A client in DKA is ordered regular insulin at 7 units per hour for the current blood glucose level. The institution protocol is to add 100 units of regular insulin to a 150 ml bag of normal saline. What is the correct rate for the nurse to set the IV pump for this dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10.5"]
Step 1: Determine the concentration of insulin in the IV bag. 100 units of insulin are added to 150 mL of normal saline.
100 units ÷ 150 mL = (100 ÷ 150) = 0.6667 units per mL Result: 0.6667 units per mL
Step 2: Calculate the rate in mL per hour needed to deliver 7 units per hour. 7 units per hour ÷ 0.6667 units per mL = (7 ÷ 0.6667) = 10.5 mL per hour Result: 10.5 mL per hour
The correct rate for the nurse to set the IV pump is 10.5 mL per hour.

Correct Answer is A
Explanation
The correct answer is a. I feel so defeated and want to hide after I have binged.
Choice A Reason:
Individuals with binge-eating disorder often experience intense feelings of shame, guilt, and defeat after a binge episode. This emotional response is a hallmark of the disorder and can lead to further cycles of binge eating as a way to cope with these negative emotions. The statement “I feel so defeated and want to hide after I have binged” accurately reflects the emotional turmoil that accompanies binge-eating episodes.
Choice B Reason:
The statement “I am able to control the pace of my bingeing when I start getting full” is not typically associated with binge-eating disorder. People with this disorder often feel a loss of control over their eating during a binge episode and are unable to stop even when they are full. This lack of control is a key diagnostic criterion for binge-eating disorder.
Choice C Reason:
While feeling hungry can trigger a binge, it is not the primary characteristic of binge-eating disorder. The disorder is more about the uncontrollable nature of the eating episodes and the emotional distress that follows, rather than just responding to hunger. Therefore, the statement “My binges usually start off with feeling hungry” does not fully capture the essence of the disorder.
Choice D Reason:
Binge-eating as a reward for completing difficult tasks is not a typical feature of binge-eating disorder. The disorder is more about using food as a way to cope with negative emotions rather than as a reward. The statement “I binge to reward myself for completing difficult tasks” does not align with the common emotional triggers for binge-eating episodes.
Correct Answer is A
Explanation
Choice A Reason:
Strong negative feelings interfere with assessment and judgment.
This statement is the most accurate explanation for why a nurse needs to be aware of their own feelings while working with a family experiencing domestic violence. Negative emotions such as anger, frustration, or sadness can cloud a nurse’s judgment and hinder their ability to objectively assess the situation. These feelings can lead to biased decision-making, which may compromise the quality of care provided to the victim. For instance, a nurse who feels anger towards the abuser might unconsciously project these feelings onto the victim, affecting their ability to offer unbiased support and intervention. Therefore, maintaining emotional awareness is crucial for ensuring accurate assessments and effective interventions.
Choice B Reason:
Awareness protects one’s own mental health.
While it is true that being aware of one’s feelings can help protect a nurse’s mental health, this statement does not directly address the impact of these feelings on the assessment and judgment process. Emotional awareness is important for self-care and preventing burnout, but the primary rationale for emotional awareness in the context of domestic violence is to ensure that the nurse can provide objective and effective care. Therefore, this choice is not as relevant to the specific question as choice A.
Choice C Reason:
Positive feelings promote the development of sympathy for clients.
Positive feelings such as empathy and compassion are important in nursing, but they can also lead to over-identification with the client, which may result in blurred professional boundaries. While sympathy can foster a supportive relationship, it is essential for nurses to maintain a balance between empathy and professional detachment to provide objective care. This statement does not fully capture the importance of emotional awareness in preventing negative feelings from interfering with assessment and judgment.
Choice D Reason:
Strong positive feelings lead to underinvolvement with the victim.
This statement is less accurate because strong positive feelings, such as empathy and compassion, are more likely to lead to over-involvement rather than underinvolvement. Over-involvement can result in blurred boundaries and difficulty maintaining professional objectivity. However, the primary concern in the context of domestic violence is the interference of negative feelings with assessment and judgment, making this choice less relevant to the question.
