"A state of cleanliness that decreases the potential for the spread of infections"

A nurse is working within the managed care delivery model. Which of the following is true regarding managed care? A-All plans have the same values underlying the delivery of care. B-Their values are not reflected in the decision making. C-All systems reflect the values of efficiency and effectiveness. D-There are no conflicts between cost-effectiveness and respectful care.

*A-All systems in the managed care delivery model reflect the values of efficiency and effectiveness* Different plans may have different values underlying the delivery of care. However, they all reflect the business plan values of efficiency and effectiveness. Their values are reflected in the decision making and the policy development of the organization. Value conflicts between cost-effectiveness and respectful care may be seen.

Which measure is contraindicated when the nurse assists a child who has leukemia with oral hygiene? applying petroleum jelly to the lips cleaning the teeth with a toothbrush swabbing the mouth with moistened cotton swabs rinsing the mouth with a nonirritating mouthwash

*The oral mucous membranes are easily damaged and are commonly ulcerated in the client with leukemia. It is better to provide oral hygiene without using a toothbrush, which can easily damage sensitive oral mucosa.* Applying petroleum jelly to the lips, swabbing the mouth with moistened cotton swabs, and rinsing the mouth with a nonirritating mouthwash are appropriate oral care measures for a child with leukemia.

A nurse in the infection prevention and control program is conducting an assessment of infection control practices. The nurse is evaluating the infection control actions taken on the unit for a client with a decreased white blood cell count. Which of the following infection control practices does the nurse consider most important for this client? A-Diligent adherence to aseptic technique B-Using antimicrobial soap when providing care C-Requesting prophylactic antibiotic treatment D-Implementing respiratory isolation procedures

The client in this scenario is neutropenic, which places the client at risk for contracting an infection. All measures of aseptic technique must be used to protect the client. The other options do not provide complete protection for the client.
