nclex physical and health assessment questions

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: 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: increased intracranial pressure. Papilledema is swelling of the optic disc due to increased pressure in the brain. It is a sign of serious conditions like brain tumors, head trauma, or hydrocephalus. The other choices are incorrect because retinal detachment presents with visual disturbances and floaters (A), diabetic retinopathy with retinal damage due to diabetes (B), and acute-angle glaucoma with sudden eye pain and blurred vision (C). Papilledema specifically indicates increased intracranial pressure, making choice D the correct answer.

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.
