A NIH
CLIA
HHS
D. OSHA
The Correct Answer is B
A. NIH (National Institutes of Health): NIH conducts biomedical and public health research but does not regulate laboratory testing.
B. CLIA (Clinical Laboratory Improvement Amendments): This is correct. CLIA regulates laboratory testing and ensures quality standards in the clinical office setting.
C. HHS (Department of Health and Human Services): HHS oversees many health-related programs and agencies, but CLIA specifically regulates laboratory testing.

Correct Answer is B
Explanation
A. Place a pulse oximeter on the patient's earlobe: A pulse oximeter measures oxygen saturation and pulse but is not used for manually palpating the pulse.
B. Palpate the patient's radial artery: The radial artery, located at the wrist, is commonly palpated to manually obtain the pulse.
C. Place a pulse oximeter on the patient's finger: A pulse oximeter measures pulse rate and oxygen saturation but does not involve manual palpation.
D. Palpate the patient's popliteal artery: The popliteal artery is located behind the knee and is less commonly used for routine pulse measurement compared to the radial artery.
Correct Answer is D
Explanation
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.
