1. A patient presents with a pH of 7.28, PaCO2 of 52 mmHg, and HCO3 of 24 mEq/L. Which
acid-base imbalance is occurring?
A. Metabolic Acidosis
B. Respiratory Acidosis
,C. Respiratory Alkalosis
D. Metabolic Alkalosis
Correct Answer: B
Expert Explanation: The pH is below 7.35, indicating acidosis, while the PaCO2 is elevated
above 45 mmHg, indicating a respiratory cause. The HCO3 is within the normal range,
suggesting that compensation has not yet occurred. This clinical picture is classic for acute
respiratory failure or hypoventilation.
2. A client has suffered partial-thickness burns to the entire left arm and the anterior trunk.
Using the Rule of Nines, what is the estimated percentage of Total Body Surface Area (TBSA)
burned?
A. 18%
B. 36%
C. 27%
D. 45%
Correct Answer: C
Expert Explanation: According to the Rule of Nines, the entire arm accounts for 9% and
the anterior trunk accounts for 18%. Adding these two regions together (9 + 18) results in
a total of 27% TBSA. Accurate calculation is vital for determining fluid resuscitation needs
via the Parkland formula.
, 3. The nurse is caring for a patient with increased intracranial pressure (ICP). Which of the
following is a component of Cushing’s Triad?
A. Widening pulse pressure
B. Hypotension
C. Tachycardia
D. Increased respiratory rate
Correct Answer: A
Expert Explanation: Cushing’s Triad consists of bradycardia, irregular respirations, and a
widening pulse pressure (systolic hypertension). It is a late sign of brainstem compression
and impending herniation. Recognizing these signs early allows the nurse to intervene
before irreversible damage occurs.
4. Which assessment finding would the nurse expect in a patient experiencing autonomic
dysreflexia following a spinal cord injury at T6?
A. Pounding headache and hypertension
B. Severe hypotension
C. Tachycardia and diaphoresis below the injury
D. Pale, cool skin above the level of injury
Correct Answer: A
