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. What should be included in the therapeutic management of iron deficiency anemia?

• A. Multivitamins
• B. Calcium
• C. Ferrous sulfate
• D. Iodine

Correct answer: C

Rationale: The correct answer is C: Ferrous sulfate. The therapeutic management of iron deficiency anemia should include iron supplementation, specifically with ferrous sulfate. This helps to replenish the body's iron stores. Multivitamins (choice A) may contain iron, but iron supplementation is more direct and effective. Calcium (choice B) and iodine (choice D) are not typically part of the primary treatment for iron deficiency anemia.

3. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

4. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?

• A. Atherosclerotic plaque formation.
• B. Stasis of blood flow.
• C. Endothelial damage.
• D. Atherosclerotic vessel changes.

Correct answer: B

Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.

5. A male client with heart failure calls the clinic and reports that he cannot put his shoes on because they are too tight. Which additional information should the nurse obtain?

• A. What time he took his medication?
• B. Has his weight changed in the last several days?
• C. Is he still able to tighten his belt buckle?
• D. How many hours he slept last night?

Correct answer: B

Rationale: The correct answer is B: 'Has his weight changed in the last several days?' Sudden weight gain can indicate fluid retention, which is a common symptom of worsening heart failure. The inability to put on tight shoes can be due to fluid retention leading to swelling in the feet and ankles. Choices A, C, and D do not directly address the potential fluid retention issue and are less relevant in this scenario.
