When assessing tactile fremitus, increased tactile fremitus is expected under which condition?
asthma
emphysema
pneumothorax
acute bronchitis
pneumonia
The Correct Answer is E
A. In asthma, increased airway resistance can lead to decreased fremitus due to air trapping and poor conduction of vibrations.
B. Emphysema results in hyperinflated lungs, which typically decreases tactile fremitus because of increased air in the alveoli.
C. Pneumothorax involves air in the pleural space, leading to decreased tactile fremitus as well, since air does not conduct vibrations well.
D. Acute bronchitis can cause some changes in fremitus, but it typically does not significantly increase it.
E. Pneumonia causes consolidation of lung tissue, which increases tactile fremitus due to enhanced transmission of vibrations through solidified lung tissue.

Correct Answer is C
Explanation
A. The closure of the pulmonic and mitral valves corresponds to heart sound S1, not S2.
B. The tricuspid and mitral valves close with S1.
C. Heart sound S2 represents the closure of the aortic and pulmonic valves, signaling the end of systole and the beginning of diastole.
D. The mitral valve closes with S1, not S2.
E. The pulmonic and tricuspid valves do not correspond with S2.
Correct Answer is E
Explanation
A. Calling another nurse for help is unnecessary unless additional assistance is required after initial interventions.
B. Giving pain medication as ordered may address the chest pain but does not address the immediate need for oxygenation.
C. Calling the admitting healthcare provider can be done later if symptoms do not improve, but the immediate priority is to improve oxygenation.
D. Telling the client to remain calm may help reduce anxiety but does not address the low oxygen saturation.
E. Applying oxygen via nasal cannula as ordered is the priority action to improve the client’s oxygen saturation and alleviate hypoxemia, which could be contributing to their chest pain.
