Explanation
(A) The nurse should discourage the child from coughing, clearing the throat, or putting objects in his mouth.
These may induce bleeding. (B) Cool, clear liquids may be given when child is fully alert. Warm liquids may dislodge a blood clot. The nurse should avoid red- or brown-colored liquids to distinguish fresh or old blood from ingested liquid should the child vomit. (C) Gargles and vigorous toothbrushing could initiate bleeding.
(D) Postoperative hemorrhage, though unusual, may occur. The nurse should observe for bleeding by looking directly into the throat and for vomiting of bright red blood, continuous swallowing, and changes in vital signs.

(A) S1 and S2 in an infant with coarctation of the aorta are usually normal. S3 and S4 do not exist with this diagnosis. (B) Either no murmur will be heard or a systolic murmur from an associated cardiac defect will be heard along the left upper sternal border. A diastolic murmur is not associated with coarctation of the aorta. (C) Pulse pressure differences of>20 mm Hg exist between the upper extremities and the lower extremities. It is important to evaluate the upper and lower extremities with the appropriate- sized cuffs. (D) Femoral and pedal pulses will be diminished or absent in infants with coarctation of the aorta.

Explanation
(A) The client is losing blood supply to his left foot. Continuing to monitor the foot will not help restore the blood supply to the foot. (B) The physician should be notified immediately because the client is losing blood supply to his left foot and is in danger of losing the foot and/or leg. (C) The presenting symptoms are of an emergency nature and require immediate intervention. (D) This action would be giving the client false assurance.

Explanation:
(A) Bleeding is not a symptom of sickle cell anemia or sickle cell crisis. (B) Decreased blood viscosity leads to sickling of red blood cells. Increased fluid intake maintains adequate circulating blood volume and decreases the chance of sickling. (C) Hypoxia leads to sickling of cells. Flying in nonpressurized planes places the client in a situation of low O2 tension, which can lead to sickling. (D) Male and female clients with sickle cell disease can pass the trait on to their offspring. Therefore, this client should receive genetic counseling prior to having children.

Explanation:
(A) It is within the nurse's realm of practice to grant visiting privileges according to hospital policy. ECT treatments do not make clients sick. (B) Visitors are allowed and encouraged, particularly family members.
(C) Clients are usually awake within 1 hour posttreatment. Drowsiness wanes as the anesthetic wears off.
(D) A family member is encouraged to stay with the client after return to the unit. The nurse has used an opportunity to do family teaching and allay fears by explaining temporary side effects of the treatment.
