Left bundle branch

Purkinje fibers

Right bundle branch

Atrioventricular node

Answer and Explanation

The Correct Answer is D

A. Left bundle branch: The left bundle branch is stimulated after the atrioventricular node and bundle of His, not immediately after the sinoatrial node.
B. Purkinje fibers: The Purkinje fibers are stimulated later in the conduction pathway, after the bundle branches.
C. Right bundle branch: The right bundle branch is also stimulated after the atrioventricular node and bundle of His.
D. Atrioventricular node: After the sinoatrial node initiates the heartbeat, the electrical impulse travels to the atrioventricular node, which then passes the signal to the bundle of His and down to the bundle branches.

Correct Answer is C

Explanation

Correct answer: C
A. A steady pulse rhythm in a 16-year-old male patient. A steady pulse rhythm is normal and within the expected range for a 16-year-old male.
B. A pulse rate of 68/min in a 35-year-old female patient: A pulse rate of 68/min is within the normal resting heart rate range for a 35-year-old female (60-100/min).
C. A bounding pulse volume in a 56-year-old male patient: A bounding pulse volume indicates an unusually strong pulse, which could be a sign of hypertension or other circulatory issues and should be reported.
D. A pulse rate of 120/min in a 22-year-old female patient: A pulse rate of 120/min is above the normal range (tachycardia) and should be reported, as it could indicate a cardiac or systemic problem.

A. Ask the laboratory to send a link to an electronic version of the patient's report. B. Scan the report into the patient's electronic health record (EHR). C. Document that the results were delivered to the office in the patient's electronic health record (EHR). D. Sign their initials and place in the "to be filed" bin.

Correct Answer is B

Explanation

A. Ask the laboratory to send a link to an electronic version of the patient's report: The laboratory is not responsible for providing electronic versions of reports if paper reports are already received.
B. Scan the report into the patient's electronic health record (EHR): Scanning the report into the EHR ensures that the patient’s records are complete and accessible within the system.
C. Document that the results were delivered to the office in the patient's electronic health record (EHR): While documenting receipt is important, it does not substitute for the actual entry of the report into the EHR.
D. Sign their initials and place in the "to be filed" bin: Simply filing the report without scanning it into the EHR means the information is not integrated into the patient's digital health record.
