(A)
Apgar scores are not related to the infant's care, but to the infant's physical condition.
(B)
Apgar scores assess the current physical condition of the infant and are not related to future environmental adaptation. (C) The purpose of the Apgar system is to evaluate the physical condition of the newborn at birth and to determine if there is an immediate need for resuscitation. (D) Congenital malformations are not one of the areas assessed with
Apgar scores.

Explanation
(A) Fluid volume deficit resulting from fluid shifts to the interstitial spaces occurs in the first 48 hours. (B) Forty-eight hours to 72 hours after the burn injury and fluid resuscitation, capillary permeability is restored and fluid requirements decrease. Interstitial fluid returns rapidly to the vascular compartment, and the nurse must monitor the child for signs and symptoms of hypervolemia. (C) Increased cardiac output results as fluids shift back to the vascular compartment. (D) Hypertension is the result of hypervolemia.

(A) This observation can be made during the taking-in phase when the mother's needs are more important. (B) This observation can be made during the taking-hold phase when the mother is actively involved with herself and the infant. (C, D) This observation can be made during the taking-in phase.

Explanation
(A) Acetaminophen (Tylenol) has analgesic and antipyretic actions approximately equivalent to those of aspirin. It produces analgesia possibly by action on the peripheral nervous system. It reduces fever by direct action on the hypothalamus heat-regulating center with consequent peripheral vasodilation. It is generally used for temporary relief of mild to moderate pain, such as a simple headache, minor joint and muscle pains, and control of fever. (B) Meperidine is a narcotic agonist analgesic with properties similar to morphine except that it has a shorter duration of action and produces less depression of urinary retention and smooth muscle spasm.
It is used for moderate to severe pain, for a preoperative medication, for support of anesthesia, and for obstetrical analgesia. In a postoperative TURP client, it would be used in conjunction with other medications for relief of moderate to severe pain, but not specifically for bladder spasms associated with TURP surgery.
(C) Promethazine hydrochloride is an antihistamine, antiemetic preparation. It exerts antiserotonin, anticholinergic, and local anesthetic actions. It is used for symptomatic relief of various allergic conditions, motion sickness, nausea, and vomiting. It is used for preoperative, postoperative, and obstetrical sedation and as an adjunct to analgesics for control of pain. (D) This answer is correct because aminocaproic acid is prescribed specifically for hematuria. Aminocaproic acid is excreted in the urine. The nurse should be alert for possible signs of thrombosis, particularly in the extremities.

(A) Adequate air exchange and tissue oxygenation depend on competent respiratory function. Checking the airway is the nurse's priority action. (B) Obtaining the vital signs is an important action, but it is secondary to airway management. (C) Reorienting a client to time, place, and person after surgery is important, but it is secondary to airway and vital signs. (D) Airway management takes precedence over physician's orders unless they specifically relate to airway management.
