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 healthcare professional is assessing a client with left-sided heart failure. Which finding is most commonly associated with this condition?

• A. Peripheral edema
• B. Jugular vein distention
• C. Hepatomegaly
• D. Crackles in the lungs

Correct answer: D

Rationale: Crackles in the lungs are commonly associated with left-sided heart failure due to pulmonary congestion. Left-sided heart failure leads to the backup of blood into the lungs, causing fluid leakage into the alveoli, which results in the characteristic crackling sound upon auscultation.

3. A patient is receiving discharge instructions after experiencing a stroke. Which instruction is most important for preventing another stroke?

• A. Take prescribed antihypertensive medications regularly.
• B. Engage in physical therapy exercises.
• C. Follow a low-fat, low-cholesterol diet.
• D. Attend regular follow-up appointments with the healthcare provider.

Correct answer: A

Rationale: The correct answer is to take prescribed antihypertensive medications regularly. Hypertension is a major risk factor for stroke, and controlling blood pressure through medication is crucial in preventing recurrent strokes. While physical therapy, diet, and follow-up appointments are also important aspects of post-stroke care, managing hypertension with medication takes precedence due to its direct impact on stroke prevention.

4. During an assessment of the respiratory pattern of an older adult client receiving end-of-life care, which of the following assessment findings should the nurse identify as Cheyne-Stokes respirations?

• A. Breathing ranging from very deep to very shallow with periods of apnea
• B. Shallow to normal breaths alternating with periods of apnea
• C. Rapid respirations that are unusually deep and regular
• D. An inability to breathe without dyspnea unless sitting upright

Correct answer: A

Rationale: Cheyne-Stokes respirations are characterized by a pattern of breathing that ranges from very deep to very shallow with periods of apnea (temporary cessation of breathing). This pattern is often seen in clients near the end of life or with certain medical conditions affecting the respiratory control center in the brain. The alternating deep and shallow breaths can be distressing for both the client and caregivers. It is crucial for the nurse to recognize this pattern to provide appropriate care and support to the client and their family during this challenging time.

5. A client with cirrhosis is experiencing ascites. Which dietary instruction should the nurse provide?

• A. Increase protein intake.
• B. Limit fluid intake to 1500 mL/day.
• C. Consume a low-sodium diet.
• D. Take a daily multivitamin.

Correct answer: C

Rationale: For a client with cirrhosis experiencing ascites, the nurse should instruct them to consume a low-sodium diet. This dietary modification helps reduce fluid retention and manage ascites by decreasing the amount of sodium in the body, which helps prevent fluid accumulation in the abdomen. Limiting sodium intake is crucial in managing ascites and preventing further complications in clients with cirrhosis.
