A 65-year-old male patient with a history of hypertension and type 2 diabetes mellitus is admitted with acute decompensated heart failure (ADHF). His current vital signs are BP 160/95 mmHg, HR 110 bpm, RR 28 breaths/min, SpO2 88% on room air, and temperature 37.2°C. He is receiving supplemental oxygen via nasal cannula at 4 L/min. Laboratory results reveal a serum sodium of 132 mEq/L, potassium 4.0 mEq/L, BUN 45 mg/dL, and creatinine 1.8 mg/dL. The nurse anticipates initiating which of the following pharmacological interventions to address his pulmonary congestion and hypoxemia?

Intravenous nitroglycerin and positive pressure ventilation. The patient presents with signs and symptoms of ADHF, including hypertension, tachycardia, tachypnea, hypoxemia, and elevated BUN/creatinine, indicative of cardiorenal effects. Intravenous nitroglycerin is a potent vasodilator that reduces preload and afterload, alleviating pulmonary congestion. Positive pressure ventilation (e.g., BiPAP) is crucial for improving oxygenation and reducing the work of breathing in severe ADHF.

A nurse is caring for a patient who has undergone a total thyroidectomy. Postoperatively, the patient develops a positive Chvostek sign and a Trousseau sign. Which electrolyte imbalance is most likely responsible for these findings?

Hypocalcemia. Chvostek and Trousseau signs are classic indicators of neuromuscular irritability, which is a hallmark of hypocalcemia. During thyroidectomy, the parathyroid glands, which regulate calcium levels, can be inadvertently damaged or removed, leading to a drop in serum calcium.

A patient with a history of chronic obstructive pulmonary disease (COPD) is experiencing an exacerbation. The nurse assesses the patient and notes increased dyspnea, purulent sputum, and a temperature of 38.5°C. The patient's arterial blood gas (ABG) results are pH 7.32, PaCO2 55 mmHg, PaO2 60 mmHg, and HCO3- 30 mEq/L. Which interpretation of these ABGs is most accurate?

Respiratory acidosis with metabolic compensation. The ABG results show a low pH (7.32), indicating acidosis. The elevated PaCO2 (55 mmHg) suggests a respiratory origin for the acidosis. The elevated HCO3- (30 mEq/L) indicates metabolic compensation, as the kidneys are retaining bicarbonate to buffer the excess acid.

Study tips

Review the official exam content outline before your first practice run.
Take the full practice exam once to establish a baseline score by category.
Focus review on categories where you score below the passing threshold.
Re-take missed questions in drill mode until you can explain each correct answer.
Schedule the real exam only after consistent passing scores on practice tests.

Sample TEAS practice questions

Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.

Question 1Cardiovascular Nursing
A 65-year-old male patient with a history of hypertension and type 2 diabetes mellitus is admitted with acute decompensated heart failure (ADHF). His current vital signs are BP 160/95 mmHg, HR 110 bpm, RR 28 breaths/min, SpO2 88% on room air, and temperature 37.2°C. He is receiving supplemental oxygen via nasal cannula at 4 L/min. Laboratory results reveal a serum sodium of 132 mEq/L, potassium 4.0 mEq/L, BUN 45 mg/dL, and creatinine 1.8 mg/dL. The nurse anticipates initiating which of the following pharmacological interventions to address his pulmonary congestion and hypoxemia?
- A.Intravenous furosemide and a low-sodium diet
- B.Oral losartan and a low-carbohydrate diet
- C.Subcutaneous insulin and oral metformin
- D.Intravenous nitroglycerin and positive pressure ventilation(Correct)
Explanation
The patient presents with signs and symptoms of ADHF, including hypertension, tachycardia, tachypnea, hypoxemia, and elevated BUN/creatinine, indicative of cardiorenal effects. Intravenous nitroglycerin is a potent vasodilator that reduces preload and afterload, alleviating pulmonary congestion. Positive pressure ventilation (e.g., BiPAP) is crucial for improving oxygenation and reducing the work of breathing in severe ADHF.
Question 2Endocrine Nursing
A nurse is caring for a patient who has undergone a total thyroidectomy. Postoperatively, the patient develops a positive Chvostek sign and a Trousseau sign. Which electrolyte imbalance is most likely responsible for these findings?
- A.Hypocalcemia(Correct)
- B.Hyponatremia
- C.Hyperkalemia
- D.Hypercalcemia
Explanation
Chvostek and Trousseau signs are classic indicators of neuromuscular irritability, which is a hallmark of hypocalcemia. During thyroidectomy, the parathyroid glands, which regulate calcium levels, can be inadvertently damaged or removed, leading to a drop in serum calcium.
Question 3Respiratory Nursing
A patient with a history of chronic obstructive pulmonary disease (COPD) is experiencing an exacerbation. The nurse assesses the patient and notes increased dyspnea, purulent sputum, and a temperature of 38.5°C. The patient's arterial blood gas (ABG) results are pH 7.32, PaCO2 55 mmHg, PaO2 60 mmHg, and HCO3- 30 mEq/L. Which interpretation of these ABGs is most accurate?
- A.Respiratory alkalosis with metabolic compensation
- B.Respiratory acidosis with metabolic compensation(Correct)
- C.Metabolic acidosis with respiratory compensation
- D.Metabolic alkalosis with respiratory compensation
Explanation
The ABG results show a low pH (7.32), indicating acidosis. The elevated PaCO2 (55 mmHg) suggests a respiratory origin for the acidosis. The elevated HCO3- (30 mEq/L) indicates metabolic compensation, as the kidneys are retaining bicarbonate to buffer the excess acid.
