ATI Hemodynamic Monitoring Exam 2025 Questions and Answers Graded A

1. A nurse is evaluating the central venous pressure (CVP) of a client who has sustained multiple traumas. Which of the following interpretations of a low CVP pressure should the nurse make? A. Fluid overload Rationale: The CVP is the pressure in the vena cava, or right atrium, and is reflective of preload. A client who has fluid overload would have a high CVP value. B. Left ventricular failure Rationale: Left ventricular failure can be detected by an elevated pulmonary artery wedge pressure. C. Intracardiac shunt Rationale: Intracardiac shunt can be detected by an elevated pulmonary artery wedge pressure. D. Hypovolemia Rationale: A low CVP indicates reduced right ventricular preload, which can be seen in clients who are experiencing hypovolemia, excessive blood loss, or over diuresis - D. Hypovolemia 2. A nurse is monitoring the pulmonary artery wedge pressure (PAWP) for a client. The nurse should identity that a reading of 15 mm Hg is an indication of which of the following conditions? A. Fluid volume deficit Rationale: A client who has fluid volume deficit is more likely to have a decreased PAWP. B. Right ventricular failure Rationale: An increased right atrium (RA) pressure can indicate right ventricular failure. A decreased RA pressure usually indicates hypovolemia. C. Mitral regurgitation Rationale: Hemodynamic monitoring allows the nurse to monitor the pressures within the heart and the great vessels. The PAWP reflects left atrial pressure. A reading of 15 mm Hg is above the expected reference range, which can indicate mitral regurgitation, hypervolemia, or left ventricular failure. The nurse should monitor for trends in value, which can be more reliable than individual values. D. Afterload reduction Rationale: A client who has afterload reduction is more likely to have a decreased PAWP. - C. Mitral regurgitation PAWP. 3. A nurse is monitoring the cardiac output of a client who has left-sided heart failure using pulse pressure analysis. Which of the following findings can compromise the readings? A. The client is experiencing premature atrial contractions. Rationale: ATI Hemodynamic Monitoring Exam 2025 Questions and Answers Graded A Pulse pressure devices require the presence of optimal arterial waveforms in order to capture accurate data. Therefore, a dysrhythmia, such as premature atrial contractions, will compromise the readings. B. The client has a decreased oxygen saturation level. Rationale: Decreased oxygen saturation is a manifestation of heart failure that does not compromise cardiac output readings. C. The client has bilateral wheezes. Rationale: Bilateral wheezes are a manifestation of heart failure that do not compromise cardiac output readings. D. The client has lower leg edema. Rationale: Lower leg edema is a manifestation of heart failure that does not compromise cardiac output readings. - A. The client is experiencing premature atrial contractions.
