Question 3 of 5

Question 4 of 5
When planning care for the passive-aggressive client, the nurse includes the following goal:
Correct Answer: B
Rationale: Ceasing to use humor and sarcasm is a more appropriate goal, because this client uses these behaviors covertly to express aggression instead of being open with anger. Use of 'I' messages demonstrates proper use of assertive behavior to express anger instead of passive-aggressive behavior. Client is expected to complete share of work in therapeutic community because he has often obstructed other's efforts by failing to do his share. Client has used conveniently forgetting or withholding information as a passive-aggressive behavior, which is not acceptable.
Question 5 of 5
Which of the following findings would be abnormal in a postpartal woman?
Correct Answer: D
Rationale: Frequently the mother experiences a shaking chill immediately after delivery, which is related to a nervous response or to vasomotor changes. If not followed by a fever, it is clinically innocuous. The pulse rate during the immediate postpartal period may be low but presents no cause for alarm. The body attempts to adapt to the decreased pressures intra-abdominally as well as from the reduction of blood flow to the vascular bed. Urinary output increases during the early postpartal period (12-24 hours) owing to diuresis. The kidneys must eliminate an estimated 2000-3000 mL of extracellular fluid associated with a normal pregnancy. A temperature of 100.4°F (38°
C) may occur after delivery as a result of exertion and dehydration of labor. However, any temperature greater than 100.4°F needs further investigation to identify any infectious process.
