A nurse is auscultating heart sounds on a client and hears an extra sound late in diastole, just before the S1. How should the nurse document this finding?
The third heart sound (S3)
The fourth heart sound (S4)
A split-second heart sound S2
A friction nub
The Correct Answer is B
A) The third heart sound (S3): The third heart sound (S3) occurs early in diastole, immediately following S2. It is often associated with conditions that cause increased volume and pressure in the ventricles, such as heart failure or dilated cardiomyopathy. S3 is not heard late in diastole, so it does not match the described timing of the extra heart sound.
B) The fourth heart sound (S4): The fourth heart sound (S4) is heard late in diastole, just before S1. It is caused by the atria contracting forcefully to push blood into a non-compliant or stiff ventricle, often associated with conditions like left ventricular hypertrophy or ischemic heart disease. The timing of S4, occurring just before S1, makes it the correct identification of the described extra heart sound.
C) A split second heart sound S2: A split S2 occurs when the aortic and pulmonic valves do not close simultaneously, causing the second heart sound (S2) to be heard as two distinct components. This split can vary with respiration but does not occur late in diastole. Therefore, it does not align with the extra heart sound heard just before S1.
D) A friction rub: A friction rub is a sound associated with pericarditis, caused by the rubbing of inflamed pericardial layers. It has a distinct, grating quality and can be heard throughout the cardiac cycle. A friction rub is not a late diastolic sound, making it an incorrect identification for the extra heart sound described.

Correct Answer is A
Explanation
A) Whisper random numbers and letters, then have the client repeat them:
This is correct. The voice test is a simple way to assess a client's hearing. The nurse should stand about 2 feet away from the client and whisper random numbers or letters. The client should repeat what they hear. This test checks the ability to hear and distinguish sounds, particularly for high-frequency tones. It's an effective screening method for detecting hearing loss.
B) Shield the lips so that the sound is muffled:
This is incorrect. The nurse should not shield their lips during the voice test because it could interfere with the client's ability to hear and potentially read the nurse's lips, which can help with understanding. The client should be allowed to observe lip movements to aid in comprehension of the sounds being spoken.
C) Stand approximately 4 feet away from the client:
This is incorrect. The recommended distance for performing the voice test is typically around 2 feet, not 4 feet. Standing too far away can make it more difficult for the client to hear the whispered numbers or letters and could affect the accuracy of the test. The nurse should stand close enough (about 2 feet) to ensure that the sound is audible to the client but not too close as to distort the test.
D) Have the client place a finger in the ear canal to occlude outside noise:
This is incorrect. While the client should be instructed to avoid distractions or loud environments during the test, placing a finger in the ear canal is not necessary. The test assesses the client's ability to hear sound, and occluding the ear could affect the results. The client should simply be in a quiet environment.
Correct Answer is ["B","C","E"]
Explanation
A) Client's oral temperature is 38.4°C (101.2°F):
This is objective data, as it is a measurable, observable finding obtained through direct assessment (in this case, using a thermometer). Objective data are facts or measurements that can be verified or observed by the healthcare provider.
B) Client reports the rash on their back is itchy:
This is subjective data, as it is based on the client's personal experience and report. The feeling of itchiness cannot be directly measured or observed by the nurse; it is something the client experiences and describes. Subjective data include symptoms, sensations, or feelings reported by the client.
C) Client reports nausea following administration of pain medication:
This is subjective data. Nausea is a symptom that the client reports experiencing, which cannot be objectively measured or directly observed by the nurse. It is based on the client's perception and report, making it subjective.
D) Client has a vesicular rash on their upper back:
This is objective data. The rash is something the nurse can observe and describe. Objective data include observable facts, such as physical exam findings, lab results, or diagnostic test results.
E) Client reports dull, aching pain in lower right calf:
This is subjective data, as pain is a sensation that the client experiences and describes. The intensity, location, and type of pain (dull, aching) are subjective experiences that only the client can report.
