- A. NPO diet
- B. Blood product administration

For care of a patient who has oral cancer, which task would be appropriate to delegate to the LPN/LVN?
- A. Assist the patient to brush and floss
- B. Explain when brushing and flossing are contraindicated
- C. Give antacids and sucralfate suspension as ordered
- D. Recommend saliva substitutes
Correct Answer: C
Rationale: LPN/LVNs excel in medication administration within their scope, making giving antacids and sucralfate ordered for oral cancer's mucosal protection ideal. Brushing and flossing assistance fits nursing assistants, a basic task. Explaining contraindications requires RN-level judgment to assess risks like bleeding or infection. Recommending saliva substitutes needs physician or pharmacist input, beyond LPN/LVN authority. Medication delivery leverages their training, easing symptoms like pain or ulcers, ensuring safe, supervised care in oral cancer's complex management, a practical delegation choice.

Officially approved blood glucose meters used for self-testing and point-of-care diagnostics are not always suitable to measure the blood glucose values in neonates. Question: What is the main cause for this?
- A. Some meters are calibrated to plasma glucose and other meters to blood glucose
- B. Some measurement methods are sensitive to high levels of ascorbic acid (vitamin C)
- C. The measurement variation of some meters is too large
- D. Some meters are sensitive to abnormal haematocrit values
Correct Answer: D
Rationale: Neonate glucose flubs haematocrit swings throw meters off, not calibration, vitamin C, or variance. Nurses adjust for this, a chronic baby glitch.
