1. 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.

2. What assessment finding places a newborn at risk for developing physiologic jaundice?

• A. Cephalohematoma
• B. Mongolian spots
• C. Telangiectatic nevi
• D. Molding

Correct answer: A

Rationale: The correct answer is A, Cephalohematoma. Physiologic jaundice in newborns can occur due to the breakdown of excess red blood cells. A cephalohematoma, a collection of blood caused by ruptured blood vessels between a cranial bone's surface and periosteal membrane, can lead to increased red blood cell breakdown. This increased breakdown can contribute to the development of physiologic jaundice in newborns. Choices B, Mongolian spots, and C, Telangiectatic nevi, are both benign skin conditions and are not directly associated with increased red blood cell breakdown. Choice D, Molding, refers to the shaping of the fetal head during passage through the birth canal and is not related to the development of physiologic jaundice.

3. A child was brought to the emergency department with complaints of nausea, vomiting, and fruity-scented breath. The resident on duty diagnosed the child with diabetic ketoacidosis. Which of the following should the nurse expect to administer?

• A. Potassium chloride IV infusion.
• B. Dextrose 5% IV infusion.
• C. Ringer's Lactate.
• D. Normal saline IV infusion

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is a state of dehydration and electrolyte imbalance. Normal saline is the initial fluid of choice to help restore intravascular volume and improve electrolyte balance. It also helps to correct acidosis. Potassium chloride IV infusion is commonly added to the treatment regimen once kidney function is confirmed to prevent hypokalemia. Dextrose 5% IV infusion is not the first-line treatment for DKA as it can worsen hyperglycemia. Ringer's Lactate is not typically used as the initial fluid for managing DKA as it contains potassium and could worsen hyperkalemia.

4. In growing children, growth hormone deficiency results in short stature and very slow growth rates. Short stature may result from which of the following?

• A. Anterior pituitary gland hypofunction
• B. Posterior pituitary gland hyperfunction
• C. Parathyroid gland hyperfunction
• D. Thyroid gland hyperfunction

Correct answer: A

Rationale: Short stature in growing children can result from anterior pituitary gland hypofunction, which leads to growth hormone deficiency. The anterior pituitary gland plays a crucial role in stimulating the release of growth hormone, and when it is underactive (hypofunction), insufficient growth hormone is produced, resulting in short stature and slow growth rates.

5. Sometimes, people with congestive heart failure develop arrhythmias of the heart. These irregular rhythms can be conducive to developing a blood clot. Physicians frequently treat people with 'blood thinning' medicines that require regulation of the density of the blood. Which of these is the name for a blood-thinner?

• A. Erythromycin
• B. Tetracycline
• C. Warfarin
• D. Amoxicillin

Correct answer: C

Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.
