A nurse is reviewing the laboratory findings for a client who has idiopathic thrombocytopenic purpura (ITP). Which of the following findings should the nurse expect to be decreased?
RBC
Platelets
Granulocytes
WBC
The Correct Answer is B
A. RBC (Red Blood Cells): ITP primarily affects platelet levels, not red blood cells. Therefore, red blood cell counts are not typically decreased in ITP.
B. Platelets: This is the correct answer. ITP is characterized by a low platelet count due to immune-mediated destruction of platelets. A decreased platelet count can lead to an increased risk of bleeding.
C. Granulocytes: While ITP primarily affects platelets, it does not have a direct impact on granulocyte counts. Granulocytes are a type of white blood cell.
D. WBC (White Blood Cells): ITP primarily affects platelets, not white blood cells. Therefore, white blood cell counts are not typically decreased in ITP.

Correct Answer is D
Explanation
A. Aortic regurgitation: Aortic regurgitation typically presents with a diastolic murmur, not a systolic click.
B. Mitral stenosis: Mitral stenosis presents with a diastolic murmur, often associated with an opening snap, rather than a systolic click.
C. Aortic stenosis: Aortic stenosis typically presents with a systolic ejection murmur, but not a systolic click.
D. Mitral valve prolapse: This is the correct answer. Mitral valve prolapse (MVP) is characterized by the displacement of the mitral valve leaflets into the left atrium during systole, often producing a systolic click. Symptoms associated with MVP can include atypical chest pain, palpitations, and exercise intolerance.
Correct Answer is D
Explanation
A. Troponin is a lipid whose levels reflect the risk for coronary artery disease: This statement is incorrect. Troponin is not a lipid, and its levels do not reflect the risk for coronary artery disease. Troponin is a protein associated with muscle tissue.
B. Troponin is an enzyme that indicates damage to brain, heart, and skeletal muscle tissues: While troponin indicates damage to muscle tissues, it is specifically associated with cardiac muscle, not brain or skeletal muscle tissues.
C. Troponin is a protein that helps transport oxygen throughout the body: This statement is incorrect. While proteins in the blood may contribute to oxygen transport, troponin's primary role is in muscle contraction, particularly in the heart.
D. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart: This is the correct answer. Troponin is a protein found in cardiac muscle cells, and when there is damage to the heart, such as during a myocardial infarction, troponin is released into the bloodstream. Elevated troponin levels in the blood are indicative of myocardial injury or infarction.
