Correct Answer: B

Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.

Correct Answer: B

Rationale: The correct answer is the patient with possible lung cancer who has just returned after bronchoscopy. After bronchoscopy, the patient may have decreased cough and gag reflexes, necessitating immediate assessment for airway patency to prevent potential complications. The other patients do not exhibit urgent clinical manifestations or have undergone recent procedures that require immediate attention. Therefore, they can be assessed after ensuring the safety and stability of the patient who has just returned after bronchoscopy.

Correct Answer: B

Rationale: A musical or drum-like sound (tympany) is heard when percussion occurs over an air-filled viscus, such as the stomach or intestines. This indicates the presence of air-filled areas. Constipation, choice A, does not produce specific percussion sounds and is related to bowel movements rather than the sound produced during percussion. The presence of a tumor, choice C, would not typically produce a drum-like sound but might result in dullness or decreased resonance. Dense organs, choice D, would produce a dull thud sound rather than a drum-like tympanic sound.

Correct Answer: D

Rationale: The correct action for the nurse to intervene in is when the UAP lowers the head of the patient's bed to 15 degrees. This position can decrease ventilation in a patient with pneumonia, potentially worsening their condition. Choices B and C involve assisting the patient with activities of daily living and promoting mobility, which are appropriate for the patient's care. Choice A, splinting the patient's chest during coughing, can help the patient manage coughing effectively, which is also appropriate for a patient with pneumonia.

Correct Answer: C

Rationale: When the infant is quiet or sleeping, it is an ideal time to assess the cardiac, respiratory, and abdominal systems. It is recommended not to wake the infant unnecessarily. Auscultating the lungs and heart while the infant is still sleeping allows for a comprehensive assessment without disturbing the infant. Examining the infant's hips prematurely may disrupt the infant's sleep. Starting with an assessment of the eye is not appropriate as it is an invasive procedure and should be performed towards the end of the examination after the non-invasive assessments have been completed.
