1. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

2. Which of the following techniques represents the MOST appropriate method of opening the airway of an infant with no suspected neck injury?

• A. Perform the technique as you would for an older child or adult.
• B. Lift up the chin and hyperextend the neck.
• C. Gently lift the chin while maintaining slight flexion of the neck.
• D. Tilt the head back without hyperextending the neck.

Correct answer: D

Rationale: Tilting the head back without hyperextending the neck is the safest way to open an infant's airway. Hyperextending the neck can potentially cause harm to the infant, making option D the most appropriate method for opening an infant's airway without suspected neck injury.

3. Which of the following is not a clinical type of diarrhea?

• A. Acute diarrhea
• B. Bloody diarrhea
• C. Persistent diarrhea
• D. Secretory diarrhea

Correct answer: B

Rationale: Bloody diarrhea is not typically classified as a clinical type of diarrhea. The clinical types of diarrhea commonly include acute, persistent, and secretory diarrhea, which are characterized by different mechanisms and durations. Bloody diarrhea usually indicates the presence of blood in the stool, which can be a sign of various underlying conditions but is not a specific clinical type of diarrhea.

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. You are dispatched to a residence for a 5-year-old child who is not breathing. Upon arrival, you find the child supine on the floor, cyanotic, and unresponsive. You should first:

• A. begin chest compressions.
• B. open the airway and give two rescue breaths.
• C. apply an AED and analyze the rhythm.
• D. ask the parent for the child's medical history.

Correct answer: B

Rationale: When encountering an unresponsive and not breathing child, the initial step is to open the airway and provide two rescue breaths. This action helps to deliver oxygen to the child's lungs and body, which is crucial in attempting to restore breathing and circulation. Chest compressions are not initiated first in pediatric cases unless the child has no signs of circulation after delivering rescue breaths. Applying an AED and analyzing the rhythm is not the initial step in a pediatric cardiac arrest scenario, as the primary focus should be on providing oxygenation. Asking the parent for the child's medical history is not the immediate priority when the child is unresponsive and not breathing, as interventions to support breathing and circulation should be the primary concern.
