Nursing Elites

1. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

2. A child is refusing to use the potty and having accidents, even though he has achieved toilet training. This is an example of which type of behavior?

• A. Positive reinforcement
• B. Desensitization
• C. Phobia
• D. Regression

Correct answer: D

Rationale: The correct answer is D, regression. Regression occurs when a child reverts to an earlier behavior, such as having accidents after being successfully toilet trained. This regression often happens due to stress or changes in routine. Choices A, B, and C are incorrect because positive reinforcement involves encouraging desired behavior, desensitization is a process of reducing sensitivity to a stimulus, and phobia is an intense fear or aversion to a specific object or situation, none of which directly apply to the described situation of the child having accidents after being toilet trained.

3. What is the priority nursing intervention for a child with epiglottitis?

• A. Administer antibiotics
• B. Maintain airway patency
• C. Provide hydration
• D. Monitor vital signs

Correct answer: B

Rationale: The correct answer is B: Maintain airway patency. When dealing with a child with epiglottitis, the priority nursing intervention is to ensure airway patency to prevent airway obstruction, which can lead to respiratory distress or failure. Administering antibiotics (choice A) is important to treat the infection, but airway management takes precedence. Providing hydration (choice C) and monitoring vital signs (choice D) are essential aspects of care but are secondary to securing the airway in a child with epiglottitis.

4. What is the primary treatment for Kawasaki disease?

• A. Corticosteroids
• B. Intravenous immunoglobulin
• C. Antibiotics
• D. Antivirals

Correct answer: B

Rationale: The correct answer is B, Intravenous immunoglobulin (IVIG). IVIG is the primary treatment for Kawasaki disease, an acute vasculitis that mainly affects children under 5 years old. Early administration of IVIG is crucial as it helps reduce the risk of coronary artery aneurysms, which is the most serious complication of Kawasaki disease. Corticosteroids (Choice A) are not the primary treatment for Kawasaki disease and are not recommended due to potential adverse effects. Antibiotics (Choice C) are not indicated for the treatment of Kawasaki disease as it is not caused by a bacterial infection. Antivirals (Choice D) are also not part of the standard treatment for Kawasaki disease, as it is not caused by a viral infection.

5. What factor predisposes an infant to fluid imbalances?

• A. Decreased surface area
• B. Lower metabolic rate
• C. Immature kidney functioning
• D. Decreased daily exchange of extracellular fluid

Correct answer: C

Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.
