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 had an inferior wall myocardial infarction (MI). The nurse notes the client's cardiac rhythm as shown below. What action by the nurse is most important?

• A. Assess the client's blood pressure and level of consciousness.
• B. Call the health care provider or the Rapid Response Team.
• C. Obtain a permit for an emergency temporary pacemaker insertion.
• D. Prepare to administer antidysrhythmic medication.

Correct answer: A

Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.

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. 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.

5. A client with newly diagnosed osteoporosis is being taught about lifestyle modifications. Which instruction should be included?

• A. Increase intake of caffeinated beverages.
• B. Engage in weight-bearing exercises regularly.
• C. Avoid exposure to sunlight.
• D. Take calcium supplements with iron.

Correct answer: B

Rationale: Engaging in weight-bearing exercises is crucial for individuals with osteoporosis as it helps strengthen bones and reduce the risk of fractures. Weight-bearing exercises include activities like walking, jogging, dancing, and strength training. These exercises help improve bone density and overall bone health, making them an essential component of lifestyle modifications for individuals with osteoporosis.
