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. Your assessment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?

• A. Dry the infant briskly.
• B. Suction the mouth.
• C. Begin artificial ventilations.
• D. Begin chest compressions.

Correct answer: C

Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.

3. What is the appropriate ventilation rate for an apneic infant?

• A. 8 to 10 breaths/min.
• B. 10 to 12 breaths/min.
• C. 12 to 20 breaths/min.
• D. 20 to 30 breaths/min.

Correct answer: C

Rationale: During resuscitation of an apneic infant, the appropriate ventilation rate is 12 to 20 breaths per minute. This rate helps provide adequate oxygenation and ventilation without causing harm to the infant. Choice A (8 to 10 breaths/min) is too low and may not provide sufficient ventilation. Choice B (10 to 12 breaths/min) is slightly below the recommended range, which may not be optimal for effective resuscitation. Choice D (20 to 30 breaths/min) is too high and may lead to overventilation and potential harm to the infant by causing hypocapnia.

4. A child newly diagnosed with diabetes mellitus has been stabilized with insulin injections daily. A nurse prepares a discharge teaching plan regarding the insulin. The teaching plan should reinforce which of the following concepts?

• A. Always store insulin vials in the refrigerator
• B. Adjust insulin dosage before exercise
• C. Presence of ketones in urine indicates a need for less insulin
• D. Systematically rotate injection sites

Correct answer: D

Rationale: Systematically rotating injection sites is crucial to prevent tissue damage and ensure optimal insulin absorption. This practice helps in preventing lipohypertrophy, a condition characterized by fat accumulation at injection sites, which can affect insulin absorption and lead to inconsistent blood glucose control. By rotating injection sites, the risk of skin and tissue damage is minimized, and insulin's effectiveness is maintained over time.

5. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?

• A. 45%
• B. 63%
• C. 72%
• D. 54%

Correct answer: A

Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.
