Listen to the client’s speech

Ask the client to identify scented aromas

Ask the client to clench his teeth

Ask the client to read a Snellen chart

Answer and Explanation

The Correct Answer is D

Choice A rationale: Listening to the client's speech is not related to the assessment of cranial nerve II.

Choice B rationale: Assessing the ability to identify scented aromas is more related to cranial nerve I (olfactory nerve).

Choice C rationale: Asking the client to clench their teeth is related to the assessment of cranial nerve V (trigeminal nerve).

Choice D rationale: Cranial nerve II, the optic nerve, is responsible for vision. The nurse should use the Snellen chart to assess visual acuity.

Correct Answer is B

Explanation

Choice A rationale: Measuring the circumference of the ankle is not a specific method for screening DVT.

Choice B rationale: To screen for deep vein thrombosis (DVT), measuring the calf at the widest point with a tape measure is appropriate. A significant increase in calf circumference may indicate swelling due to DVT.

Choice C rationale: Checking the dorsalis pedis pulse is not a direct method for screening DVT. Pulses are assessed for arterial circulation.

Choice D rationale: Compressing the dorsalis pedis pulse is not a standard method for screening DVT. DVT assessment involves evaluating for swelling, pain, and changes in skin temperature.

A. The central nervous system consists of the brain and electrical impulse stimulators B. The central nervous system is made up of the hypothalamus and cerebral nerves C. The central nervous system is made up of the brain and spinal cord D. The central nervous system includes the peripheral and autonomic components

Correct Answer is C

Explanation

Choice A rationale: The central nervous system consists of the brain and spinal cord, not "electrical impulse stimulators."

Choice B rationale: The hypothalamus is a part of the brain, but the central nervous system encompasses both the brain and the spinal cord.

Choice C rationale: The central nervous system (CNS) is made up of the brain and spinal cord. The CNS processes and interprets sensory information and sends motor commands to effectors.

Choice D rationale: The peripheral nervous system and autonomic nervous system are distinct from the central nervous system and are not part of the CNS.
