NurseDive Free Nursing Practice Question
The nurse auscultates a systolic murmur in the second intercostal space to the right of the sternum while performing a cardiac assessment on a client. The nurse interprets this finding as:
A. An occlusion of the right coronary artery
This is not a correct interpretation. An occlusion of the right coronary artery is a blockage of the blood flow to the right side of the heart, which can cause a heart attack or ischemia. This condition does not produce a systolic murmur, but rather chest pain, shortness of breath, sweating, or nausea. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.
B. An aneurysm of the descending aorta
This is not a correct interpretation. An aneurysm of the descending aorta is a bulging or weakening of the wall of the large artery that carries blood from the heart to the lower body. This condition does not produce a systolic murmur, but rather a pulsating mass in the abdomen, back pain, or abdominal pain. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.
C. Decreased fluid in the pericardial sac
This is not a correct interpretation. Decreased fluid in the pericardial sac is a condition where the amount of fluid that surrounds and cushions the heart is reduced. This can be caused by dehydration, infection, or inflammation. This condition does not produce a systolic murmur, but rather a pericardial friction rub, which is a scratching or grating sound that occurs when the layers of the pericardium rub against each other. A systolic murmur is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve.
D. Distortion of one or more heart valves
This is the correct interpretation. Distortion of one or more heart valves is a condition where the shape or function of the valves that regulate the blood flow through the heart is altered. This can be caused by congenital defects, rheumatic fever, endocarditis, or aging. This condition can produce a systolic murmur, which is a sound that occurs during the contraction of the heart, when the blood flows through a narrowed or leaky valve. The location and the intensity of the murmur can help identify which valve is affected. A systolic murmur in the second intercostal space to the right of the sternum can indicate a problem with the aortic valve.

The nurse should instruct a young female adult with sickle cell anemia to do which of the following?
A. Avoid travel to cities where the oxygen level is lower
This is incorrect. Traveling to cities where the oxygen level is lower, such as high-altitude areas, can trigger a sickle cell crisis by reducing the amount of oxygen in the blood. People with sickle cell anemia should avoid such places or take precautions such as using supplemental oxygen¹².
B. Strenuous exercise prevents the development of sickle cell crisis
This is incorrect. Strenuous exercise does not prevent sickle cell crisis, but rather can cause it by increasing the body's oxygen demand and dehydration. People with sickle cell anemia should avoid overexertion and rest frequently during physical activity¹³.
C. Avoid flying on commercial airlines
This is incorrect. Flying on commercial airlines is not prohibited for people with sickle cell anemia, as long as they stay hydrated and avoid alcohol and caffeine. However, some people may need to use supplemental oxygen during flights, especially if they have a history of acute chest syndrome or pulmonary hypertension¹⁴.
D. Drink plenty of fluids when outside in hot weather
This is correct. Drinking plenty of fluids when outside in hot weather is important for people with sickle cell anemia, as dehydration can cause the red blood cells to sickle and block blood vessels. Staying hydrated can help prevent or reduce the severity of sickle cell crises¹⁵.

The nurse should instruct a young female adult with sickle cell anemia to do which of the following? (Select all that apply)
A. Be aware that pregnancy with sickle cell disease increases the risk of crisis
Pregnancy can increase the frequency and severity of sickle cell crises⁵⁶. Regular prenatal care is especially important for women with sickle cell disease⁵⁶. Therefore, it's crucial for a young female adult with sickle cell anemia to be aware that pregnancy increases the risk of crisis.
B. Avoid travel to cities where the oxygen level is lower
Low oxygen levels can trigger a sickle cell crisis³. Therefore, avoiding travel to cities where the oxygen level is lower can help prevent crises.
C. Strenuous exercise prevents the development of sickle cell crisis
While regular, moderate exercise can be beneficial, strenuous exercise can lead to dehydration and fatigue, which can trigger a sickle cell crisis⁹[^10^]¹¹. Therefore, the statement that strenuous exercise prevents the development of sickle cell crisis is not accurate.
D. Avoid flying on commercial airlines
Commercial airlines have controlled cabin pressure and oxygen levels, so flying is generally safe for individuals with sickle cell disease¹²³. However, it's always best to discuss travel plans with a healthcare provider³. Therefore, avoiding flying on commercial airlines is not necessarily a requirement.
E. Avoid drinking water on hot days.
Dehydration can increase the risk of a sickle cell crisis, so it's important to drink plenty of fluids, especially in hot weather³.

A client reports weakness, dizziness, nausea and vomiting that has lasted for three days. The nurse's assessment reveals dry tongue and oral mucosa, and dark concentrated urine. Which additional assessment would best evaluate the client's fluid status?
A. Respiratory rate and depth
This is not the best answer. Respiratory rate and depth can indicate the client's oxygenation and ventilation, but not necessarily their fluid status. The client may have normal or increased respiratory rate and depth due to dehydration, acidosis, or anxiety, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's respiratory rate and depth, but also assess other parameters of fluid status.
B. Rectal temperature
This is not the best answer. Rectal temperature can indicate the client's core body temperature, but not necessarily their fluid status. The client may have normal or elevated rectal temperature due to infection, inflammation, or dehydration, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's rectal temperature, but also assess other parameters of fluid status.
C. Blood pressure lying, sitting and standing
This is the best answer. Blood pressure lying, sitting and standing can indicate the client's fluid status and vascular tone. The client may have low blood pressure due to fluid loss, hypovolemia, or vasodilation, and this can cause orthostatic hypotension, which is a drop in blood pressure when changing positions. The nurse should measure the client's blood pressure in different positions and observe for signs of orthostatic hypotension, such as dizziness, fainting, or blurred vision.
D. Pulse oximetry reading at rest
This is not the best answer. Pulse oximetry reading at rest can indicate the client's oxygen saturation, but not necessarily their fluid status. The client may have normal or decreased pulse oximetry reading due to hypoxia, anemia, or poor peripheral perfusion, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's pulse oximetry reading, but also assess other parameters of fluid status.
