Nursing Elites

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. What is the most likely cause of a sudden onset of respiratory distress in a 5-year-old child with no fever?

• A. Infection of the lower airways.
• B. A progressive upper airway infection.
• C. Inflammation of the upper airway.
• D. A foreign body airway obstruction.

Correct answer: D

Rationale: A sudden onset of respiratory distress in a child without fever is most likely due to a foreign body airway obstruction. This obstruction can rapidly lead to difficulty breathing, stridor, and other signs of respiratory distress without necessarily causing a fever. Prompt recognition and intervention are crucial in such cases to prevent further complications and ensure the child's airway remains clear.

3. Mrs. Byers tells the nurse that she is very worried because her 2-year-old child does not finish his meals. What should the nurse advise the mother?

• A. Make the child seat with the family in the dining room until he finishes his meal
• B. Provide quiet environment for the child before meals
• C. Do not give snacks to the child before meals
• D. Put the child on a chair and feed him

Correct answer: C

Rationale: Providing a quiet environment can help the child focus on eating.

4. What comment made by a parent of a 1-month-old would alert the nurse about the presence of a congenital heart defect?

• A. He is always hungry.
• B. He tires out during feedings.
• C. He is fussy for several hours every day.
• D. He sleeps all the time.

Correct answer: B

Rationale: Observing a 1-month-old tiring out during feedings should alert the nurse to the possibility of a congenital heart defect. This symptom may indicate that the infant is expending excess energy to compensate for a heart issue, leading to fatigue during feeding. Choices A, C, and D do not directly relate to a congenital heart defect. Being always hungry, fussy, or sleeping a lot are not specific signs of a congenital heart defect in a 1-month-old.

5. When assisting ventilations in a 4-year-old child with a bag-valve mask, what should the EMT do?

• A. Deliver each breath over 2 to 3 seconds.
• B. Ensure the appropriate mask size is used.
• C. Block the pop-off valve if needed to achieve adequate chest rise.
• D. Reassess the pulse rate after 60 seconds.

Correct answer: C

Rationale: When assisting ventilations in a 4-year-old child with a bag-valve mask, the EMT should block the pop-off valve if needed to achieve adequate chest rise. This action helps ensure effective ventilation and adequate oxygenation in the child. Blocking the pop-off valve allows for better control over the volume of air delivered and can help maintain positive pressure in the airway, assisting in improving oxygenation and ventilation in the child. Choices A, B, and D are incorrect because delivering each breath over 2 to 3 seconds is a general guideline but may need adjustment based on patient response, ensuring the appropriate mask size is important but not the primary concern in this scenario, and reassessing the pulse rate is not directly related to the ventilation technique being discussed.
