A nurse is monitoring the pulmonary artery wedge pressure (PAWP) for a client. The nurse should identify that a reading of 17 mm Hg is an indication of which of the following conditions?
Right ventricular failure
Fluid volume deficit
Mitral regurgitation
Afterload reduction
The Correct Answer is C
Choice A Reason: This is incorrect because right ventricular failure would cause an increase in right atrial pressure and right ventricular end-diastolic pressure, but not in PAWP, which reflects left atrial pressure and left ventricular end- diastolic pressure.
Choice B Reason: This is incorrect because fluid volume deficit would cause a decrease in PAWP, as there would be less blood volume in the pulmonary circulation.
Choice C Reason: This is correct because mitral regurgitation would cause an increase in PAWP, as the blood would back up into the left atrium and pulmonary veins due to the incompetent mitral valve.
Choice D Reason: This is incorrect because afterload reduction would cause a decrease in PAWP, as there would be less resistance to the left ventricular ejection and less blood volume in the pulmonary circulation.

Correct Answer is B
Explanation
Choice A Reason: This is incorrect because the client is not unconscious, as the GCS score ranges from 3 to 15, with 3 being the lowest possible score and indicating deep coma or death.
Choice B Reason: This is correct because the client can follow simple motor commands, as the GCS score for best motor response is 5, which means the client can localize pain by moving his limbs away from the source of stimulation.To interpret the Glasgow Coma Scale (GCS) score provided in the scenario:Eye Opening (E): 3 - The client opens their eyes in response to verbal stimuli.Best Verbal Response (V): 5 - The client is oriented and able to engage in coherent conversation.Best Motor Response (M): 5 - The client can localize pain or follow motor commands (depending on additional context). The total GCS score would be 3 + 5 + 5 = 13, indicating a mild level of impairment or responsiveness.
Choice C Reason: This is incorrect because the client is able to make vocal sounds, as the GCS score for best verbal response is 5, which means the client can orient himself to person, place, and time.
Choice D Reason: This is incorrect because the client does not open his eyes when spoken to, as the GCS score for eye opening is 3, which means the client only opens his eyes in response to pain.
Correct Answer is B
Explanation
Choice A Reason: This is incorrect because preparing for mechanical ventilation is not the priority nursing intervention, as it is an invasive and potentially harmful procedure that should be reserved for clients who have severe respiratory failure and cannot maintain adequate oxygenation with noninvasive methods.
Choice B Reason: This is correct because administering oxygen via face mask is the priority nursing intervention, as it is a noninvasive and effective way to improve oxygenation and reduce hypoxemia in a client who has low PaO2 and SaO2. Oxygen therapy can also decrease the workload of the heart and lungs and prevent further complications.
Choice C Reason: This is incorrect because preparing to administer a sedative is not the priority nursing intervention, as it may worsen the client's respiratory status and mask the signs and symptoms of hypoxemia. Sedatives should be used with caution and only after oxygenation has been optimized.
Choice D Reason: This is incorrect because assessing for indications of pulmonary embolism is not the priority nursing intervention, as it is a diagnostic rather than a therapeutic action. Pulmonary embolism is a possible cause of the client's condition, but it does not address the immediate problem of hypoxemia.
