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 C
Explanation
The correct answer is choice C. Allergy to gelatin is a contraindication for the inactivated influenza vaccine because gelatin is one of the ingredients in the vaccine. People with severe, life-threatening allergies to any ingredient in a flu vaccine (other than egg proteins) should not get that vaccine.
Choice A is wrong because pregnancy is not a contraindication for the inactivated influenza vaccine. In fact, pregnant people are recommended to get a flu shot because they are at higher risk of developing serious flu complications.
Choice B is wrong because immunosuppression is not a contraindication for the inactivated influenza vaccine. People with weakened immune systems can get a flu shot, but they should avoid the nasal spray flu vaccine which contains live viruses.
Choice D is wrong because moderate illness with fever is not a contraindication for the inactivated influenza vaccine. People who are moderately ill can still get a flu shot, but they should wait until they recover if they have a severe illness.
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.
