Canadian Cardiac Vascular Nursing - Exam Topics Sample Questions

With patients who receive implanted cardiac defibrillators, lifestyle modifications are a concern. Patients should be educated on avoiding all of the following sources of electromagnetic interference such as what?





Correct Answer:
running motors and alternators.
patients with implanted cardiac defibrillators (icds) need to be cautious of certain environmental factors that can interfere with the proper functioning of their device. one significant concern is electromagnetic interference (emi), which can be emitted by various sources.

emi can disrupt the functionality of icds, potentially leading to inappropriate shocks or failure to deliver necessary therapy when required. among the common sources of emi that patients need to avoid are running motors and alternators. these devices generate strong electromagnetic fields that can interfere with the operation of cardiac defibrillators. examples include large electric motors found in industrial environments and alternators in automotive engines.

patients may also have concerns about other common electronic devices such as microwaves, cell phones, computers, televisions, and fm radios. it is important to note that the impact of these devices varies: - **microwaves**: modern microwaves are generally well-shielded, and as long as the microwave is in good condition and used according to the manufacturer's instructions, it should not pose a significant risk of emi to icds. - **cell phones**: while older guidance often suggested keeping cell phones away from icds, advances in technology have reduced many of these risks. nevertheless, it is still advisable for patients to use their cell phones on the opposite side of their body from where their device is implanted to minimize any potential interference. - **computers and monitors**: normal use of computers and office equipment has not been shown to pose a significant risk to icd function at typical distances. - **televisions**: similar to computers, normal usage of modern televisions does not significantly risk interfering with icds. - **fm radios**: standard use of fm radios also does not typically emit enough emi to interfere with an icd.

ultimately, patients with icds should maintain a cautious approach around industrial equipment and environments where high-powered electrical devices are operational. consulting with a healthcare provider for personalized advice based on individual circumstances and types of devices encountered in daily life is recommended. this ensures both the safety and effectiveness of the cardiac defibrillator.

The nurse is assessing the medication history of an older adult with a cardiac history. Which of the following categories of medications should be assessed?





Correct Answer:
both a and b
when assessing the medication history of an older adult with a cardiac history, it's crucial for the nurse to gather comprehensive information about all the medications the patient is taking. this includes not only the medications prescribed by healthcare providers but also any over-the-counter (otc) medications, nutritional supplements, and vitamins the patient may be using. here's why each category is important:

**prescribed medications:** these are medications that have been recommended and prescribed by the patient's healthcare providers. for patients with a cardiac history, these could include drugs like beta-blockers, ace inhibitors, or anticoagulants, which are critical for managing their condition. understanding what prescribed medications the patient is taking helps in evaluating treatment effectiveness and safety, ensuring they are appropriate for the patient's current health status, and checking for potential drug interactions.

**over-the-counter medications:** these are drugs that can be purchased without a prescription, such as pain relievers (like acetaminophen or ibuprofen), antacids, laxatives, and cold medicines. many otc drugs can interact with prescription medications or exacerbate existing health conditions. for example, some otc medications may increase blood pressure or interfere with blood thinners, posing significant risks for cardiac patients.

**nutritional supplements:** supplements include products like fish oil, coenzyme q10, or magnesium, which some patients take to manage or prevent health issues. although they are not regulated as strictly as prescription or otc medications, their effects on health and interactions with other drugs can be substantial. for instance, supplements like fish oil may have blood-thinning effects, which is an important consideration for patients on anticoagulant therapy.

**vitamins:** while generally taken to support overall health, certain vitamins in high doses can impact health conditions and interact with medications. for example, vitamin k can counteract the efficacy of blood thinners, crucial for patients with cardiac conditions to avoid clotting disorders.

**assessment of compliance:** in addition to identifying the types of medications taken, it is equally important to assess whether the patient is compliant with their medication regimen. non-compliance can lead to suboptimal treatment outcomes and exacerbate health conditions. understanding barriers to compliance, such as side effects, cost of medications, or misunderstanding dosage instructions, can help the nurse provide better care and education to the patient.

the correct answer to the question is "both a and b," meaning that the nurse should assess both prescribed and over-the-counter medications, alongside nutritional supplements and vitamins. this thorough medication review helps ensure a holistic understanding of the patient's treatment plan, enhances patient safety, and optimizes therapeutic outcomes in managing their cardiac condition.
