The nurse is percussing the lungs of a patient.
The nurse knows that percussion over normal adult lungs will reveal:
Dullness.
Tympany.
Resonance.
Hyperresonance.
The Correct Answer is C
Choice A rationale
Dullness upon percussion indicates increased tissue density, such as in consolidation (e.g., pneumonia), pleural effusion, or a tumor. This occurs because the sound waves are attenuated and dampened by the solid or fluid-filled structures, resulting in a short, high-pitched, thudding sound.
Choice B rationale
Tympany is a drum-like, high-pitched, loud sound typically heard over air-filled organs like the stomach or intestines. When percussing the lungs, tympany suggests a large pneumothorax or a distended abdomen impinging on the thoracic cavity, indicating abnormal air accumulation.
Choice C rationale
Resonance is the expected percussive sound over healthy, air-filled lung tissue. It is a low-pitched, clear, hollow sound produced by the vibration of air within the alveoli and bronchi. This sound indicates normal lung aeration and the absence of significant pathology.
Choice D rationale
Hyperresonance is a louder, lower-pitched sound than normal resonance and suggests an increased amount of air in the lung or pleural cavity, such as in emphysema or pneumothorax. This hyperinflation causes greater vibration and a more boomy quality to the sound.

Correct Answer is ["25"]
Explanation
Step 1 is to determine the total infusion time in minutes. 1 L = 1000 mL. 1000 mL ÷ (150 mL/h) = 6.666. hours. 6.666. hours × (60 min/hour) = 400 minutes.
Step 2 is to calculate the flow rate in drops per minute. (1000 mL ÷ 400 min) × (10 gtts/mL) = 25 gtts/min. The flow rate is 25 gtts/min.
Correct Answer is ["1.1"]
Explanation
Step 1 is: 4500 units ÷ (4000 units/mL) = 1.125 mL.
Step 2 is: Rounding to the tenths place, the final calculated answer is 1.1 mL.
