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. What question should a nurse ask a client who has an anteroposterior (AP) chest diameter equal to the lateral chest diameter?

• A. Are you taking any medications or herbal supplements?
• B. Do you have any chronic breathing problems?
• C. How often do you perform aerobic exercise?
• D. What is your occupation and what are your hobbies?

Correct answer: B

Rationale: The correct answer is B. A nurse should ask the client if they have any chronic breathing problems when the anteroposterior (AP) chest diameter is the same as the lateral chest diameter. This finding indicates a barrel chest, which can be associated with chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) or emphysema. Assessing for chronic breathing problems can help the nurse further evaluate the client's respiratory status and provide appropriate care.

3. A nurse in the PACU is assessing a client who has an endotracheal tube (ET) in place and observes the absence of left-sided chest wall expansion upon respiration. Which of the following complications should the nurse suspect?

• A. Blockage of the ET tube by the client's tongue
• B. Passage of the ET tube into the esophagus
• C. Movement of the ET tube into the right main bronchus
• D. Infection of the vocal cords

Correct answer: C

Rationale: When the nurse observes the absence of left-sided chest wall expansion upon respiration, it indicates that the endotracheal tube (ET) may have migrated into the right main bronchus, leading to uneven chest expansion. This can result in inadequate ventilation to the left lung, causing respiratory compromise. The other options, such as blockage of the ET tube by the client's tongue, passage of the ET tube into the esophagus, and infection of the vocal cords, do not directly explain the observed chest wall asymmetry and respiratory distress.

4. A client just had a flexible bronchoscopy. Which of the following nursing actions is appropriate?

• A. Withhold food and liquids until the client's gag reflex returns.
• B. Irrigate the client's throat every 4 hours.
• C. Have the client refrain from talking for 24 hours.
• D. Suction the client's oropharynx frequently.

Correct answer: A

Rationale: After a flexible bronchoscopy, it is crucial to withhold food and liquids until the client's gag reflex returns to prevent aspiration. Irrigating the client's throat every 4 hours, having the client refrain from talking for 24 hours, and frequent suctioning of the oropharynx are not indicated post-bronchoscopy and may even pose risks to the client's recovery.

5. A nurse is caring for a client with a new diagnosis of type 1 diabetes. What is the most important aspect of teaching the nurse should focus on?

• A. The importance of regular exercise
• B. Proper administration of insulin
• C. Maintaining a low-carbohydrate diet
• D. Recognizing signs of hyperglycemia

Correct answer: B

Rationale: Proper administration of insulin is crucial for clients with type 1 diabetes as they are dependent on insulin for blood glucose control.
