Explanation
(A) Fever, tachycardia, and tachypnea are the classic early signs of septic shock in children. (B) Respiratory distress, cold skin, and pale extremities are later signs of septic shock. (C) Elevated blood pressure, hyperventilation, and thready pulses are later signs of septic shock. (D) Normal pulses, hypotension, and oliguria are not early signs of septic shock.

Explanation:
(A) This time is incorrect because regular insulin would peak after the teenager has eaten breakfast. (B) This time is incorrect because it is after lunch when the NPH peaks. (C) Regular insulin peaks in 2-3 hours and has a duration of 4-6 hours. NPH insulin's onset is 4-6 hours and peaks in 8-16 hours. Blood sugar would peak after meals and be lowest before meals and during the night. (D) This time is incorrect because it is before the NPH and after the regular insulin peak times.

(A) Tetralogy of Fallot is the most common cyanotic heart defect, which includes a VSD, pulmonary stenosis, an overriding aorta, and ventricular hypertrophy. The blood flow is obstructed because the pulmonary stenosis decreases the pulmonary blood flow and shunts blood through the VSD, creating a right-to-left shunt that allows deoxygenated blood the reach the systemic circulation. (B) A VSD alone creates a left-to-right shunt. The pressure in the left ventricle is greater than that of the right; therefore, the blood will shunt from the left ventricle to the right ventricle, increasing the blood flow to the lungs. No deoxygenated blood will reach the systemic circulation. (C) In patent ductus arteriosus, the pressure in the aorta is greater than in the pulmonary artery, creating a left-to-right shunt. Oxygenated blood from the aorta flows into the unoxygenated blood of the pulmonary artery. (D) Transposition of the great arteries results in two separate and parallel circulatory systems. The only mixing or shunting of blood is based on the presence of associated lesions.

Explanation
(A) This statement describes a normal assessment finding of the lower extremities. (B) This assessment finding reflects problems caused by venous insufficiency. (C) Decreased or absentpedal pulses reflect a problem caused by arterial insufficiency. (D) The leg that is experiencing arterial insufficiency would be cool to touch due to the decreased circulation.

Explanation
(A) Educating the child about the pain may lessen anxiety. The child should be prepared for a potentially painful procedure but avoid suggesting pain. The nurse should allow the child his own sensory perception and evaluation of the procedure. (B) The nurse should avoid absolute descriptive statements and allow the child his own perception of the procedure. (C) The nurse should avoid evaluative statements or descriptions and give the child control in describing his reactions. (D) False statements regarding a painful procedure will cause a loss of trust between the child and the nurse.
