Correct Answer: D

Rationale: The correct answer is D: Peripheral vision. The confrontation test is a gross measure of peripheral vision. It compares the client's peripheral vision with the nurse's, assuming that the nurse's vision is normal. During the test, the nurse positions themselves at eye level with the client, about 2 feet away, and directs the client to cover one eye with an opaque card. The nurse covers the eye opposite the client's covered one and slowly moves a target (like a pencil) from the periphery in several directions. The client is asked to indicate when they see the target, which should coincide with when the nurse sees it. Near vision is tested using a handheld vision screener with various sizes of print, color vision with the Ishihara test, and distant vision with a Snellen chart. Therefore, choices A, B, and C are incorrect as they do not measure peripheral vision, which is the focus of the confrontation test.

Correct Answer: D

Rationale: The ability of a preschooler to move five blocks to a piece of paper and state there are five blocks on the paper is evidence that the preschooler has the ability of conservation. This concept refers to the fact that the quantity of something doesn't change just because the shape, contour, and so on has changed. Five blocks are still five blocks, whether they are lying beside the paper, stacked on the paper, or moved to the paper. Centration is the ability to concentrate on one feature of a situation while neglecting all other aspects. Causality is based on the sequence of events, one event ordinarily following another. Non-reversibility refers to the inability of preschoolers to reverse their operations. They are only able to think forward, not retrace or reverse their thought processes.

Correct Answer: D

Rationale: To test the cochlear portion of the acoustic nerve (cranial nerve VIII), the nurse should have the client close their eyes and indicate when a ticking watch is heard as the nurse moves the watch closer to the client's ear. This action assesses the client's ability to perceive auditory stimuli, as the cochlear portion of the acoustic nerve is responsible for hearing. Choices A, B, and C are incorrect. Asking the client to raise their eyebrows to check for symmetry is a method to test the facial nerve (cranial nerve VII). Asking the client to clench their teeth and palpating the masseter muscles tests the motor component of the trigeminal nerve. Having the client identify light and sharp touch on both sides of the face is a way to test the sensory component of the trigeminal nerve (cranial nerve V).

Correct Answer: A

Rationale: The correct interpretation of the Chadwick sign is that the cervix appears violet in color. This sign is a probable sign of pregnancy, characterized by the violet coloration of the cervix due to increased vascularity of the pelvic organs. It is not a definitive positive sign of pregnancy but rather a probable one. Choices B and D are incorrect as cervical softening is known as the Goodell sign, and thinning of the cervix is referred to as the Hegar sign. These signs are also probable signs of pregnancy, but they do not specifically indicate the Chadwick sign.

Correct Answer: A

Rationale: To auscultate for bowel sounds, the nurse should use the diaphragm end piece of the stethoscope as bowel sounds are relatively high pitched. The stethoscope should be held lightly against the skin to avoid stimulating more bowel sounds. The nurse should begin in the right lower quadrant at the ileocecal valve, where bowel sounds are normally present. It is recommended to listen for 5 minutes before deciding that bowel sounds are absent to ensure a thorough assessment. Choice B is incorrect because the bell end is used for low-pitched sounds such as heart sounds. Choice C is incorrect as holding the stethoscope firmly and deeply can cause unnecessary bowel sound stimulation. Choice D is incorrect as listening for 1 minute is insufficient to determine the presence or absence of bowel sounds.
