DHA Cardiac Interventional Radiography - Exam Topics Sample Questions

During a procedure, it is crucial to do which of the following?

Correct Answer:
monitor patient vital signs. 
during any medical procedure, especially invasive ones like cardiac radiography, it is paramount to monitor the patient's vital signs continuously. vital signs are indicators of the body’s essential functions and include the following parameters:

**temperature:** the body temperature can reveal the presence of an infection and the body's response to various physiological conditions. an abnormal temperature can be a critical signal requiring immediate medical attention.

**heart rate:** monitoring the heart rate is especially crucial during cardiac procedures. it provides information about the heart's condition and how well it is functioning under stress. any irregularities, such as bradycardia (slow heart rate) or tachycardia (fast heart rate), need to be addressed promptly to prevent complications.

**respiration:** the rate and depth of breathing are vital signs that indicate how well the patient is breathing. changes in respiration can signal distress or an adverse reaction during the procedure.

**blood pressure:** blood pressure measurements help assess the force of blood against the artery walls as the heart pumps. it is a critical indicator of cardiovascular health. extremely high or low blood pressure can lead to serious health issues, such as stroke or heart failure, and must be managed immediately to maintain patient safety.

monitoring these vital signs provides real-time data to healthcare providers, allowing them to detect any adverse changes in the patient's physiological state quickly. this monitoring is essential to intervene effectively and promptly, ensuring the patient's safety and the success of the procedure. the goal of keeping vital signs within normal ranges is to stabilize the patient and detect potential complications before they become life-threatening.

the importance of monitoring vital signs far outweighs other actions such as distracting the patient or administering pain medication at arbitrary intervals, which, while important for patient comfort, do not directly contribute to the critical assessment of the patient’s immediate physiological health. properly monitoring vital signs ensures that the healthcare providers are fully informed about the patient's condition at all times and can make informed decisions about their care.

To prove informed consent, a patient needs to do which of the following?

Correct Answer:
sign the consent form.
**to prove informed consent, a patient needs to do which of the following?**

**verbally consent.**

the option of verbally consenting, while it may be used in some cases, generally does not suffice when proving informed consent, especially for procedures that carry significant risks. informed consent involves not only agreeing to the procedure but also understanding the risks, benefits, alternatives, and potential outcomes associated with it. verbal consent might be difficult to verify later, as it does not provide a tangible record like a signed document.

**sign the consent form.** correct answer.

signing a consent form is the standard and most reliable method for proving informed consent. this process usually follows a detailed discussion between the healthcare provider and the patient, wherein the provider explains all pertinent information about the procedure. the signed document serves as a legal record that the patient has been informed and agrees to proceed with the understanding of the risks involved. in the context of high-risk procedures such as cardiac radiography, a signed consent form is crucial as it confirms the patient's acknowledgment and understanding of the risks explained by the physician.

**imply consent.**

implied consent is typically applicable in emergency situations where immediate action is required to save a life or prevent serious harm, and obtaining explicit consent is not feasible. however, for non-emergency procedures that involve significant risk, such as cardiac radiography, implied consent is not adequate. the law requires explicit informed consent to ensure that the patient is fully aware of what the procedure entails and the associated risks.

**comply with directions.**

compliance with medical directions or advice is part of following through with agreed medical care but does not equate to giving informed consent. informed consent must be explicitly given, usually in written form, particularly for procedures that involve significant risks. simply following directions without a formal process of informed consent does not meet the ethical or legal standards required, particularly for procedures that could have major impacts on a patient's health. in summary, for procedures that include inherent risks, such as cardiac radiography, the correct and ethical approach to proving informed consent is through obtaining a patient's signature on a consent form after a thorough discussion of all relevant information. this signed form is a vital legal document that serves to protect both the patient's rights and the healthcare provider's responsibilities.
