A patient with type 2 diabetes has a blood glucose of 58 mg/dL and is alert and oriented. What is the LPN's priority intervention?

The 15-15 rule directs giving 15–20 g of fast-acting carbohydrate to a conscious hypoglycemic patient, then rechecking glucose in 15 minutes.
While performing wound care, the LPN notes the wound base is covered with black, leathery tissue. This tissue is best described as:

A patient is admitted with acute asthma exacerbation. Which breath sound finding would the LPN expect to assess?

Bronchospasm during asthma causes diffuse expiratory wheezes due to narrowed airway lumen.
The LPN is preparing to administer insulin glargine. Which action is correct?
Answer: Inject it at the same time each day without mixing with other insulins
Glargine (Lantus) is a long-acting basal insulin given at a consistent time daily and must never be mixed with other insulins as it alters its pH-dependent action.
An LPN is caring for a postoperative patient who reports chest pain and shortness of breath 48 hours after hip surgery. Which condition should the LPN suspect first?
Answer: Pulmonary embolism
Sudden onset of chest pain and dyspnea in a postoperative orthopedic patient strongly suggests pulmonary embolism due to venous thromboembolism risk.
When caring for a patient with a chest tube connected to water-seal drainage, the LPN notes continuous bubbling in the water-seal chamber. What does this most likely indicate?
Answer: An air leak in the system or lung
Continuous bubbling in the water-seal chamber indicates an air leak, either from the patient's lung or a break in the system.
