PASS
1. A patient’s arterial blood gas (ABG) results are: pH 7.26, PaCO2 52 mmHg, and HCO3 24
mEq/L. How should the nurse interpret these findings?
A. Metabolic Acidosis
B. Metabolic Alkalosis
C. Respiratory Alkalosis
D. Respiratory Acidosis
Answer: D
Conceptual Explanation: The pH is low (acidosis), the PaCO2 is high (respiratory cause),
and the HCO3 is normal, indicating uncompensated respiratory acidosis.
2. Which assessment finding is most characteristic of a patient with hypocalcemia?
A. Hyperactive deep tendon reflexes
B. Positive Trousseau’s sign
C. Decreased bowel sounds
D. Shortened QT interval
,Answer: B
Conceptual Explanation: Positive Trousseau’s sign (carpal spasm induced by inflating a
blood pressure cuff) is a classic sign of neuromuscular irritability associated with
hypocalcemia.
3. The nurse is caring for a patient receiving a potassium-wasting diuretic. Which food choice
indicates the patient understands the necessary dietary modifications?
A. Cottage cheese
B. White bread
C. Apples
D. Baked potato
Answer: D
Conceptual Explanation: Potatoes are high in potassium, which is necessary to replace
losses from potassium-wasting diuretics.
4. A patient with a serum sodium level of 115 mEq/L is at highest risk for which complication?
A. Cardiac dysrhythmias
B. Tetany
C. Seizures
D. Constipation
Answer: C
, Conceptual Explanation: Severe hyponatremia (below 120 mEq/L) causes cerebral
edema, putting the patient at high risk for seizures and coma.
5. Which intravenous fluid is considered hypotonic?
A. 0.9% Normal Saline
B. Lactated Ringer’s
C. 0.45% Normal Saline
D. 5% Dextrose in 0.9% Saline
Answer: C
Conceptual Explanation: 0.45% Normal Saline (half-normal) is hypotonic, as its
osmolality is lower than that of plasma.
6. During the preoperative assessment, a patient reports a family history of high fever during
surgery. The nurse should alert the surgical team about the risk for:
A. Anaphylaxis
B. Sepsis
C. Hypovolemic shock
D. Malignant hyperthermia
Answer: D
