1. Right Answer: A
Explanation: (A) The airway in children is much smaller than it is in adults. The diameter of the trachea in the newborn is 4 mm and that of the adult is 20 mm. A small change in the diameter of the airway can make a major difference in the pediatric client. (B) The tongue is proportionally larger in children and fills most of the oral cavity, thereby decreasing air space. (C) The entire pediatric airway is elastic. Elasticity diminishes with age, however. (D) The distances between respiratory structures are shorter than that of adults, and therefore organisms are able to move more rapidly down the throat, leading to more extensive respiratory involvement.
2. Right Answer: B

(B) The kidneys usually enlarge in these children, and sodium and water are retained. (C) Fluid restriction may be ordered to help reduce edema; however, monitoring for dehydration is indicated. (D) A high-cholesterol diet would not be indicated for any child, especially one with elevated blood pressure.
3. Right Answer: C

(B) Generous fluid intake reduces the concentration of urine. (C) Cotton is a natural, absorbent fabric. Nylon often predisposes the client to urinary tract infections. Dark, warm, moist areas are excellent media for bacterial growth.

(D) The parent will be able to offer support and comfort during and after the injection.
5. Right Answer: A
Explanation: (A) The volume to be infused should be diluted medication volume added to the volume control chamber (10 mL) plus the tubing volume (12 mL). The general formula for calculating IV medications for children is: Rate = Volume to Be Infused X Administration Set Drop Factor (microdrop: 60 gtts/min)Desired Time toInfuse in Minutes Rate = (10 + 12)22 X 60 30 = 44 mL/hr. (B, C, D) These values are incorrect.
