nclex physical and health assessment questions

Correct Answer: D

Rationale: The correct answer is D because intraocular pressure is primarily determined by the amount of aqueous humor produced and the resistance to its outflow at the angle of the anterior chamber. When there is an imbalance in the production and outflow of aqueous humor, it can lead to an increase in intraocular pressure, which can result in conditions like glaucoma. Choices A, B, and C are incorrect because they do not directly influence intraocular pressure. The thickness or bulging of the lens (A) is related to accommodation for near vision, the posterior chamber accommodating fluid (B) is not a primary factor in determining intraocular pressure, and the contraction of the ciliary body (C) affects the shape of the lens for focusing rather than intraocular pressure regulation.

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: 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: A

Rationale: The correct answer is A: No sensation. When the sinus areas are normal, the patient should not feel any discomfort or pain upon palpation. This indicates that there is no inflammation or infection present. Choices B, C, and D are incorrect because feeling firm pressure, experiencing pain during palpation, or feeling pain behind the eyes would suggest abnormalities in the sinuses, such as congestion, inflammation, or infection. Therefore, the absence of any sensation is the expected response when the sinuses are normal.

Correct Answer: C

Rationale: The correct answer is C: myxedema. This is a classic presentation of hypothyroidism, specifically myxedema, characterized by puffy eyes, coarse hair, and dry skin. The thyroid hormone deficiency leads to decreased metabolic activity, causing these symptoms. Cachexia (A) is severe muscle wasting seen in conditions like cancer. Cretinism (B) is congenital hypothyroidism leading to mental retardation. Scleroderma (D) is a connective tissue disorder causing skin thickening, not typically associated with these symptoms.
