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.

Answer and Explanation

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.

A. Apply the client’s positive airway pressure device. B. Lift and lock the side rails in place. C. Remove dentures or other oral appliances. D. Elevate the head of the bed to a 45-degree angle.

Correct Answer is C

Explanation

Choice A rationale

Elevating the head of the bed to a 45-degree angle can help improve airway patency and reduce the risk of airway obstruction in clients with OSA. However, applying the positive airway pressure device (CPAP or BiPAP) takes precedence due to its direct impact on maintaining airway patency and preventing respiratory compromise.

Choice B rationale

Lifting and locking the side rails in place ensures the safety of the client but does not directly address the client’s OSA or the potential respiratory depression associated with opioid analgesic administration.

Choice C rationale

Applying the client’s positive airway pressure device is the most important intervention in this scenario. Clients with severe obstructive sleep apnea rely on positive airway pressure devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP), to maintain airway patency and prevent episodes of apnea during sleep. Applying the device before leaving the client alone ensures continuous support for effective breathing.

Choice D rationale

Removing dentures or other oral appliances may be necessary for client comfort and safety, but it is not directly related to managing OSA or preventing respiratory compromise associated with opioid analgesic administration.

A. Puts on new gloves when entering a client’s room. B. Uses sterile gloves when handling body fluids. C. Keeps a pair of gloves in uniform pocket. D. Dons sterile gloves when caring for clients with HIV.

Correct Answer is A

Explanation

Choice A rationale

Puts on new gloves when entering a client’s room. This action demonstrates an understanding of standard precautions, which are designed to reduce the risk of transmission of microorganisms from both recognized and unrecognized sources of infection. By putting on new gloves when entering a client’s room, the UAP is ensuring that they are not transferring any pathogens from one environment to another, thereby protecting both themselves and the client.

Choice B rationale

Uses sterile gloves when handling body fluids. While it is important to use gloves when handling body fluids, sterile gloves are not necessary unless performing a sterile procedure. Standard gloves are sufficient for most tasks involving body fluids, and the use of sterile gloves in these situations would be an unnecessary use of resources.

Choice C rationale

Keeps a pair of gloves in uniform pocket. This practice is not recommended as it can lead to contamination of the gloves. Gloves should be stored in a clean, dry place and should be taken from the box immediately before use. Keeping gloves in a pocket can expose them to contaminants, which can then be transferred to the client.

Choice D rationale

Dons sterile gloves when caring for clients with HIV. HIV is not transmitted through casual contact, and standard gloves are sufficient for routine care of clients with HIV. Sterile gloves are only necessary for sterile procedures, regardless of the client’s HIV status.
