The healthcare provider has prescribed heparin, 3 units/kg to be administered via IV push for a client who weighs 175 pounds. The vial is labeled as "100 units/mL." How many mL should the nurse administer? (Please enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.4"]
Step 1: Convert the weight from pounds to kilograms. We know that 1 kg = 2.2 lbs. So, the weight in kg is:
175 lbs ÷ 2.2 = 79.55 kg
Step 2: Calculate the total units of heparin needed. The prescription is for 3 units/kg, so:
3 units/kg × 79.55 kg = 238.65 units
Step 3: Calculate the volume of heparin to administer. The vial is labeled as "100 units/mL", so:
238.65 units ÷ 100 units/mL = 2.39 mL
So, the nurse should administer approximately 2.4 mL of heparin (rounded to the nearest tenth).

Correct Answer is B
Explanation
Choice A reason: A blood pressure of 130/80 mm Hg is considered high normal and may not require immediate follow-up for a patient with a history of hypertension.
Choice B reason: A serum creatinine of 1.6 mg/dL is above the normal range for both males and females, indicating possible kidney dysfunction, which requires further follow-up.
Choice C reason: Dark yellow urine could be a sign of dehydration, which is common in diabetes, but it is not as concerning as an elevated serum creatinine level.
Choice D reason: Difficulty staying asleep could be related to various factors and may require follow-up, but it is not as urgent as abnormal laboratory values.
Correct Answer is A
Explanation
Choice A reason: The immediate safety of the client is at risk. A person with dementia who is missing poses a potential danger to themselves due to confusion and the inability to navigate safely in their environment.
Choice B reason: While medication adherence is important for a client with schizophrenia, it does not present an immediate life-threatening situation. The nurse can return this call after addressing more urgent safety concerns.
Choice C reason: Physical altercations at school are serious, but if the child is safe and not in immediate danger, this call can be returned following more urgent issues.
Choice D reason: Sexual dysfunction can significantly affect quality of life, but it is not an immediate safety concern. This call should be returned after more urgent calls have been addressed.
