A client is to receive a continuous Heparin infusion at s00 units per hour. Pharmacy supplies Heparin in a concentration of 25,000 units per 250mL of NSS.
Calculate the rate at which the nurse should set the infusion pump.
The Correct Answer is ["5"]
Step 1: Determine the concentration of Heparin in units per mL. 25,000 units ÷ 250 mL = 100 units per mL Result: 100
Step 2: Determine the rate in mL per hour needed to deliver 500 units per hour. 500 units ÷ 100 units per mL = 5 mL per hour Result: 5 mL per hour
The nurse should set the infusion pump to deliver at a rate of 5 mL per hour.

Correct Answer is C
Explanation
The correct answer is c. Replace fluids.
Choice A Reason: Apply restraints
Applying restraints is generally not the first-line intervention for managing alcohol withdrawal. Restraints should only be used if the patient poses an immediate threat to themselves or others and all other less restrictive measures have failed. The primary focus in the initial phase of alcohol withdrawal is to manage physiological stability and prevent complications.
Choice B Reason: Identify social supports
While identifying social supports is important for long-term recovery and overall mental health, it is not the highest priority during the initial phase of alcohol withdrawal. The immediate concern is to address the acute physiological symptoms and prevent severe complications such as seizures or delirium tremens.
Choice C Reason: Replace fluids
Replacing fluids is the highest priority in the initial phase of alcohol withdrawal. Dehydration is a common issue in patients undergoing withdrawal, and maintaining fluid balance is crucial for preventing complications. Ensuring adequate hydration helps stabilize the patient and supports overall physiological function during the withdrawal process.

Choice D Reason: Orient to reality
Orienting the patient to reality is important, especially if they are experiencing confusion or delirium. However, it is not the highest priority in the initial phase of alcohol withdrawal. The primary focus should be on stabilizing the patient’s physiological condition, including fluid replacement and monitoring vital signs.
Correct Answer is D
Explanation
d. Interview the client alone and assess for abuse
Explanation of Choices
Choice A Reason: Provide the Daughter and Client with Nutritional Counseling
While nutritional counseling is important, especially given the client’s malnourished state, it is not the immediate priority in this scenario. The client’s reluctance to speak and the daughter’s interruptions suggest that there may be underlying issues that need to be addressed first. Nutritional counseling can be provided later, once the immediate concerns have been resolved.
Choice B Reason: Request a Psychiatric Evaluation for the Client
Requesting a psychiatric evaluation may be necessary if there are signs of mental health issues, but it is not the first step in this situation. The priority is to ensure the client’s safety and well-being by addressing any immediate concerns, such as potential abuse. A psychiatric evaluation can be considered after the initial assessment and intervention.
Choice C Reason: Take the History from the Daughter Because of the Client’s Confusion
Taking the history from the daughter might seem practical due to the client’s confusion, but it is not the best approach in this case. The daughter’s constant interruptions and the client’s reluctance to speak raise concerns about the reliability of the information provided by the daughter. It is crucial to gather information directly from the client whenever possible to ensure an accurate assessment.
Choice D Reason: Interview the Client Alone and Assess for Abuse
Interviewing the client alone and assessing for abuse is the most appropriate intervention. The client’s reluctance to speak and the daughter’s interruptions could indicate that the client is being controlled or intimidated. Conducting a private interview allows the client to speak freely and provides an opportunity to identify any signs of abuse or neglect. Ensuring the client’s safety and addressing any immediate risks is the top priority.
