The patient is admitted to the cardiac unit.
Everyone admitted to the cardiac unit will have an EKG done unless otherwise ordered. This is an example of which type of order?
STAT
prn
One-time
Standing
The Correct Answer is D
Choice A rationale:
STAT orders are urgent and require immediate action. They are typically used for life-threatening situations or when a rapid response is needed to prevent serious harm. In this case, an EKG is important for patients admitted to the cardiac unit, but it is not necessarily an urgent procedure that requires immediate action in all cases.
STAT orders are often given verbally or over the phone, and they are typically written in all capital letters with the word "STAT" prominently displayed.
Examples of STAT orders include medications for cardiac arrest, intubation for respiratory distress, or emergency surgery for a ruptured appendix.
Choice B rationale:
PRN orders are "as needed" orders, meaning they are only carried out when a specific condition or symptom arises. They are not routinely implemented for all patients in a particular unit or setting.
PRN orders allow for flexibility in treatment plans and can help to manage pain, nausea, anxiety, or other symptoms that may fluctuate over time.
Examples of PRN orders include pain medication, anti-nausea medication, or sedatives.
Choice C rationale:
One-time orders are administered only once and are not repeated. They are often used for procedures, diagnostic tests, or medications that are not required on an ongoing basis.
In this case, an EKG is typically a one-time order for patients outside of the cardiac unit, but it becomes a standing order for patients admitted to the cardiac unit due to the increased importance of cardiac monitoring in this setting.
Examples of one-time orders include a chest X-ray, a blood draw, or a dose of antibiotics.
Choice D rationale:
Standing orders are routine orders that are implemented for all patients in a particular unit or setting, unless otherwise specified. They are designed to provide consistent and standardized care, and they often reflect best practices or guidelines for a specific patient population.
Standing orders can help to streamline care processes, reduce the need for individual orders, and ensure that patients receive necessary treatments or interventions without delay.
In this case, the standing order for an EKG upon admission to the cardiac unit ensures that all patients receive this important cardiac assessment, even if the ordering provider does not specifically write an order for it.
Other examples of standing orders in a cardiac unit might include daily weights, regular vital sign checks, or administration of cardiac medications.

Correct Answer is ["A","B","C","F","G"]
Explanation
Rationale for each choice:
Choice A: Hypovolemia
Impaired perfusion: Hypovolemia, or a decrease in circulating blood volume, leads to reduced blood flow to the wound site. This means that less oxygen and nutrients are delivered to the tissues, which are essential for healing processes like cell growth and collagen synthesis.
Impaired oxygen delivery: Oxygen is crucial for white blood cells to fight infection and for fibroblasts to create new tissue. Hypovolemia can significantly hinder wound healing by reducing oxygen availability at the wound site.
Delayed inflammatory response: The inflammatory phase of wound healing relies on adequate blood flow to deliver immune cells and initiate tissue repair. Hypovolemia can delay this response, leading to prolonged inflammation and delayed healing.
Decreased fibroblast activity: Fibroblasts, the cells responsible for collagen production, require oxygen and nutrients to function effectively. Hypovolemia can impair fibroblast activity, leading to reduced collagen synthesis and delayed wound closure.
Choice B: Poorly controlled blood glucose levels
Impaired immune function: High blood glucose levels impair the function of white blood cells, making the body more susceptible to infections. Infections at the wound site can significantly delay healing.
Impaired collagen synthesis: Hyperglycemia can also impair collagen synthesis, which is essential for wound strength and closure.
Vascular damage: Chronically high blood glucose levels can damage blood vessels, leading to impaired blood flow and oxygen delivery to the wound site, further hindering healing.
Choice C: Protein deficiency
Impaired collagen synthesis: Protein is a crucial building block for collagen, the main structural protein in connective tissue. A lack of protein can lead to reduced collagen production, resulting in delayed wound healing and weaker scar tissue.
Impaired immune function: Protein is also essential for immune cell function. A deficiency can impair the body's ability to fight infections, increasing the risk of wound complications.
Choice D: Adequate hydration
Incorrect: Staying well-hydrated supports the body’s healing process by ensuring proper blood flow and nutrient transport, thus it does not impede wound healing.
Choice E: Routine ambulation
Incorrect: Early ambulation after surgery promotes healing by improving circulation and reducing the risk of complications like blood clots, making it beneficial rather than harmful.
Choice F: Steroid therapy
Immunosuppressive effects: Steroids suppress the immune system, making the body less able to fight infections and hindering the inflammatory phase of wound healing.
Decreased collagen synthesis: Steroids can also decrease collagen synthesis, leading to weaker wound tissue and delayed closure.
Choice G: Obesity
Impaired blood flow: Excess adipose tissue can compress blood vessels, reducing blood flow to the wound site and impairing oxygen and nutrient delivery.
Increased inflammation: Adipose tissue produces inflammatory cytokines, which can prolong the inflammatory phase of wound healing and delay tissue repair.
Higher risk of infection: The folds of skin in obese individuals can create moist environments that are more prone to bacterial growth and infection.
Choice H: Vitamin C supplementation
Incorrect: Vitamin C plays a key role in collagen formation and tissue repair, so it supports rather than hinders wound healing.
