After a client diagnosed with pleural effusion had a thoracentesis, a sample of fluid was sent to the laboratory. Analysis of the fluid reveals a high red blood cell count. Based on this test result, what was the cause of this client's pleural effusion?
- A. Trauma
- B. Infection
- C. Liver failure
- D. Heart failure
Correct Answer: A
Rationale: Pleural fluid from an effusion that has a high red blood cell count may result from trauma and may be treated with placement of a chest tube for drainage. Other causes of pleural effusion include infection, heart failure, liver or renal failure, malignancy, or inflammatory processes. Infection would be accompanied by white blood cells. The fluid portion of the serum would accumulate with liver failure and heart failure.

- B. Take the medication in the morning.

The client is told not to discontinue the medication and that thyroid replacement is lifelong. Additional instructions include contacting the primary health care provider if the rate is greater than 100 beats per minute and notifying the primary health care provider if chest pain occurs, or if weight loss, nervousness and tremors, or insomnia develops. The client is also told that full therapeutic effect may take 1 to 3 weeks and that he or she needs to have follow-up thyroid blood studies to monitor therapy.
The nurse should place a client who sustained a head injury in which position to prevent increased intracranial pressure (ICP)?
- A. In left Sims' position
- B. In reverse Trendelenburg
- C. With the head elevated on a small, flat pillow
- D. With the head of the bed elevated at least 30 degrees
Correct Answer: D
Rationale: The client with a head injury is positioned to avoid extreme flexion or extension of the neck and to maintain the head in the midline, neutral position. The head of the bed is elevated to at least 30 degrees or as recommended by the primary health care provider. The client is log rolled when turned to avoid extreme hip flexion.
The nurse is caring for a client who has been placed in skin traction. Which action by the nurse provides for countertraction to reduce shear and friction?
- A. Using a footboard
- B. Providing an overhead trapeze
- C. Slightly elevating the foot of the bed
- D. Slightly elevating the head of the bed
Correct Answer: C
Rationale: The part of the bed under an area in traction is usually elevated to aid in countertraction. For the client in skin traction (which is applied to a leg), the foot of the bed is elevated. Option 3 provides a force that opposes the traction force effectively without harming the client. A footboard, an overhead trapeze, or elevating the head of the bed is not used to provide countertraction.
