- A. 0.12 second
- B. 0.20 second
- C. 0.24 second
- D. 0.40 second
Correct Answer: A

A client undergoes transurethral resection of the prostate (TURP). Which solution should the nurse have available postoperatively for continuous bladder irrigation (CBI)?
- A. Sterile water
- B. Sterile normal saline
- C. Sterile Dakin's solution
- D. Sterile water with 5% dextrose
Correct Answer: B
Rationale: Continuous bladder irrigation is done after TURP using sterile normal saline, which is isotonic. Sterile water is not used because the solution could be absorbed systemically, precipitating hemolysis and possibly kidney failure. Dakin's solution contains hypochlorite and is used only for wound irrigation in selected circumstances. Solutions containing dextrose are not introduced into the bladder.
A client is resuming a diet after a Billroth II procedure. To minimize complications associated with eating, which actions should the nurse teach the client? Select all that apply.
- A. Laying down after eating
- B. Eating a diet high in protein
- C. Drinking liquids with meals
- D. Eating six small meals per day
- E. Eating concentrated sweets only between meals
Correct Answer: A,B,D
Rationale: The client who has had a Billroth II procedure is at risk for dumping syndrome. The client should lie down after eating and avoid drinking liquids with meals to prevent this syndrome. The client should be placed on a dry diet that is high in protein, moderate in fat, and low in carbohydrates. Frequent small meals are encouraged, and the client should avoid concentrated sweets.
The nurse assesses the water seal chamber of a closed chest drainage system and notes fluctuations in the chamber. What intervention should the nurse implement?
- A. Unkinking the tubing
- B. Assessing for an air leak
- C. Documenting that the lung has reexpanded
- D. Documenting that the lung has not yet reexpanded
Correct Answer: D
Rationale: Fluctuations (tidaling) in the water seal chamber are normal during inhalation and exhalation until the lung reexpands and the client no longer requires chest drainage. If fluctuations are absent, it could indicate occlusion of the tubing or that the lung has reexpanded. Excessive bubbling in the water seal chamber indicates that an air leak is present.
The nurse provides information to a client diagnosed with gastroesophageal reflux disease (GERD). What information should the nurse include when discussing foods that contribute to decreased lower esophageal sphincter (LES) pressure and thus worsen the condition? Select all that apply.
- A. Alcohol
- B. Fatty foods
- C. Citrus fruits
- D. Baked potatoes
- E. Caffeinated beverages
- F. Tomatoes and tomato products
Correct Answer: A,B,C,E,F
Rationale: GERD occurs as a result of the backward flow (reflux) of gastrointestinal contents into the esophagus. The most common cause of GERD is inappropriate relaxation of the LES, which allows the reflux of gastric contents into the esophagus and exposes the esophageal mucosa to gastric contents. Factors that influence the tone and contractility of the LES and lower LES pressure include alcohol; fatty foods; citrus fruits; caffeinated beverages such as coffee, tea, and cola; tomatoes and tomato products; chocolate; nicotine in cigarette smoke; calcium channel blockers; nitrates; anticholinergics; high levels of estrogen and progesterone; peppermint and spearmint; and nasogastric tube placement. Baked potatoes would not contribute to worsening the problem.

- B. Proteinuria
- C. Hypertension
- D. Abdominal pain
- E. Increased weight
- F. Hypoalbuminemia
Correct Answer: A,B,D,E,F
Rationale: Nephrotic syndrome refers to a kidney disorder characterized by edema, proteinuria, and hypoalbuminemia. The child also experiences anorexia, fatigue, abdominal pain, respiratory infection, and increased weight. The child's blood pressure is usually normal or slightly below normal.
