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 with hypertension is being taught about lifestyle modifications. Which statement by the client indicates a need for further teaching?

• A. I will reduce my sodium intake to help control my blood pressure.
• B. I need to start walking at least 30 minutes most days of the week.
• C. I can continue drinking alcohol as long as it is not in excess.
• D. I will check my blood pressure regularly at home.

Correct answer: C

Rationale: In hypertension management, it is crucial for clients to limit or avoid alcohol consumption, not just refrain from excess. Alcohol can raise blood pressure and interfere with the effectiveness of antihypertensive medications, making it a key lifestyle modification for individuals with hypertension.

3. After auscultating a client's breath sounds, the nurse is providing care. Which finding is correctly matched to the nurse's primary intervention?

• A. Hollow sounds are heard over the trachea. The nurse increases the oxygen flow rate.
• B. Crackles are heard in bases. The nurse encourages the client to cough forcefully.
• C. Wheezes are heard in central areas. The nurse administers an inhaled bronchodilator.
• D. Vesicular sounds are heard over the periphery. The nurse has the client breathe deeply.

Correct answer: C

Rationale: Wheezes are indicative of narrowed airways, and bronchodilators help to open the air passages, making option C the correct match. Wheezes are typically heard in the central or peripheral lung areas and are associated with conditions like asthma or COPD. Inhaled bronchodilators work by dilating the bronchioles, which helps alleviate wheezing and improve airflow. Therefore, administering an inhaled bronchodilator is the appropriate intervention in response to wheezes.

4. A client with asthma is assessed by a nurse and presents with bilateral wheezing, decreased pulse oxygen saturation, and suprasternal retraction on inhalation. Which actions should the nurse take? (Select all that apply)

• A. Administer prescribed albuterol (Ventolin) inhaler.
• B. Assess the client for tracheal deviation.
• C. Administer oxygen to maintain saturations greater than 94%.
• D. Perform peak expiratory flow measurements.

Correct answer: C

Rationale: Suprasternal retraction during inhalation indicates the use of accessory muscles and difficulty in moving air due to airway narrowing, supported by bilateral wheezing and decreased pulse oxygen saturation. This client needs immediate intervention as their asthma is not responding to the medication. Administering oxygen to maintain saturations above 94% is crucial to ensure adequate oxygenation. While administering a rescue inhaler could also be necessary, oxygen therapy takes priority in this situation.

5. A client has a newly inserted chest drainage system with a water seal. Which of the following actions should be taken?

• A. Clamp the tube when the client is ambulating.
• B. Keep the collection device below the level of the client's chest.
• C. Carefully coil the tubes to prevent kinking.
• D. Position the client flat to avoid leaks in the tubing.

Correct answer: B

Rationale: Keeping the collection device below the level of the client's chest ensures proper drainage and prevents backflow of fluid into the patient's chest. This position allows gravity to assist in the drainage process. Clamping the tube when the client is ambulating can cause a buildup of pressure in the chest drainage system, potentially leading to complications. Carefully coiling the tubes is important to prevent obstructions and kinks that could impede the flow of drainage. Positioning the client flat may not be ideal as it could hinder proper drainage and increase the risk of leaks in the tubing.
