health assessment practice questions nursing

Correct Answer: C

Rationale: The correct answer is C: turbinates. Turbinates are bony projections in the nasal cavity that increase the surface area for the warming, humidifying, and filtering of inhaled air. Meatus (A) refers to the passages in the nasal cavity, not the projections. Septum (B) is the partition between the nostrils, not the projections. Kiesselbach's plexus (D) is a collection of blood vessels in the nasal septum, not the projections that increase surface area.

Correct Answer: B

Rationale: The correct answer is B. When using an otoscope to assess the nasal cavity, it is crucial to avoid touching the nasal septum with the speculum to prevent discomfort or injury to the patient. Touching the nasal septum can cause pain and potential damage. Incorrect Choices: A: Inserting the speculum at least 3 cm into the vestibule is not necessary and may cause discomfort or injury to the patient. C: Displacing the nose to the side being examined is not required and may not provide any additional benefit during the assessment. D: Keeping the speculum tip medial to avoid touching the floor of the nares is not as critical as avoiding contact with the nasal septum, which is more sensitive and can be easily injured.

Correct Answer: B

Rationale: The correct answer is B: pearly grey and slightly concave. This is because a healthy tympanic membrane should appear pearly grey in color and slightly concave in shape. The pearly grey color indicates normal transparency and reflection of light, while the slightly concave shape is indicative of a normal eardrum. Choice A is incorrect as a light pink color and slight bulge are not characteristic of a healthy tympanic membrane. Choice C is incorrect because a pulled-in appearance at the base of the cone of light suggests retraction, which is abnormal. Choice D is incorrect as a whitish color with a small fleck of light is not a typical presentation of a healthy tympanic membrane.

Correct Answer: D

Rationale: The correct answer is D: convergence of the axes of the eyes. During the accommodation response, the eyes converge to focus on a near object. This is necessary to maintain clear vision when looking at close objects. Dilation of the pupils (A) is not part of the accommodation response. A consensual light reflex (B) refers to both pupils constricting simultaneously in response to light, not specific to accommodation. Conjugate movement of the eyes (C) refers to both eyes moving together in the same direction, which is not the primary action during accommodation.

Correct Answer: C

Rationale: The correct answer is C: turbinates. Turbinates are bony projections in the nasal cavity that increase the surface area for the warming, humidifying, and filtering of inhaled air. Meatus (A) refers to the passages in the nasal cavity, not the projections. Septum (B) is the partition between the nostrils, not the projections.
