The nurse is collecting a stool specimen from a client. What stool characteristic indicates to the nurse that the client may have an upper gastrointestinal (GI) bleed?
Black, tarry stool
Clay-colored stool
Watery stool
Bright red blood in the stool
The Correct Answer is A
A. Black, tarry stool is indicative of blood that has been digested in the upper GI tract. The dark color is due to the action of digestive enzymes on blood.
B. Clay-colored stool is typically associated with biliary obstruction, not upper GI bleeding.
C. Watery stool can be caused by various conditions, including infections, inflammatory bowel diseases, and medications. It is not a specific indicator of upper GI bleeding.
D. Bright red blood in the stool is more likely to be associated with lower GI bleeding, such as from hemorrhoids or anal fissures.

Correct Answer is B
Explanation
A. Furosemide is a loop diuretic used to treat fluid overload by increasing urine output. In an Addisonian crisis, the primary issue is the severe lack of adrenal hormones rather than fluid overload. Administering furosemide is not indicated in this situation, as it does not address the underlying cause of the crisis or correct electrolyte imbalances that are common in Addisonian crisis.
B. This is a common intravenous fluid choice for managing Addisonian crisis. The 0.9% sodium chloride (normal saline) helps to restore blood volume and correct electrolyte imbalances, while the 5% dextrose provides glucose to support energy needs. This combination helps to address hypovolemia (low blood volume) and prevent hypoglycemia (low blood sugar), both of which can occur in an adrenal crisis.
C. Ketoconazole is an antifungal medication that can be used to treat Cushing’s syndrome, not Addisonian crisis. Insulin is used to manage blood glucose levels and would not be the primary treatment for Addisonian crisis. This option does not directly address the adrenal insufficiency or the immediate needs of an Addisonian crisis.
D. Addisonian crisis often presents with hyponatremia (low sodium) and hyperkalemia (high potassium) due to inadequate aldosterone production. Administering potassium chloride could exacerbate hyperkalemia, which is a concern in Addisonian crisis. Therefore, potassium chloride infusion is not appropriate and could worsen the electrolyte imbalance.
Correct Answer is ["20"]
Explanation
Desired dose / Available dose = Volume to administer 500 mg / (125 mg/5 mL) = Volume to administer Volume to administer = 20 mL
Therefore, the nurse should administer 20 mL of naproxen suspension per dose.
