The nurse continues to care for the client.

For each assessment finding, click to specify if the finding is consistent with psychosis or mania. Each finding may support more than one diagnosis.

Rationale for correct choices

• Heart sounds: The presence of S3 and S4 heart sounds may indicate right ventricular strain or acute heart failure, which can occur secondary to a massive pulmonary embolism. This finding aligns with increased cardiac workload due to impaired pulmonary circulation. Heart sounds are not typically altered in pneumonia or pneumothorax unless severe cardiac compromise occurs.

• Respiratory pattern: Tachypnea and labored breathing can occur in all three conditions. In pulmonary embolism, rapid breathing compensates for hypoxemia. In pneumonia, increased respiratory rate results from impaired gas exchange and inflammation. In pneumothorax, rapid breathing occurs due to decreased lung expansion and oxygenation.

• Temperature: Fever (38.9° C/102° F) suggests an infectious process, consistent with pneumonia. Pulmonary embolism and pneumothorax typically do not present with elevated temperature unless secondary infection or inflammatory response is present.

• Lung sounds: Bilateral crackles indicate fluid or exudate in the alveoli. In pneumonia, crackles result from consolidation and inflammation. In pulmonary embolism, crackles may reflect pulmonary infarction or edema from right-sided heart strain. Pneumothorax generally produces absent or decreased breath sounds rather than crackles, so crackles are less indicative.

Rationale for correct choice

• Fall risk: The client experiences sudden episodes of leg weakness, intermittent muscle spasms, and gait changes, all of which significantly increase the risk of falls. Falls in clients with multiple sclerosis can lead to serious injury and further functional decline. Addressing safety and fall prevention is the most immediate priority to prevent harm while other concerns, such as memory or employment, are addressed.

Rationale for incorrect choices

• Memory: Although the client reports struggling to remember things, cognitive issues are not immediately life-threatening. Memory deficits should be addressed through ongoing assessment and cognitive support interventions, but they are not the first priority compared with safety risks.

• Blood pressure: Vital signs are within normal limits, and there is no evidence of hypertensive crisis or acute cardiovascular instability. Blood pressure monitoring remains part of routine care but does not require immediate intervention.

• BMI: The client’s BMI indicates overweight status but does not pose an immediate safety threat. Weight management is important for long-term health but is not the first priority in the context of neurological deficits and fall risk.

• Employment: Reduced work hours due to exacerbation episodes reflect functional limitations and psychosocial impact. Employment concerns are important for quality of life but are secondary to preventing physical injury from falls.
