Which assessment finding indicates that the patient is at high risk for development of pulmonary embolism?

Choice A rationale:

Incorrect because swallowing the tablet with water would lead to slower absorption and a delayed onset of action. Nitroglycerin is rapidly absorbed through the oral mucosa, and swallowing it would route it through the digestive system, where it would be absorbed more slowly and less effectively.

Swallowing the tablet could also increase the risk of side effects, such as headache and flushing, due to the larger amount of the drug that would be absorbed systemically.

Choice B rationale:

Incorrect because crushing the tablet and dissolving it in water would also delay its absorption. This method would require the tablet to dissolve in the water before it could be absorbed through the oral mucosa, which would slow down the onset of action.

Crushing the tablet could also damage the medication and make it less effective.

Choice C rationale:

Incorrect because placing the tablet in the patient's mouth next to the cheek would not allow for optimal absorption. The oral mucosa under the tongue is more permeable than the cheek, so placing the tablet under the tongue allows for faster and more efficient absorption.

Placing the tablet in the cheek could also increase the risk of the patient accidentally swallowing it.

Choice D rationale:

Correct because placing the tablet under the patient's tongue allows for rapid absorption and a quick onset of action. The sublingual route is the preferred method of administration for nitroglycerin because it allows the medication to bypass the digestive system and be absorbed directly into the bloodstream.

This method also allows for the patient to easily remove the tablet if they experience any side effects.

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.
