Exam Preview for 6772: Lab Values And Vital Signs As Clinical Monit

Lab Values And Vital Signs As Clinical Monitoring Tools For Patient Safety

Please note: exam questions are subject to change.

1. Which of the following best describes a critical lab value? A value that is significantly above or below the normal range but does not require immediate action A value that is only used as a reference for monitoring long-term health conditions A physiological state that is life-threatening unless promptly addressed with corrective action A value that requires intervention only if symptoms are present
2. Which of the following resting vital signs would most likely indicate the need to defer rehabilitation intervention? Heart rate of 90 bpm, blood pressure of 120/80 mmHg, and respiratory rate of 16 bpm Heart rate of 130 bpm, blood pressure of 150/95 mmHg, and oxygen saturation of 91% Heart rate of 110 bpm, blood pressure of 145/90 mmHg, and respiratory rate of 18 bpm Heart rate of 80 bpm, blood pressure of 135/85 mmHg, and respiratory rate of 14 bpm
3. Which of the following is the primary physiological impact of low hemoglobin levels? Increased risk of infection and delayed wound healing Impaired cognitive function and increased risk of seizures Decreased oxygen-carrying capacity leading to increased cardiac workload Increased risk of spontaneous blood clot formation
4. According to the HFH guidelines, what action should be taken if a patient’s potassium level is 6.2 mEq/L? Proceed with therapy as long as the patient is asymptomatic Defer physical and occupational therapy for that day Initiate therapy but monitor vitals continuously Reduce therapy intensity and limit exercise duration
5. Which of the following statements is TRUE regarding troponin levels and rehabilitation intervention? A troponin level above 100 ng/mL automatically allows for therapy initiation. Therapy should be deferred until 48 hours after a troponin peak, regardless of stability. If troponin is trending down and more than 24 hours have passed since a new peak, therapy may be initiated if the patient is hemodynamically stable. Troponin elevation always indicates an acute myocardial infarction (MI), requiring deferral of therapy
