A nurse admits a client who has a subarachnoid hemorrhage and increased intracranial pressure (ICP). Which of the following medications should the nurse expect to administer to decrease ICP?

A. "The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina": This statement is inaccurate. While angina can result from poor perfusion to the heart muscle, it is not typically due to weakening of the heart and coronary arteries. Angina often occurs due to coronary artery narrowing or blockage, leading to reduced blood flow and oxygen delivery to the myocardium.

B. "Coronary arteries become more elastic causing the arteries to stretch as individuals age causing the heart not to receive enough oxygen": This statement is incorrect. Coronary arteries do not become more elastic with age; in fact, they tend to become less elastic due to the development of atherosclerosis, which leads to arterial stiffening and decreased compliance. Atherosclerosis can cause narrowing or occlusion of the coronary arteries, resulting in reduced oxygen delivery to the heart muscle.

C. "Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure": This statement is partially incorrect. While it accurately describes the consequences of coronary artery narrowing (decrease in diameter) leading to insufficient blood, oxygen, and nutrient delivery to the heart muscle, the second part of the statement regarding dilation of coronary arteries with increased blood flow causing increased pressure is inaccurate. Coronary artery dilation is a compensatory response to increased demand for oxygen, aiming to improve blood flow to the myocardium. However, dilation alone does not increase pressure in the coronary arteries.

D. "Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle": This statement is accurate. Coronary artery disease (CAD) involves the progressive narrowing of the coronary arteries due to atherosclerosis, which reduces blood flow to the myocardium. As the arteries narrow, there is insufficient blood, oxygen, and nutrients reaching the heart muscle, leading to manifestations such as angina, myocardial ischemia, and potentially myocardial infarction.

A. Myopia: Myopia refers to nearsightedness, which is caused by refractive errors in the eye and is not associated with Meniere's disease. Myopia results in difficulty seeing distant objects clearly.

B. Vertigo: Vertigo is a hallmark symptom of Meniere's disease and is caused by an excessive accumulation of endolymph fluid in the inner ear. Vertigo presents as a sensation of spinning or dizziness, often accompanied by nausea, vomiting, and imbalance.

C. Photophobia: Photophobia refers to sensitivity to light, which can be associated with various eye conditions but is not a typical manifestation of Meniere's disease. Photophobia may occur in conditions such as migraine headaches or certain eye infections.

D. Presbycusis: Presbycusis refers to age-related hearing loss, which typically occurs gradually over time and is not directly associated with Meniere's disease. Meniere's disease is characterized by sudden episodes of vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in the ear.
