Recognize

After you gather assessment data, use critical thinking, your past clinical experience and your general knowledge to correctly interpret the meaning of the data and gain an understanding of the patient's clinical situation and care needs. This understanding enables you to determine your next steps.

Care

Implement appropriate care based on your understanding of the patient's condition. Proper care cannot be provided without effective assessment and accurate recognition of the patient's condition.

You use critical thinking when you

Obtain an initial impression. Determine a course of action. Anticipate roles and functions as part of a team based on the patient's presentation and condition. Consistently re-evaluate the situation for changes, interpret these changes and apply them to the patient's care and treatment. Modify your actions based on the changes you observe.

Data Manager

One team member is responsible for communicating and recording key data during the resuscitation effort (for example, data related to medication administration and interruptions to chest compressions).

Medication Administrator

One team member is responsible for establishing vascular access and administering medications.

AED/Defibrillator Operator

One team member is responsible for managing the AED or defibrillator and for establishing any other monitoring. This team member also relieves the team member who is performing compressions.

Airway manager and ventilator

One team member is responsible for managing the airway and providing ventilations. A trained respiratory therapist, if available, would fill this role.

Team Leader

One team member is responsible for prioritizing and directing the other team members' actions.

15 A 12-lead ECG reveals a tachyarrhythmia with narrow QRS complexes (< 0.12 second). You would classify this arrhythmia as ________.

SVT (use the three letters not the word)(

Team Member Responsibilities

Team members: Have the necessary knowledge and skills to perform their assigned role. Stay in their assigned role but assist others as needed, as long as they are able to maintain their own assigned responsibilities. Communicate effectively with the team leader if they: -Feel they are lacking any knowledge or skills to perform assigned roles. -Identify something that the team leader may have overlooked. -Recognize a dangerous situation or need for urgent action. Share information with other team members. Focus on achieving the goals. Ask pertinent questions and share pertinent observations. Participate in debriefing sessions. Crew

You need to obtain intraosseous (IO) access. Identify the preferred site.

The anterior proximal tibia is often used for IO access because it provides a flat surface with a relatively thin outer layer of bone, a large marrow cavity and easily identifiable landmarks to facilitate placement. The proximal humerus is also commonly used.

Respiratory baseline

The phase on the capnography waveform representing the beginning of exhalation. During this phase, "dead space" air (i.e., air in the airways from the bronchioles to the nasal cavity that does not contain carbon dioxide) is exhaled from the body.

Respiratory upstroke

The phase on the capnography waveform representing the exhalation of air containing carbon dioxide from the alveoli. epresenting air from the alveoli that contains carbon dioxide being exhaled from the body. For most patients, the respiratory upstroke should be nearly vertical.

True

Assess, Recognize and Care

a concept that describes the ongoing process of gathering data about the patient's condition, using that data to identify a problem and then intervening to address the problem. Because an acutely ill patient's condition can change rapidly (for better or for worse), you must continuously assess the patient, recognize what is happening with the patient and provide care accordingly.

compressions

8 Which findings may suggest that a patient is experiencing hemodynamic compromise as a result of a bradyarrhythmia? Select all correct options that apply. Hypotension Ischemic chest discomfort Signs of shock Changes in mental status Hypertension Acute heart failure

everything but hypetension

1 When providing transcutaneous pacing, the appearance of wide QRS complexes and tall, broad T waves after each pacing spike confirms that mechanical capture has been achieved.

false

Crew Resource Management

is a concept that helps to promote effective and efficient teamwork and reduce the likelihood of errors. Crew resource management emphasizes using all available resources (including people, equipment and procedures) to reduce the likelihood of human error and promote effective and efficient teamwork. Crew resource management also guides team members to communicate directly and effectively with the team leader about dangerous or time-critical decisions. When a problem arises, team members must get the attention of the team leader, state their concern, describe the problem as they see it and suggest a solution. The team leader then provides direction, enabling the team to work together to resolve the issue.

Assess

is the process of gathering the data that help you to determine what is happening with the patient. To ensure that the most pressing problems are addressed first, take a phased, systematic approach to assessment: perform a rapid assessment, a primary assessment and (when the patient's condition allows) a secondary assessment. In an emergency situation, assessment is ongoing.

middle (approx 3-4th inter-coastal space)
