The nurse attaches a pulse oximeter to a client’s finger and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?
Capillary refill time is 2 seconds.
2+ edema of fingers and hands.
Radial pulse volume is 3+.
Blood pressure is 142/88 mm Hg.
The Correct Answer is B
Choice A rationale
Capillary refill time is 2 seconds. A capillary refill time of 2 seconds is within normal limits and is unlikely to affect the accuracy of the pulse oximetry reading.
Choice B rationale
2+ edema of fingers and hands. Edema can interfere with the accuracy of pulse oximetry readings by affecting the perfusion of the area where the sensor is placed. This can lead to falsely low oxygen saturation readings.
Choice C rationale
Radial pulse volume is 3+. A strong radial pulse indicates good peripheral perfusion, which should not negatively impact the accuracy of the pulse oximetry reading.
Choice D rationale
Blood pressure is 142/88 mm Hg. While elevated blood pressure can have various effects on the body, it is not likely to directly affect the accuracy of a pulse oximetry reading.

Correct Answer is D
Explanation
Choice A rationale
Sending an email to facility administrators reporting the action may not be the most immediate or effective way to address the situation. It could delay the necessary intervention and does not ensure that the issue is resolved promptly.
Choice B rationale
Warning the colleague that copying health information is unlawful is important, but it may not adequately address the potential breach of patient privacy and confidentiality. The colleague may already be aware of the laws but still engage in inappropriate behavior.
Choice C rationale
Disposing of the copies and continuing with client care assignments prevents further unauthorized access to patient information but does not address the issue of the colleague’s inappropriate handling of the records. It is essential to report the incident to the appropriate authority for further investigation and follow-up.
Choice D rationale
Communicating the colleague’s activities to the unit charge nurse is the most appropriate action because it informs the person in charge of the unit about the observed behavior, allowing for immediate intervention and potential corrective action. The unit charge nurse can address the situation promptly and ensure that patient privacy and confidentiality are maintained.
Correct Answer is A
Explanation
Choice A rationale
Smoking cessation is the most important lifestyle modification for preventing and managing cardiac disease. Smoking is a major modifiable risk factor that can cause atherosclerosis, hypertension, arrhythmias, thrombosis, and myocardial infarction. Quitting smoking has a more direct effect on improving the function and structure of the blood vessels and heart, significantly reducing the risk of cardiovascular events and mortality.
Choice B rationale
A low-fat diet is a useful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. While it helps in lowering cholesterol levels and reducing inflammation, smoking cessation has a stronger influence on overall cardiovascular health.
Choice C rationale
Stress reduction is a helpful lifestyle modification for preventing and managing cardiac disease, but it is not the most important one. Although managing stress can improve heart health, smoking cessation has a more immediate and significant impact on reducing cardiovascular risks.
Choice D rationale
Regular exercise is beneficial for preventing and managing cardiac disease, but it is not the most important lifestyle modification. Exercise helps in maintaining a healthy weight, lowering blood pressure, and improving overall cardiovascular health, but smoking cessation has a greater impact on reducing the risk of cardiovascular events.
