Nokea
A client was exhibiting signs of mania and was recently started on lithium carbonate. She has no known physical problems. A teaching plan for this client would include which of the following?
- A. Regular foods should be eaten, including those that contain salt, such as bacon, ham, V-8 juice, and tomato juice.
- B. Restrict fluids to 1000 mL/day.
- C. Restrict foods that contain salt or sodium.
- D. Discontinue the medication if nausea occurs.
Correct Answer: A
Rationale: This answer is correct. A balanced diet with adequate salt intake is necessary. This answer is incorrect. The client must drink six to eight full glasses of fluid per day (2000-3000 mL/day). This answer is incorrect. The client should be instructed to avoid fluctuations of sodium intake. Diet should be balanced, with an adequate salt intake. This answer is incorrect. Nausea is a frequent side effect that can be minimized with administration of drug with meals or after eating food.

The nurse is assessing a client with suspected diabetic ketoacidosis. Which finding is most expected?
- A. Kussmaul respirations
- B. Hypertension
- C. Bradycardia
- D. Clear breath sounds
Correct Answer: A
Rationale: Kussmaul respirations (rapid, deep breathing) are a compensatory mechanism in diabetic ketoacidosis to eliminate excess carbon dioxide and correct acidosis. Hypotension, tachycardia, and clear breath sounds are more common.
The nurse is caring for a client with a history of Parkinson's disease. The nurse should expect the client to have:
- A. Tremors and rigidity

A client is placed on lithium therapy for her manic-depressive illness. When monitoring the client, the nurse assesses the laboratory blood values. Toxicity may occur with lithium therapy when the blood level is above:
- A. 1.0 mEq/L
- B. 2.2 mEq/L
- C. 0.03 mEq/L
- D. 1.5 mEq/L
Correct Answer: D
Rationale: This value is the level at which most clients are maintained, and toxicity may occur if the level increases. The client should be monitored closely for symptoms, because some clients become toxic even at this level.
The nurse instructs a pregnant client (G2P1) to rest in a side-lying position and avoid lying flat on her back. The nurse explains that this is to avoid 'vena caval syndrome,' a condition which:
- A. Occurs when blood pressure increases sharply with changes in position
- B. Results when blood flow from the extremities is blocked or slowed
- C. Is seen mainly in first pregnancies
- D. May require medication if positioning does not help
Correct Answer: B
Rationale: Vena caval syndrome occurs when the gravid uterus compresses the inferior vena cava, slowing blood return from the extremities.
A burn client's care plan reveals an expected outcome of no localized or systemic infection. Which assessment by the nurse supports this outcome?
- A. Wound culture results showing minimal bacteria
- B. Cloudy, foul-smelling urine
- C. White blood cell count of 14,000/mm3
- D. Temperature elevation of 101°F
Correct Answer: A
Rationale: Minimal bacteria in wound cultures indicates no localized infection, supporting the outcome. Cloudy urine (B), elevated WBC (C), and fever (D) suggest possible infection.
