The physician has ordered heparin 7000 units subcutaneous daily.

The medication is supplied in heparin 10,000 units in 1 mL. How many milliliters will the nurse administer?

Choice A rationale

While electronic medical record (EMR) systems aim to improve legibility by using standardized digital documentation, they do not entirely eliminate the need to interpret physician notes or other entries. There may still be instances where clarification or interpretation is required.

Choice B rationale

A significant benefit of implementing an EMR system is the potential to streamline documentation processes. Electronic charting can reduce the time nurses spend on manual tasks such as handwriting notes, transcribing orders, and locating paper records, thereby improving efficiency.

Choice C rationale

Password management and security protocols are often a necessary component of electronic systems to protect patient privacy and data integrity. Implementing a new EMR system may involve changes to password policies and frequency of updates, which could be a source of frustration rather than a benefit.

Choice D rationale

Access to a family member's medical record, even a child's, raises significant privacy and security concerns. Healthcare systems have strict regulations (e.g., HIPAA) to protect patient confidentiality, and nurses typically do not have unrestricted access to family members' records.

Choice A rationale

Lack of exercise primarily affects the cardiovascular and musculoskeletal systems and is not a direct cause of fluid volume deficit. While it can indirectly impact overall health, it doesn't typically lead to significant fluid loss.

Choice B rationale

Excessive food intake, especially if high in sodium, can actually lead to fluid volume excess rather than deficit due to osmotic shifts and water retention.

Choice C rationale

Bed rest can lead to some fluid redistribution within the body but does not directly cause a significant loss of total body fluid. Immobility can affect other physiological processes more directly.

Choice D rationale

Excessive gastrointestinal losses, such as vomiting, diarrhea, or drainage from nasogastric tubes or ostomies, directly remove significant amounts of fluid and electrolytes from the body, leading to fluid volume deficit.
