Sample questions from Fatigue Sherpath Study Guide

This material has 12 questions with answers and rationales. Here are the first 5.

1. 1.A client reports increasing fatigue and black, sticky stools. Blood pressure is 88/52 mm Hg, heart rate is 124/min, and SpO2 is 98% on room air. Which action should the nurse take first?

   • A.Encourage the client to walk briefly to evaluate endurance.
   • B.Schedule an uninterrupted sleep period.
   • C.Activate the appropriate urgent response and assess circulation.
   • D.Provide teaching about increasing dietary iron.

   Rationale: B is correct because suspected bleeding with hypotension and tachycardia indicates possible shock requiring urgent intervention. A may be relevant later but does not address instability. C risks syncope and worsening physiologic stress. D delays emergency care. Normal SpO2 does not exclude blood loss or inadequate oxygen delivery.

2. 2.A client with hemoglobin 7.2 g/dL asks why walking causes fatigue when the pulse oximeter reads 97%. Which explanation is best?

   • A.Anemia causes fatigue only when oxygen saturation is below 90%.
   • B.The device estimates hemoglobin saturation, not how much hemoglobin is available to carry oxygen.
   • C.The reading shows that oxygen delivery to all tissues is normal.
   • D.The result confirms that the fatigue is caused by poor sleep.

   Rationale: C is correct because oxygen saturation does not measure hemoglobin concentration or total oxygen content. A incorrectly equates saturation with tissue delivery. B incorrectly requires hypoxemia for anemia-related symptoms. D assigns a cause without supporting assessment.

3. 3.Which client statement indicates a need for further teaching about levothyroxine?

   • A.I expect improvement to occur gradually rather than immediately.
   • B.I will keep the laboratory appointment after my dose change.
   • C.I will take it consistently as directed on an empty stomach.
   • D.I will take my iron tablet with levothyroxine to simplify my schedule.

   Rationale: D is correct because iron reduces levothyroxine absorption and should be separated by at least four hours. A supports consistent absorption. B reflects the expected gradual response. C supports monitoring of treatment and dose adjustment.

4. 4.An RN is caring for a stable client with chronic fatigue and an established mobility plan. Which task is most appropriate to delegate to trained assistive personnel?

   • A.Assist the client with the planned transfer and report dizziness immediately.
   • B.Develop an individualized energy-conservation teaching plan.
   • C.Interpret orthostatic vital signs and change the activity prescription.
   • D.Determine whether new shortness of breath is related to anxiety.

   Answer and rationale are in the full material.

5. 5.A client with persistent fatigue reports feeling substantially worse the day after grocery shopping, with symptoms lasting three days. Which plan is most appropriate?

   • A.Assess for post-exertional malaise and plan activity within individual limits.
   • B.Use caffeinated energy drinks before demanding activities.
   • C.Avoid all physical and cognitive activity indefinitely.
   • D.Increase walking by a fixed amount each day regardless of symptoms.
