Assessment of a client reveals a distended abdomen with some bulging of the flanks. Which test would be most accurate in confirming nurse's suspicions?
Abdominal x-ray
Shifting dullness
Fluid wave
Ultrasound
The Correct Answer is D
A. Abdominal x-ray: While it can show gas or bowel obstructions, it is less effective for confirming fluid presence.
B. Shifting dullness: This physical exam technique can indicate fluid but is less accurate than ultrasound.
C. Fluid wave: This physical exam can help suggest the presence of fluid, but it is also less reliable than imaging studies.
D. Ultrasound: An ultrasound is the most accurate and non-invasive way to confirm the presence of fluid, such as ascites, in the abdomen. It provides detailed imaging and confirmation without invasive procedures.

Correct Answer is C
Explanation
A. 20: Incorrect, as it would imply a much higher dose.
B. 0.2: Incorrect, as this would be far too low.
C. 2: Phenytoin 0.2 g is equivalent to 200 mg (0.2 g x 1000 mg/g). Since each capsule is 100 mg, the nurse would need to administer 2 capsules (200 mg / 100 mg per capsule = 2).
D. 200: Incorrect, as 200 capsules would be an overdose.
Correct Answer is A
Explanation
A. At the symphysis pubis: When the bladder is distended, it typically extends upward from the symphysis pubis. Therefore, the nurse should start palpation here to assess for bladder distention.
B. In the left lower quadrant: This location would be used to assess for structures like the descending colon or potential masses, not the bladder.
C. At the umbilicus: The bladder does not typically reach the umbilical region unless it is severely distended, making this less effective as a starting point.
D. In the right lower quadrant: This area is primarily used to assess structures such as the appendix or ascending colon, not the bladder.
