Explanation
(A) Bradycardia is an expected assessment during the postpartum period. (B) Diuresis can occur during labor and the postpartum period and is an expected physiological adaptation. (C) A return of rubra after the serosa period may indicate a postpartal complication. (D) Diaphoresis, especially at night, is an expected physiological change and does not indicate an infectious process. Bradycardia, diuresis, and diaphoresis are normal postpartum physiological responses to adjust the cardiac output and blood volume to the nonpregnant state.

(A) Hypokalemia can cause digoxin toxicity. Administration of KCl would prevent this. (B) Thyroid agents decrease digoxin levels. (C) Quinidine increases digoxin levels dramatically. (D) Theophylline is not noted to have an effect on digoxin levels.

Section: Questions Set F
Explanation:
(A) Fluids (nourishment) should be offered at regular intervals whether the client requests (or refuses) them or not. (B) Skin integrity and circulation of the extremities should be checked regularly while the client is restrained, not only before restraints are applied and after they are removed. (C) Vital signs should be checked at least every 2 hours. If the client remains agitated in restraints, vital signs should be monitored even more closely, perhaps every 1-2 hours. (D) Restraints should be released every 2 hours for exercise, one extremity at a time, to maintain muscle tone, skin and joint integrity, and circulation.

(A) Initial home treatment of croup includes placing the child in an environment of high humidity to liquefy and mobilize secretions. (B) Antihistamines should be avoided because they can cause thickening of secretions. (C) Drooling is a characteristic sign of airway obstruction and the child should be taken directly to the emergency room. (D) Crying increases respiratory distress and hypoxia in the child with croup. The nurse should promote methods that will calm the child.

Section: Questions Set E
Explanation:
(A) A radiant warmer maintains an optimal thermal environment by use of a thermal skin sensor taped to the infant. The warmer limits parental attachment, so, although appropriate, it is not an intervention that promotes infant attachment. (B) Warmed blankets prevent heat loss in the neonate by conduction. In addition, tactile stimuli promote crying and lung expansion. This intervention does not promote attachment, however. (C) Skin- to-skin contact is an effective way to conserve heat after delivery and promotes parental attachment following birth in the healthy term infant. The first period of reactivity lasts approximately 30 minutes following birth. A strong sucking reflex and an active, awake newborn characterize this period. (D) Surfaces of objects warmer than the infant promote overheating by conduction, and neonatal hyperthermia may result.
