A client with pneumonia has arterial blood gases levels at: pH 7.33; PaCO2 49 mm/Hg; HCO3 25 mEq/L; PaO2 95. What intervention should the nurse implement based on these results?

A. Institute coughing and deep breathing protocols.

B. Administer oxygen via nasal cannula.

C. Prepare for intubation and mechanical ventilation.

D. Increase IV fluids to improve hydration.

Correct Answer: A
Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

A client with type 1 diabetes is admitted with hypoglycemia. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer 15 grams of oral glucose
• C. Recheck the blood glucose level in 15 minutes
• D. Administer a glucagon injection

Correct Answer: A
Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.

A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct Answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of CAD and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify signs of ischemia or a heart attack. While other diagnostic tests like chest X-ray, arterial blood gases, and echocardiogram may also be necessary in the evaluation of chest pain, they do not provide the initial direct assessment of cardiac ischemia that an ECG does.

The nurse is preparing a community education program on osteoporosis. Which instruction is helpful in preventing bone loss and promoting bone formation?

• A. Recommend weight-bearing physical activity.
• B. Encourage a diet high in dairy products.
• C. Suggest vitamin D supplementation.
• D. Advise avoiding caffeine and alcohol.

Correct Answer: A
Rationale: The correct answer is A: Recommend weight-bearing physical activity. Weight-bearing exercises are effective in maintaining bone density and preventing osteoporosis by promoting bone formation. Encouraging a diet high in dairy products (choice B) can provide calcium, but it's not as directly related to bone formation as physical activity. While vitamin D supplementation (choice C) is important for calcium absorption and bone health, it is not directly involved in promoting bone formation. Advising to avoid caffeine and alcohol (choice D) can be beneficial for bone health, but it is not as directly related to promoting bone formation as weight-bearing physical activity.

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

• A. ‘I will reduce my salt intake to help manage my blood pressure.’
• B. ‘I will start exercising regularly to help control my blood pressure.’
• C. ‘I will avoid drinking alcohol to help manage my blood pressure.’
• D. ‘I will limit my caffeine intake to help control my blood pressure.’

Correct Answer: D
Rationale: The correct answer is D. Limiting caffeine intake is a positive lifestyle modification for managing hypertension. The statement indicates that the client understands the importance of reducing caffeine intake. Choices A, B, and C all reflect appropriate lifestyle modifications for managing hypertension, indicating good understanding by the client.
