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 client has been diagnosed with hypertension but does not take the antihypertensive medications because of a lack of symptoms. What response by the nurse is best?

• A. Do you have trouble affording your medications?
• B. Most people with hypertension do not have symptoms.
• C. You are lucky; most people get severe morning headaches.
• D. You need to take your medicine or you will get kidney failure.

Correct answer: B

Rationale: Most people with hypertension are asymptomatic, although a small percentage do have symptoms such as headache. The nurse should explain this to the client. Asking about paying for medications is not related because the client has already admitted nonadherence. Threatening the client with possible complications will not increase compliance.

3. A client with dyspnea and difficulty climbing stairs is classified as having class III dyspnea. Which intervention should the nurse include in the client's plan of care?

• A. Assistance with activities of daily living.
• B. Daily physical therapy activities.
• C. Oxygen therapy at 2 liters per nasal cannula.
• D. Complete bedrest with frequent repositioning.

Correct answer: A

Rationale: Class III dyspnea indicates significant limitations in activity due to shortness of breath. Clients with this level of dyspnea should be encouraged to participate in activities within their tolerance levels. Providing assistance with activities of daily living helps conserve energy for essential tasks while promoting independence. Oxygen therapy is only necessary if hypoxia is present, and complete bedrest is generally not recommended for clients with dyspnea unless specifically indicated.

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 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.
