A patient with chronic obstructive pulmonary disease (COPD) is admitted for worsening dyspnea and possible pneumonia. The current ABG results are pH, 7.19; PaO2, 52 mm Hg; PaCO2, 68 mm Hg; HCO3 - , 32 mmol/L. The nurse would interpret these results as
A. Metabolic acidosis with hypoxemia
B. Respiratory acidosis with hypoxemia
C. Respiratory alkalosis with typical oxygenation for a COPD patient
D. Metabolic alkalosis with typical oxygenation for a COPD patient - B.
Based on the ABG analysis, the patient is experiencing a respiratory acidosis with hypoxemia most likely due to the pneumonia. A pH of 7.19 indicates acidosis; a PaCO2 of 68 mm Hg is elevated and a cause of acidosis; an HCO3 - of 32 mmol/L indicates renal compensation; a PaO2 of 52 mm Hg indicates hypoxemia
76-year-old patient is receiving gentamicin and linezolid for an infection. Which of the following potential complications is the most important for the nurse to monitor this patient for?
A. Acute delirium
B. Acute kidney injury
C. Acute hepatic failure
D. Sepsis - B.
Gentamicin is a nephrotoxic agent that places patients at risk for acute kidney injury, and this risk is increased in older patients. Acute delirium (A), liver failure (C), and sepsis (D) are all complications that could occur in an older adult with an infection but would not be caused by the administration of an antibiotic.
An older patient is experiencing delirium 24 hours following hip replacement. Which intervention might worsen the patient's condition?
A. Removing any unnecessary tubes and equipment from the room
B. Assessing and treating the patient's pain every 2 hours
C. Ensuring that the patient has the means to call for help
D. Loosely applying soft restraints - D.
Older patients are at increased risk for delirium during acute hospitalization. Interventions to manage acute delirium include removing or camouflaging tubes, removing unnecessary equipment, frequently reorienting the patient, and ensuring that the call bell is consistently within reach, assessing and treating pain effectively, and encouraging mobility and involvement in activities of daily living. Restraining the patient is contraindicated in the care of patients with delirium.
