A nurse is caring for a client who is receiving oxygen via nasal cannula at 4 L/min. Which of the following actions should the nurse take?
Avoid the use of humidifiers.
Position the cannula prongs curving upward in the nose.
Clean the cannula prongs daily.
Keep the oxygen tubing off the floor.
The Correct Answer is C
Clean the cannula prongs daily.
This is because the nasal cannula can become contaminated with bacteria and mucus, which can cause infection and irritation of the nasal mucosa. Cleaning the cannula prongs daily with soap and water can prevent these complications.
Choice A is wrong because humidifiers can help moisten the dry oxygen and prevent nasal dryness and bleeding. Humidifiers should be used for oxygen flow rates higher than 4 L/min.
Choice B is wrong because the cannula prongs should be positioned curving downward in the nose, not upward. This allows for better alignment with the natural direction of airflow and reduces the risk of dislodgement.
Choice D is wrong because keeping the oxygen tubing off the floor is not a specific action for nasal cannula use. It is a general safety measure to prevent tripping and contamination of the tubing.

Correct Answer is D
Explanation
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 D
Explanation
Insulin lispro was administered to a client immediately before bed. This is a situation that requires the completion of an incident report because insulin lispro is a rapid-acting insulin that should be given within 15 minutes before or after a meal. Giving it immediately before bed can cause hypoglycemia (low blood sugar) during the night, which can be dangerous for the client.
Choice A is wrong because nitroglycerin transdermal is a medication used to prevent angina (chest pain) and can be applied to a client’s chest as prescribed.
Choice B is wrong because cefotaxime is an antibiotic that can be administered to a client after obtaining blood cultures to treat an infection.
Choice C is wrong because digoxin is a medication used to treat heart failure and atrial fibrillation and can be administered to a client who has a heart rate of 64/min, which is within the normal range of 60 to 100 beats per minute.
