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
Explanation
Choice A reason: When the client has ankle edema, it is important for the nurse to assess for other signs of fluid retention, such as weight gain, jugular venous distension, and crackles in the lungs. However, ankle edema alone is not a specific indicator of preeclampsia or eclampsia, which are conditions that can cause hyperreflexia or increased DTRs.
Choice C reason: During admission to labor and delivery, it is important for the nurse to assess various aspects of the client's health status, such as vital signs, fetal heart rate, contractions, cervical dilation, and pain level. However, assessing DTRs is not a routine part of labor and delivery assessment unless there are signs of preeclampsia or eclampsia.
Choice D reason: Within the first trimester of pregnancy, it is important for the nurse to assess for signs of pregnancy-related nausea and vomiting, bleeding, infection, and ectopic pregnancy. However, assessing DTRs is not a routine part of first trimester assessment unless there are signs of neurological disorders or spinal cord injury.
Correct Answer is C
Explanation
Choice C is correct because repositioning the infant every 2 hours can help expose different parts of the skin to the phototherapy light and increase the effectiveness of the treatment. The nurse should also check the skin for signs of irritation or burns.
Choice A is incorrect because feeding the infant every 4 hours is not specific to home phototherapy. The infant may need more frequent feedings depending on their hunger cues and weight gain.
Choice B is incorrect because performing diaper changes under the light is not necessary and may expose the infant's genitals to excessive light and heat. The nurse should advise the parents to cover the infant's eyes and genitals with protective shields during phototherapy.
Choice D is incorrect because covering the infant with a receiving blanket can reduce the exposure of the skin to the phototherapy light and decrease the effectiveness of the treatment. The nurse should advise the parents to keep the infant unclothed or only in a diaper during phototherapy.
