1. A patient presents with a pH of 7.28, PaCO2 of 55 mmHg, and HCO3 of 26 mEq/L. Which
acid-base imbalance is the patient experiencing?
A. Metabolic Acidosis
B. Respiratory Alkalosis
C. Metabolic Alkalosis
D. Respiratory Acidosis
Answer: D
Conceptual Explanation: A pH below 7.35 indicates acidosis. A PaCO2 above 45 mmHg
indicates a respiratory cause, and since the HCO3 is normal, it is uncompensated
respiratory acidosis.
2. A nurse is caring for a patient receiving Digoxin. Which of the following electrolyte
imbalances increases the risk of Digoxin toxicity?
A. Hypercalcemia
B. Hyponatremia
,C. Hypermagnesemia
D. Hypokalemia
Answer: D
Conceptual Explanation: Hypokalemia (low potassium) sensitizes the myocardium to
digoxin, significantly increasing the risk of toxicity even if digoxin levels are within the
therapeutic range.
3. Which clinical finding is most indicative of a tension pneumothorax?
A. Dullness on percussion of the affected side
B. Tracheal deviation toward the unaffected side
C. Increased breath sounds on the affected side
D. Tracheal deviation toward the affected side
Answer: B
Conceptual Explanation: In a tension pneumothorax, air pressure builds up in the pleural
space, shifting the mediastinum and causing the trachea to deviate away from the collapsed
lung.
4. A patient is prescribed Warfarin. Which lab value should the nurse monitor to evaluate the
effectiveness of this medication?
A. aPTT
B. INR
, C. Platelet count
D. Hemoglobin
Answer: B
Conceptual Explanation: International Normalized Ratio (INR) and Prothrombin Time
(PT) are used to monitor the anticoagulant effects of Warfarin. aPTT is used for Heparin.
5. When assessing a patient with suspected cholecystitis, the nurse asks the patient to take a
deep breath while palpating the right upper quadrant. The patient abruptly stops inhaling
due to pain. This is known as:
A. McBurney’s Sign
B. Grey Turner’s Sign
C. Murphy’s Sign
D. Cullen’s Sign
Answer: C
Conceptual Explanation: Murphy’s Sign is a classic indicator of gallbladder inflammation
(cholecystitis). McBurney’s is for appendicitis; Grey Turner’s and Cullen’s relate to
pancreatitis.
6. A patient with Chronic Obstructive Pulmonary Disease (COPD) is receiving oxygen. Why is it
critical to avoid high concentrations of oxygen in this patient?
A. High oxygen causes pulmonary edema
