The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?
The Correct Answer is ["30"]
First, we need to find the concentration of insulin in the IV solution, which is the ratio of insulin units to saline volume. To do this, we use the given information that the IV solution contains 100 units in 250 ml. So, we divide 100 by 250 and get 0.4 units/ml.
Next, we need to calculate the infusion rate in ml/hour for the ordered dose of 12 units/hour. To do this, we use the ratio of insulin units to saline volume, which is 0.4 units/ml. So, we set up a proportion as follows:
0.4/1=12/x
To solve for x, we cross-multiply and get 0.4 x = 12. Then, we divide both sides by 0.4 and get x = 30. So, the infusion rate is 30 ml/hour.
Therefore, the nurse should program the infusion pump to deliver 30 ml/hour..

Correct Answer is C
Explanation
Choice A: Monitoring indwelling urinary catheter and measure strict intake and output is not an action that the nurse should immediately take, as this is not relevant or urgent for a client who may have had a stroke. This is a distractor choice.
Choice B: Keeping the bed in the lowest position and initiating seizure and fall precautions is not an action that the nurse should immediately take, as this is a preventive measure that does not address the acute problem of impaired cerebral perfusion. This is another distractor choice.
Choice C: Starting two large bore IV catheters and reviewing inclusion criteria for IV fibrinolytic therapy is an action that the nurse should immediately take, as this can prepare the client for potential administration of tissue plasminogen activator (tPA., which can dissolve blood clots and restore blood flow to the brain if given within 4.5 hours of stroke onset. Therefore, this is the correct choice.
Choice D: Maintaining elevated positioning of the dependent joints on affected side is not an action that the nurse should immediately take, as this can worsen edema and impair circulation in the affected limbs. The recommended position is to keep them at or below heart level. This is another distractor choice.
Correct Answer is B
Explanation
Choice A reason: A 16-year-old client diagnosed with major depression who refuses to participate in group does not require the nurse's immediate attention. Depression is a mood disorder that causes persistent feelings of sadness, hopelessness, and loss of interest. Refusing to participate in group may indicate low motivation, social withdrawal, or poor self-esteem, which are common symptoms of depression. The nurse should respect the client's preference and offer alternative activities or individual therapy.
Choice B reason:This client requires immediate intervention because pacing can be a sign of agitation, restlessness, or escalating mania. Clients with bipolar disorder in a manic phase may exhibit increased energy, impulsivity, irritability, and even aggression. If not addressed promptly, this behavior could escalate to disruptive outbursts, impulsive actions, or even violence toward themselves or others. The nurse should intervene by using calm communication, redirection, and possibly medication if prescribed to help de-escalate the situation and ensure safety.
Choice Creason:This scenario involves peer conflict, which is important to address, but it does not necessarily indicate an immediate risk of harm. Clients with antisocial behavior often engage in conflict due to manipulative or confrontational tendencies, but being yelled at does not mean they are in immediate danger. The nurse should monitor the situation and intervene to prevent escalation, but other safety concerns take priority.
Choice D reason: A 14-year-old client with anorexia nervosa who is refusing to eat the evening snack does not require the nurse's immediate attention. Anorexia nervosa is an eating disorder that causes extreme restriction of food intake and fear of weight gain. Refusing to eat the evening snack may indicate distorted body image, dietary rules, or anxiety, which are common factors of anorexia nervosa. The nurse should encourage the client to eat and provide support and education.
