A 4-year-old, 44-pound Autistic patient is admitted to the ED with concerns of dehydration. He has been ordered to receive a 20ml/kg fluid bolus of normal saline over 30 minutes. At what rate would you set the IV pump?
- A. 880 ml/hour
- B. 800 ml/hour
- C. 440 ml/hour
- D. 400 ml/hour
Correct Answer: A
Rationale: The correct answer is A: 880 ml/hour. To calculate the IV pump rate, first, determine the total volume to be infused: 20 ml/kg x 44 lbs = 880 ml. Next, divide the total volume by the total time in hours: 880 ml / 1 hour = 880 ml/hour. This rate ensures the patient receives the prescribed fluid bolus over 30 minutes. Choice B is incorrect as it does not account for the specific weight of the patient. Choices C and D are incorrect as they do not follow the correct calculation based on the patient's weight.

Congenital heart defects are classified as all of the following? (Select all that apply)
- A. Mixed defects
- B. Obstruction defects
- C. Decreased pulmonary blood flow
- D. Acquired defects
Correct Answer: A,B,C
Rationale: Congenital heart defects can be classified based on pathophysiology. A: Mixed defects involve combination of two types of abnormalities, B: Obstruction defects involve narrowing/blockage in blood flow, and C: Decreased pulmonary blood flow includes defects leading to decreased blood flow to lungs. D: Acquired defects result from external factors and not present at birth. E, F, G are not applicable as no information is provided. Thus, A, B, C are correct based on classification of congenital heart defects.
A 15-year-old with type 1 diabetes mellitus presents with a fever and 48-hour history of vomiting. As the nurse, you note the child's breath has a fruity odour, his breathing is deep and rapid, and mom states he has become less arousable. You recognize these are the signs of:
- A. Acute Hypoglycemia
- B. Diabetic Ketoacidosis
- C. Hyperglycemia
- D. Polydipsia
Correct Answer: B
Rationale: The correct answer is B: Diabetic Ketoacidosis (DKA). The fruity odor of breath, deep and rapid breathing (Kussmaul breathing), and altered mental status are classic signs of DKA. In DKA, the body produces excess ketones due to lack of insulin, leading to metabolic acidosis. Acute Hypoglycemia (A) presents with low blood sugar levels, not high as in DKA. Hyperglycemia (C) is a general term for high blood sugar without the specific ketone production seen in DKA. Polydipsia (D) refers to excessive thirst, not the symptoms described in the scenario.
When preparing your pediatric patient for his cardiac assessment, which element would you start with for the assessment?
- A. Assess peripheral pulses
- B. Auscultate heart rate and rhythm
- C. Evaluate chest rise
- D. Palpate liver margins
Correct Answer: B
Rationale: The correct answer is B: Auscultate heart rate and rhythm. This is the first step in a pediatric cardiac assessment because it provides crucial information about the heart's function. Listening to the heart helps identify any abnormalities in heart sounds, such as murmurs or irregular rhythms, which can indicate underlying cardiac issues. Assessing peripheral pulses (choice A) may be important but comes after evaluating the heart. Evaluating chest rise (choice C) is important for respiratory assessment, not specifically for cardiac assessment. Palpating liver margins (choice D) is more relevant for assessing hepatomegaly, not typically the initial step in a cardiac assessment.
Which is the correct positioning of a child experiencing epistaxis:
- A. The child should be placed in a prone position
- B. The child should be placed in a supine position
- C. The child should be sitting with their head tilted back
- D. The child should sit up and lean forward
Correct Answer: D
Rationale: The correct positioning for a child experiencing epistaxis (nosebleed) is option D: the child should sit up and lean forward. This position helps prevent blood from flowing down the throat, reducing the risk of choking or aspiration. Sitting up also helps to reduce blood pressure in the vessels of the nose, aiding in the clotting process. Placing the child in a prone position (option A) can lead to blood flowing down the throat, causing potential airway obstruction. Placing the child in a supine position (option B) can also lead to blood going down the throat and may increase the risk of aspiration. Sitting with the head tilted back (option C) is not recommended as it can lead to blood running down the back of the throat and potentially into the airway. Therefore, option D is the correct choice for managing epistaxis in a child.
A sign specific to red blood cell destruction (hemolytic) anemia is:
- A. Jaundice
- B. Pica
- C. Anorexia
- D. Tachycardia
Correct Answer: A
Rationale: Jaundice is the correct answer for red blood cell destruction anemia because it results from the breakdown of red blood cells, causing an increase in bilirubin levels. Jaundice presents as yellowing of the skin and eyes. Pica (eating non-food items), anorexia (loss of appetite), and tachycardia (rapid heart rate) are not specific signs of hemolytic anemia. Jaundice is a key indicator due to the excess bilirubin released from the destruction of red blood cells.
