1. Warning signs that indicate dehydration include all EXCEPT:

• A. Poor skin turgor
• B. Increased urine output
• C. Tachycardia
• D. Eager to drink

Correct answer: B

Rationale: The correct answer is B. Increased urine output is not a warning sign of dehydration; it typically decreases with dehydration. Dehydration often presents with poor skin turgor, tachycardia, and an increased sensation of thirst (eager to drink) as the body tries to compensate for fluid loss. Choices A, C, and D are all correct warning signs of dehydration. Poor skin turgor is a result of decreased skin elasticity due to fluid loss. Tachycardia, an elevated heart rate, can be a compensatory mechanism to maintain cardiac output in dehydration. Feeling eager to drink is a common symptom of dehydration as the body attempts to restore fluid balance.

2. What is the MOST common cause of shock in infants and children?

• A. Severe allergic reaction
• B. Dehydration
• C. Accidental poisoning
• D. Cardiac failure

Correct answer: B

Rationale: Dehydration is the most common cause of shock in infants and children. In children, the body's fluid reserves are smaller compared to adults, making them more susceptible to dehydration, which can lead to shock if not promptly addressed. Severe allergic reactions, accidental poisoning, and cardiac failure can also cause shock, but dehydration is the most frequent cause in this age group.

3. Which of the following is a more reliable indicator of perfusion in children than in adults?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Capillary refill

Correct answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

4. When drawing blood from the diabetic patient for a glycosylated hemoglobin (HBA1c) test, the nurse explains to the woman that the test is used to determine:

• A. The highest glucose level in the past week.
• B. Her insulin levels.
• C. Glucose levels over the past three months.
• D. Her usual fasting glucose level.

Correct answer: C

Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.

5. Why should small children ride in the backseat of a vehicle?

• A. They are much less likely to be ejected from the vehicle.
• B. The back of the front seat will provide a cushion during a crash.
• C. They can experience severe injury or death if the airbag deploys.
• D. Their legs are highly prone to injury from striking the dashboard.

Correct answer: C

Rationale: Small children should ride in the backseat of a vehicle primarily to avoid severe injury or death that may occur if the airbag deploys. In the event of a crash, the force of an airbag deployment can be dangerous for a child seated in the front seat. Placing them in the backseat reduces the risk of serious harm from airbag impact and is a safer seating position for young passengers.
