A nurse is monitoring a client who is receiving a unit of packed RBCs following surgery. Which of the following assessments is an indication that the client might be experiencing a hemolytic reaction?

Choice A reason: Injecting the medication into the abdomen above the level of the iliac crest is the correct action. This is the preferred site for heparin administration, as it has fewer blood vessels and nerves, and allows for better absorption of the medication. The nurse should avoid the area around the umbilicus, as it may have increased bleeding and bruising.

Choice B reason: Massaging the injection site after administration of the medication is not the correct action. This may cause hematoma formation, tissue irritation, and reduced effectiveness of the medication. The nurse should apply gentle pressure to the injection site for 1 to 2 minutes after administration.

Choice C reason: Using a 1-inch needle to inject the medication is not the correct action. This may cause pain, tissue damage, and bleeding. The nurse should use a 25- to 28-gauge needle that is 3/8 to 5/8 inch long to inject the medication.

Choice D reason: Using a 22-gauge needle to inject the medication is not the correct action. This may cause pain, tissue damage, and bleeding. The nurse should use a 25- to 28-gauge needle that is 3/8 to 5/8 inch long to inject the medication.

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.
