Pulmonary Embolism NCLEX Questions 1-5


Welcome to Pulmonary Embolism NCLEX Questions. Enjoy answering and I hope that NCLEX Review Classes can somehow help you in your future examination. 
Good Luck.

1. A client who is found unresponsive has arterial blood gases drawn and the results indicate the following: pH is 7.12, Pco 2 is 90 mm Hg, and is 22 mEq/L. The nurse interprets the results as indicating which condition?

a) Metabolic acidosis with compensation
b) Respiratory acidosis with compensation
c) Metabolic acidosis without compensation
d) Respiratory acidosis without compensation

2. The nurse notes that a client’s arterial blood gas results reveal a pH of 7.50 and a Pco 2 of 30 mm Hg. The nurse monitors the client for which clinical manifestations associated with these arterial blood gas results? Select all that apply.

a) Nausea
b) Confusion
c) Bradypnea
d) Tachycardia
e) Hyperkalemia
f) Lightheadedness

3. The nurse reviews the blood gas results of a client with atelectasis. The nurse analyzes the results and determines that the client is experiencing respiratory acidosis. Which result validates the nurse’s findings?

a) pH 7.25, Pco 2 50 mm Hg
b) pH 7.35, Pco 2 40 mm Hg
c) pH 7.50, Pco 2 52 mm Hg
d) pH 7.52, Pco 2 28 mm Hg

4. The nurse is caring for a client who is on a mechanical ventilator. Blood gas results indicate a pH of 7.50 and a Pco 2 of 30 mm Hg. The nurse has determined that the client is experiencing respiratory alkalosis. Which laboratory value would most likely be noted in this condition?

a) Sodium level of 145 mEq/L
b) Potassium level of 3.0 mEq/L
c) Magnesium level of 2.0 mg/dL
d) Phosphorus level of 4.0 mg/dL

5. The nurse plans care for a client with chronic obstructive pulmonary disease (COPD), understanding that the client is most likely to experience what type of acid-base imbalance?

a) Metabolic acidosis
b) Metabolic alkalosis
c) Respiratory acidosis
d) Respiratory alkalosis




Pulmonary Embolism NCLEX Questions
Answers and Rationale

 1) D
- The acid-base disturbance is respiratory acidosis without compensation. The normal pH is 7.35 to 7.45. The normal Pco 2 is 35 to 45 mm Hg. In respiratory acidosis the pH is decreased and the Pco 2 is elevated. The normal bicarbonate ( ) level is 22 to 27 mEq/L. Because the bicarbonate is still within normal limits, the kidneys have not had time to adjust for this acid-base disturbance. In addition, the pH is not within normal limits. Therefore the condition is without compensation. The remaining options are incorrect interpretations.

 2) A, B, D, F
- Respiratory alkalosis is defined as a deficit of carbonic acid or a decrease in hydrogen ion concentration that results from the accumulation of base or from a loss of acid without a comparable loss of base in the body fluids. This occurs in conditions that cause overstimulation of the respiratory system. Clinical manifestations of respiratory alkalosis include lethargy, lightheadedness, confusion, tachycardia, dysrhythmias related to hypokalemia, nausea, vomiting, epigastric pain, and numbness and tingling of the extremities. Hyperventilation (tachypnea) occurs.

 3) A 
- Atelectasis is a condition characterized by the collapse of alveoli, preventing the respiratory exchange of oxygen and carbon dioxide in a part of the lungs. The normal pH is 7.35 to 7.45. The normal Pco 2 is 35 to 45 mm Hg. In respiratory acidosis, the pH is decreased and the Pco 2 is elevated. Option B identifies normal values. Option C identifies an alkalotic condition, and option D identifies respiratory alkalosis.

4) B
- Respiratory alkalosis is defined as a deficit of carbonic acid or a decrease in hydrogen ion concentration that results from the accumulation of base or from a loss of acid without a comparable loss of base in the body fluids. This occurs in conditions that cause overstimulation of the respiratory system. Clinical manifestations of respiratory alkalosis include lethargy, lightheadedness, confusion, tachycardia, dysrhythmias related to hypokalemia, nausea, vomiting, epigastric pain, and numbness and tingling of the extremities. All three incorrect options identify normal laboratory values. The correct option identifies the presence of hypokalemia.

5) C
- Respiratory acidosis is most often caused by hypoventilation in a client with COPD. Other acid-base disturbances can occur in a client with COPD during exacerbation of the disease, but the most likely imbalance is respiratory acidosis. The remaining options are incorrect. COPD is a respiratory condition, not a metabolic one. Respiratory alkalosis is associated with hyperventilation.
