A nurse is caring for a client at a follow-up visit who has been taking lithium therapy for bipolar disorder.
Which of the following findings should indicate to the nurse that the client is experiencing lithium toxicity?
Hypoglycemia.
Excess salivation.
Urinary retention.
Dysrhythmia.
The Correct Answer is D
Dysrhythmia is an abnormal heart rhythm that can be a sign of severe lithium toxicity.
Lithium toxicity can occur when a person takes too much lithium, a mood- stabilizing medication used to treat bipolar disorder and major depressive disorder.
Choice A is wrong because hypoglycemia is not a symptom of lithium toxicity. Hypoglycemia is low blood sugar that can cause symptoms such as shakiness, sweating, hunger, and confusion.
Choice B is wrong because excess salivation is not a symptom of lithium toxicity. Excess salivation can be caused by various factors, such as infections, medications, or nerve damage.
Choice C is wrong because urinary retention is not a symptom of lithium toxicity. Urinary retention is the inability to empty the bladder completely, which can cause pain, discomfort, and infection. Lithium toxicity can actually cause increased urine output, not decreased.
Normal ranges for blood lithium levels are 0.6 to 1.2 mEq/L for maintenance therapy and 0.8 to 1.5 mEq/L for acute therapy. Levels above 1.5 mEq/L can cause mild to moderate toxicity, and levels above 2.0 mEq/L can cause severe toxicity. Levels above 3.0 mEq/L are considered a medical emergency.

Correct Answer is B
Explanation
This statement indicates that the client has orthopnea, which is a sign of worsening heart failure and fluid overload. The nurse should intervene by assessing the client’s vital signs, oxygen saturation, lung sounds, and edema, and notifying the provider for possible diuretic adjustment.
Choice A is wrong because “I’m urinating in larger amounts.” is an expected outcome of taking furosemide, which is a loop diuretic that increases urine output and reduces fluid retention.
Choice C is wrong because “I suck on hard candy for my dry mouth.” is a harmless way to cope with the side effect of dry mouth caused by furosemide.
Choice D is wrong because “I’ve lost 3 pounds in the last week.” is a positive sign that the client is losing excess fluid and improving their heart failure
condition. A weight loss of 2 to 4 pounds per week is acceptable for clients taking diuretics.
Normal ranges for heart failure clients are:
- Blood pressure: less than 140/90 mmHg
- Heart rate: 60 to 100 beats per minute
- Respiratory rate: 12 to 20 breaths per minute
- Oxygen saturation: greater than 95%
- Weight: stable or decreasing within 2 to 4 pounds per week
Correct Answer is B
Explanation
Justice is the ethical principle of treating the patient fairly and equally among staff when making assignments. The charge nurse is upholding this principle by ensuring that the workload is distributed evenly and that no staff member is overburdened or underutilized.
Choice A is wrong because Veracity is wrong because veracity is the ethical principle of telling the truth to the patient.
This principle is not relevant to the scenario of making assignments.
Choice C is wrong because Autonomy is wrong because autonomy is the ethical principle of respecting the patient’s right to make their own healthcare decisions.
This principle is not relevant to the scenario of making assignments.
Choice D is wrong because Fidelity is wrong because fidelity is the ethical principle of keeping promises to the patient.
This principle is not relevant to the scenario of making assignments.
