A patient with cirrhosis is becoming lethargic and confused. Which of the following labs does the nurse expect the HCP (health care provider) to order?
PT/NR
Urea
Ammonia
Albumin
The Correct Answer is C
A. PT/INR: PT/INR is used to assess clotting function and liver synthetic function but does not directly relate to the symptoms of lethargy and confusion.
B. Urea: Urea levels are related to kidney function and protein metabolism but do not directly explain the symptoms of encephalopathy.
C. Ammonia: Elevated ammonia levels in cirrhosis can lead to hepatic encephalopathy, which presents as lethargy and confusion. The liver is unable to convert ammonia to urea, leading to its accumulation in the blood.
D. Albumin: Albumin levels are important in assessing nutritional status and fluid balance in cirrhosis but do not directly cause lethargy and confusion.

Correct Answer is B
Explanation
A. Imbalanced nutrition: Less than body requirements related to decreased oral intake: While this may be relevant, it is not the highest priority in acute appendicitis. Infection prevention is more critical.
B. Risk for infection related to possible rupture of appendix: The primary concern in appendicitis is the risk of rupture, leading to peritonitis and sepsis. This makes infection control the top priority.
C. Chronic pain related to appendicitis: Pain in appendicitis is acute, not chronic. Managing infection risk is more urgent.
D. Constipation related to decreased bowel motility and decreased fluid intake: Constipation is not a priority concern in the context of acute appendicitis. The risk of infection takes precedence.
Correct Answer is A
Explanation
A. Pulmonary crackles/rales: Left-sided heart failure leads to a buildup of fluid in the lungs, causing pulmonary congestion and crackles/rales on auscultation.
B. Weight gain: This is more commonly associated with right-sided heart failure due to fluid retention, though it can be seen in both types of heart failure.
C. Hepatomegaly: Hepatomegaly is typically associated with right-sided heart failure due to congestion in the systemic circulation.
D. Jugular vein distention: JVD is a sign of right-sided heart failure, as it indicates increased central venous pressure.
