1. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

2. A child has just been diagnosed with juvenile idiopathic arthritis. Which of the following statements about the disease is most accurate?

• A. The child has a poor chance of recovery without joint deformity.
• B. Most children progress to adult rheumatoid arthritis.
• C. Nonsteroidal anti-inflammatory drugs are the first choice in treatment.
• D. Physical activity should be minimized.

Correct answer: C

Rationale: The correct answer is that nonsteroidal anti-inflammatory drugs are the first choice in treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs are important as a first-line treatment and typically require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Choice A is incorrect as early treatment can improve outcomes and prevent joint deformities. Choice B is incorrect as juvenile idiopathic arthritis does not necessarily progress to adult rheumatoid arthritis. Choice D is incorrect as physical activity should be encouraged in children with arthritis to maintain joint mobility and overall health.

3. A nurse is caring for a patient with peripheral vascular disease (PVD). The patient complains of burning and tingling of the hands and feet and cannot tolerate touch of any kind. Which of the following is the most likely explanation for these symptoms?

• A. Inadequate tissue perfusion leading to nerve damage.
• B. Fluid overload leading to compression of nerve tissue.
• C. Sensation distortion due to psychiatric disturbance.
• D. Inflammation of the skin on the hands and feet.

Correct answer: A

Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest pain often is exacerbated by poor cardiac output. The condition is often partially or fully relieved by placing the extremity in a dependent position, so that perfusion is enhanced by the effects of gravity.

4. Your patient has shown the following signs and symptoms: Feeling very thirsty, large amount of water intake, dryness of the mouth, and urinary frequency. What physical disorder does this patient most likely have?

• A. Diabetes
• B. Angina
• C. Hypertension
• D. Hypotension

Correct answer: A

Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.

5. The nurse is caring for a newborn infant after surgical intervention for imperforate anus. The nurse should place the infant in which position in the postoperative period?

• A. Supine with no head elevation
• B. Side-lying with the legs flexed
• C. Side-lying with the legs extended
• D. Supine with the head elevated 30 degrees

Correct answer: B

Rationale: After surgical intervention for imperforate anus, the infant should be placed in a side-lying position with the legs flexed. This position helps reduce edema and pressure on the surgical site, preventing strain and promoting comfort. Placing the infant supine with no head elevation (Choice A) doesn't offer adequate support and may increase pressure on the area. Side-lying with the legs extended (Choice C) doesn't help reduce edema and pressure effectively. Placing the infant supine with the head elevated 30 degrees (Choice D) isn't recommended as it may not provide adequate support and comfort needed for recovery.
