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

A nurse is admitting a client who has suspected retinal detachment.
Which of the following questions should the nurse include when gathering a client history? (Select All that Apply.)
A. "Have you had any trauma to the eye?"
"Have you had any trauma to the eye?": Trauma to the eye can be a significant risk factor for retinal detachment. Inquiring about any history of eye trauma is essential to understand potential causes or contributing factors.
B. "Do you regularly lift heavy objects?"
"Do you regularly lift heavy objects?" - Regularly lifting heavy objects can increase pressure in the eyes, which can contribute to retinal detachment.:
C. "How much sodium is in your diet?"
"How much sodium is in your diet?": Sodium intake is not directly linked to the risk of retinal detachment. While diet and nutrition play a role in overall eye health, sodium consumption is not a specific risk factor for retinal detachment.
D. "Do you wear sunglasses when in direct sunlight?"
"Do you wear sunglasses when in direct sunlight?": Prolonged exposure to sunlight without eye protection can increase the risk of retinal detachment. Wearing sunglasses with UV protection can help prevent eye damage, including retinal detachment.
E. "Do you take steroids?"
"Do you take steroids?": Steroid use, especially long-term or systemic steroids, can increase the risk of developing retinal detachment. Steroids may lead to changes in the structure and integrity of ocular tissues, predisposing individuals to retinal detachment.

A nurse is obtaining a preoperative medical and surgical history from a client scheduled for a cataract extraction procedure. Which of the following client statements require further investigation by the nurse?
A. "l stopped taking aspirin last week."
"I stopped taking aspirin last week.": Stopping aspirin medication prior to surgery is often advised to reduce the risk of bleeding during and after the procedure. The nurse may confirm the timing of discontinuation with the client and verify if any other anticoagulant medications are being taken.
B. "l did not put my contact lenses in this morning."
"I did not put my contact lenses in this morning.": Removing contact lenses before surgery is a routine precaution to prevent potential corneal abrasions or complications during the procedure. This statement indicates the client is following preoperative instructions.
C. "l took my blood pressure meds with a sip of water."
"I took my blood pressure meds with a sip of water.": Taking blood pressure medications with a small amount of water is generally acceptable before surgery. However, the nurse may verify the specific medications the client is taking and their dosing schedule to ensure compliance.
D. "l had a cough and runny nose a couple days ago."
"I had a cough and runny nose a couple days ago.": This statement requires further investigation as respiratory symptoms, such as cough and runny nose, may indicate an underlying respiratory infection. Infections can increase the risk of complications during surgery, such as anesthesia-related respiratory issues or postoperative infections. The nurse should assess the severity and duration of the symptoms, inquire about any fever or recent exposure to illnesses, and consider notifying the surgical team for further evaluation and decision-making regarding the client's surgical readiness.

A nurse is caring for a group of clients with dementia. The nurse recognizes which of the following factors as reasons for the growing numbers of clients diagnosed with dementia in the United States?
(Select All that Apply.)
A. Increased number of individuals utilizing technology in their homes
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
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
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
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
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.
