A child with a heart defect is placed on a maintenance dose of Lanoxin elixir. The ordered dose is 0.07mg/kg/day in 2 divided doses. The child weighs 19 pounds. What is the maximum amount of medication that will be given per dose by the nurse?
The Correct Answer is ["0.3"]
Convert weight from pounds to kilograms:
19pounds÷2.2=8.64kg
Calculate the total daily dose:
0.07mg/kg/day×8.64kg=0.6048mg/day
Divide the daily dose into two doses:
0.6048mg/day÷2=0.3024mg/dose
Round off the dose to two decimal places:
0.3024mg≈0.30mg
The maximum amount of medication per dose is 0.3 mg.

Correct Answer is ["B","C","E"]
Explanation
A. Stand directly in front of the client when talking: Standing directly in front of an agitated client can be seen as confrontational and might escalate the situation. It is better to stand at an angle and maintain a non-threatening posture.
B. Avoid wearing necklaces during client care: Wearing necklaces or other loose accessories can pose a safety risk if a client becomes aggressive and tries to grab or pull them, potentially causing injury.
C. Provide immediate verbal feedback for escalating behavior: Immediate feedback can help de-escalate potentially aggressive behavior by addressing issues before they become more serious. It also reinforces appropriate behavior and sets clear boundaries.
D. Bring security with you for all client interactions: Bringing security for all interactions is impractical and can create an atmosphere of distrust. Security should be involved only when there is a credible risk of violence.
E. Review the layout of the facility: Understanding the layout of the facility, including exits and potential hazards, helps in planning for safe interactions and knowing escape routes if a situation escalates.
Correct Answer is ["B","E","F"]
Explanation
A. Circumoral cyanosis. This can occur but is less specific for PDA and more related to general issues with oxygenation.
B. Tachycardia. PDA can lead to increased heart rate as the heart works harder to manage the increased blood flow.
C. Elevated diastolic blood pressure. PDA usually causes a decrease in diastolic pressure, not an increase.
D. Bradycardia. Bradycardia is not typically associated with PDA.
E. Bounding peripheral pulses. PDA allows more blood to flow into the systemic circulation, leading to stronger pulses.
F. Continuous murmur. PDA typically causes a continuous "machine-like" murmur because of the continuous flow of blood from the aorta to the pulmonary artery.
G. Narrow pulse pressure. PDA often causes a wide pulse pressure, not a narrow one.
