Which oxygen delivery device can deliver 40-60% FIO2 and is from 5-8 L/min?

Nasal cannula

Simple face mask

Aerosol mask

Face tent

Answer and Explanation

The Correct Answer is B

A: A nasal cannula delivers a lower concentration of oxygen, typically between 24-44% FIO2, and is used at flow rates of 1-6 L/min. It is not suitable for delivering 40-60% FIO2.

B: A simple face mask can deliver 40-60% FIO2 at flow rates of 5-8 L/min. It covers the nose and mouth, providing a higher concentration of oxygen compared to a nasal cannula.

C: An aerosol mask is used for delivering humidified oxygen or medications via nebulization. It can deliver varying concentrations of oxygen but is not specifically designed for 40-60% FIO2 at 5-8 L/min.

D: A face tent is used for patients who cannot tolerate a mask, such as those with facial trauma or claustrophobia. It provides humidified oxygen but does not deliver a precise FIO2 concentration.

Correct Answer is C

Explanation

A: Calling the prescribing physician is important, but the immediate action should be to withhold the medication to prevent further elevation of potassium levels.

B: Calling the lab to verify the results can be done, but the immediate action should be to withhold the medication.

C: Omitting the KCL dose and documenting it is the correct action. The client’s potassium level is already elevated, and administering additional potassium could be harmful.

D: Giving the ordered KCL as prescribed is not appropriate because the client’s potassium level is already above the normal range.

A. Hyperkalemia B. Hyponatremia C. Hypervolemia D. Hypovolemia

Correct Answer is C

Explanation

A: Hyperkalemia refers to high potassium levels, which can occur in ESKD but does not directly cause shortness of breath, swelling, or crackles in the lungs.

B: Hyponatremia refers to low sodium levels, which can occur in ESKD but does not directly cause the symptoms described.

C: Hypervolemia, or fluid overload, is the most likely cause of the client’s symptoms. ESKD can lead to fluid retention, causing shortness of breath, swelling, crackles in the lungs, and elevated blood pressure.

D: Hypovolemia refers to low blood volume, which would not cause the symptoms of fluid overload described in the client.
