A nurse is instructing a newly licensed nurse on how to obtain a fecal occult blood test from a patient.
What information should the nurse include?
Apply four drops of developing solution to each stool specimen.
Use toilet paper to transfer the stool specimen.
Wait 30 seconds after applying the developing solution to obtain the results.
Collect two stool specimens from the same area of the stool.
Correct Answer : C
The correct answer is Choice C.
Choice A rationale: Applying four drops of developing solution to each stool specimen is incorrect. Typically, the test requires two drops of solution. Following manufacturer instructions ensures accurate results and prevents unnecessary waste or inaccurate readings.
Choice B rationale: Using toilet paper to transfer the stool specimen is improper. Stool should be collected using the provided applicator stick to avoid contamination, ensuring the accuracy of the fecal occult blood test.
Choice C rationale: Waiting 30 seconds after applying the developing solution allows the chemical reaction to complete, ensuring accurate detection of any occult blood present in the stool sample.
Choice D rationale: Collecting two stool specimens from the same area increases the risk of missing occult blood present in different parts of the stool. Sampling from multiple areas enhances test accuracy and ensures comprehensive results.

Correct Answer is ["D"]
Explanation
Choice A rationale:
Petroleum-based ointments like Vaseline are not recommended for moisturizing lips, especially for patients on oxygen therapy. This is because petroleum jelly is not effective at restoring moisture once it’s been lost. Moreover, it can feel heavy and slippery on the lips, and it’s not very eco-friendly.
Choice B rationale:
Oxygen tanks should be kept at a safe distance from heat sources, including electric stoves. However, the recommended distance is not 4 feet but rather at least 5-10 feet away. This is to minimize the risk of fire or combustion.
Choice C rationale:
Wool blankets are not recommended when using oxygen. Wool can cause a spark which can be dangerous around oxygen. It’s important to avoid anything that may cause a spark around home oxygen, including electric heaters, electric blankets, electric razors, hair dryers, or friction toys.
Choice D rationale:
Oxygen tanks should always be stored upright. This prevents any strain on the valves or other components and reduces the risk of damage and potential gas leaks.
Correct Answer is A
Explanation
Choice A rationale:
Mitral valve stenosis is a condition characterized by a narrowing of the mitral valve in the heart, which can lead to a variety of symptoms. One of the most common symptoms of mitral valve stenosis is a heart murmur. This is due to the turbulent flow of blood caused by the narrowed valve. The murmur is typically heard during a physical examination when a healthcare provider listens to the heart with a stethoscope.
Choice B rationale:
Bradycardia, or a slower than normal heart rate, is not typically associated with mitral valve stenosis. While mitral valve stenosis can cause irregular heart rhythms, it does not typically cause the heart rate to slow down.
Choice C rationale:
Clubbing of the fingers is a physical symptom that involves changes in the areas under and around the nails and is typically associated with conditions that cause chronic low blood oxygen levels. While mitral valve stenosis can lead to shortness of breath and fatigue, it does not typically cause clubbing of the fingers.
Choice D rationale:
A barrel chest, characterized by an increased chest diameter, is typically associated with conditions that cause chronic overinflation of the lungs, such as chronic obstructive pulmonary disease (COPD). It is not a typical symptom of mitral valve stenosis.
In conclusion, while mitral valve stenosis can lead to a variety of symptoms, the most relevant to this question is a heart murmur. Other symptoms such as bradycardia, clubbing of the fingers, and a barrel chest are not typically associated with this condition.
