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 C
Explanation
pH 7.22: Indicates acidosis (normal range: 7.35-7.45).
PaCO2 68 mm Hg: Elevated partial pressure of carbon dioxide, suggesting respiratory acidosis (normal range: 35-45 mm Hg).
Base excess -2: Indicates a mild metabolic acidosis.
PaO2 78 mm Hg: Within the normal range (80-100 mm Hg), indicating adequate oxygenation.
Saturation 80%: Below the normal range (95-100%), suggesting some degree of hypoxemia.
Bicarbonate 26 mEq/L: Elevated bicarbonate levels, suggesting metabolic compensation for the respiratory acidosis.
Therefore, the client is experiencing respiratory acidosis with partial metabolic compensation (mild metabolic acidosis).
Correct Answer is B
Explanation
A. Myringotomy: Myringotomy is a procedure involving the insertion of tubes into the eardrum to treat conditions such as chronic ear infections. This procedure is not associated with a significant risk of deep-vein thrombosis.
B. Hip arthroplasty: Hip arthroplasty, or hip replacement surgery, is associated with an increased risk of deep-vein thrombosis due to factors such as immobility, surgical trauma, and alterations in blood flow. Prophylactic measures, such as anticoagulant medications and early ambulation, are often employed to reduce this risk.
C. Cataract extraction: Cataract extraction is a procedure to remove a cloudy lens from the eye. This surgery is not typically associated with a high risk of deep-vein thrombosis.
D. Laparoscopic appendectomy: Laparoscopic appendectomy, a minimally invasive procedure to remove the appendix, is generally associated with a lower risk of deep-vein thrombosis compared to major orthopedic surgeries like hip arthroplasty.
