NUR 201 Exam 1 Review 2026 | Verified Q&A | Graded A+
1. If a patient presents with a blood pH of 7.28, what clinical condition might this
indicate, and what immediate action should be taken?
Alkalosis; the patient should be given sodium bicarbonate.
Normal pH; no action is needed.
Acidosis; the patient should be assessed for underlying causes and
treated accordingly.
Dehydration; the patient should be given fluids immediately.
2. Common causes of metabolic alkalosis include: 1. Renal failure. 2. Vomiting. 3.
Excessive sodium bicarbonate administration. 4. Gastric suctioning.

3. Describe how gastric bypass surgery can lead to nutritional deficiencies in
patients.
Gastric bypass surgery alters the digestive system, which can limit
nutrient absorption and lead to deficiencies.
Gastric bypass surgery improves the body's ability to absorb nutrients.
Gastric bypass surgery has no effect on nutrient absorption.
Gastric bypass surgery increases the stomach size, allowing for better
nutrient absorption.
,4. Describe the relationship between PaCO2 levels and acid-base balance in
the body.
Normal PaCO2 levels suggest that the body is in a state of metabolic
acidosis.
Decreased PaCO2 levels indicate metabolic alkalosis due to excessive
bicarbonate.
Increased PaCO2 levels indicate respiratory acidosis due to
hypoventilation, leading to an accumulation of carbon dioxide.
PaCO2 levels have no impact on acid-base balance.
5. Describe the significance of Trousseau's sign in relation to electrolyte
imbalances.
Trousseau's sign indicates hyperkalemia, characterized by muscle
weakness.
Trousseau's sign is related to acidosis, indicated by rapid breathing.
Trousseau's sign is a clinical indicator of hypocalcemia, where a
patient's hand spasms when a blood pressure cuff is inflated.
Trousseau's sign is a symptom of dehydration, showing dry skin.
6. What is the normal range of pH values for human blood?
6.8 to 7.2
7.0 to 7.3
7.5 to 7.8
7.35 to 7.45
, 7. A patient with severe asthma is experiencing respiratory acidosis. What
immediate intervention should the nurse prioritize?
Administer bronchodilators to improve airflow.
Initiate intravenous potassium replacement.
Increase the patient's fluid intake.
Provide a high-carbohydrate diet.
8. Describe how electrolyte imbalances can lead to digoxin toxicity.
Electrolyte imbalances have no effect on digoxin levels.
Electrolyte imbalances decrease the effectiveness of digoxin.
Electrolyte imbalances, particularly low potassium levels, can
increase the risk of digoxin toxicity by enhancing the drug's effects
on the heart.
Electrolyte imbalances only affect blood pressure, not digoxin
toxicity.
9. If a patient who has undergone gastric bypass surgery presents with
symptoms of fatigue and weakness, what should be the primary concern for
the healthcare provider?
Improved digestion
Infection at the surgical site
Increased body weight
Nutritional deficiency
10. Describe the significance of maintaining blood pH within the normal range.
Blood pH is only important during exercise.
