Correct Answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.

Correct Answer: B

Rationale: The correct answer is 'not pulling to a standing position.' If an 11-12-month-old child is unable to pull to a standing position, it can indicate a risk for developmental dysplasia of the hip. By 15 months of age, children should be walking, so delayed standing can be a red flag. The Trendelenburg sign is associated with gluteus medius muscle weakness, not hip dysplasia, making choice C incorrect. The Ortolani sign is used to detect congenital hip subluxation or dislocation, not developmental dysplasia, making choice D incorrect.

Correct Answer: D

Rationale: When evaluating a kinetic family drawing, noting the omission of any family members is an effective action. It is crucial to observe and analyze all aspects of the drawing, including what is missing. This can provide valuable insights into the child's perception and relationships within the family. Asking the child to draw their family doing something (Choice A) is more related to initial instruction rather than evaluation. Offering specific suggestions (Choice B) can influence the child's drawing and should be avoided to maintain the authenticity of the representation. Discouraging the child from talking about the drawing (Choice C) is counterproductive as verbal expression can provide additional context and understanding.

Correct Answer: C

Rationale: The LPN's statement about leaving the narcotics box unlocked after confirming the beginning of shift count was correct requires further investigation. Narcotics should be locked and kept in a secure place during the shift to prevent unauthorized access and ensure patient safety. This statement raises concerns about medication security, which is critical in preventing diversion and ensuring patient safety. The other statements demonstrate appropriate actions: A) The LPN acknowledges the need for a witness when wasting leftover narcotics, ensuring proper documentation and accountability during medication waste. B) Checking the facility's policy for proper disposal of controlled substances shows awareness of regulatory compliance regarding controlled substances. D) Recognizing an incorrect end-of-shift narcotics count and planning to report it reflects the LPN's responsibility in maintaining accurate records and addressing discrepancies, which is essential for medication safety and accountability.

Correct Answer: B

Rationale: A side effect of postpartum epidural morphine is the onset of itching within 3 hours of injection and lasting up to 10 hours. Nausea and vomiting might occur 4-7 hours after injection. While urinary retention is a side effect of postpartum epidural morphine, it is not typically assessed within the first 3 hours. Somnolence is a rare side effect and not commonly observed within the first 3 hours. Therefore, itching is the most likely side effect to be observed within the initial 3 hours after administering postpartum epidural morphine.
