Priority Decision: While teaching women about the risks and incidence of CAD, what does the nurse emphasize?

Correct Answer: D

Rationale: In teaching women about risks and incidence of Coronary Artery Disease (CAD), emphasizing that CAD is the leading cause of death in women, with a higher mortality rate after myocardial infarction (MI) than in men (Option D) is crucial. This information is vital as CAD is often underestimated in women leading to delayed diagnosis and treatment. By highlighting this fact, nurses can empower women to take preventive measures and seek timely medical attention. Option A is incorrect because smoking is a significant risk factor for CAD in both men and women. Option B is incorrect as studies show that women tend to delay seeking treatment for CAD due to atypical symptoms. Option C is incorrect as recent research has shown that estrogen replacement therapy in postmenopausal women may not reduce the risk of CAD and can even have adverse effects. Educationally, understanding these nuances is essential for nurses to provide accurate and up-to-date information to their patients. By emphasizing the unique aspects of CAD in women, nurses can contribute to better outcomes through early detection, prevention, and treatment strategies tailored to women's specific needs.

Correct Answer: A

Rationale: In cardiac rehabilitation, patient safety is paramount. The correct answer is A) Pain or dyspnea develop. This is because experiencing chest pain or shortness of breath during exercise could indicate cardiac distress or inadequate oxygen supply to the heart muscle, necessitating immediate cessation of activity to prevent potential cardiac events. Option B) The HR exceeds 150 bpm is incorrect because heart rate alone may not always be a reliable indicator of exercise tolerance, especially in individuals with varying fitness levels or on medications affecting heart rate. Option C) The respiratory rate increases to 30 is incorrect because an increased respiratory rate may be a normal response to exercise and does not necessarily indicate a need to stop exercising unless accompanied by other symptoms. Option D) The HR is 30 bpm over the resting HR is incorrect because some individuals may have a naturally high resting heart rate or may be on medications that affect heart rate, making this guideline too general and not individualized. Educationally, understanding these nuances is crucial for healthcare providers working with cardiac patients to ensure safe and effective rehabilitation programs tailored to each patient's specific needs and limitations. It highlights the importance of monitoring multiple parameters during exercise and responding appropriately to signs and symptoms of cardiac distress to prevent adverse events during rehabilitation.

Correct Answer: C

Rationale: The correct answer is C) Both A and B, which includes Controlled Mechanical Ventilation (CMV) and Assist-Control Mode. In educational context, understanding the different modes of ventilator settings is crucial in managing patients with respiratory issues, especially in critical care settings. Controlled Mechanical Ventilation (A) is a mode where the ventilator completely controls the patient's breathing pattern. It delivers a set tidal volume at a set rate, regardless of the patient's own respiratory efforts. This mode is typically used for patients who are unable to initiate a breath on their own. Assist-Control Mode (B), on the other hand, allows the patient to trigger the ventilator to deliver a breath. The ventilator delivers a set tidal volume whenever the patient initiates a breath, but will also provide breaths at a set rate if the patient does not trigger the ventilator. This mode is more patient-friendly as it allows for some level of patient control over their breathing. Option D (None of the above) is incorrect as both A and B are valid modes of ventilation commonly used in clinical practice. Understanding the differences between these modes is essential for healthcare providers to effectively manage ventilation strategies based on individual patient needs. In summary, a comprehensive knowledge of the various modes of ventilation is vital for healthcare professionals working with patients requiring respiratory support. This knowledge ensures safe and effective management of ventilation, tailored to each patient's condition and respiratory needs.

Correct Answer: A

Rationale: The best approach in planning to meet Mr. Ross's nutritional needs, as he experiences nausea and vomiting due to large-volume irradiation to his thoracic region, is option A) Plan for frequent small meals of palatable foods. This option is correct because frequent small meals can help alleviate nausea and vomiting by reducing the volume of food in the stomach at one time, making it easier to digest. Palatable foods are also more likely to be tolerated when someone is experiencing these symptoms. Option B) Offer Mr. Ross three balanced meals a day is not the best choice because large meals can trigger or worsen nausea and vomiting in individuals undergoing radiation treatment. Option C) Determine Mr. Ross' caloric needs is not the immediate priority when someone is experiencing nausea and vomiting. The focus should be on providing small, easily digestible meals to prevent further discomfort. Option D) Ask the physician to prescribe an oral antiemetic for p.r.n. use is not the best initial approach because medication should be considered if non-pharmacological strategies, like dietary modifications, are ineffective or insufficient in managing the symptoms. In an educational context, it is crucial for healthcare providers to understand the impact of radiation therapy on the gastrointestinal system and how to tailor nutritional interventions to manage side effects like nausea and vomiting. By choosing the appropriate meal planning strategies, healthcare professionals can help improve the quality of life and nutritional status of patients undergoing treatment.

Correct Answer: A

Rationale: In this scenario, the correct answer is A) check her digitalis and potassium levels. Checking Dr. Baker's digitalis and potassium levels is crucial because chlorothiazide is a thiazide diuretic that can cause electrolyte imbalances, particularly hypokalemia. Hypokalemia can lead to symptoms such as loss of appetite and nausea, which Dr. Baker is experiencing. Monitoring these levels is essential to ensure her safety and well-being. Option B) obtaining a urine specimen is not the most appropriate action in this situation as it does not address the potential electrolyte imbalance caused by chlorothiazide. Option C) getting an electrocardiogram immediately is unnecessary and not indicated based on the symptoms described by Dr. Baker. Option D) reassuring Dr. Baker that her symptoms are to be expected is not appropriate without first investigating and addressing the possible electrolyte imbalance that could be causing her symptoms. In an educational context, understanding the side effects and potential complications of medications like chlorothiazide is crucial for healthcare professionals. This knowledge allows for timely intervention and appropriate monitoring to ensure patient safety and optimal outcomes. Monitoring electrolyte levels, especially potassium, is a common practice when administering diuretics to prevent adverse effects such as cardiac arrhythmias and other complications related to electrolyte imbalances.
