The nurse is providing care for a patient with the following tracing on the electrocardiogram (ECG) for atrial fibrillation. What prescription should the nurse anticipate from the primary healthcare provider (PHCP)?

Choice A rationale
The apical pulse, also known as the point of maximal impulse (PMI), is located at the fifth intercostal space at the left midclavicular line. This is the location where the heartbeat is strongest and is the standard location for assessing the apical heart rate.
Choice B rationale
Placing the stethoscope directly over the heart on the sternum is not the standard method for assessing the apical heart rate. While the sternum is close to the heart, it is not the location where the heartbeat is strongest or most easily heard.
Choice C rationale
The right side at the midclavicular line, fourth intercostal space, is not the standard location for assessing the apical heart rate. The heart is located more towards the left side of the chest, and the apical pulse is typically not as easily heard on the right side.
Choice D rationale
The midaxillary line on the left side is not the standard location for assessing the apical heart rate. While this location is on the left side of the chest, it is not where the heartbeat is strongest or most easily heard.

Choice A rationale
Rheumatoid arthritis is an autoimmune disease that primarily affects the joints. While it can increase the risk of cardiovascular disease due to systemic inflammation, it is not typically considered a direct cause of secondary hypertension.
Choice B rationale
Coarctation of the aorta, a congenital condition characterized by a narrowing of the aorta, can cause secondary hypertension. This is because the narrowing can increase resistance to blood flow, leading to increased pressure.
Choice C rationale
Increased intracranial pressure (ICP) can cause secondary hypertension as part of Cushing’s reflex, a physiological response to protect the brain from damage. This reflex can lead to an increase in systemic blood pressure in an attempt to maintain cerebral perfusion.
Choice D rationale
Renal disease is a common cause of secondary hypertension. The kidneys play a crucial role in regulating blood pressure, and damage to the kidneys can lead to hypertension.
Choice E rationale
Colon cancer is not typically associated with secondary hypertension. While some cancers can produce substances that increase blood pressure, colon cancer is not commonly associated with this phenomenon.
