AACN CCRN-Adult Exam With Confidence Using Practice Dumps

When a physician has attempted to insert a central line multiple times without success, the nurse's responsibility includes ensuring patient safety and advocating for the patient. Continued attempts by the same physician may increase the risk of complications, such as infection or trauma. Therefore, the nurse should suggest that another physician, possibly one with more experience or skill in central line insertion, perform the procedure.

The patient's ABG results indicate respiratory acidosis (pH 7.33, PaCO2 48 mm Hg) with a slightly elevated temperature (103.2° F). In the context of fever and acidosis, hemoglobin's affinity for oxygen decreases, a phenomenon described by the Bohr effect. This means that hemoglobin will release oxygen more readily to the tissues. Factors like increased temperature and acidosis cause a rightward shift in the oxyhemoglobin dissociation curve, reducing the affinity of hemoglobin for oxygen.References: = CCRN Exam Handbook, page 44

The patient’s findings are consistent with a ruptured diaphragm, which is a tear in the muscle that separates the chest and abdominal cavities. A blunt chest trauma can cause a sudden increase in intra-abdominal pressure, which can rupture the diaphragm and allow abdominal organs to herniate into the thorax. This can cause dyspnea, hypotension, shoulder pain, and bowel sounds over the lower thorax. A ruptured abdominal viscus would cause peritonitis, which would present with abdominal pain, distension, fever, and signs of sepsis. A flail chest would cause paradoxical chest movement, respiratory distress, and cyanosis. A mediastinal shift would cause tracheal deviation, decreased breath sounds, and jugular venous distension.
