Nursing Elites

1. Which laboratory data indicate the client’s pancreatitis is improving?

• A. The amylase and lipase serum levels are decreased
• B. The white blood cell count (WBC) is decreased
• C. The conjugated and unconjugated bilirubin levels are decreased
• D. The blood urea nitrogen (BUN) serum level is decreased

Correct answer: A

Rationale: The correct answer is A. Amylase and lipase are enzymes specifically related to pancreatitis. A decrease in their serum levels indicates improvement in pancreatitis. White blood cell count (WBC), choices C and D, are not direct markers for pancreatitis improvement. Bilirubin levels, choice C, are more related to liver function rather than pancreatitis. Blood urea nitrogen (BUN) level, choice D, is a marker for kidney function, not pancreatitis.

2. During a physical assessment of a newborn, which of the following findings should the nurse prioritize reporting?

• A. Head circumference of 40 cm
• B. Chest circumference of 32 cm
• C. Acrocyanosis and edema of the scalp
• D. Heart rate of 160 bpm and respirations of 40/min

Correct answer: A

Rationale: The correct answer is A. A head circumference of 40 cm is abnormally large for a newborn and could indicate conditions like hydrocephalus or other abnormalities, making it a crucial finding to report. Choices B, C, and D are within normal parameters for a newborn and do not pose immediate concerns. Chest circumference of 32 cm is a normal finding. Acrocyanosis and edema of the scalp are common in newborns due to physiological adaptations. A heart rate of 160 bpm and respirations of 40/min may be within the normal range for a newborn.

3. In patients receiving chemotherapy, which nutrient is often supplemented to manage mucositis?

• A. Vitamin E
• B. Vitamin B12
• C. Zinc
• D. Calcium

Correct answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

4. What are three major causes of atherosclerosis?

• A. Hyperthyroidism, underweight, and poor appetite
• B. High blood cholesterol, high blood pressure, and cigarette smoking
• C. Constipation, peptic ulcer disease, and pancreatitis
• D. Kidney failure, edema, and sodium retention

Correct answer: B

Rationale: The correct answer is B: High blood cholesterol, high blood pressure, and cigarette smoking are three major causes of atherosclerosis. Atherosclerosis is mainly attributed to the buildup of cholesterol-rich plaques in the arteries, high blood pressure causing damage to the arterial walls, and the harmful effects of cigarette smoking on blood vessels. Choices A, C, and D are incorrect because they do not directly relate to the primary causes of atherosclerosis.

5. Which potential complication should the nurse assess for in the client with infective endocarditis who has embolization of vegetative lesions from the mitral valve?

• A. Pulmonary embolism
• B. Decreased urine output
• C. Hemoptysis
• D. Deep vein thrombosis

Correct answer: B

Rationale: The correct answer is B: Decreased urine output. When vegetative lesions from the mitral valve embolize, they can block blood flow to the kidneys, leading to renal infarction. This can result in decreased urine output. Choices A, C, and D are incorrect. Pulmonary embolism involves a blockage of an artery in the lungs, not directly related to embolization from the mitral valve. Hemoptysis is the coughing up of blood from the respiratory tract, which is not a direct consequence of embolization from the mitral valve. Deep vein thrombosis is the formation of a blood clot in a deep vein, unrelated to embolization from the mitral valve.
