RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
A female client starts a new prescription, oxybutynin, for symptoms of an overactive bladder. The client tells the nurse that she is training to run a half-marathon. Which Instruction should the nurse emphasize?
Correct Answer: D
Rationale: Oxybutynin’s anticholinergic effects reduce sweating, increasing dehydration and overheating risks during marathon training. Emphasizing hydration and heat precautions is critical. Bruising, infections, or sun injury are less relevant concerns.
Question 2 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 pg/dL (6 to 47 μmol/dL)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
Question 3 of 5
A client with chronic lower back pain has been taking ibuprofen PO twice a day for several months. Which assessment is most important for the nurse to complete?
Correct Answer: A
Rationale: Long-term ibuprofen use risks gastrointestinal bleeding or ulcers. Assessing for abdominal pain detects these serious side effects. Pulse volume, pain levels, or sleep patterns are less critical to NSAID-related complications.
Question 4 of 5
A female client starts a new prescription, oxybutynin, for symptoms of an overactive bladder. The client tells the nurse that she is training to run a half-marathon. Which Instruction should the nurse emphasize?
Correct Answer: D
Rationale: Oxybutynin’s anticholinergic effects reduce sweating, increasing dehydration and overheating risks during marathon training. Emphasizing hydration and heat precautions is critical. Bruising, infections, or sun injury are less relevant concerns.
Question 5 of 5
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Reference Range: Hemoglobin (Hgb) [14 to 18 g/dL (8.7 to 11.2 mmol/L)]
Correct Answer: C
Rationale: Epoetin alfa stimulates red blood cell production, directly increasing hemoglobin levels. A rise to 12 g/dL, though below the male reference range, objectively indicates effectiveness in treating anemia. Iron therapy tolerance, subjective energy improvements, or dietary changes are less direct measures of epoetin’s impact.
