Hondros NUR 205 exam 3 ACTUAL EXAM
2026 TEST COMPREHENSIVE QUESTIONS
AND VERIFIED ANSWERS (DETAILED &
ELABORATED) 100% SOLVED 2026!
1. A patient with CHF has crackles, JVD, and 2+ pitting edema. What is the
nurse’s priority intervention?
A. Restrict oral fluids
B. Administer prescribed diuretic
C. Elevate legs
D. Encourage coughing and deep breathing
Correct Answer: B
Rationale: Diuretics reduce fluid overload and pulmonary congestion, improving oxygenation
and cardiac workload.
2. A potassium level of 2.9 mEq/L indicates:
A. Normal potassium
B. Hyperkalemia
C. Hypokalemia
D. Renal failure
Correct Answer: C
Rationale: Normal K⁺ is 3.5–5.0 mEq/L. Low potassium increases risk for dysrhythmias.
3. Which symptom is most concerning in hypokalemia?
A. Muscle cramps
B. Constipation
C. Weak pulse
D. Cardiac dysrhythmias
Correct Answer: D
Rationale: Low potassium can cause lethal arrhythmias.
,4. A patient on furosemide is at risk for which electrolyte imbalance?
A. Hypernatremia
B. Hypercalcemia
C. Hypokalemia
D. Hypermagnesemia
Correct Answer: C
Rationale: Loop diuretics cause potassium loss.
5. The nurse is teaching a patient with diabetes about hypoglycemia. Which is a
classic sign?
A. Fruity breath
B. Polyuria
C. Shakiness and sweating
D. Kussmaul respirations
Correct Answer: C
Rationale: Hypoglycemia causes adrenergic symptoms (sweating, tremors, palpitations).
6. A patient with blood glucose of 52 mg/dL who is alert should receive:
A. IV insulin
B. Orange juice
C. Glucagon IM
D. NPO status
Correct Answer: B
Rationale: Conscious hypoglycemia = give 15g fast-acting carbs orally.
7. Which lab value indicates dehydration?
A. Sodium 140
B. BUN 30
C. Potassium 4.0
D. Hemoglobin 13
, Correct Answer: B
Rationale: Elevated BUN suggests dehydration due to hemoconcentration.
8. A patient with COPD is prescribed oxygen. Which is the safest initial flow
rate?
A. 1–2 L/min
B. 6 L/min
C. 10 L/min
D. 15 L/min
Correct Answer: A
Rationale: COPD patients require low-flow oxygen to prevent respiratory depression.
9. The best position to improve oxygenation is:
A. Supine
B. Trendelenburg
C. High Fowler’s
D. Prone
Correct Answer: C
Rationale: Upright positioning maximizes lung expansion.
10. Which finding suggests fluid volume overload?
A. Dry mucous membranes
B. Bounding pulses
C. Poor skin turgor
D. Hypotension
Correct Answer: B
Rationale: Bounding pulses indicate increased circulating volume.
11. The priority action for a patient with chest pain and shortness of breath:
A. Obtain labs
B. Administer oxygen
