Question 1 of 5
A client develops an intestinal obstruction postoperatively. A nasogastric tube is attached to low, intermittent suction with orders to 'Irrigate NG tube with sterile saline q1h and prn.' The rationale for using sterile saline, as opposed to using sterile water to irrigate the NG tube is:
Correct Answer: A
Rationale: Water is a hypotonic solution and will deplete electrolytes and cause metabolic acidosis when used for nasogastric irrigation. Irrigating with saline does not cause abdominal discomfort. Severe, colicky abdominal pain is a symptom of intestinal obstruction. Irrigating with water will not cause restlessness or insomnia in the postoperative client. Restlessness and insomnia can be emotional complications of surgery. A nasogastric tube placed in the stomach is used to decompress the bowel. Irrigating with saline ensures a patent, well-functioning tube. Irrigating with saline will not increase peristalsis.
Question 2 of 5
An obstructing stone in the renal pelvis or upper ureter causes:
Correct Answer: C
Rationale: Radiating pain in the urethra in both sexes, extending into the labia in females and into the testicle or penis in the male, indicates a stone in the middle or lower segment of the ureter. Urinary frequency and dysuria are caused by a stone in the terminal segment of the ureter within the bladder wall. An obstructing stone in the renal pelvis or upper ureter causes severe flank and abdominal pain with nausea, vomiting, diaphoresis, and pallor. Dull and aching pain may indicate early stages of hydronephrosis. Also, a stone in the renal pelvis or upper ureter causes severe flank and abdominal pain.
Question 3 of 5
Prior to his discharge from the hospital, a cardiac client is started on digoxin (Lanoxin) 25 mg po qd. The nurse initiates discharge teaching. Which of the following statements by the client would validate an understanding of his medication?
Correct Answer: A
Rationale: The first signs of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, and visual disturbances. The physician should be notified if any of these symptoms are experienced. The positive inotropic effects of digoxin increase cardiac output and result in an enhanced activity tolerance. 'Feeling better' indicates the drug is working and medication therapy must be continued. Clients should be taught to take their pulse prior to taking the digoxin. If their pulse rate becomes irregular, slows significantly, or is >100 bpm the physician should be notified. Antacids decrease the effectiveness of digoxin.
Question 4 of 5
The physician has ordered a low-residue diet for a client with Crohn's disease. Which food is not permitted in a low-residue diet?
Correct Answer: C
Rationale: A low-residue diet minimizes fiber and irritating foods; fried fish is high in fat and can irritate the gut, making it unsuitable for Crohn's disease.
