A nurse is assessing a client who has restrictive cardiomyopathy (RCM). Which of the following statements should the nurse cue in the client?

Thickening of the walls of the ventricles.

Stretching of the ventricles.

Thickening of the ventricular walls and septum.

When the ventricular tissue becomes fibrous and fatty.

Answer and Explanation

The Correct Answer is D

Choice A reason:

Thickening of the walls of the ventricles is not typically associated with restrictive cardiomyopathy (RCM). This condition is more characteristic of hypertrophic cardiomyopathy (HCM), where the heart muscle becomes abnormally thick, making it harder for the heart to pump blood. In RCM, the walls of the ventricles are usually not thickened but become rigid due to fibrosis or infiltration, which restricts the heart’s ability to fill with blood during diastole.

Choice B reason:

Stretching of the ventricles is more commonly seen in dilated cardiomyopathy (DCM), not restrictive cardiomyopathy. In DCM, the heart’s ventricles become enlarged and weakened, which impairs the heart’s ability to pump blood efficiently. RCM, on the other hand, involves stiffening of the ventricular walls without significant dilation.

Choice C reason:

Thickening of the ventricular walls and septum is a hallmark of hypertrophic cardiomyopathy (HCM), not restrictive cardiomyopathy. In HCM, the thickened walls can obstruct blood flow and lead to various complications. RCM is characterized by the stiffening of the ventricular walls due to fibrosis or infiltration, which restricts diastolic filling.

Choice D reason:

When the ventricular tissue becomes fibrous and fatty is the correct description of restrictive cardiomyopathy (RCM). In RCM, the heart’s ventricles become stiff and less elastic due to fibrosis (scarring) or infiltration by abnormal substances, such as amyloid proteins. This rigidity impairs the heart’s ability to fill properly during diastole, leading to symptoms of heart failure

Correct Answer is A

Explanation

Choice A Reason:

The adrenal glands play a crucial role in responding to low blood glucose levels by releasing epinephrine (adrenaline) and norepinephrine. These hormones help to increase blood glucose levels by stimulating glycogenolysis (the breakdown of glycogen to glucose) and gluconeogenesis (the production of glucose from non-carbohydrate sources) in the liver. This response is part of the body’s fight-or-flight mechanism, which ensures that sufficient glucose is available for immediate energy needs.

Choice B Reason:

The liver does not release glucagon; rather, it responds to glucagon, which is released by the pancreas. Glucagon stimulates the liver to convert stored glycogen into glucose (glycogenolysis) and to produce glucose from non-carbohydrate sources (gluconeogenesis). This process helps to raise blood glucose levels when they are low.

Choice C Reason:

Glycogenesis is the process of converting glucose into glycogen for storage, and it occurs primarily in the liver and muscle cells, not in the pancreas. The pancreas releases insulin to promote glycogenesis when blood glucose levels are high, but it does not perform glycogenesis itself.

Choice D Reason:

The brain primarily uses glucose for energy and does not switch to using protein unless glucose levels are extremely low and prolonged. In such cases, the brain can use ketone bodies derived from fat as an alternative energy source. Protein is not a primary energy source for the brain under normal conditions.

A. Conivaptan hydrochloride 20 mg IV over 30 minutes STAT B. Vasopressin 10 mcg PO daily C. Sodium chloride tablets 1 g PO three times daily D. Tolvaptan 30 mg PO twice daily

Correct Answer is B

Explanation

Choice A Reason:

Conivaptan hydrochloride is a vasopressin receptor antagonist used to treat hyponatremia associated with SIADH. It works by blocking the action of ADH, thereby promoting water excretion without losing sodium. This medication is appropriate for managing SIADH.

Choice B Reason:

Vasopressin, also known as antidiuretic hormone (ADH), is not appropriate for a patient with SIADH. SIADH is characterized by excessive release of ADH, leading to water retention and hyponatremia. Administering vasopressin would exacerbate the condition by increasing water retention and further lowering sodium levels.

Choice C Reason:

Sodium chloride tablets are used to manage hyponatremia by increasing sodium levels in the blood. This treatment is appropriate for patients with SIADH to help correct the sodium imbalance caused by excessive ADH.

Choice D Reason:

Tolvaptan is another vasopressin receptor antagonist that is used to treat hyponatremia associated with SIADH. It helps to increase serum sodium levels by promoting water excretion while retaining sodium. This medication is suitable for managing SIADH.
