NCLEX-RN Exam Dumps - National Council Licensure Examination(NCLEX-RN)

(A) Ritodrine is a sympathomimetic α2-adrenergic agonist that can cause an elevation of blood glucose and plasma insulin in pregnant women. Hyperglycemia can occur in women with abnormal carbohydrate metabolism because of their inability to release more insulin. (B) Hypokalemia can occur resulting from the action of the _-mimetics. It results from a displacement of the extracellular potassium into the intracellular space. (C) Ritodrine causes vasodilation of vessel walls, which can lead to hypotension. The body compensates by increasing heart rate and pulse pressure. (D) There is a lowering of serum iron resulting from the action of _-mimetics to activate hematopoiesis.

(A) Central nervous system damage presents as seizures, decreased arousal, and absence of newborn reflexes. (B) In a diabetic mother, the infant is exposed to high serum glucose. The fetal pancreas produces large amounts of insulin, which causes hypoglycemia after birth. (C) Hypoglycemia is a common newborn problem. Increased insulin production causes hypoglycemia, not hyperglycemia. (D) These are not normal adaptive behaviors to extrauterine life.

(A) This answer is a miscalculation. (B) This answer is a miscalculation. (C)125 gtt/min. (D) This answer is a miscalculation.

(A) Air embolism is a potential complication of blood administration, but it is fairly rare and can be prevented by using good IV technique. (B) Circulatory overload is a potential complication of blood administration, but because this client is actively bleeding, she is not at high risk for overload. (C) Hypocalcemia is a potential complication of blood administration that occurs in situations where massive transfusion has occurred over a short period of time. It occurs because the citrate in stored blood binds with the client’s calcium. Another potential complication for which this client is especially at risk is hypothermia, which can be prevented by using a blood warmer to administer the blood. (D) Hypokalemia is not a complication of blood administration.

(A) The nurse should initiate actions to remove the most frequent cause of uterine displacement, which involves emptying the bladder. Notifying the physician is an inappropriate nursing action. (B) The pad count gives an estimate of blood loss, which is likely to increase with a boggy uterus; but this action does not remove the most frequent cause of uterine displacement, which is a full bladder. (C) Massage may firm the uterus temporarily, but if a full bladder is not emptied, the uterus will remain displaced and is likely to relax again. (D) The most common cause of uterine displacement is a full bladder.
