A client was recently diagnosed with a heart murmur and is asking the nurse for more information. The nurse will educate the client that a heart murmur:
indicates turbulent blood flow through a valve.
is an extra sound due to blood entering an inflexible chamber.
means that there is some inflammation around the heart.
is a high-pitched sound due to a narrow valve.
The Correct Answer is A
A. Indicates turbulent blood flow through a valve:
This statement is correct. A heart murmur is an abnormal sound during the heartbeat cycle, often indicating turbulent blood flow through a valve. Murmurs can result from various factors such as valve disorders, structural abnormalities, or other heart conditions.
B. Is an extra sound due to blood entering an inflexible chamber:
This statement is not accurate. Heart murmurs are primarily associated with turbulent blood flow rather than an extra sound related to an inflexible chamber.
C. Means that there is some inflammation around the heart:
This statement is incorrect. Heart murmurs are not specifically related to inflammation around the heart. They are primarily caused by issues with blood flow through the heart valves.
D. Is a high-pitched sound due to a narrow valve:
This statement is a bit oversimplified. While murmurs can sometimes be associated with narrow valves (stenosis), they can also result from various other valve abnormalities or conditions, and not all murmurs are high-pitched. The pitch and characteristics of a murmur can provide clues about its cause, but they are not the sole indicators.

Correct Answer is C
Explanation
A. VI
Cranial Nerve VI is the Abducent Nerve, which controls the movement of the lateral rectus muscle, allowing the eye to move laterally (abduct). Dysfunction of this nerve can cause difficulty in moving the eye outward.
B. V
Cranial Nerve V is the Trigeminal Nerve. It has both sensory and motor functions. Sensory functions include providing sensation to the face, sinuses, and teeth. Motor functions include controlling the muscles used for chewing (mastication).
C. II
Cranial Nerve II is the Optic Nerve. It is purely a sensory nerve responsible for vision. The optic nerve carries visual information from the retina of the eye to the brain.
D. III
Cranial Nerve III is the Oculomotor Nerve. It is primarily a motor nerve but also has some autonomic functions. It controls most of the eye movements (except lateral movement controlled by VI) and regulates the size of the pupil and the shape of the lens in the eye for focusing.
Correct Answer is D
Explanation
A. Perform the confrontation test:
The confrontation test is a basic visual field screening test. It assesses the peripheral vision by having the patient cover one eye and the examiner covers the opposite eye. The patient and the examiner then bring their fingers into the visual field from the periphery, and the patient indicates when they see the fingers.
B. Ask the patient to read the print on a handheld Jaeger card:
Jaeger cards are used for near vision testing. The patient reads progressively smaller print to assess their near vision acuity.
C. Determine the patient's ability to read newsprint at a distance of 12 to 14 inches:
This method assesses near vision. It is often used informally in clinical settings, where the patient is asked to read a newspaper or similar print at a comfortable reading distance.
D. Use the Snellen chart positioned 20 feet away from the patient:
The Snellen chart is a standardized chart used for visual acuity testing. It is placed 20 feet away from the patient, and the patient is asked to read the letters or symbols on the chart with one eye covered at a time.
