Impaired hepatic function:

Causes a deficiency of intrinsic factor and pernicious anemia

Causes lactose intolerance

Causes gastric reflux

Causes blood drug levels to reach toxic levels

Answer and Explanation

The Correct Answer is D

A. Causes a deficiency of intrinsic factor and pernicious anemia: Intrinsic factor is produced in the stomach, not the liver. Its deficiency leads to pernicious anemia.

B. Causes lactose intolerance: Lactose intolerance is due to lactase deficiency in the small intestine.

C. Causes gastric reflux: Gastroesophageal reflux is typically due to lower esophageal sphincter dysfunction.

D. Causes blood drug levels to reach toxic levels: The liver metabolizes drugs. Impaired hepatic function reduces drug clearance, leading to accumulation and potential toxicity.

Correct Answer is C

Explanation

A. Decreased GFR (glomerular filtration rate): A low GFR would reduce urine output, not increase it.

B. Over secretion of aldosterone: Aldosterone promotes sodium and water reabsorption, which decreases urine output.

C. Decrease amounts of ADH: Antidiuretic hormone (ADH) helps retain water. A deficiency leads to diuresis, causing polyuria (as seen in diabetes insipidus).

D. Activation of angiotensinogen: This leads to vasoconstriction and aldosterone release, promoting water retention, not polyuria.

A. “This test will inform your provider if you are anemic.” B. “This test will inform your provider if you have a thyroid disorder.” C. “This test will inform your provider if you have an infection.” D. “This test will inform your provider how your kidneys are functioning.”

Correct Answer is D

Explanation

A. “This test will inform your provider if you are anemic.” Hemoglobin and hematocrit levels are used to assess anemia, not creatinine.

B. “This test will inform your provider if you have a thyroid disorder.” TSH and T3/T4 levels assess thyroid function, not creatinine.

C. “This test will inform your provider if you have an infection.” Infection is usually assessed by WBC count, CRP, or cultures, not creatinine.

D. “This test will inform your provider how your kidneys are functioning.” Serum creatinine is a reliable indicator of renal function; it reflects the kidney’s ability to clear waste.
