1. What is the most common cause of HHNS?

• A. Insulin overdose
• B. Removal of the adrenal gland
• C. Undiagnosed, untreated hyperpituitarism
• D. Undiagnosed, untreated diabetes mellitus

Correct answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

2. The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?

• A. 30 drops per minute
• B. 25 drops per minute
• C. 20 drops per minute
• D. 22 drops per minute

Correct answer: C

Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

3. Which of the following differentiates ulcerative colitis from Crohn's disease?

• A. Crohn's disease primarily affects the left colon and rectum, while ulcerative colitis most often affects the right colon and distal ileum.
• B. Crohn's disease presents with shallow ulcerations, whereas ulcerative colitis presents with a cobblestone appearance of the mucosal lining.
• C. The extent of involvement is noncontiguous and segmented with Crohn's disease, whereas it is contiguous and diffuse with ulcerative colitis.
• D. Crohn's disease has primarily mucosal involvement, whereas it is transmural with ulcerative colitis.

Correct answer: C

Rationale: The correct answer is C. Crohn's disease is characterized by noncontiguous, segmented involvement, meaning it can affect different areas with healthy tissue in between, while ulcerative colitis involves continuous areas of inflammation. Choices A, B, and D are incorrect because Crohn's disease can affect any part of the digestive tract from mouth to anus, can present with shallow ulcerations or deep fissures, and is transmural, meaning it affects the entire thickness of the bowel wall. On the other hand, ulcerative colitis typically affects the colon and rectum, presents with a continuous pattern of inflammation, and primarily involves the mucosal lining of the colon.

4. Which patient is at greatest risk for papilledema?

• A. An elderly patient with cataracts and macular degeneration
• B. A male patient with hypothyroidism
• C. A male patient with hyperthyroidism
• D. An adolescent with a closed head injury

Correct answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.

5. How many calories per kilogram does an average full-term infant require when the infant is around 1-2 months old?

• A. 140 calories per kilogram per day
• B. 120 calories per kilogram per day
• C. 100 calories per kilogram per day
• D. 160 calories per kilogram per day

Correct answer: B

Rationale: An average full-term infant requires about 120 calories per kilogram per day at 1-2 months old. This amount is essential for their growth and development during this critical stage. Choices A, C, and D are incorrect as they provide calorie amounts that are either too high or too low for an average full-term infant at 1-2 months old, which could potentially lead to health issues or inadequate nutrition.
