The nurse prepares to begin a systematic assessment of a client's heart sounds. Upon positioning the stethoscope as seen in the picture, which should the nurse do first?
Listen for abnormal sounds.
Identify S1 and S2 heart sounds.
Move the stethoscope to the apical site.
Change to the bell of the stethoscope.
The Correct Answer is B
A. Listen for abnormal sounds. Before identifying abnormal sounds, it's essential to first establish a baseline by identifying the normal heart sounds (S1 and S2).
B. Identify S1 and S2 heart sounds. This is the correct first step in a systematic assessment of heart sounds. S1 ("lub") corresponds to the closure of the atrioventricular valves (mitral and tricuspid), while S2 ("dub") corresponds to the closure of the semilunar valves (aortic and pulmonic).
C. Move the stethoscope to the apical site. While the apical site is important for auscultating specific heart sounds, it's best to first identify S1 and S2 at the traditional auscultatory areas (aortic, pulmonic, tricuspid, and mitral).
D. Change to the bell of the stethoscope. The bell of the stethoscope is used to listen for lower-pitched sounds, but it's not typically used for identifying S1 and S2 heart sounds, which are higher-pitched.

Correct Answer is C
Explanation
A. Open-ended question. This response is not an open-ended question. Open-ended questions typically invite the client to share more information or elaborate on their thoughts and feelings. Instead, the nurse's response acknowledges the client's feelings and demonstrates empathy without directly soliciting more information.
B. Clarification. This response is not clarification. Clarification involves seeking clarification or additional information to ensure understanding. The nurse's response does not seek clarification but rather acknowledges the client's emotions.
C. Empathizing. This response is empathizing. Empathizing involves recognizing and understanding the client's emotions and expressing empathy. The nurse's response acknowledges the client's difficult situation and validates their feelings of distress, demonstrating empathy and understanding.
D. Paraphrasing. This response is not paraphrasing. Paraphrasing involves restating the client's message in the nurse's own words to confirm understanding. The nurse's response does not restate the client's message but rather expresses empathy and validation of the client's emotions.
Correct Answer is D
Explanation
A. Sensory dysfunction. Sensory dysfunction refers to impairment or abnormalities in the sensory system, such as touch, proprioception, or temperature sensation. Tremors, particularly those affecting movement, are not typically associated with sensory dysfunction.
B. Transient ischemic attack. Transient ischemic attack (TIA) is a temporary interruption of blood flow to the brain, resulting in transient neurological symptoms. Tremors are not a characteristic symptom of TIA, although other neurological deficits such as weakness, numbness, or speech disturbances may occur.
C. Muscle flaccidity. Muscle flaccidity refers to a state of reduced muscle tone or weakness, often associated with conditions such as stroke or spinal cord injury. Tremors are not typically described as muscle flaccidity; instead, they often involve rhythmic, involuntary movements of the muscles.
D. Intention tremor. This is the most appropriate option. An intention tremor is a type of tremor that occurs during purposeful movement, such as reaching for an object. It is often characterized by tremors that worsen as the individual approaches the target (e.g., reaching for a glass of water). Intention tremors can be associated with various neurological conditions, including essential tremor or cerebellar dysfunction.
