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 A
Explanation
Choice A rationale:
The nurse is demonstrating the phase of nursing care known as "Implementation." During this phase, the nurse carries out the interventions and actions that were planned in the previous stages of the nursing process. In this scenario, applying warm compresses to the client's joint is a planned intervention that is being executed by the nurse.
Choice B rationale:
Planning is not the correct choice for this scenario. Planning is the phase of nursing care where the nurse sets goals, outcomes, and develops a plan of action based on the assessment data. It occurs before the implementation phase.
Choice C rationale:
Evaluation is not the correct choice for this scenario. Evaluation is the phase where the nurse assesses the outcomes of the interventions and determines whether the goals have been met. It comes after the implementation phase.
Choice D rationale:
Assessment is not the correct choice for this scenario. Assessment is the initial phase of the nursing process where the nurse collects data about the client's health status. It precedes the planning, implementation, and evaluation phases.
Correct Answer is B
Explanation
The correct answer is choice B. Increased anteroposterior diameter of the chest.
Choice A rationale:
Petechiae on the chest (Choice A) are tiny red or purple spots that appear on the skin due to small blood vessel breakage. They are not typically associated with COPD and emphysema. Petechiae are more often related to conditions like thrombocytopenia or certain infections, where blood clotting is impaired.
Choice B rationale:
Increased anteroposterior diameter of the chest, often referred to as "barrel chest," is a characteristic finding in clients with COPD and emphysema. This occurs due to the hyperinflation of the lungs and the loss of elasticity in the lung tissues, which causes the chest to become rounded and the ribs to be positioned more horizontally.
Choice C rationale:
An oxygen saturation level of 96% (Choice C) is within the normal range for oxygen saturation. However, while it's important for clients with COPD to maintain adequate oxygen levels, this value doesn't specifically correlate with the client's symptoms of a wet cough and occasional shortness of breath.
Choice D rationale:
Respiratory alkalosis (Choice D) involves an increase in blood pH due to decreased levels of carbon dioxide (hypocapnia) caused by hyperventilation. While respiratory alkalosis can occur in clients with COPD due to compensatory hyperventilation, it is not a direct assessment finding related to the client's symptoms of a wet cough and occasional shortness of breath.
