Question 1 of 5
The nurse is caring for a patient who is scheduled for a magnetic resonance imaging (MRI) scan. What explanation should be provided to the patient and family?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of these locations in the forebrain is the master control center for homeostasis through the autonomic and endocrine systems?
Correct Answer: A
Rationale: The correct answer is A: hypothalamus. The hypothalamus is the master control center for homeostasis as it regulates various bodily functions through the autonomic and endocrine systems. It plays a crucial role in maintaining body temperature, hunger, thirst, sleep, and hormone regulation. The thalamus (B) is responsible for sensory relay, the amygdala (C) is involved in emotion processing, and the cerebral cortex (D) is responsible for higher cognitive functions. Therefore, the hypothalamus is the correct choice for controlling homeostasis in the body.
Question 3 of 5
The central nervous system is made up of
Correct Answer: D
Rationale: The correct answer is D: the brain and spinal column. The central nervous system comprises the brain and spinal cord, which are responsible for processing and transmitting information throughout the body. The brain controls cognitive functions and coordinates movement, while the spinal cord serves as a pathway for nerve signals. Explanation: 1. The brain is the primary organ for processing information and controlling bodily functions. 2. The spinal cord acts as a conduit for nerve signals to travel between the brain and the rest of the body. 3. Together, the brain and spinal cord form the central nervous system, playing a crucial role in overall body function. Summary of other choices: A: Sensory organs and muscles do not constitute the central nervous system. Sensory organs detect stimuli, while muscles are part of the peripheral nervous system. B: The brain and muscles are not the only components of the central nervous system. The spinal cord is also a crucial part. C: While the sensory organs and spinal cord are components of the nervous system
Question 4 of 5
What is the biological vector for African sleeping sickness?
Correct Answer: B
Rationale: The correct answer is B: tsetse fly. Tsetse flies are the biological vectors for African sleeping sickness, caused by the parasite Trypanosoma brucei. Tsetse flies transmit the parasite through their bite, leading to the infection in humans. Mosquitoes (choice A), deer ticks (choice C), and sand flies (choice D) are vectors for other diseases such as malaria, Lyme disease, and leishmaniasis, respectively. Therefore, they are not associated with the transmission of African sleeping sickness.
Question 5 of 5
An elderly patient is brought to the clinic for confusion, horizontal eye movement bilaterally, and intermittent disorientation to time and place over the past 3 months. The patient has a history of alcoholism for 30 years. Which dementia type is the patient most likely experiencing?
Correct Answer: A
Rationale: The correct answer is A: Wernicke's encephalopathy. This patient's history of chronic alcoholism puts them at risk for thiamine deficiency, leading to Wernicke's encephalopathy. Symptoms such as confusion, horizontal eye movement abnormalities (nystagmus), and disorientation are classic features. Pick's disease (B) is a rare form of frontotemporal dementia with distinct pathological features. Lewy bodies (C) are associated with dementia with Lewy bodies, characterized by visual hallucinations and parkinsonism. Parkinson's disease (D) primarily presents with motor symptoms like tremors and rigidity, not cognitive deficits like this patient.
