ANSWERS (CHAMBERLAIN) 100%
GUARANTEE PASS
1. A client presents with a pH of 7.28, PaCO2 of 52 mmHg, and HCO3 of 25 mEq/L. Which acid-
base imbalance is occurring?
A. Metabolic Acidosis
B. Respiratory Alkalosis
C. Respiratory Acidosis
D. Metabolic Alkalosis
Answer: C
Conceptual Explanation: A pH below 7.35 indicates acidosis. A PaCO2 above 45 mmHg
indicates a respiratory cause. The normal HCO3 suggests no compensation yet, confirming
respiratory acidosis.
2. Which of the following findings is the most early and sensitive indicator of increasing
intracranial pressure (ICP)?
A. Widening pulse pressure
B. Change in Level of Consciousness (LOC)
,C. Fixed and dilated pupils
D. Projectile vomiting
Answer: B
Conceptual Explanation: Changes in LOC, such as restlessness or agitation, are the earliest
signs of increased ICP. Other options like Cushing’s triad are late signs.
3. A nurse is caring for a patient with a potassium level of 6.2 mEq/L. Which ECG change
should the nurse expect?
A. Prominent U waves
B. ST-segment depression
C. Tall, peaked T waves
D. Prolonged QT interval
Answer: C
Conceptual Explanation: Hyperkalemia (K+ > 5.0) causes tall, peaked T waves.
Hypokalemia causes U waves and ST depression.
4. The nurse is preparing to administer Digoxin to a client. Which assessment finding would
require the nurse to hold the medication?
A. Blood pressure of 140/90 mmHg
B. Respiratory rate of 20 breaths per minute
C. Apical pulse of 52 beats per minute
, D. Potassium level of 4.5 mEq/L
Answer: C
Conceptual Explanation: Digoxin should be held if the apical pulse is less than 60 bpm in
adults to prevent further bradycardia.
5. When performing suctioning on a client with a tracheostomy, what is the maximum time
the nurse should apply suction?
A. 10-15 seconds
B. 5 seconds
C. 20-30 seconds
D. 1 minute
Answer: A
Conceptual Explanation: Suctioning should be limited to 10-15 seconds to prevent
hypoxia and mucosal damage.
6. A client is receiving a blood transfusion and reports chills and back pain. What is the
nurse’s priority action?
A. Slow the infusion rate
B. Notify the physician immediately
C. Stop the infusion
D. Check the patient’s temperature
