1. A healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. Widened QRS complexes
• B. Hyperactive deep tendon reflexes
• C. Bounding peripheral pulses
• D. Warm, flushed skin

Correct answer: A

Rationale: Respiratory acidosis is a condition characterized by increased carbon dioxide levels in the blood, resulting in acidosis. One of the potential consequences of respiratory acidosis is the development of electrolyte imbalances, particularly hyperkalemia. Hyperkalemia can lead to cardiac conduction abnormalities, manifested as widened QRS complexes on an electrocardiogram (ECG). Therefore, in a client with respiratory acidosis, the healthcare professional should expect to find widened QRS complexes as a result of the associated hyperkalemia.

2. A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?

• A. I will breathe in quickly through my mouth and out through my nose.
• B. I will breathe in slowly through my nose and out through pursed lips.
• C. I will hold my breath for 10 seconds before exhaling.
• D. I will breathe in and out through pursed lips.

Correct answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.

3. A healthcare professional is assessing a client who has a new onset of confusion. Which laboratory value should the professional check first?

• A. Blood glucose level
• B. Serum sodium level
• C. Serum calcium level
• D. Blood urea nitrogen (BUN)

Correct answer: A

Rationale: In a client presenting with a new onset of confusion, checking the blood glucose level first is crucial as hypoglycemia can cause confusion and is easily correctable. Addressing hypoglycemia promptly is essential to prevent further complications.

4. A client in a clinic presents with an acute asthma exacerbation. Which of the following medications should reduce the symptoms?

• A. Cromolyn via a metered-dose inhaler
• B. Montelukast orally
• C. Budesonide via a dry-powder inhaler
• D. Albuterol via a jet nebulizer

Correct answer: D

Rationale: During an acute asthma exacerbation, the preferred medication for symptom relief is a short-acting beta-agonist like albuterol, typically delivered via a jet nebulizer for quick onset and efficacy. Cromolyn, montelukast, and budesonide are not as effective for immediate symptom relief in acute exacerbations and are more commonly used for prevention or long-term management of asthma symptoms.

5. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?

• A. 300 mL
• B. 480 mL
• C. 800 mL
• D. 950 mL

Correct answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.
