1. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?
- A. 1000 mg
- B. 750 mg
- C. 500 mg
- D. 250 mg
Correct answer: A
Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.
2. During the initial assessment of the newborn, which of the following data would be considered normal?
- A. Chest circumference 31.5 cm, head circumference 33.5 cm
- B. Chest circumference 30 cm, head circumference 29 cm
- C. Chest circumference 38 cm, head circumference 31.5 cm
- D. Chest circumference 32.5 cm, head circumference 36 cm
Correct answer: A
Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.
3. Beta-adrenergic agonists such as albuterol are given to Reggie, a child with asthma, to primarily do which of the following?
- A. Dilate the bronchioles
- B. Reduce secondary infections
- C. Decrease postnasal drip
- D. Reduce airway inflammation
Correct answer: A
Rationale: Beta-adrenergic agonists like albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.
4. When using the Ballard gestational assessment tool on a newborn, which of the following tests should be performed after the first hour of birth, allowing the newborn to recover from the stress of birth?
- A. Arm recoil
- B. Square window sign
- C. Scarf sign
- D. Popliteal angle
Correct answer: A
Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.
5. Which of the following are clinical types of diarrhoea EXCEPT?
- A. Acute watery
- B. Bloody diarrhoea
- C. Persistent diarrhoea
- D. Secretory diarrhoea
Correct answer: D
Rationale: Secretory diarrhoea is not a clinical type but a distinct mechanism of diarrhoea characterized by increased electrolyte secretion. Acute watery, bloody, and persistent diarrhoea are recognized clinical types associated with different underlying causes and pathophysiologies. Acute watery diarrhoea is common in infectious gastroenteritis, bloody diarrhoea can be caused by inflammatory conditions or infections, and persistent diarrhoea typically lasts for more than 14 days due to various reasons like infections, malabsorption, or inflammatory bowel diseases.
