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. How does the pain of a myocardial infarction (MI) differ from stable angina?

• A. Accompanied by shortness of breath
• B. Feelings of fear or anxiety
• C. Lasts about 3-5 minutes
• D. Relieved by taking nitroglycerin

Correct answer: A

Rationale: The pain of an MI is often accompanied by shortness of breath and feelings of fear or anxiety. It typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Unlike stable angina, the pain of an MI occurs without a known cause such as exertion.

3. 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.

4. A client is unconscious with a breathing pattern characterized by alternating periods of hyperventilation and apnea. The nurse should document that the client has which of the following respiratory alterations?

• A. Kussmaul respirations
• B. Apneustic respirations
• C. Cheyne-Stokes respirations
• D. Stridor

Correct answer: C

Rationale: Cheyne-Stokes respirations are characterized by periods of deep, rapid breathing followed by periods of apnea. This pattern is often seen in clients with neurological or cardiac conditions. Kussmaul respirations are deep and rapid breaths often associated with metabolic acidosis. Apneustic respirations are characterized by prolonged inhalations with shortened exhalations and can indicate damage to the pons. Stridor is a high-pitched, noisy respiratory sound usually associated with upper airway obstruction. Therefore, in this scenario, the client's alternating pattern of hyperventilation and apnea aligns with Cheyne-Stokes respirations.

5. A nurse is interested in providing community education and screening on hypertension. In order to reach a priority population, to what target audience should the nurse provide this service?

• A. African American churches
• B. Asian American groceries
• C. High school sports camps
• D. Women's health clinics

Correct answer: A

Rationale: The correct answer is African American churches. African Americans in the United States have one of the highest rates of hypertension globally. By providing services at African American churches, the nurse can effectively reach this priority population. While hypertension education and screening are essential for all groups, African Americans are the priority population for this intervention due to their disproportionately high rates of hypertension.
