A 47-year-old client has been admitted to the general surgery unit for bowel obstruction. The doctor has ordered that an NG tube be inserted to aid in bowel de-compression. When preparing to insert a NG tube, the nurse measures from the:
Answer(s): D
(A) This measurement is _50 cm (4849 cm). Fifty centimeters is considered the length necessary for the distal end of the tube to be in place in the stomach. This measurement is too short. (B) This measurement is _50 cm (4748 cm). Fifty centimeters is considered the lengthnecessary for the distal end of the tube to be in place in the stomach. This measurement is too short. (C) This measurement gives an approximate indication of the length necessary for the distal end of the tube to be in place in the stomach, but it is not as accurate as actually measuring the client (nose-earxiphoid). (D) This is the correct measurement of 50 cm from the tip of the client's nose to the tip of the earlobe to the xiphoid process (called the NEX [nose-ear-xiphoid] measurement). It is approximately equal to the distance necessary for the distal end of the tube to be located in the correct position in the stomach.
A client is having a pneumonectomy done today, and the nurse is planning her postoperative care. Nursing interventions for a postoperative left pneumonectomy would include:
(A) Chest tubes are usually not necessary in a pneumonectomy because there is no lung to re-expand on the operative side. (B) The pneumonectomy client should be positioned on the back or operated side because the sutured bronchial stump may open, allowing fluid to drain into the unoperated side and drown the client. (C) The client should not have a pillow under the shoulder and back because of the subscapular incision. (D) Rales are commonly heard over the base of the remaining lung, but an increase could indicate circulatory overload and therefore should be closely monitored.
Decreased pulmonary blood flow, right-to-left shunting, and deoxygenated blood reaching the systemic circulation are characteristic of:
Answer(s): A
(A) Tetralogy of Fallot is the most common cyanotic heart defect, which includes a VSD, pulmonary stenosis, an overriding aorta, and ventricular hypertrophy. The blood flow is obstructed because the pulmonary stenosis decreases the pulmonary blood flow and shunts blood through the VSD, creating a right-to-left shunt that allows deoxygenated blood the reach the systemic circulation. (B) A VSD alone creates a left-to-right shunt.The pressure in the left ventricle is greater than that of the right; therefore, the blood will shunt from the left ventricle to the right ventricle, increasing the blood flow to the lungs. No deoxygenated blood will reach the systemic circulation. (C) In patent ductus arteriosus, the pressure in the aorta is greater than in the pulmonary artery, creating a left-to-right shunt. Oxygenated blood from the aorta flows into the unoxygenated blood of the pulmonary artery. (D) Transposition of the great arteries results in two separate and parallel circulatory systems. The only mixing or shunting of blood is based on the presence of associated lesions.
