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 B
Explanation
Choice A Reason: Prevents Extrapyramidal Side Effects
Extrapyramidal side effects (EPS) are drug-induced movement disorders that include symptoms such as tremors, rigidity, bradykinesia, and tardive dyskinesia. These side effects are commonly associated with first-generation antipsychotics. While second-generation antipsychotics like olanzapine have a lower risk of causing EPS, their primary use in this context is not to prevent these side effects. Therefore, this choice is not the most appropriate response to the family’s question.
Choice B Reason: Reduces Agitation Until the Lithium Takes Effect
Olanzapine is a second-generation antipsychotic that is effective in managing acute agitation and psychotic symptoms in patients with bipolar disorder. Lithium, while effective for long-term mood stabilization, takes several days to weeks to reach therapeutic levels and exert its full effect. During this period, olanzapine can help reduce the client’s agitation and stabilize their mood. This makes it the most appropriate response to the family’s question.
Choice C Reason: Cures Manic Symptoms
While olanzapine can help manage manic symptoms, it does not “cure” them. Bipolar disorder is a chronic condition that requires ongoing management with medications and therapy. The term “cure” is misleading as it implies a permanent resolution of symptoms, which is not the case with bipolar disorder. Therefore, this choice is not accurate.
Choice D Reason: Ensures High-Quality Sleep
Olanzapine can have sedative effects and may help improve sleep in some patients. However, its primary use in this scenario is to manage acute agitation and psychotic symptoms rather than to ensure high-quality sleep. While improved sleep may be a beneficial side effect, it is not the main reason for its prescription in this context.
Correct Answer is B
Explanation
Choice A Reason:
Promoting activities that encourage self-reflection. While promoting self-reflection is important in the therapeutic process, it is not the most essential aspect initially for establishing a trusting nurse-patient relationship. Self-reflection activities are more effective once a foundation of trust has been established.
Choice B Reason:
Conveying an accepting attitude. This statement is correct. Conveying an accepting attitude is crucial in the initial stages of establishing a trusting nurse-patient relationship. Patients with borderline personality disorder often feel judged and misunderstood. An accepting attitude helps to create a safe and supportive environment, which is essential for building trust and encouraging open communication.
Choice C Reason:
Identifying community resources. Identifying community resources is important for long-term support and management of borderline personality disorder, but it is not the most essential aspect initially for establishing trust. This step is more relevant once the therapeutic relationship has been established and the patient is ready to engage with external support systems.
Choice D Reason:
Providing positive feedback. Providing positive feedback is beneficial in reinforcing positive behaviors and encouraging progress. However, it is not the most essential aspect initially for establishing trust. Positive feedback is more effective when the patient already feels understood and supported by the nurse.
