1. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

2. Which of the following signs or symptoms is more common in children than adults following head trauma?

• A. nausea and vomiting
• B. altered mental status
• C. tachycardia and diaphoresis
• D. changes in pupillary reaction

Correct answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less skull compliance and higher brain water content, making them more susceptible to developing symptoms like nausea and vomiting. Altered mental status (choice B) can occur in both children and adults but is not more common in children. Tachycardia and diaphoresis (choice C) are nonspecific and can occur in both age groups. Changes in pupillary reaction (choice D) are not typically more common in children following head trauma compared to adults.

3. After clearing the airway of a newborn who is not in distress, what is the most important action to take next?

• A. Administer free-flow oxygen
• B. Clamp and cut the cord
• C. Keep the newborn warm
• D. Obtain an APGAR score

Correct answer: C

Rationale: Keeping the newborn warm is crucial immediately after clearing the airway to prevent hypothermia, which can lead to complications in newborns. Administering free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after ensuring the newborn's warmth. Obtaining an APGAR score is important but can be done after ensuring the newborn is kept warm and stable.

4. When evaluating the laboratory report of a 1-year-old infant’s hematocrit, a healthcare professional compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?

• A. 19% to 32%
• B. 29% to 41%
• C. 37% to 47%
• D. 42% to 69%

Correct answer: C

Rationale: The correct answer is C: 37% to 47%. The normal hematocrit range for a 12-month-old infant is between 37% to 47%, which reflects the expected blood volume and red blood cell levels for this age. Choice A (19% to 32%) and Choice B (29% to 41%) are too low and do not encompass the typical hematocrit range for a healthy 1-year-old. Choice D (42% to 69%) is too high and falls outside the usual hematocrit values for this age group.

5. A child has been diagnosed with classic hemophilia. A nurse teaches the child’s parents how to administer the plasma component factor VIII through a venous port. It is to be given 3 times a week. What should the nurse tell them about when to administer this therapy?

• A. Whenever a bleed is suspected
• B. In the morning on scheduled days
• C. At bedtime while the child is lying quietly in bed
• D. On a regular schedule at the parents’ convenience

Correct answer: B

Rationale: Administering factor VIII in the morning on scheduled days ensures that there is a consistent level of the plasma component throughout the day, especially when the child is active. This timing helps to maintain adequate levels of factor VIII to prevent bleeding episodes. Choice A is incorrect because administering factor VIII only when a bleed is suspected would not provide the consistent prophylactic coverage needed for children with hemophilia. Choice C is incorrect as bedtime administration may not be practical for ensuring the plasma component is available during the child's active hours. Choice D is incorrect because administering factor VIII on a regular schedule, rather than at specific times of the day, may not optimize its effectiveness in preventing bleeding episodes.
