In addition to assessing peripheral pulses and auscultating the patient’s heart and lung sounds, which action will be implemented by the nurse before a cardiac catheterization? Select all that apply. One, some, or all responses may be correct.

Choice A Reason:

Cool, clammy skin is a common symptom in patients with atrial fibrillation, especially when the heart rate is very high. This symptom occurs due to decreased cardiac output, which leads to poor perfusion of the skin. When the heart is beating too fast, it doesn’t have enough time to fill properly, resulting in less blood being pumped out to the body. This can cause the skin to feel cool and clammy as the body tries to compensate for the reduced blood flow.

Choice B Reason:

Respiratory rate of 20 is within the normal range for adults, which is typically 12-20 breaths per minute. While it is important to monitor respiratory rate in patients with atrial fibrillation, a rate of 20 does not indicate any immediate distress or abnormality. Therefore, this choice is not particularly relevant to the assessment of a patient with a heart rate of 143 beats/min due to atrial fibrillation.

Choice C Reason:

Flushing of the skin is not a typical symptom associated with atrial fibrillation. Flushing can occur due to various reasons such as fever, anxiety, or certain medications, but it is not directly linked to the high heart rate or the irregular rhythm seen in atrial fibrillation. Therefore, this choice is not applicable in this context.

Choice D Reason:

Hypotension (low blood pressure) is a significant concern in patients with atrial fibrillation, especially when the heart rate is very high. The rapid heart rate can lead to decreased cardiac output, as the heart does not have enough time to fill properly between beats. This can result in lower blood pressure, which can cause symptoms such as dizziness, fainting, and fatigue. Monitoring blood pressure is crucial in managing patients with atrial fibrillation to prevent complications.

Choice E Reason:

Chest discomfort is a common symptom in patients with atrial fibrillation, particularly when the heart rate is very high. The irregular and rapid heart rate can cause the heart to work harder, leading to increased oxygen demand and potentially reduced oxygen supply to the heart muscle. This imbalance can result in chest pain or discomfort, which is a warning sign that the heart is under stress. It is important to assess and address chest discomfort promptly to prevent further cardiac complications.

Choice A Reason:

A 42-year-old man with gastroesophageal reflux disease (GERD) is not at the highest risk for obstructive sleep apnea (OSA). While GERD can be associated with OSA, it is not a primary risk factor. The main risk factors for OSA include obesity, age, and anatomical features that can obstruct the airway. Therefore, this individual is not at the greatest risk compared to others.

Choice B Reason:

A 55-year-old woman who is 50 lb (23 kg) overweight is at significant risk for developing OSA. Obesity is one of the most critical risk factors for OSA because excess weight can lead to fat deposits around the upper airway, which can obstruct breathing during sleep. Additionally, being overweight increases the likelihood of other conditions that can exacerbate OSA, such as hypertension and metabolic syndrome.

Choice C Reason:

A 20-year-old woman who is 8 months pregnant may experience temporary sleep disturbances, including snoring and mild sleep apnea, due to hormonal changes and increased abdominal pressure. However, pregnancy-related sleep apnea is usually transient and resolves after childbirth. Therefore, while she may have an increased risk during pregnancy, it is not as significant as the risk posed by obesity.

Choice D Reason:

A 73-year-old man with type 2 diabetes mellitus has an increased risk of OSA, as diabetes is associated with obesity and metabolic syndrome, which are risk factors for OSA. However, the presence of diabetes alone does not pose as high a risk as obesity. Therefore, while this individual is at risk, it is not as high as the risk associated with being significantly overweight.
