1. A patient with heart failure is prescribed furosemide (Lasix)
40 mg IV push. Which laboratory value requires the nurse to
notify the healthcare provider before administering the
medication?
A) Sodium 135 mEq/L
B) Potassium 2.9 mEq/L
C) Creatinine 0.9 mg/dL
D) Glucose 110 mg/dL
Answer: B
1
,*Rationale: Furosemide is a loop diuretic that causes potassium
wasting. A potassium level of 2.9 mEq/L is severely low (normal
3.5-5.0 mEq/L) and places the patient at risk for cardiac
arrhythmias. The nurse should hold the medication and notify the
provider for potassium replacement orders. Hyponatremia (A)
may occur with diuretics but 135 mEq/L is within normal range
(135-145 mEq/L). Creatinine 0.9 mg/dL (C) is normal (0.6-1.2
mg/dL). Glucose 110 mg/dL (D) is mildly elevated but not an
immediate contraindication.*
2. A patient is 2 days post-operative following a total knee
arthroplasty. Which finding is most concerning for a deep vein
thrombosis (DVT)?
A) Pain in the calf with dorsiflexion of the foot
B) Serous drainage from the surgical incision
2
,C) Temperature of 99.2°F (37.3°C)
D) Pain rated 4/10 at rest
Answer: A
Rationale: Calf pain with dorsiflexion of the foot (Homan's sign) is
a classic but non-specific finding associated with DVT. Other signs
include unilateral leg swelling, warmth, redness, and tenderness.
DVT is a serious complication requiring immediate intervention to
prevent pulmonary embolism. Serous drainage (B) is normal post-
operative. Low-grade fever (C) is common after surgery. Mild pain
at rest (D) is expected post-operatively.
3. A patient with chronic obstructive pulmonary disease
(COPD) has an oxygen saturation of 88% on room air. The
nurse applies supplemental oxygen at 2 L/min via nasal
cannula. Which assessment finding indicates the oxygen
therapy is effective?
3
, A) Respiratory rate decreases from 28 to 16 breaths per minute
B) Patient reports increased shortness of breath
C) Oxygen saturation decreases to 85%
D) Patient becomes lethargic and confused
Answer: A
*Rationale: Effective oxygen therapy improves oxygenation,
reducing the work of breathing. A decrease in respiratory rate
from 28 (tachypneic) to 16 (normal) indicates improved
oxygenation and reduced respiratory effort. Increased shortness
of breath (B) and decreased saturation (C) indicate worsening
condition. Lethargy and confusion (D) could indicate CO2
retention (hypoventilation), a risk with high-flow oxygen in COPD
patients, but 2 L/min is generally safe.*
4. A patient with diabetes mellitus type 2 is admitted with a
blood glucose level of 650 mg/dL. The patient is lethargic, has
