Extract:
Question 1 of 5
A patient refuses medication. Which is the nurse's first action?
Correct Answer: C
Rationale: Exploring with the patient the reasons for not wanting to take the medication is the appropriate first step. This approach allows the nurse to understand the patient's perspective, address any concerns or misconceptions.
Question 2 of 5
A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following examples should the nurse use to show appropriate transcription of this dosage?
Correct Answer: D
Rationale: Writing the dosage as 0.2 mg is the correct way to transcribe two tenths of a milligram. It uses a leading zero before the decimal point, which helps prevent dosage errors.
Question 3 of 5
A nurse is caring for a client with an elevated serum potassium level of 6.0 mEq/L (3.5-5.0 mEq/L). Which scheduled medication should the nurse plan to administer?
Correct Answer: D
Rationale: Sodium polystyrene sulfonate is a cation-exchange resin that is specifically used to treat hyperkalemia. It works by binding to potassium in the gastrointestinal tract, which is then excreted through the feces. This process effectively lowers serum potassium levels. Given its mechanism of action and its specific indication for treating hyperkalemia, sodium polystyrene sulfonate is the appropriate choice for a patient with an elevated potassium level of 6.0 mEq/L.
Question 4 of 5
A nurse caring for a client is receiving hydromorphone HCL via PCA pump and reports continuous pain of 6 on a scale from 0 to 10. Which of the following actions should the nurse take first?
Correct Answer: B
Rationale: Checking the display on the pump is the most critical initial action. This step ensures the PCA pump is functioning correctly and delivering the correct dosage as prescribed.
Question 5 of 5
A client presents to the clinic with intense itching at night and is diagnosed with Pinworms. The nurse anticipates the client would be placed on which medication to treat this condition?
Correct Answer: C
Rationale: Mebendazole (Vermox) is an anthelmintic medication specifically used to treat parasitic worm infections, including pinworms. It works by inhibiting the worms' ability to absorb glucose, leading to their death.
