The nurse auscultates the precordium of a client who is diagnosed with mitral valve regurgitation and hears a grade IV systolic murmur. When documenting the comparison of systolic murmurs, which characteristics should the nurse use to support this systolic finding?
Loud, at the apex, associated with a palpable thrill.
Very loud, with no stethoscope, thrill easily palpable, heave visible.
Soft, barely heard on auscultation in a quiet room.
Moderately loud, machine-like rumble, not associated with a thrill.
The Correct Answer is A
A. A grade IV systolic murmur is considered loud and may be associated with a palpable thrill. In mitral valve regurgitation, the murmur is often best heard at the apex of the heart. A thrill, which is a vibration felt on the chest wall, is a sign of a more significant murmur. This description is consistent with a grade IV murmur, which is typically loud and may indeed be associated with a thrill.
B. Very loud, with no stethoscope, thrill easily palpable, heave visible.
B. A grade V systolic murmur is very loud and can be heard with the stethoscope barely touching the chest. It often comes with a palpable thrill and may be accompanied by a visible heave or lift of the
chest wall. This description is consistent with a grade V murmur, not grade IV. Therefore, it’s not the
correct description for a grade IV murmur.
C. A soft murmur, barely audible, describes a grade I or grade II systolic murmur. This does not match the characteristics of a grade IV murmur, which is louder and more easily heard. Therefore, this description does not support a grade IV murmur.
D. A moderately loud murmur, without a thrill, could describe a grade III murmur. Additionally, a "machine-like rumble" is more characteristic of a diastolic murmur, such as those heard in conditions like aortic regurgitation or mitral stenosis, rather than a systolic murmur associated with mitral valve regurgitation.

Correct Answer is B
Explanation
A. The presence of crepitus, regardless of size, indicates air trapped in the subcutaneous tissue, which can be associated with various conditions including trauma, infection, or underlying lung issues. Therefore, it is important to evaluate the finding further rather than assuming it is insignificant.
B. This is the most accurate interpretation. Crepitus is indeed an abnormal finding and warrants further investigation. Its presence can indicate underlying issues such as subcutaneous emphysema, which may be related to trauma, infections, or other conditions that need to be addressed. A more detailed assessment, including possible imaging or additional diagnostic tests, should be pursued to determine the cause and appropriate management.
C. While it is true that subcutaneous air can be absorbed over time, the presence of crepitus is still an abnormal finding that needs to be evaluated. The underlying cause of the trapped air must be identified, as it may indicate an injury or other health issues that require intervention. Simply assuming that it will resolve on its own without further investigation could overlook a potentially serious condition.
D. While a fractured rib can cause crepitus, this finding alone does not necessarily mean an immediate chest x-ray is required. The decision to order an x-ray should be based on a comprehensive assessment of the client’s symptoms, history, and physical examination findings. Although a rib fracture is a possible cause, other conditions such as subcutaneous emphysema or infections should also be considered.
Correct Answer is A
Explanation
A. A urine dipstick test is a preliminary screening tool that can quickly provide information about the presence of glucose, protein, nitrites, and leukocytes in the urine. In the context of uncontrolled diabetes with symptoms of painful urination, this test is useful for identifying signs of a urinary tract infection (UTI), which is a common complication in diabetic patients.
B. A rapid strep test is used to diagnose streptococcal infections, particularly strep throat. It is not relevant to the symptoms of frequent and painful urination and does not help in assessing diabetic complications or urinary issues.
C. Nitrazine pH strips are primarily used to assess amniotic fluid in pregnant women to determine if labor has started. They are not used for diagnosing urinary tract infections or evaluating symptoms related to diabetes.
D. A fingerstick glucose test measures blood glucose levels and is useful for assessing the client's current glycemic control. While monitoring blood glucose levels is important for managing diabetes, it does not directly address the issue of painful urination or the presence of a urinary tract infection.
