Correct Answer is C

Explanation

A. A fluid deficit may cause tachycardia and hypotension, but it does not directly cause diminished lung sounds.
B. Adventitious sounds (wheezes, crackles, rhonchi, etc.) are absent in this case. Diminished breath sounds suggest poor airflow, not abnormal sounds.
C. Hyperinflation of the lungs is correct. In conditions like chronic obstructive pulmonary disease (COPD) or emphysema, lung expansion is limited, leading to diminished breath sounds in all lung fields due to air trapping. The oxygen saturation of 92% is consistent with chronic lung disease.
D. Pectus carinatum (protrusion of the sternum) is a congenital deformity that does not cause diminished breath sounds.

A. In the left lower quadrant. B. At the symphysis pubis. C. In the right upper quadrant. D. Above the umbilicus.

Correct Answer is B

Explanation

A. The left lower quadrant contains portions of the small and large intestines but is not the starting point for palpating the bladder.
B. The nurse should begin palpating at the symphysis pubis because the bladder is located in the lower abdomen. When distended, it rises above the pubic symphysis and can extend toward the umbilicus.
C. The right upper quadrant contains the liver and gallbladder but is not relevant to bladder assessment.
D. A significantly distended bladder may extend above the umbilicus, but the nurse should begin palpation at the symphysis pubis and move upward to assess for distention.
