An elderly patient has bad hip surgery and will be receiving heparin, 4000 units subcutaneously every 12 hours. The heparin is available in vials of 5000 units/mL. Calculate how much heparin the nurse will administer for this dose.
The Correct Answer is ["0.8"]
To determine the correct volume to administer:
Volume to administer (mL) = Prescribed dose (units)/ Available concentration (units/mL)
= 4000 units/ 5000 units/mL
= 0.8 mL

Correct Answer is ["D","E"]
Explanation
A. While a nurse performing their duties is part of the context of care, it doesn't inherently establish negligence. Negligence occurs when that duty is not carried out appropriately or is breached. Simply performing a duty, even if an injury occurs, doesn't automatically equate to negligence. The focus is on how the duty was carried out.
B. This criterion relates to informed consent, which is a separate legal and ethical concept. While failure to obtain informed consent can lead to legal action (like battery), it is not a direct element required to prove negligence. Negligence focuses on the breach of a duty of care that leads to harm, regardless of whether consent was obtained.
C. For negligence to be established, there must be actual harm or injury to the patient. If no injury occurred, there is no basis for a negligence claim, even if a duty was breached. Damage is a crucial element of negligence.
D. A breach of duty means the nurse failed to act as a reasonably prudent nurse would have acted in the same or similar circumstances. This could involve an act of commission (doing something incorrectly) or an act of omission (failing to do something that should have been done).
E. The first element of negligence is establishing that a duty of care existed between the nurse and the patient. This means there was a professional relationship where the nurse had a responsibility to provide care to the patient. This duty arises from the nurse-patient relationship.
