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: B
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 with allergic rhinitis is taking the over-the-counter antihistamine diphenhydramine HCL. Which instruction is most important for the nurse to provide this client?
Correct Answer: C
Rationale: Diphenhydramine causes significant drowsiness, posing a safety risk for driving. Avoiding driving is critical to prevent accidents. Dosing frequency (every 4-6 hours, not 8), gastric upset (minimal), and dry mouth are less urgent concerns.
Question 3 of 5
A client with chemotherapy-induced nausea receives a prescription for metoclopramide. Which adverse effect is most important for the nurse to report?
Correct Answer: C
Rationale: Involuntary movements may indicate extrapyramidal side effects like tardive dyskinesia, a serious, potentially irreversible metoclopramide complication, requiring immediate reporting. Diarrhea, irritability, or nausea are less urgent, with nausea being the treated symptom.
Question 4 of 5
The nurse is providing discharge instructions to a client who has been prescribed gabapentin 300 mg by mouth (PO) three times a day for postherpetic neuralgia. Which symptom should the nurse tell the client to report to the healthcare provider?
Correct Answer: B
Rationale: Rapid weight gain may indicate fluid retention or other complications, requiring provider evaluation, though not a common gabapentin side effect. Gastric irritation, sexual dysfunction, and photosensitivity are less associated with gabapentin and less urgent.
Question 5 of 5
A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
Correct Answer: B
Rationale: Scopolamine prevents postoperative nausea, not pain. Explaining its purpose clarifies the client’s misunderstanding. Placement checks, expired effects, or new patches do not address the pain, which requires separate analgesia.
