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 D
Explanation
A. Varicosities, or varicose veins, are dilated veins that appear on the skin and are often associated with venous insufficiency. While they can be symptomatic and require management, they typically do not constitute an immediate medical emergency. Varicosities are generally managed with lifestyle changes, compression therapy, or medical procedures, but they are not usually life-threatening.
B. Lack of hair growth on the lower legs can indicate poor circulation, commonly seen in conditions like peripheral arterial disease (PAD). While it is a concerning finding and suggests potential arterial insufficiency, it is not usually an immediate emergency.
C. A Stage 2 pressure injury is characterized by partial-thickness loss of dermis, presenting as a shallow, open ulcer with a pink wound bed. While it requires attention to prevent progression and manage the wound, it is not an immediate emergency compared to other findings that suggest acute complications.
D. Right calf swelling and tenderness are critical findings that could indicate a deep vein thrombosis (DVT), which is a serious condition where a blood clot forms in a deep vein, usually in the leg. DVT can lead to life-threatening complications such as pulmonary embolism if the clot dislodges and travels to the lungs.
Correct Answer is C
Explanation
A. Auscultating all lobes of the lungs is an important step in a comprehensive respiratory assessment. It helps the nurse assess the presence and distribution of abnormal breath sounds, such as wheezing, and evaluate the overall condition of the lungs. While this is a crucial part of the assessment process, it is more of a diagnostic step rather than an immediate intervention for managing respiratory distress.
B. Placing the client in a low Fowler's position (45 degrees) can help improve ventilation and comfort, especially if they are experiencing difficulty breathing. However, in the context of audible wheezing and elevated respiratory rate, more immediate interventions to address the underlying issue are typically required.
C. Administering a respiratory aerosol treatment (such as a bronchodilator) is a direct intervention to address wheezing, which is often caused by bronchoconstriction or inflammation. Aerosol treatments can help open the airways and relieve wheezing, making this a priority action for managing the symptoms described.
D. Providing supplemental oxygen can be beneficial if the client is experiencing hypoxia (low blood oxygen levels). However, the need for oxygen should be determined based on the client's oxygen saturation levels and overall clinical picture. While oxygen can support breathing, it does not address the underlying cause of wheezing or the elevated respiratory rate directly.
