Effective learning by a student nurse regarding cardiac output can be assessed through their understanding of the concept and its related statements

QUESTION

Question 20 (2 points) A registered nurse is teaching nursing students about cardiac output. Which statement indicates effective learning by the student nurse? Question 20 options: “Cardiac output is the amount of blood that the heart pumps out of the left ventricle.” “Cardiac output is increased in heart failure.” “Cardiac output is unvaried by body size.” “Adrenergic stimulation slows heart rate and cholinergic stimulation raises heart rate.” Question 21 (2 points) The radiographic reports of a client reveal inflammation of the metatarsophalangeal joint of the great toe. Which disorder should the nurse suspect in the client? Question 21 options: Gout Lyme disease Septic arthritis Polymyalgia rheumatica Question 22 (2 points) Which pathophysiological condition particularly activates the trigeminovascular system? Question 22 options: Epilepsy Cluster headache Parkinson’s disease Tension headache

ANSWER

Question 20: Effective Learning About Cardiac Output

Effective learning by a student nurse regarding cardiac output can be assessed through their understanding of the concept and its related statements. Among the options provided:

“Cardiac output is the amount of blood that the heart pumps out of the left ventricle.”

This statement accurately defines cardiac output as the volume of blood ejected by the heart, specifically the left ventricle, in a minute. It demonstrates effective learning as it correctly defines the concept.

“Cardiac output is increased in heart failure.”

This statement is inaccurate. Cardiac output is typically reduced in heart failure, not increased. Therefore, this statement does not reflect effective learning.

“Cardiac output is unvaried by body size.”

This statement is also incorrect. Cardiac output can vary with body size and individual factors. Effective learning should involve understanding that cardiac output can change based on various physiological and pathological conditions.

“Adrenergic stimulation slows heart rate and cholinergic stimulation raises heart rate.”

This statement contains inaccuracies. Adrenergic stimulation typically increases heart rate, while cholinergic stimulation tends to decrease it. Therefore, this statement does not demonstrate effective learning.

Question 21: Suspecting a Disorder Based on Radiographic Reports

When interpreting radiographic reports indicating inflammation of the metatarsophalangeal joint of the great toe, the nurse should consider various possibilities. In this case, the disorder that the nurse should suspect is:

Gout

Gout is a condition characterized by the deposition of urate crystals in joints, often affecting the metatarsophalangeal joint of the great toe. Inflammation and severe pain in this joint are common manifestations of gout.

Question 22: Activation of the Trigeminovascular System

The trigeminovascular system is primarily associated with certain types of headaches. Among the options provided:

Cluster headache

Cluster headaches particularly activate the trigeminovascular system. These headaches are characterized by severe, excruciating pain, often around one eye, and are known to involve the trigeminal nerve and its vascular components.

Cluster headaches can be excruciating and are typically recurring, making them a prime example of a condition that activates the trigeminovascular system.

In summary, effective learning by the student nurse regarding cardiac output involves understanding its definition and how it can vary based on physiological conditions. Suspecting gout based on inflammation of the metatarsophalangeal joint is a relevant assessment. Lastly, cluster headaches are known to particularly activate the trigeminovascular system.
