Which are therapeutic effects of acetaminophen? Select all that apply.
Antacid
Anti-inflammatory
Analgesic
Antidiarrheal
Antipyretic
Correct Answer : C,E
A. Antacid: Acetaminophen does not neutralize stomach acid or alter gastric pH. Antacid properties are unrelated to its mechanism of action, which is focused on central inhibition of prostaglandin synthesis rather than gastrointestinal acid modulation.
B. Anti-inflammatory: Unlike NSAIDs, acetaminophen has minimal to no peripheral anti-inflammatory effect. It primarily acts centrally in the CNS, reducing pain perception and fever without significant impact on inflammatory processes.
C. Analgesic: Acetaminophen provides pain relief by inhibiting central prostaglandin synthesis, which decreases the perception of pain. It is effective for mild to moderate pain, such as headaches, musculoskeletal pain, and postoperative discomfort.
D. Antidiarrheal: Acetaminophen does not affect gastrointestinal motility or secretions and therefore has no role in treating diarrhea. Its pharmacologic effects are limited to analgesia and fever reduction.
E. Antipyretic: Acetaminophen reduces fever by acting on the hypothalamic heat-regulating center, promoting vasodilation and sweating. This thermoregulatory effect helps lower elevated body temperature in febrile conditions.

Correct Answer is B
Explanation
A. Decreased serum potassium: Vasopressin does not significantly affect potassium levels. Changes in serum potassium are not used to evaluate the drug’s effectiveness in managing diabetes insipidus.
B. Increased urine serum osmolality: Diabetes insipidus causes excessive dilute urine due to insufficient antidiuretic hormone activity. Effective vasopressin administration promotes water reabsorption in the kidneys, concentrating the urine and increasing urine osmolality, which indicates therapeutic success.
C. Decreased blood pressure: Vasopressin can raise blood pressure through vasoconstriction, but a decrease in blood pressure would not indicate effectiveness in treating diabetes insipidus and may signal an adverse response or other condition.
D. Increased heart rate: Heart rate changes are not a reliable indicator of vasopressin effectiveness for diabetes insipidus. Therapeutic monitoring focuses on urine output and concentration rather than cardiovascular parameters.
Correct Answer is C
Explanation
A. "This drug should make me feel full.": Pioglitazone is a thiazolidinedione used to improve insulin sensitivity in type 2 diabetes. It does not act as an appetite suppressant, so expecting a feeling of fullness reflects a misunderstanding of its mechanism.
B. "This drug may cause flatulence.": While some medications for diabetes, such as alpha-glucosidase inhibitors, can cause flatulence, pioglitazone does not commonly produce this side effect. Expecting gas is not accurate for this drug.
C. "This drug can damage my liver.": Pioglitazone carries a risk of hepatotoxicity, so clients should be aware of signs of liver injury (e.g., jaundice, dark urine, fatigue). This statement demonstrates understanding of a key safety concern associated with the medication.
D. "This drug may cause weight loss.": Pioglitazone is more commonly associated with weight gain due to fluid retention rather than weight loss. Believing it promotes weight loss indicates a misconception about the drug’s effects.
