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 ["B","C","D","F"]
Explanation
Choice B is correct because sodium intake can be regulated by limiting canned foods in the diet. Canned foods often contain high amounts of sodium as a preservative, which can increase blood pressure and fluid retention. The nurse should advise the client to choose fresh or frozen foods instead of canned foods or rinse them before eating.
Choice C is correct because salt substitutes can help with maintaining a healthy diet by reducing sodium intake. Salt substitutes are products that contain potassium chloride or other ingredients that mimic the taste of salt but have less or no sodium. The nurse should advise the client to use salt substitutes sparingly and check with their healthcare provider before using them if they have kidney problems or take certain medications.
Choice D is correct because weight management is promoted by taking daily walks for thirty minutes. Being overweight or obese can increase blood pressure and strain the heart and blood vessels. The nurse should advise the client to lose weight or maintain a healthy weight by engaging in regular physical activity and eating a balanced diet.
Choice F is correct because uncontrolled hypertension can lead to renal damage. High blood pressure can damage the blood vessels in the kidneys and impair their function, leading to chronic kidney disease or failure. The nurse should advise the client to monitor their blood pressure regularly and take prescribed medications as directed.
Choice A is incorrect because alcohol consumption can produce vascular changes that increase blood pressure. Alcohol can cause vasodilation, which lowers blood pressure temporarily, but also stimulates the sympathetic nervous system, which raises blood pressure over time. The nurse should advise the client to limit alcohol intake to no more than one drink per day for women and two drinks per day for men.
Choice E is incorrect because blood pressure readings should not be taken at noontime. Blood pressure readings should be taken at the same time each day, preferably in the morning before breakfast or in the evening before dinner, when blood pressure is usually lower and more stable. The nurse should advise the client to avoid taking blood pressure readings when they are stressed, anxious, or have just exercised or eaten.
Correct Answer is A
Explanation
Choice A: This hernia is a normal variation that resolves without treatment is a correct explanation for the nurse to provide, as this refers to an umbilical hernia, which is a common and harmless condition in infants that usually disappears by age 2. Therefore, this is the correct choice.
Choice B: An abdominal binder can be worn daily to reduce the protrusion is not an appropriate explanation for the nurse to provide, as this is not an effective or recommended method to treat a hernia. This is a distractor choice.
Choice C: Restrictive clothing will be adequate to help the hernia go away is not a relevant explanation for the nurse to provide, as this does not affect the hernia or its resolution. This is another distractor choice.
Choice D: The quarter should be secured with an elastic bandage wrap is not a sensible explanation for the nurse to provide, as this is a folk remedy that has no scientific basis and can cause skin irritation and infection. This is another distractor choice.
