nclex physical and health assessment questions

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: 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. The "soft spot" on a baby's head, also known as the fontanelle, is a normal anatomical feature that allows for the growth and development of the baby's brain during the first year of life. It is a gap between the bones of the skull that eventually closes as the baby grows. Response A is incorrect because the fontanelle is not related to maternal dietary intake during pregnancy. Response B is incorrect as craniosynostosis is a condition where the sutures of the skull close prematurely, leading to abnormal head shape. Response C is incorrect as cretinism and congenital hypothyroidism are not typically associated with the fontanelle. Overall, the correct response, D, provides an accurate explanation of the normal function of the fontanelle in a newborn's development.

Correct Answer: D

Rationale: The correct answer is D: mandible. The temporomandibular joint is located just below the temporal artery and it connects the mandible (lower jaw) to the temporal bone. This joint allows for movement of the jaw during actions like chewing and speaking. Choices A, B, and C are incorrect because the temporomandibular joint is not located near the hyoid bone (A), the vagus nerve (B), or the tragus of the ear (C). These structures are not directly associated with the temporomandibular joint's anatomical location and function.

Correct Answer: C

Rationale: The correct answer is C: In an individual who is severely dehydrated. Decreased skin turgor is a clinical sign of dehydration, indicating loss of skin elasticity due to fluid loss. Severe dehydration leads to decreased skin turgor as the skin loses its ability to recoil when pinched. In cases of severe obesity (choice A), skin turgor is usually normal or increased due to excess adipose tissue. During childhood growth spurts (choice B), skin turgor is typically unaffected. Connective tissue disorders like scleroderma (choice D) can lead to changes in skin texture and appearance, but not necessarily decreased skin turgor.
