1. A college health nurse interprets the peak expiratory flow rate for a student who has asthma and finds that the student is in the yellow zone of his asthma action plan. The nurse should not base her actions on which of the following information?

• A. The student should use his quick-relief inhaler.
• B. The student's asthma is not well controlled.
• C. The student's peak flow is 50% to 80% of his best peak flow.
• D. The student needs to go to the hospital

Correct answer: D

Rationale: In an asthma action plan, the yellow zone indicates caution and signals a need to monitor symptoms closely. When a student is in the yellow zone, the appropriate action is to follow the prescribed steps, which typically include using a quick-relief inhaler and closely monitoring peak flow. Going to the hospital is usually reserved for severe asthma exacerbations in the red zone. Therefore, the information that the student needs to go to the hospital is not typically appropriate when the student is in the yellow zone.

2. Which action best demonstrates respect for autonomy when working with a client?

• A. Asks if the client has questions before signing a consent form
• B. Provides the client with accurate information when questioned
• C. Honors the promises made to the client and family
• D. Ensures fair treatment of the client compared to others

Correct answer: A

Rationale: Respect for autonomy involves allowing individuals to make decisions about their care. By asking if the client has questions before signing a consent form, the nurse is respecting the client's right to make informed choices and decisions regarding their healthcare. This action supports the principle of self-determination and autonomy in healthcare decision-making.

3. 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.

4. A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?

• A. Do you have trouble breathing or chest pain?
• B. Are you able to walk upstairs without fatigue?
• C. Do you awake with breathlessness during the night?
• D. Do you have new-onset heaviness in your legs?

Correct answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

5. 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.
