A patient with cholelithiasis asks the nurse why he/she is jaundiced. What is the nurse's best answer?
“Your liver cannot manufacture bile."
"Your pancreas is no longer able to manufacture insulin."
"Your gall bladder is not contracting properly."
"A gallstone can prevent bile from flowing into the Intestines."
The Correct Answer is D
A. "Your liver cannot manufacture bile": The liver can still manufacture bile, but the problem lies in bile flow, not production.
B. "Your pancreas is no longer able to manufacture insulin": This statement refers to diabetes, not cholelithiasis.
C. "Your gall bladder is not contracting properly": While gallbladder dysfunction can cause pain, jaundice specifically occurs due to bile flow obstruction, not just poor contraction.
D. "A gallstone can prevent bile from flowing into the intestines": Gallstones can obstruct the bile ducts, leading to a buildup of bilirubin in the blood, which manifests as jaundice.

Correct Answer is ["15.94"]
Explanation
Convert the ordered dose to mcg/min:
- 10 mcg/kg/min × 85 kg = 850 mcg/min
Convert the available dose to mcg/mL:
- 800 mg = 800,000 mcg in 250 mL
Concentration = 800,000 mcg ÷ 250 mL
= 3200 mcg/mL
Calculate the infusion rate:
Infusion rate (mL/hour) = [Desireddose(mcg/min) ÷Concentration(mcg/mL)] ×60 min/hour
Infusion rate = (850 mcg/min ÷ 3200 mcg/mL) × 60 min/hour
= 15.94 mL/hour
The IV pump should be set to infuse at approximately 15.94 mL/hour to deliver the ordered dose of dopamine at 10 mcg/kg/min for a patient weighing 85 kg. This ensures the appropriate therapeutic effect.
Correct Answer is C
Explanation
A. Partially compensated Metabolic Alkalosis: This is incorrect because the pH is within normal limits (7.35-7.45), and the elevated PaCO2 and bicarbonate suggest a respiratory issue rather than a metabolic one.
B. Fully compensated Metabolic Acidosis: This is incorrect because the primary disturbance is respiratory, not metabolic. A compensated metabolic acidosis would typically show a low PaCO2 as compensation.
C. Fully compensated Respiratory Acidosis: Correct. The pH is within the normal range, indicating full compensation. The elevated PaCO2 and bicarbonate reflect a chronic respiratory acidosis that has been compensated by the kidneys.
D. Partially compensated Respiratory Alkalosis: This is incorrect because in respiratory alkalosis, the PaCO2 would be low, not high.
