LPN Fundamentals of Nursing

Correct Answer: C

Rationale: To ensure effective drainage, the catheter should be inserted 2-4 inches into the urethra. This length allows the catheter to reach the bladder, bypass the urethral sphincters, and ensure proper drainage without causing discomfort or injury. Using sterile gloves, cleaning the catheter with alcohol, and performing the procedure every 8 hours are not accurate instructions for self-catheterization.

Correct Answer: A

Rationale: Encouraging the use of an incentive spirometer is crucial in preventing respiratory complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, which can prevent atelectasis (lung collapse) and promote lung expansion. This, in turn, reduces the risk of respiratory complications such as pneumonia. Restricting fluid intake, placing the client in a supine position, and administering a cough suppressant are not appropriate actions for preventing respiratory complications in a postoperative client.

Correct Answer: C

Rationale: The primary benefit of using electronic health records (EHRs) in healthcare is that they improve the accuracy and completeness of patient information. By utilizing EHRs, healthcare providers have access to more reliable and up-to-date patient data, which leads to better patient care outcomes. This improved accuracy enables healthcare professionals to make better-informed decisions and provide more effective treatments, ultimately enhancing patient safety and quality of care.

Correct Answer: D

Rationale: Having a second nurse witness the disposal of any unused portion of a controlled substance is a legal requirement to ensure proper disposal, prevent diversion, and maintain accountability. This practice helps in reducing the risk of misuse or unauthorized access to controlled substances, enhancing patient safety, and complying with legal regulations and standards.

Correct Answer: C

Rationale: Crackles in the lungs are a classic sign of fluid volume overload. When there is an excess of fluid in the lungs, it can manifest as crackling sounds upon auscultation. This finding indicates the accumulation of fluid in the alveoli and interstitial spaces of the lungs, which is a common manifestation of fluid volume overload.
