RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
Correct Answer: A
Rationale: Standard heparin (IV) and low molecular weight heparin (LMWH, subcutaneous) are not interchangeable. Requesting standard heparin from the pharmacy ensures the correct medication and route, preventing dosing errors or inefficacy.
Question 2 of 5
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?
Correct Answer: C
Rationale: Dextroamphetamine-amphetamine, a stimulant, can cause insomnia if taken late. Determining dose timing identifies if adjusting to earlier administration reduces sleep issues. Bedtime routines, anxiety, or caffeine are secondary considerations.
Question 3 of 5
Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Correct Answer: C
Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after administration to prevent hypoglycemia. Synchronizing meal timing with insulin is critical. Glucose monitoring, hypoglycemia checks, and glucose sources are supportive but secondary.
Question 4 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 5 of 5
After receiving the third dose of a new oral anticoagulant prescription, an older adult client develops bleeding and tender gums and has many new bruises. Which actions should the nurse implement? Select all that apply.
Correct Answer: A,B,C,E
Rationale: Bleeding and bruising suggest anticoagulant-related complications. Completing a variance report documents potential issues, a soft toothbrush reduces gum trauma, reporting to the provider ensures intervention, and reviewing coagulation labs guides management. NSAIDs increase bleeding risk and are contraindicated.
