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?

A. Bradypnea: Bradypnea refers to abnormally slow breathing. In the context of postoperative atelectasis and hypoxia, the client is more likely to exhibit tachypnea (rapid breathing) as the body attempts to compensate for reduced oxygen levels.

B. Bradycardia: Bradycardia is an abnormally slow heart rate. While hypoxia can lead to changes in heart rate, it is more common to observe tachycardia (increased heart rate) as a compensatory response to decreased oxygen levels.

C. Intercostal retractions: Intercostal retractions occur when the muscles between the ribs pull inward during inspiration. In a client with atelectasis and hypoxia, increased respiratory effort may result in intercostal retractions as the body tries to enhance airflow and improve oxygenation.

D. Lethargy: Lethargy refers to a state of drowsiness or fatigue. While hypoxia can lead to lethargy, it is not a specific respiratory manifestation. Other respiratory signs, such as increased respiratory rate and retractions, are more likely to be observed.

Correct answer: C

A. Bumetanide 1 mg IV bolus every 12 hr is a loop diuretic used to help reduce fluid overload and manage heart failure symptoms. This medication helps remove excess fluid from the body and can be beneficial for a client with acute heart failure following an MI.

B. Laboratory testing of serum potassium upon admission: It is common to monitor serum potassium levels in patients receiving diuretics, especially loop diuretics, to prevent electrolyte imbalances.

C.Administering 0.9% normal saline IV at a continuous rate can potentially exacerbate heart failure by increasing fluid volume, leading to fluid overload and worsening symptoms. In acute heart failure, fluid management is critical, and fluids are typically restricted to prevent further strain on the heart.

D. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain: Morphine sulfate is prescribed for pain management and is commonly used in acute heart failure situations to relieve anxiety and decrease preload on the heart. The dosing frequency is appropriate as "every 2 hr PRN" indicates it should be administered as needed for pain relief.
