palpebral fissures. 3. CN III (choice A) controls eye movement, not palpebral fissures. 4. CN V (choice B) controls facial sensation, not palpebral fissures. 5. CN VIII (choice D) controls hearing and balance, not palpebral fissures. Summary: Choice C is correct as damage to CN VII affects palpebral fissures due to facial muscle innervation. Choices A, B, and D are incorrect as they do not control the muscles responsible for palpebral fissures.

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.
