A nurse is developing a plan of care for a client who has Meniere’s disease. Which of the following medications should the nurse anticipate administering?

A. Respiratory rate of 12/min: A respiratory rate of 12/min is within the normal adult range (12-20 breaths per minute). In the context of increased intracranial pressure (ICP), respiratory rate changes might be noted as part of the Cushing's reflex (which is characterized by bradycardia, hypertension, and abnormal respiratory patterns like Cheyne-Stokes or ataxic breathing), but a rate of 12/min on its own is not indicative of a worsening condition. However, if the patient begins to show signs of irregular or abnormal breathing patterns, this would raise concern.

B. Blood pressure of 108/74 mm Hg: This blood pressure is also within the normal range and does not suggest a worsening of intracranial pressure. In fact, ICP can lead to a rise in blood pressure (due to the body's compensatory mechanisms, known as Cushing's triad), along with bradycardia and abnormal respirations. Thus, a stable blood pressure like 108/74 mm Hg is not concerning in this context.

C. Changes to pupil size and shape: Changes in pupil size, shape, or reactivity are significant indicators of worsening intracranial pressure. Unequal pupils (anisocoria), sluggish or absent response to light, and fixed dilated pupils are signs of brainstem compression or damage, which often occur as ICP increases. This could indicate herniation or severe brain injury, which are worsening conditions.

D. Swelling of the optic nerve: Swelling of the optic nerve, or papilledema, is another important sign of increased intracranial pressure. It occurs due to increased pressure within the skull, which causes congestion and swelling of the optic disc. This finding can be seen on fundoscopy and indicates a worsening condition, as it suggests elevated pressure affecting the brain.

E. Decreasing Glasgow Coma scores: A decreasing Glasgow Coma Scale (GCS) score is a critical indicator of worsening neurologic function in a patient with increased ICP. The GCS is used to assess a patient's level of consciousness, and a decreasing score suggests that the brain's function is deteriorating. This can be caused by worsening edema, brain herniation, or other severe neurological impairments associated with elevated ICP.

A. "Your heart condition is caused by excessive stretching of the ventricles": This statement is incorrect. Excessive stretching of the ventricles typically occurs in dilated cardiomyopathy, not restrictive cardiomyopathy (RCM). In RCM, the primary issue is not excessive stretching but rather stiffening of the ventricular walls.

B. "Your heart condition is caused from stiffening of the walls of the ventricles": This statement is correct. Restrictive cardiomyopathy (RCM) is characterized by abnormal stiffening (fibrosis) of the ventricular walls, which impairs the heart's ability to fill properly during the diastolic phase of the cardiac cycle. This stiffening restricts the heart's ability to relax and fill with blood efficiently.

C. "Your heart condition is caused by thickening of the ventricular walls and septum": This statement describes hypertrophic cardiomyopathy (HCM), not restrictive cardiomyopathy (RCM). In HCM, there is abnormal thickening of the ventricular walls and septum, leading to impaired filling of the ventricles and potential obstruction of blood flow out of the heart.

D. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty": This statement describes arrhythmogenic right ventricular cardiomyopathy (ARVC), not restrictive cardiomyopathy (RCM). ARVC is characterized by replacement of myocardial tissue with fibrous and fatty tissue, primarily affecting the right ventricle.
