Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A healthcare professional is preparing to administer albuterol syrup 1.6 mg PO tid. Available is albuterol 2 mg/5mL. How many mL should the healthcare professional administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 4 mL
• B. 6 mL
• C. 10 mL
• D. 5.5 mL

Correct answer: A

Rationale: To calculate the mL of albuterol syrup needed per dose, first, determine how many milligrams are in the prescribed dose: 1.6 mg. Next, set up a proportion to find the equivalent mL for 1.6 mg using the given concentration of 2 mg/5mL. The calculation is: (1.6 mg x 5 mL) / 2 mg = 4 mL. Therefore, the correct answer is 4 mL to administer per dose.

3. A nurse is assessing a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

• A. Pigeon
• B. Funnel
• C. Kyphotic
• D. Barrel

Correct answer: D

Rationale:

4. What instruction should be included when teaching a client with asthma about using a metered-dose inhaler (MDI)?

• A. Shake the inhaler well before use.
• B. Inhale rapidly while administering the medication.
• C. Administer the medication while lying down.
• D. Hold the inhaler 2 inches away from the mouth while inhaling.

Correct answer: A

Rationale: Shaking the inhaler well before use ensures that the medication is properly mixed, allowing for an accurate dose with each administration. Inhaling slowly and deeply, not rapidly, helps the medication reach the lungs effectively. The medication should be administered while sitting or standing to facilitate proper lung expansion and airflow. Holding the inhaler 2 inches away from the mouth can lead to medication loss; it should be placed directly in the mouth or used with a spacer to optimize delivery to the airways.

5. A nurse collaborates with a respiratory therapist to complete pulmonary function tests (PFTs) for a client. Which statements should the nurse include in communications with the respiratory therapist prior to the tests? (Select all that apply)

• A. I held the client's morning bronchodilator medication.
• B. The client is ready to go down to radiology for this examination.
• C. Physical therapy states the client can run on a treadmill.
• D. I advised the client not to smoke for 6 hours prior to the test.

Correct answer: B

Rationale: Communication between the nurse and respiratory therapist is crucial before pulmonary function tests (PFTs). It is important to inform the respiratory therapist that the client is ready for the examination. The nurse should not administer bronchodilator medication before the test as it may affect the results, and the client should not smoke for 6 to 8 hours prior to the test to ensure accurate results. Additionally, PFTs do not involve running on a treadmill; instead, the client may be required to perform specific breathing maneuvers as instructed by the respiratory therapist.
