Vital signs are BP 140/90 mmHg, Pulse 118 beats/min., respirations 33 breaths/minute, and temperature, 98.0F. Which subjective data supports a diagnosis of renal calculi?

History of mild flu symptoms last week.

Dark-colored coffee-ground emesis.

Pain radiating to the right upper quadrant.

Dark, scanty urine output.

Answer and Explanation

The Correct Answer is D

Choice A rationale: This is not relevant to the current condition of the patient and does not support a diagnosis of renal calculi.

Choice B rationale: This is a sign of upper gastrointestinal bleeding, which can have many causes such as peptic ulcer, gastritis or esophageal varices. It is not related to renal calculi or urinary tract problems.

Choice C rationale: Renal calculi usually causes pain which usually radiates anteriorly to the lower abdomen, groin, labia, testicles or the perineum depending on the location of the stone.

Choice D rationale: This is a sign of hematuria, which is blood in the urine caused by the passage of renal calculi (kidney stones) through the urinary tract. Hematuria can also cause the urine to appear dark or brown in color.

Correct Answer is A

Explanation

Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate

Plugging in the given values, we get:

units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10

units of insulin per hour = 5

Therefore, the client is receiving 5 units of insulin every hour.

Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.

Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.

Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.

A. Peptic Ulcer Disease B. Gastroenteritis C. Acute Pancreatitis D. Diverticulitis

Correct Answer is C

Explanation

Choice A rationale: Peptic ulcer disease doesn't typically present with ecchymosis around the umbilicus (Cullen's sign) or significantly elevated amylase and lipase levels.

Choice B rationale: Gastroenteritis is less likely given the specific symptoms, physical exam findings, and laboratory results indicating pancreatic involvement.

Choice C rationale: Acute pancreatitis fits the clinical picture with epigastric pain after heavy alcohol use, persistent nausea/vomiting, tenderness, and elevated amylase and lipase levels.

Choice D rationale: Diverticulitis typically presents with symptoms more localized to the lower abdomen and doesn't cause the characteristic findings seen in this scenario.
