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. Recurrent abdominal pain (RAP) is most often seen in school-age or adolescent children. The nurse should assess closely for what potential problem?

• A. Physical problems
• B. Relational problems
• C. Eating disorders
• D. Emotional problems

Correct answer: D

Rationale: The correct answer is D: 'Emotional problems.' Recurrent abdominal pain (RAP) in children is frequently associated with emotional factors rather than physical issues, relational problems, or eating disorders. Children may manifest emotional distress through physical symptoms like abdominal pain, making it crucial for nurses to assess for emotional problems as a potential cause.

3. The parents of a child who has had a myringotomy are instructed by the nurse to place the child in which position?

• A. Supine
• B. On the affected side
• C. On the unaffected side
• D. In Trendelenburg's position

Correct answer: B

Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.

4. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?

• A. Inflammation of the synovial membrane.
• B. Degeneration of the cartilage in the joint.
• C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
• D. Formation of uric acid crystals in the joint space.

Correct answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

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.
