The nurse is preparing a client with breast cancer for BRCA1 and BRCA2 genetic testing. Which pathophysiological process should the nurse use to support client teaching?

Choice A rationale

Monitoring the client’s white blood cell count is important in this case. An elevated white blood cell count is a common sign of infection, and regular monitoring can help assess the client’s response to treatment.
Choice B rationale
Implementing contact precautions for staff and visitors is crucial when caring for a client with a potential VRE infection. VRE is a multi-drug resistant organism that can be spread through direct contact, so strict infection control measures are necessary.
Choice C rationale
Using standard precautions and wearing a mask is generally good practice in healthcare settings to prevent the spread of infections. However, a mask is not specifically required for contact precautions with VRE456.
Choice D rationale
Explaining the purpose of a low bacteria diet is not relevant in this case. While diet can play a role in overall health and recovery, it is not a specific intervention for a client with a potential VRE infection.
Choice E rationale
Sending wound drainage for culture and sensitivity is an important step in confirming the presence of VRE and determining the most effective antibiotic therapy.

Choice A rationale
For a client who has been intubated and is on a ventilator due to sepsis, the most appropriate action based on the client’s status would be to continue weaning the ventilator as ordered.
Weaning is the process of gradually reducing ventilator support, and it is typically initiated once the underlying cause of respiratory failure has been addressed. In this case, if the client’s condition has stabilized and there are no contraindications, continuing the weaning process as ordered would be the most appropriate action.
Choice B rationale
Decreasing the tidal volume is not necessarily the most appropriate action based on the client’s status. Tidal volume is the amount of air that is inhaled or exhaled during normal breathing.
While adjustments to tidal volume may be necessary in some cases, such as if the client is experiencing discomfort or if there are concerns about lung injury, there is no information in the scenario to suggest that a decrease in tidal volume is required at this time.
Choice C rationale
Switching the ventilator to pressure control is not necessarily the most appropriate action based on the client’s status. Pressure control ventilation is a mode of ventilation that can be used in certain situations, such as when there is a need to limit airway pressures. However, there is no information in the scenario to suggest that this change is required at this time.
Choice D rationale

Increasing the fractional concentration of inspired oxygen is not necessarily the most appropriate action based on the client’s status. The fraction of inspired oxygen (FiO2) is the concentration of oxygen in the gas mixture that the client is breathing. While adjustments to FiO2 may be necessary in some cases, such as if the client’s oxygen levels are low, there is no information in the scenario to suggest that an increase in FiO2 is required at this time.
Choice E rationale
Increasing the respiratory rate is not necessarily the most appropriate action based on the client’s status. The respiratory rate is the number of breaths that the client takes per minute, and it can be adjusted on the ventilator to meet the client’s needs. However, there is no information in the scenario to suggest that an increase in the respiratory rate is required at this time.
Choice F rationale
Changing the ventilator settings to continuous positive airway pressure (CPAP) is not necessarily the most appropriate action based on the client’s status. CPAP is a mode of ventilation that can be used in certain situations, such as during the weaning process. However, there is no information in the scenario to suggest that this change is required at this time.
Choice G rationale
Alerting the provider of the blood gas values is not necessarily the most appropriate action based on the client’s status. While it is important to communicate significant changes or concerns to the provider, there is no information in the scenario to suggest that the blood gas values are abnormal or require immediate attention.
