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.

The nurse is encouraging the client to cough and deep breathe after cardiac surgery. The nurse ensures that which item is available to maximize the effectiveness of this procedure?
- A. Nebulizer
- B. Ambu bag
- C. Suction equipment
- D. Incisional splinting pillow
Correct Answer: D
Rationale: The use of an incisional splint such as a 'cough pillow' can ease discomfort during coughing and deep breathing. The client who is comfortable will do more effective deep breathing and coughing exercises. Use of an incentive spirometer is also indicated. Options 1, 2, and 3 will not encourage the client to cough and deep breathe.
A client prescribed lithium carbonate for the treatment of bipolar disorder has a medication blood level of 1.6 mEq/L (1.6 mmol/L). Which assessment question should the nurse ask to determine whether the client is experiencing signs of lithium toxicity associated with this level?
- A. Do you hear ringing in your ears?
- B. Have you noted that your vision is blurred?
- C. Have you fallen recently because you are dizzy?
- D. Have you been experiencing any nausea, vomiting, or diarrhea?
Correct Answer: D
Rationale: Normal lithium levels are between 0.8 to 1.2 mEq/L (0.8 to 1.2 mmol/L). One of the most common early signs of lower level lithium toxicity is gastrointestinal (GI) disturbances such as nausea, vomiting, or diarrhea. The assessment questions in options 1, 2, and 3 are related to the findings in lithium toxicity at higher levels.
An assessment of a client's vocal cords requires indirect visualization of the larynx. Which instruction should the nurse give the client to facilitate this procedure?
- A. Try to swallow.
- B. Hold your breath.
- C. Breathe normally.
- D. Roll the tongue to the back of the mouth.
Correct Answer: C
Rationale: Indirect laryngoscopy is done to assess the function of the vocal cords or obtain tissue for biopsy. Observations are made during rest and phonation by using a laryngeal mirror, head mirror, and light source. The client is placed in an upright position to facilitate passage of the laryngeal mirror into the mouth and is instructed to breathe normally. Swallowing cannot be done with the mirror in place. The procedure takes longer than the time the client would be able to hold the breath, and this action is ineffective anyway. The tongue cannot be moved back because it would occlude the airway.
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.
A primary health care provider prescribes acetaminophen liquid 450 mg orally every 4 hours PRN for pain. The medication label reads 160 mg/5 mL. The nurse prepares how many milliliters (mL) to administer one dose? Fill in the blank and record your answer to the nearest whole number.
Correct Answer: 14 mL
Rationale: Use the formula for calculating medication dosages. Formula: Desired × Volume / Available = mL per dose. 450 mg × 5 mL / 160 mg = 14 mL.
