Nursing Elites

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. The nurse is collecting data on a child recently diagnosed with glomerulonephritis. Which question to the mother should elicit data associated with the cause of this disease?

• A. ''Has your child had any nausea or diarrhea?''
• B. ''Have you noticed any rashes on your child?''
• C. ''Did your child recently complain of a sore throat?''
• D. ''Did your child sustain any injuries to the kidney area?''

Correct answer: C

Rationale: The correct answer is 'Did your child recently complain of a sore throat?' Group A beta-hemolytic streptococcal infection is a known cause of glomerulonephritis. In this condition, the child typically becomes ill with streptococcal infection of the upper respiratory tract, and then after 1 to 2 weeks, symptoms of acute poststreptococcal glomerulonephritis can develop. This question aims to gather crucial information related to a potential trigger for glomerulonephritis. Choices A, B, and D are incorrect because they do not pertain to a common cause or associated symptom of glomerulonephritis.

3. The patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving epoprostenol (Flolan). Which assessment information requires the most immediate action by the nurse?

• A. The oxygen saturation is 94%.
• B. The blood pressure is 98/56 mm Hg.
• C. The patient's central IV line is disconnected.
• D. The international normalized ratio (INR) is prolonged.

Correct answer: C

Rationale: The most immediate action required by the nurse is to address the disconnected central IV line delivering epoprostenol (Flolan). Epoprostenol has a short half-life of 6 minutes, necessitating immediate reconnection to prevent rapid clinical deterioration. While oxygen saturation, blood pressure, and INR are important parameters requiring monitoring and intervention, the priority lies in ensuring the continuous delivery of the critical medication to stabilize the patient's condition.

4. Which goal has the highest priority in the plan of care for a 26-year-old homeless patient admitted with viral hepatitis who has severe anorexia and fatigue?

• A. Increase activity level.
• B. Maintain adequate nutrition
• C. Establish a stable environment
• D. Identify sources of hepatitis exposure

Correct answer: B

Rationale: The highest priority outcome is to maintain adequate nutrition because it is essential for hepatocyte regeneration. In viral hepatitis, the liver is affected, and proper nutrition supports the liver's function and regeneration. While increasing activity level and establishing a stable environment are important, they are not as urgent as ensuring the patient receives proper nutrition. Identifying sources of hepatitis exposure can help prevent future infections, but in the acute phase, the immediate focus should be on providing adequate nutrition to support the patient's recovery.

5. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?

• A. The absence of special cells in the rectum caused the disease.
• B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
• C. The disease does not occur due to increased bowel motility leading to spasm and pain.
• D. The disease is not caused by the inability to tolerate sugar found in dairy products.

Correct answer: A

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.
