LPN Fundamentals of Nursing Quizlet

Correct Answer: C

Rationale: Dry mucous membranes are a classic clinical manifestation of fluid volume deficit. Dehydration leads to reduced fluid intake or excessive fluid loss, resulting in decreased moisture in the mucous membranes. Bradycardia, increased skin turgor, and hypertension are not typically associated with fluid volume deficit. Bradycardia is more commonly seen in conditions like hypothyroidism or increased intracranial pressure. Increased skin turgor is a sign of dehydration, and hypertension is not a typical finding in fluid volume deficit.

Correct Answer: A

Rationale: When a client is on total parenteral nutrition (TPN), monitoring blood glucose levels daily is crucial to manage and detect complications like hyperglycemia, which can occur due to the high glucose content in TPN solutions. Regular blood glucose monitoring helps the healthcare team adjust the TPN infusion rate to maintain optimal glucose levels and prevent adverse events.

Correct Answer: C

Rationale: Dark-colored urine is a common sign of dehydration as the urine becomes concentrated. Dehydration leads to reduced fluid intake or excessive fluid loss, causing the urine to be darker in color due to increased urine concentration.

Correct Answer: A

Rationale: Shaking the inhaler before use is crucial to ensure proper mixing of the medication inside the inhaler. This action helps to disperse the medication evenly, allowing for consistent dosing during inhalation. Breathing out forcefully, taking the medication with food, and using a spacer are not related to the correct use of a metered-dose inhaler and may not lead to optimal medication delivery.

Correct Answer: B

Rationale: Flushing the feeding tube every 4 hours is essential to maintain patency and prevent clogging, ensuring the client receives the prescribed enteral nutrition without interruption. Monitoring intake and output, measuring temperature, and changing the feeding bag and tubing are also important aspects of care but not directly related to maintaining the patency of the feeding tube in a client receiving continuous enteral feedings.
