The nurse percusses a client with COPD and expects to hear:

Tympany

Hyperresonance

Resonance

Dullness

Answer and Explanation

The Correct Answer is B

A.   Tympany is a high-pitched sound typically heard over a hollow organ such as the stomach.
B.   Hyperresonance is often heard in patients with COPD, as the lungs are hyperinflated, leading to an increased resonance when percussed.
C.   Resonance is normal and would be heard in healthy, air-filled lungs.
D.   Dullness would suggest a solid or fluid-filled area, which is not typical of COPD unless there is a complication like pleural effusion.

Correct Answer is B

Explanation

A. Assess the forearm and hand for infection would be relevant if the swollen lymph node were in the upper extremity, but the inguinal node would be more associated with a lower extremity infection.
B. Assess the lower extremities is the correct next step since the inguinal lymph nodes drain the lower body, including the legs and genital area.
C. Assess the dorsalis pedis pulses is not the next step, though it may be important if vascular concerns are suspected.
D. None of the above is incorrect because assessing the lower extremities is the next logical step.

A. Atrioventricular (AV) node B. Bundle branches C. Bundle of His D. Sinoatrial (SA) node

Correct Answer is D

Explanation

A. Atrioventricular (AV) node: The AV node conducts electrical signals from the atria to the ventricles, but it is not the pacemaker of the heart.
B. Bundle branches: The bundle branches transmit the electrical impulses to the ventricles but are not the primary pacemaker.
C. Bundle of His: The Bundle of His conducts electrical signals from the AV node to the bundle branches and ventricles but does not act as the pacemaker.
D. Sinoatrial (SA) node: The SA node, located in the right atrium, is the primary pacemaker of the heart, initiating electrical impulses that regulate heart rhythm.
