ii. Criss-cross multiply the known numbers and divide this product by the remaining number to solve for X: 48 x 1 = 48 48/2.2 = 21.81 kg iii. Determine the client's total daily dosage when the doctor has ordered 5 mg/kg/day: 21.81 kg x 5 = 109.05 mg per day iv. Calculate the client's dose for each of the two divided doses: 109.05/2 = 54.53 mg, which is rounded off to 55 mg for each of the two divided doses. (See Pediatric Dosages and Special Considerations ) 28. The LPN collects this set of vital signs from the client: Pulse 67, Blood Pressure 167/89, Temperature 96.2 F, Pulse Ox 98%. What would be the most appropriate next action?

A.​ Apply a warm blanket. B.​ Administer Metoprolol. C.​ Contact the primary healthcare provider. D.​ Review the client’s chart. Correct Response: D

Explanation : The correct answer is (D) review the client's chart. The LPN should examine the client's chart to determine if the observed vital sign values, including a bradycardic pulse of 67, elevated blood pressure of 167/89, a low temperature of 96.2 F, and a Pulse Ox reading of 98%, align with the individual's baseline. If the client's baseline falls within the reported range, the high readings may not necessarily warrant immediate intervention, as they could reflect the client's normal physiological parameters. In this context, applying a warm blanket might address the low temperature but overlooks the broader picture of potential baseline variations. Administering Metoprolol without a comprehensive understanding of the client's baseline could risk exacerbating the bradycardia. While contacting the primary healthcare provider is a reasonable step, it should follow a thorough review of the client's chart to provide essential context for interpreting the observed vital sign values and ensuring an informed communication with the healthcare team. Therefore, the LPN's most appropriate next action is to review the client's chart, allowing for a more nuanced interpretation of the vital signs in the context of the client's individual baseline. (See Documentation and Reporting ) 29. Which of the following clients is at highest risk for an electrolyte imbalance? A.​ Six-month-old with diarrhea and a temperature of 101.5

B.​ 67-year-old recovering from hepatic injury C.​ 84-year-old admitted with a hip fracture D.​ 16-year-old with Type I diabetes Correct Response: A

Explanation : The correct answer is the six-month-old with diarrhea and a temperature of 101.5. Electrolyte imbalances are more likely in individuals with significant fluid losses, such as those experiencing diarrhea and fever. In this case, the six-month-old's condition increases the risk of dehydration, leading to potential electrolyte imbalances. Diarrhea results in the loss of essential
