A nurse is reviewing the laboratory values for an adolescent who is scheduled for a surgical procedure.
For which of the following laboratory values should the nurse notify the provider?
Platelet count 120,000/mm².
WBC count 9,800/mm³.
Hgb 13 mg/dL.
Hct 42%.
The Correct Answer is A
The nurse should notify the provider because this value is lower than the normal range of 150,000 to 450,000 platelets per microliter of blood. A low platelet count can indicate a risk of bleeding or a condition such as thrombocytopenia or disseminated intravascular coagulation (DIC).
Choice B is wrong because WBC count 9,800/mm³ is within the normal range of 4,500 to 11,000 cells per microliter of blood.
Choice C is wrong because Hgb 13 mg/dL is within the normal range of 12 to 16 mg/dL for females and 14 to 18 mg/dL for males.
Choice D is wrong because Hct 42% is within the normal range of 37% to 47% for females and 42% to 52% for males.

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.

Correct Answer is C
Explanation
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.
