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 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
The indirect Coombs test is used to detect antibodies against foreign red blood cells in the maternal serum. This test can help identify maternal-fetal blood incompatibility, which can cause hemolytic disease of the newborn.
Choice A is wrong because homocysteine is a type of amino acid and is not related to blood compatibility.
Choice C is incorrect because erythropoietin is a hormone that regulates red blood cell production and is not a specific test for detecting maternal-fetal blood incompatibility.
Choice D is not the correct answer as aPTT (activated partial thromboplastin time) is a test used to evaluate blood clotting factors and is not directly related to monitoring maternal-fetal blood incompatibility.
