The nurse is talking to the patient caregiver about discharge instructions for the patient.
They start to talk about blood flow through the body.
The caregiver asks the nurse about the hepatic portal system and why it is important.
The nurse responds that the Hepatic Portal System.
Drains the chest wall and empties into the superior vena cava.
Are arteries that supply oxygenated-rich blood to the sex glands.
Can be palpitated in the mid-upper arm in the antecubital space.
Carries blood from abdominal organs to the liver for processing before returning to the heart.
The Correct Answer is D
Choice A rationale:
The hepatic portal system does not drain the chest wall and it does not empty into the superior vena cava.
Choice B rationale:
The hepatic portal system is not composed of arteries and it does not supply oxygenated-rich blood to the sex glands.
Choice C rationale:

Correct Answer is B
Explanation
The correct answer is choice B.
Choice A rationale:
A client who has NPO (nothing by mouth) status since midnight for an endoscopy could be at risk for fluid volume deficit. NPO status means the client has not been able to consume fluids orally, which could lead to a decrease in fluid intake. However, the risk is relatively low if the NPO status has only been in place since midnight and the client is otherwise healthy.
Choice B rationale:
A client who has heart failure and is receiving diuretic therapy is at a high risk for fluid volume deficit. Diuretics are used in heart failure to remove excess fluid from the body, but they can also lead to fluid volume deficit if not properly managed. This is because diuretics increase urine output, which can lead to a loss of fluid and electrolytes.
Choice C rationale:
A client who has gastroenteritis and is receiving oral fluids is not typically at risk for fluid volume deficit. Gastroenteritis can cause fluid loss through diarrhea and vomiting, but if the client is able to consume and retain oral fluids, they can usually maintain their fluid balance.
Choice D rationale:
A client who has end-stage kidney disease and will undergo dialysis could be at risk for fluid volume deficit, but this risk is typically well-managed during dialysis. Dialysis removes waste and excess fluid from the blood, and fluid intake is carefully monitored and adjusted based on the individual’s needs. Therefore, while there is a potential risk, it is usually well-controlled under the care of healthcare professionals.
Correct Answer is B
Explanation
Choice A rationale:
Urine specific gravity 1.020 is within the normal range (1.005-1.030), so it does not indicate fluid volume deficit.
Choice B rationale:
Urine output 15 mL/hr is less than the normal minimum of 30 mL/hr, indicating fluid volume deficit.
Choice C rationale:
Hct 43% is within the normal range (38.8-50.0 for men, 34.9-44.5 for women), so it does not indicate fluid volume deficit.
Choice D rationale:
BUN 12 mg/dL is within the normal range (7-20 mg/dL), so it does not indicate fluid volume deficit.
