Extract:
Question 1 of 5
A client is to have hemodialysis. What must the nurse do before this treatment?
Correct Answer: C
Rationale: Pre-dialysis weight is crucial to determine fluid removal needs during dialysis.
Question 2 of 5
The nurse is reviewing the client's following arterial blood gases: pH 7.33, PaCo2 47, HCO3 24. Which manifestation would the nurse expect the client to be experiencing with this imbalance?
Correct Answer: A
Rationale: Respiratory acidosis (low pH, high PaCO2) causes confusion due to decreased brain oxygenation.
Question 3 of 5
The nurse is calculating the output of a client at the end of the shift. The nurse notes the following: the client voided 400 mL at 1100 and 350 at 1415. The chest tube was previously marked at 155 mL and is now 175 mL. The nasogastric tube has 575 mL in the drainage container and the Jackson Pratt drain had 25 mL emptied from it. How many ml's should the nurse record as output for the shift
Correct Answer: A
Rationale:
Total output is calculated as: Urine (400 mL + 350 mL = 750 mL) + Chest tube (175 mL - 155 mL = 20 mL) + Nasogastric tube (575 mL) + Jackson-Pratt drain (25 mL) = 1,370 mL.
Question 4 of 5
The nurse reviews the client's arterial blood gases and has the following results: pH 7.30. PaCO2 58, and HCO3 of 26. The nurse interprets these results that the client has which acid-base imbalance?
Correct Answer: D
Rationale: A low pH (<7.35) and high PaCO2 (>45 mmHg) indicate respiratory acidosis due to COâ‚‚ retention.
Question 5 of 5
What type of electrolyte imbalance would most likely occur following the administration of three tap water enemas?
Correct Answer: A
Rationale: Tap water enemas can cause potassium loss via stool and dilutional effects, leading to hypokalemia.
