  1. Blood glucose.
  2. Serum potassium.
  3. Serum sodium.
  4. Arterial blood gas.

Question 2

The client complains of difficulty breathing. What will the nurse most likely assess in this client?

  3. Increased respiratory rate.
  4. Decreased respiratory depth.
  5. Decreased respiratory rate.

Answer to Question 1

Correct Answer: 4
Rationale 1: The blood glucose level is not used to determine a client's degree of effective gas exchange.
Rationale 2: The serum potassium level is not used to determine a client's degree of effective gas exchange.
Rationale 3: The serum sodium level is not used to determine a client's degree of effective gas exchange.
Rationale 4: Blood for partial pressures or blood gases are usually obtained from arterial blood.

Answer to Question 2

Correct Answer: 1,2,3,4
Rationale 1: Use of accessory muscles is an assessment finding associated with difficulty breathing.
Rationale 2: Increased respiratory depth is an assessment finding associated with difficulty breathing.
Rationale 3: Increased respiratory rate is an assessment finding associated with difficulty breathing.
Rationale 4: The depth of respirations can be deeper (tidal volume greater than 500 mL of air) or more shallow if partial obstruction is present in conditions such as asthma. Respiratory rate is generally increased.
Rationale 5: Respiratory rate is generally increased.
