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:
This situation represents an example of assault. Assault is the threat of bodily harm or unwanted physical contact, which creates an apprehension of fear in the victim. In this case, the laboratory technician's actions of restraining the client's arm against their will for blood drawing without consent is a form of assault as it involves an intentional act causing fear of harm.
Choice B rationale:
While telling a client that the nurse "does not know anything" is unprofessional and disrespectful, it doesn't constitute assault. This scenario is more related to issues of communication and respect rather than a direct threat of physical harm.
Choice C rationale:
Restraining a client at bedtime to prevent wandering is not assault. This scenario might involve ethical considerations and the appropriate use of restraints, but it doesn't meet the legal definition of assault, which involves a threat of physical harm.
Choice D rationale:
Threatening to tie down a client if they try to get up from the chair is an example of assault. This action creates an apprehension of fear in the client by implying a physically harmful act. It's a direct threat that falls under the category of assault.
Correct Answer is D
Explanation
Choice A rationale:
The choice "Patient ate half of his breakfast tray" is not the correct answer. While poor appetite or decreased intake can impact a patient's nutritional status, it is not a direct indicator of pressure ulcer risk.
Choice B rationale:
The choice "Patient has a raised erythematous rash below the knee" is not the correct answer. This might indicate a localized skin issue, such as an allergic reaction or dermatitis, but it is not a clear sign of pressure ulcer risk.
Choice C rationale:
The choice "Patient has a capillary refill of less than 2 seconds" is not the correct answer. Capillary refill time assesses peripheral circulation and is useful in evaluating perfusion, but it is not specifically indicative of pressure ulcer risk.
Choice D rationale:
The correct answer is "Patient is incontinent of stool." Choice D is the correct answer. Incontinence, especially fecal incontinence, increases the risk of pressure ulcer development. Prolonged exposure to moisture from urine or stool weakens the skin's integrity, making it more susceptible to breakdown when pressure is applied over bony prominences.
