A nurse is assisting with the care of a patient who is receiving supplemental oxygen for hypoxia.
Which of the following findings should the nurse identify as an indication that the intervention was effective?
Respiratory rate 28/min.
Pink mucous membranes.
Heart rate 110/min.
Restlessness.
Restlessness.
The Correct Answer is B
Choice A rationale:
A respiratory rate of 28/min is not an indication that the intervention was effective. A normal respiratory rate for an adult at rest is between 12 and 20 breaths per minute. A respiratory rate of 28/min is considered tachypnea, which could be a sign of respiratory distress, not an improvement.
Choice B rationale:
Pink mucous membranes are a good sign. They indicate effective oxygenation and perfusion. When the body is receiving an adequate amount of oxygen, the skin, lips, and mucous membranes can appear pink. This is a positive outcome of oxygen therapy for hypoxia.
Choice C rationale:
A heart rate of 110/min is not an indication that the intervention was effective. A normal resting heart rate for adults ranges from 60 to 100 beats per minute. A heart rate of 110/min is considered tachycardia, which could be a sign of distress or compensation for hypoxia, not an improvement.
Choice D rationale:
Restlessness is not an indication that the intervention was effective. On the contrary, restlessness can be a sign of inadequate oxygenation. When the brain does not receive enough oxygen, a patient can become restless or anxious. Therefore, restlessness is not a positive outcome of oxygen therapy for hypoxia.

Correct Answer is B
Explanation
Choice A rationale:
Positioning the client supine is not the immediate next step after performing hand hygiene when preparing to remove a patient’s urinary catheter. While it is important to ensure the patient is in a comfortable and appropriate position for the procedure, the immediate next step should be focused on ensuring the area is clean to prevent infection.
Choice B rationale:
After performing hand hygiene, the nurse should cleanse the perineal area with an antiseptic. This is to ensure that the area is clean before proceeding with the removal of the urinary catheter. It helps to prevent the introduction of bacteria into the urinary tract, which could lead to a urinary tract infection. The use of an antiseptic is recommended to kill any potential pathogens that may be present.
Choice C rationale:
Deflating the balloon halfway and then pulling out the catheter is not the immediate next step after performing hand hygiene. This step is usually done later in the process. Before deflating the balloon, it is important to ensure that the area is clean to prevent infection. Moreover, deflating the balloon halfway could potentially cause discomfort or injury to the patient. The balloon should be fully deflated before the catheter is removed.
Choice D rationale:
Having the client bear down during removal is not the immediate next step after performing hand hygiene. This action might be suggested during the actual removal of the catheter to aid in the process, but it is not the immediate next step. The focus right after hand hygiene should be on cleaning the area to prevent infection.
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.
