A nurse is teaching the guardian of a newborn about car seat safety.
Which of the following statements by the guardian indicates an understanding of the teaching?

Choice A rationale

A healthcare surrogate, or proxy, is a person designated by the patient themselves through a legal document called a durable power of attorney for healthcare. The provider's role is to provide medical care, not to make legal decisions for the patient. The patient retains the autonomy to choose who will make decisions for them when they are unable to do so. This is a fundamental principle of patient self-determination and legal rights.

Choice B rationale

A patient's competency can fluctuate. In situations of temporary incapacity, such as during a surgical procedure with anesthesia or a period of severe illness, a health care surrogate may make decisions. However, once the patient regains competency and is able to make informed decisions for themselves, they automatically resume control of their health care. This is a core tenet of patient autonomy and the purpose of advance directives.

Choice C rationale

A healthcare surrogate does not have to be a family member. The person designated by the patient can be a friend, a partner, or any trusted individual. The only requirement is that the surrogate is an adult who is willing and able to make healthcare decisions on the patient's behalf. It is a legal designation, not a familial one, that is based on the patient's trust and personal wishes.

Choice D rationale

A provider is legally and ethically obligated to follow a patient's wishes as outlined in their advance directives, as long as those wishes are within the bounds of standard medical practice and are not medically futile. To go against a patient's documented wishes would be a violation of patient autonomy and a breach of the legal protections afforded by advance directives.

Choice A rationale

Using clean technique for invasive procedures in a neutropenic client is insufficient. Neutropenia is a severe reduction in neutrophils, a key component of the immune system, leaving the client highly susceptible to infection. Aseptic or sterile technique, rather than clean technique, is necessary for all invasive procedures to prevent the introduction of pathogens. This includes strict hand hygiene, sterile gloves, and sterile fields to minimize infection risk.

Choice B rationale

Allowing healthy children to visit is a dangerous practice for a neutropenic client. Children, even those appearing healthy, can carry and transmit pathogens like viruses and bacteria that their developing immune systems can easily fight off. In a client with neutropenia, however, these common microorganisms can cause severe, life-threatening infections due to the lack of an adequate immune response. Therefore, visitors must be carefully screened.

Choice C rationale

Cleaning the client's room every 2 days is an inadequate frequency for a neutropenic client. An environment with reduced pathogen exposure is crucial for these immunocompromised clients. The room should be cleaned daily to minimize the accumulation of dust, dirt, and microorganisms. All surfaces, including floors, tables, and equipment, must be disinfected to reduce the risk of nosocomial infections and maintain a sterile environment.

Choice D rationale

Neutropenia impairs the body's ability to mount a fever response to infection. Therefore, a low-grade temperature elevation may be the only sign of a serious infection. Monitoring the client's temperature frequently, typically every 4 hours, is a critical nursing intervention. Early detection of a fever, even a slight one, allows for prompt initiation of antibiotics and other treatments, significantly improving the client's prognosis and preventing a potential septic shock. *.
