A nurse is reviewing laboratory results of a client who has atrial fibrillation and is taking warfarin. For which of the following results should the nurse notify the provider?
Platelets 190,000/mm3
Hct 44%
PT 45 seconds
Hgb 16 g/dL
The Correct Answer is C
Choice A reason: Platelets 190,000/mm3 is within the normal range of 150,000 to 450,000/mm3. This result does not indicate a bleeding risk or a need to adjust the warfarin dose.
Choice B reason: Hct 44% is within the normal range of 37% to 47% for females and 42% to 52% for males. This result does not indicate anemia or polycythemia, which could affect the warfarin therapy.
Choice C reason: PT 45 seconds is above the normal range of 11 to 13.5 seconds. This result indicates that the blood is taking too long to clot, which increases the risk of bleeding. The nurse should notify the provider and expect a decrease in the warfarin dose.
Choice D reason: Hgb 16 g/dL is within the normal range of 12 to 16 g/dL for females and 14 to 18 g/dL for males. This result does not indicate anemia or polycythemia, which could affect the warfarin therapy.

Correct Answer is A
Explanation
Choice A reason: Suppressing respiratory effort is the correct purpose of pancuronium. Pancuronium is a neuromuscular blocking agent that paralyzes the skeletal muscles, including the respiratory muscles. This prevents the client from breathing spontaneously and allows the mechanical ventilator to control the ventilation. Pancuronium is used to improve oxygenation and prevent barotrauma in clients with ARDS, who have severe hypoxemia and stiff lungs.
Choice B reason: Decreasing chest wall compliance is not the correct purpose of pancuronium. Chest wall compliance is the measure of how easily the chest wall expands during inspiration. Decreasing chest wall compliance means increasing the resistance to lung expansion, which can worsen the ventilation and oxygenation in clients with ARDS. Pancuronium does not affect the chest wall compliance, but rather the muscle tone.
Choice C reason: Decreasing respiratory secretions is not the correct purpose of pancuronium. Respiratory secretions are the mucus and fluid that are produced by the respiratory tract to moisten and protect the airways. Decreasing respiratory secretions can cause dryness and irritation of the mucous membranes, which can increase the risk of infection and inflammation. Pancuronium does not affect the respiratory secretions, but rather the nerve impulses.
Choice D reason: Inducing sedation is not the correct purpose of pancuronium. Sedation is a state of reduced consciousness, awareness, or responsiveness. Inducing sedation can help to reduce anxiety, pain, and agitation in clients who are mechanically ventilated. Pancuronium does not induce sedation, but rather paralysis. Pancuronium does not affect the central nervous system, but rather the peripheral nervous system. The nurse should administer a sedative agent, such as propofol or midazolam, along with pancuronium to ensure the client's comfort and safety.
Correct Answer is D
Explanation
Choice A reason: Vomiting is not a specific sign of a hemolytic reaction, as it can be caused by many other factors, such as anesthesia, infection, or medication. Vomiting may occur in other types of transfusion reactions, such as allergic or febrile reactions, but it is not indicative of hemolysis.
Choice B reason: Flushing is not a specific sign of a hemolytic reaction, as it can be caused by many other factors, such as fever, infection, or medication. Flushing may occur in other types of transfusion reactions, such as allergic or febrile reactions, but it is not indicative of hemolysis.
Choice C reason: Dyspnea is often linked with transfusion-associated circulatory overload (TACO) or transfusion-related acute lung injury (TRALI). Both of these conditions primarily impact the respiratory system, leading to difficulty breathing. Although respiratory symptoms can accompany severe reactions, dyspnea is not a key feature of a hemolytic reaction.
Choice D reason: Hypotension is a significant indicator of an acute hemolytic reaction. When the recipient’s immune system attacks the donor red blood cells, widespread inflammatory and immune responses occur, leading to vascular collapse. This can manifest as sudden low blood pressure, which is life-threatening if not recognized and treated immediately. Alongside other findings such as fever, chills, flank pain, and hemoglobinuria, hypotension is a classic hallmark of hemolysis during transfusion.
