RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
The nurse is caring for a client receiving a prescription for sucralfate to treat a peptic ulcer. Which instruction should the nurse provide during discharge education?
Correct Answer: C
Rationale: Sucralfate adheres to ulcer sites best on an empty stomach, taken 1 hour before meals, maximizing its protective effect. Missing a dose should not prompt doubling, and scheduling with meals or bedtime reduces efficacy due to food interference.
Question 2 of 5
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level [0.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Correct Answer: C
Rationale: Hypokalemia (3.2 mEq/L) increases digoxin toxicity risk, potentially causing arrhythmias. Immediate reporting allows potassium correction. Mild hyponatremia, normal creatinine, and therapeutic digoxin levels are less urgent.
Question 3 of 5
A glucagon emergency kit is prescribed for a client with type 1 diabetes mellitus. When should the nurse instruct the client and family that glucagon needs to be administered?
Correct Answer: C
Rationale: Glucagon raises blood glucose in severe hypoglycemia (e.g., unconsciousness), preventing complications. It’s not for hyperglycemia, sick days, or diabetic ketoacidosis, which require insulin and other treatments.
Question 4 of 5
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?
Correct Answer: D
Rationale: Adalimumab, an immunosuppressant, increases infection risk. Avoiding crowds and sick individuals minimizes exposure, protecting the client’s compromised immune system. Chest x-rays, vaccinations, or eye exams are not specifically required for adalimumab initiation.
Question 5 of 5
The nurse is caring for an adult client who is taking carbidopa-levodopa for Parkinson's disease. The client is concerned that the medication is not working. Which intervention should the nurse implement first?
Correct Answer: A
Rationale: Clarifying the client’s concern about carbidopa-levodopa’s effectiveness guides targeted assessment and intervention. Meal timing, dyskinesia, or urine color are secondary until the specific issue is understood.
