A nurse administers a thiazide diuretic to a client with renal compromise as prescribed by the primary health care provider. Which action by the nurse would be most appropriate if the client's blood urea nitrogen level increases?
A) Give prescribed magnesium supplements.
B) Withhold the next dose of the drug.
C) Administer the drug in a diluted form.
D) Increase the fluid intake for the client.
Ans: B
Feedback:
The nurse should withhold the drug or discontinue its use if the blood urea nitrogen (BUN) rises in the client with renal compromise who is receiving a thiazide diuretic. Magnesium supplements or add-ons may be provided to clients taking loop diuretics as they are prone to magnesium deficiency. The nurse should encourage fluid intake to prevent a fluid volume deficit in elderly clients who are particularly prone to fluid volume deficit and electrolyte imbalances when taking a diuretic. The nurse need not administer the drug in a diluted form since doing so will not have an effect on the blood urea nitrogen level.

C.W., a 36-year-old woman, was admitted several days ago with a diagnosis of recurrent inflammatory boweldisease (IBd) and possible small bowel obstruction (sBO)
C.W. is married, and her husband and 11-year-old son are supportive, but she has no extended family in the state. she has had IBd for 15 years and has been taking mesalamine (Asacol) for 15 years and prednisone 40mg/day for the past 5 years. she is very thin; at 5 feet 2 inches, she weighs 86 pounds and has lost 40 pounds over the past 10 years. she averages 5 to 10 loose stools per day. C.W.'s life has gradually become dominated by her disease, with anorexia, lactase deficiency, profound fatigue, frequent nausea and diarrhea, frequent hospitalizations for dehydration, and recurring, crippling abdominal pain that often strikes unexpectedly. The pain is incapacitating and relieved only by a small dose of diazepam (Valium), oral electrolyte solution (Pedialyte), and total bed rest. she confides in you that sexual activity is difficult: "It always causes diarrhea, nausea, and lots of pain. It's difficult for both of us." she is so weak she cannot stand without help. You indicate complete bed rest on the nursing care plan. Identify six priority problems for C.W.
