LPN Fundamentals of Nursing Quizlet

Correct Answer: C

Rationale: Crackles in the lungs are indicative of fluid accumulation in the alveoli, which is a characteristic finding in clients with fluid volume excess. The crackling sound occurs due to the presence of excess fluid in the lungs, impairing normal ventilation and gas exchange. Monitoring for crackles is essential for early detection and management of fluid overload in clients.

Correct Answer: A

Rationale: Monitoring gastric residuals every 4 hours is essential to assess the stomach's ability to empty properly, reducing the risk of aspiration. It helps in determining if the feedings are being tolerated by the client and if adjustments are needed in the feeding regimen. Positioning the client in a semi-Fowler's position helps prevent reflux and aspiration by promoting proper digestion and emptying of the stomach contents. Checking for tube placement by auscultating air after feeding confirms correct tube placement in the stomach. Warming the formula to body temperature before feeding enhances client comfort but does not directly prevent aspiration.

Correct Answer: C

Rationale: The ability to bear weight on both legs indicates muscle strength and stability necessary for ambulation. This skill is crucial for the client to support their body weight and move independently when standing or walking.

Correct Answer: A

Rationale: Lisinopril, an ACE inhibitor, can lead to hyperkalemia by reducing potassium excretion. Therefore, clients taking lisinopril should be advised to avoid foods high in potassium to prevent potential complications associated with elevated potassium levels.

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.
