Explanation:
(A) Respite care for the family may be needed, but it is not the primary goal of a preschool program. (B) Facilitation of optimal growth and development is essential for every child. (C) A demanding and challenging educational program may predispose the child to failure. Children with retardation should begin with simple and challenging educational programs. (D) Mental retardation associated with Down syndrome may not permit mainstream education. A preschoolprogram's primary goal is not preparation for mainstream education but continuation of optimal development.

(A)
Inotropic therapy will increase contractility, which will increase myocardial O2 demand.
(B)
Decreased heart rate to the point of bradycardia will increase coronary artery filling time. This should be used cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. (C) The goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and demand. (D) Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.

Explanation:
(A) A pressure diaper should be applied to discourage hemorrhage. (B) The baby can be fed by his mother soon after the procedure, once it is assessed that he is not in any distress and is stable. (C) Dressing changes should not be dry. Dry dressing will stick. (D) Cuddling after the procedure will hopefully quiet the baby. Feeding is also important if his feeding was withheld prior to the procedure or it is time for a feeding.

(A) There is a rise in glomerular filtration rate in the kidneys in conjunction with decreased tubular glucose reabsorption, resulting in glycosuria. (B) Insulin is inhibited by increased levels of estrogen. (C) Insulin is inhibited by increased levels of progesterone. (D) Human placental lactogen levels increase later in pregnancy. This hormonal antagonist reduces
insulin's effectiveness, stimulates lipolysis, and increases the circulation of free fatty acids.

(A) Vitamin C (ascorbic acid) is essential in promoting wound healing and collagen formation. (B) Vitamin B1 (thiamine) maintains normal gastrointestinal (GI) functioning, oxidizes carbohydrates, and is essential for normal functioning of nervous tissue. (C) Vitamin D regulates absorption of calcium and phosphorus from the GI tract and helps prevent rickets. (D) Vitamin A is necessary for the formation and maintenance of skin and mucous membranes. It is also essential for normal growth and development of bones and teeth.
