A nurse and a newly licensed nurse are providing care for a client who has distributive shock. How should the nurse explain the pathophysiology of distributive shock to the newly licensed nurse?

"Distributive shock occurs due to loss of myocardial contractility."

"Distributive shock occurs due to loss of blood volume."

"Distributive shock occurs due to systemic vasodilation."

"Distributive shock occurs due to increased systemic vascular resistance."

Answer and Explanation

The Correct Answer is C

A. "Distributive shock occurs due to loss of myocardial contractility": This statement is incorrect. Distributive shock is not primarily caused by loss of myocardial contractility. Instead, distributive shock is characterized by widespread vasodilation, which leads to inadequate tissue perfusion despite normal or high cardiac output.

B. "Distributive shock occurs due to loss of blood volume": This statement is inaccurate. Distributive shock is not primarily caused by loss of blood volume. While hypovolemia (loss of blood volume) can lead to shock, distributive shock specifically involves excessive vasodilation, resulting in a relative hypovolemia due to pooling of blood in the expanded vascular bed.

C. "Distributive shock occurs due to systemic vasodilation": This statement is correct. Distributive shock, also known as vasodilatory shock, occurs due to widespread vasodilation of the systemic vasculature. This vasodilation leads to a decrease in systemic vascular resistance, which results in the redistribution of blood flow away from vital organs and tissues, leading to inadequate tissue perfusion and shock.

D. "Distributive shock occurs due to increased systemic vascular resistance": This statement is incorrect. Distributive shock is characterized by decreased systemic vascular resistance due to vasodilation, not increased systemic vascular resistance. Increased systemic vascular resistance is more commonly associated with conditions such as hypertension or obstructive shock.

Correct Answer is ["B","C"]

Explanation

A. Increased number of individuals utilizing technology in their homes: While technology use may impact various aspects of cognitive function and mental health, there is insufficient evidence to suggest a direct correlation between technology use and the growing numbers of clients diagnosed with dementia.

B. Increased number of the population living longer: One of the primary risk factors for dementia is advancing age. As the population ages and life expectancy increases, there is a higher prevalence of dementia due to the age-related degenerative changes in the brain.

C. Increased number of Americans over the age of 65: Aging is the most significant risk factor for dementia. The aging population, particularly those over 65 years old, is experiencing a higher prevalence of dementia due to age-related changes in the brain.

D. Increased number of the population traveling abroad: There is no direct association between traveling abroad and the growing numbers of clients diagnosed with dementia in the United States. While certain environmental factors or exposures may influence dementia risk, travel patterns are not considered a significant contributing factor to the overall prevalence of dementia.

E. Increased number of Americans attending college: There is no evidence to suggest a direct link between attending college and the prevalence of dementia. Educational attainment may have a protective effect against dementia, but it is not a factor driving the growing numbers of diagnoses in the United States.

A. "Pentoxifylline can be administered to help the platelets from sticking together and occluding the vessels." B. "A heparin bolus is administered and followed with a continuous infusion to help keep the blood thinner." C. "A flexible catheter will be inserted into a vessel of the arm, neck, or groin and advanced to the heart to dilate a narrowed or occluded artery." D. "A small catheter with a balloon on the end is threaded into a vessel in the groin and advanced to the heart where the balloon will be inflated, and the narrowed valve will be dilated. "

Correct Answer is D

Explanation

A) "Pentoxifylline can be administered to help the platelets from sticking together and occluding the vessels": Pentoxifylline is a medication used to improve blood flow by decreasing the viscosity of blood. However, it is not typically used to treat mitral valve stenosis. This statement does not accurately reflect treatment options for this condition.

B) "A heparin bolus is administered and followed with a continuous infusion to help keep the blood thinner": Heparin is an anticoagulant used to prevent blood clot formation, but it is not a treatment for mitral valve stenosis itself. While anticoagulants may be used in certain situations with mitral valve stenosis (such as in the setting of atrial fibrillation), they do not directly address the underlying valve narrowing.

C) "A flexible catheter will be inserted into a vessel of the arm, neck, or groin and advanced to the heart to dilate a narrowed or occluded artery": This statement describes a procedure known as percutaneous transluminal mitral valvuloplasty (PTMV), which is a minimally invasive intervention used to treat mitral valve stenosis. During this procedure, a catheter with a deflated balloon on its tip is inserted into a vessel and guided to the heart, where the balloon is inflated to widen the narrowed valve.

D) "A small catheter with a balloon on the end is threaded into a vessel in the groin and advanced to the heart where the balloon will be inflated, and the narrowed valve will be dilated": This statement accurately describes balloon valvuloplasty, which is a common procedure used to treat mitral valve stenosis. By inflating the balloon within the narrowed valve, the procedure aims to widen the valve opening, thus improving blood flow through the heart.
