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.

A client experiencing empyema is to have a bedside thoracentesis performed. The nurse plans to have which equipment available in the event that the procedure is not effective?
- A. Code cart
- B. A small-bore needle
- C. Extra-large drainage bottle
- D. Chest tube and drainage system
Correct Answer: D
Rationale: Empyema is the collection of pus within the pleural cavity. If the exudate is too thick for drainage via thoracentesis, the client may require placement of a chest tube to adequately drain the purulent effusion. A small-bore needle would not effectively allow exudate to drain. Options 1 and 3 are also unnecessary.
The nurse provides dietary instructions to a client who needs to limit intake of sodium. The nurse instructs the client that which food items must be avoided because of their high sodium content? Select all that apply.
- A. Ham
- B. Apples
- C. Broccoli
- D. Soy sauce
- E. Asparagus
- F. Cantaloupe
Correct Answer: A,D
Rationale: Foods highest in sodium include table salt, some cheeses, soy sauce, cured pork, canned foods because of the preservatives, and foods such as cold cuts. Fruits and vegetables contain minimal amounts of sodium.
The nurse is caring for a client who had an orthopedic injury of the leg that required surgery and the application of a cast. Postoperatively, which nursing assessment is of highest priority to assure client safety?
- A. Monitoring for heel breakdown
- B. Monitoring for bladder distention
- C. Monitoring for extremity shortening
- D. Monitoring for blanching ability of toe nail beds
Correct Answer: D
Rationale: With cast application, concern for compartment syndrome development is of the highest priority. If postsurgical edema compromises circulation, the client will demonstrate numbness, tingling, loss of blanching of toenail beds, and pain that will not be relieved by opioids. Although heel breakdown, bladder distention, or extremity lengthening or shortening can occur, these complications are not potentially life-threatening complications.
Which nursing assessment question should be asked to help determine the client's risk for developing malignant hyperthermia in the perioperative period?
- A. Have you ever had heat exhaustion or heat stroke?
- B. What is the normal range for your body temperature?
- C. Do you or any of your family members have frequent infections?
- D. Do you or any of your family members have problems with general anesthesia?
Correct Answer: D
Rationale: Malignant hyperthermia is a genetic disorder in which a combination of anesthetic agents (the muscle relaxant succinylcholine and inhalation agents such as halothanes) triggers uncontrolled skeletal muscle contractions that can quickly lead to a potentially fatal hyperthermia. Questioning the client about the family history of general anesthesia problems may reveal this as a risk for the client. Options 1, 2, and 3 are unrelated to this surgical complication.
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.
