1. Which sign is indicative of developmental dysplasia of the hip in infants?

• A. Ortolani sign
• B. Romberg sign
• C. Trendelenburg sign
• D. Gower's sign

Correct answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

2. Baby M is 5 months old. You notice that she now has the ability to grasp objects between her fingers and opposing thumb. This is known as:

• A. Parachute reflex
• B. Grasp reflex
• C. Pincer grasp
• D. Prehension

Correct answer: C

Rationale: The correct answer is C: Pincer grasp. The pincer grasp is the ability to hold objects between the thumb and another finger, typically developed around 9-12 months. At 5 months, it is early for a pincer grasp to fully develop, but the beginning of this skill can be seen as early as 5 months. Choices A and B are incorrect as the parachute reflex is a protective response to falling and the grasp reflex is an automatic response to touch. Choice D, prehension, is a general term for the act of grasping or holding objects, but it does not specifically refer to holding objects between the thumb and fingers like the pincer grasp does.

3. Which statement regarding bottle mouth caries requires further teaching?

• A. Caries can be decreased by putting an infant to bed with a bottle of milk or sweetened juice
• B. Eliminating the bedtime bottle or substituting water is recommended
• C. Sugar pools within the oral cavity cause severe decay
• D. It is often seen in children between 18 months and 3 years

Correct answer: A

Rationale: The correct answer is A. Putting an infant to bed with a bottle of milk or sweetened juice increases the risk of bottle mouth caries rather than decreasing it. This statement requires further teaching as it provides incorrect information. Choice B is correct as eliminating the bedtime bottle or substituting water is recommended to prevent bottle mouth caries. Choice C is also correct as sugar pooling within the oral cavity can indeed cause severe decay. Choice D is correct as bottle mouth caries is often observed in children between 18 months and 3 years.

4. What is a common cause of acquired aplastic anemia in children?

• A. Deficient diet
• B. Ingestion of drugs such as chloramphenicol or antiepileptics
• C. Congenital defects
• D. Injury

Correct answer: B

Rationale: The correct answer is B. Acquired aplastic anemia in children is often caused by exposure to certain drugs, such as chloramphenicol or antiepileptics, which can lead to bone marrow failure and a decrease in all types of blood cells. Choices A, C, and D are incorrect because aplastic anemia is not commonly caused by deficient diet, congenital defects, or injury in children.

5. A child is admitted with renal failure. Which of these findings should the nurse expect?

• A. Decreased BUN
• B. Azotemia and oliguria
• C. Increased glomerular filtration rate (GFR)
• D. Polyuria and elevated creatinine clearance

Correct answer: B

Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.
