A Cardiovascular nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
Toe.
Earlobe.
Skin fold.
Finger.
The Correct Answer is B
Choice A rationale:
Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.
Choice B rationale:
The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.
Choice C rationale:
Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.
Choice D rationale:
While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.

Correct Answer is B
Explanation
Choice A rationale:
Reporting the incident to the charge nurse is important, but it's not the first action to take in this situation. The immediate concern should be addressing the potential exposure to bloodborne pathogens.
Choice B rationale:
This is the correct choice. Washing the area of the puncture thoroughly with soap and water is the first step the nurse should take after an accidental needlestick. It helps reduce the risk of infection by cleaning the wound and removing any potential contaminants.
Choice C rationale:
Going to employee health services is a valid step, but it's not the immediate action needed after an accidental needlestick. Cleaning the wound should come first.
Choice D rationale:
Completing an incident report is important for documentation purposes, but it is not the nurse's first priority in this situation. Immediate wound care takes precedence.
Correct Answer is D
Explanation
Choice A rationale:
Hypotension is not an expected manifestation of hypoxemia during an asthma attack. Hypotension refers to abnormally low blood pressure. During an asthma attack, the body's response to hypoxemia is more likely to involve increased heart rate (tachycardia) as the heart attempts to compensate for decreased oxygen levels.
Choice B rationale:
Dysphagia is not directly related to hypoxemia during an asthma attack. Dysphagia refers to difficulty swallowing, which is not a typical respiratory manifestation. Hypoxemia in asthma is more likely to lead to symptoms such as shortness of breath, wheezing, and increased work of breathing.
Choice C rationale:
Peripheral edema is not a typical manifestation of hypoxemia during an asthma attack. Peripheral edema, or swelling in the extremities, can occur in conditions like heart failure but is not directly related to the airway constriction and reduced oxygen exchange seen in asthma attacks.
Choice D rationale:
Agitation is the correct choice. Hypoxemia, which occurs when there is a decrease in the oxygen levels in the blood, can lead to inadequate oxygen supply to the brain. This can result in neurological symptoms such as agitation, restlessness, confusion, and even loss of consciousness. Agitation is a manifestation of the body's attempt to cope with the lack of oxygen.
