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.

Answer and Explanation

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 D

Explanation

Choice A rationale:

Decreased heart rate is not an anticipated finding in response to acute pain. Pain typically triggers sympathetic nervous system activation, leading to an increased heart rate as a physiological response to the stressor.

Choice B rationale:

Hyperactive bowel sounds are not typically associated with acute pain. Acute pain is more likely to induce a sympathetic response, which can lead to decreased gastrointestinal motility and hypoactive bowel sounds.

Choice C rationale:

Decreased blood pressure is not a common response to acute pain. Pain often leads to an increase in blood pressure due to the activation of the sympathetic nervous system and the release of stress hormones.

Choice D rationale:

Increased respiratory rate is the anticipated finding in response to acute pain. Acute pain can cause an increase in the sympathetic nervous system activity, leading to a higher respiratory rate as the body prepares for a fight-or-flight response. This increased respiratory rate helps oxygenate the blood and meet the potential increased demand for energy during stress.

A. Veracity. B. Autonomy. C. Nonmaleficence. D. Fidelity.

Correct Answer is C

Explanation

Choice A rationale:

Veracity refers to truthfulness and honesty in communication between the healthcare provider and the client. It involves providing accurate information and not deceiving the client. Discontinuing the experimental medication due to kidney failure demonstrates a commitment to the truth, but the primary ethical principle demonstrated here is nonmaleficence.

Choice B rationale:

Autonomy refers to respecting the client's right to make their own decisions about their healthcare. In this scenario, the medication was discontinued due to evidence of harm to the client's health. This action prioritizes the client's well-being over their autonomy to continue the treatment.

Choice C rationale:

Nonmaleficence, or the principle of "do no harm," is demonstrated in this scenario. The experimental medication was discontinued because it was causing rapidly advancing kidney failure. The healthcare provider's decision to stop the treatment is an example of prioritizing the client's safety and well-being by preventing further harm.

Choice D rationale:

Fidelity refers to being loyal, keeping promises, and maintaining trust in the nurse-client relationship. While this principle is important, it doesn't directly apply to the situation described, where the focus is on the ethical responsibility to prevent harm.
