Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

2. The health care provider is treating a child with meningitis with a course of antibiotic therapy. When should the nurse expect the child to be out of isolation?

• A. When the course of antibiotics is complete
• B. When a negative CNS culture is obtained
• C. When the antibiotics have been initiated for 24 hours
• D. When the child has no symptoms of the disease

Correct answer: C

Rationale: The correct answer is C because a child with bacterial meningitis should be isolated for at least 24 hours until antibiotic therapy has been initiated. This period allows the antibiotics to start working against the infection, reducing the risk of spreading it to others. Choice A is incorrect because isolation is not solely based on completing the course of antibiotics; the initiation is crucial. Choice B is incorrect as waiting for a negative CNS culture may take longer and delay necessary precautions. Choice D is incorrect as symptom resolution does not guarantee the eradication of the infection and may still pose a risk of transmission.

3. Methotrexate is prescribed for a client with rheumatoid arthritis (RA) who is also taking aspirin. What is the best explanation for the nurse to provide as to why a second medication has been added?

• A. Methotrexate slows the disease progression while aspirin controls the symptoms.
• B. Methotrexate helps to reduce the side effects of aspirin.
• C. Methotrexate has fewer harmful side effects than aspirin.
• D. Methotrexate enhances the effect of aspirin.

Correct answer: A

Rationale: The correct answer is A. Methotrexate is a disease-modifying antirheumatic drug (DMARD) that slows the progression of rheumatoid arthritis (RA), while aspirin helps control symptoms such as pain and inflammation. Therefore, the combination of methotrexate and aspirin is beneficial in managing RA by addressing both disease progression and symptom control. Choices B, C, and D are incorrect because methotrexate is not added to reduce the side effects of aspirin, has different side effects compared to aspirin, and does not enhance the effect of aspirin.

4. The nurse empties the nasogastric suction collection canister of a client who had a bowel resection the previous day and notes that 1,000 mL of gastric secretions were collected in the last 4 hours. The nurse should assess the client for symptoms of which related problem?

• A. Respiratory acidosis.
• B. Metabolic alkalosis.
• C. Hypoglycemia.
• D. Hyperkalemia.

Correct answer: B

Rationale: The correct answer is B: Metabolic alkalosis. Loss of gastric secretions can lead to metabolic alkalosis due to the loss of hydrochloric acid. This can result in an increase in blood pH levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, not related to the loss of gastric secretions. Hypoglycemia (choice C) is a low blood sugar level and is not directly related to the loss of gastric secretions. Hyperkalemia (choice D) is an elevated potassium level in the blood and is not typically associated with the loss of gastric secretions.

5. A 55-year-old client with symptoms of osteoarthritis asks which form of exercise would be most beneficial. What is the best response by the nurse?

• A. Walking.
• B. Running.
• C. Swimming.
• D. Weight lifting.

Correct answer: C

Rationale: The correct answer is C: 'Swimming.' Swimming is a low-impact exercise that helps maintain joint mobility and reduce pain in clients with osteoarthritis. Unlike running or weight lifting, swimming is gentle on the joints, making it an ideal choice for individuals with osteoarthritis. Walking can be beneficial too, but swimming is often preferred due to its low-impact nature. Running and weight lifting may exacerbate joint pain and should be avoided by individuals with osteoarthritis.
