Which AI algorithm builds a model by splitting the dataset recursively based on feature values?
K-Means Clustering
Neural Network
Support Vector Machine
Decision Tree
Decision trees recursively split data based on features to create a tree-like model for classification or regression. K-Means is a clustering method, SVM uses hyperplanes, and neural networks use layered perceptrons. The recursive splitting is unique to decision trees.
What does HIPAA regulate in healthcare AI?
Clinical decision-making algorithms
Medical device manufacturing
Telemedicine reimbursement
Data privacy and security
HIPAA sets standards to protect patient medical information and ensure data privacy and security. It does not specifically regulate algorithm design, payment policies, or manufacturing processes. Its focus is on safeguarding personal health data.
Telemedicine refers to:
Pharmaceutical manufacturing
Automated lab testing
Remote delivery of healthcare services using telecommunications
In-person hospital visits
Telemedicine uses telecommunications technology to provide clinical healthcare services remotely, such as consultations and monitoring. It is distinct from in-person visits, lab automation, or drug manufacturing. It enhances access to care over distances.
Which machine learning model is most suited for image recognition tasks in diagnostics?
K-Nearest Neighbors
Convolutional Neural Network
Logistic Regression
Linear Regression
Convolutional Neural Networks use convolutional layers to capture spatial patterns in images, making them ideal for diagnostic imaging like X-rays and MRIs. Other models lack built-in mechanisms for hierarchical feature extraction. CNNs outperform simpler models on image tasks.
A primary ethical concern with AI-driven healthcare systems is:
Reducing computation time
Ensuring equitable treatment across patient groups
Maximizing profit margins
Standardizing programming languages
Fairness and bias mitigation are critical to prevent AI systems from delivering unequal care to different patient populations. Computational efficiency and profit goals are operational considerations but not core ethical issues. Programming language choice is technical, not ethical.
An advantage of Random Forest over a single Decision Tree is:
Improved generalization by averaging multiple trees
Easier interpretability
Lower computation cost
Requires no hyperparameter tuning
Random Forest aggregates the predictions of many trees to reduce overfitting and improve generalization. It is more computationally intensive, less interpretable, and still requires tuning of parameters like tree count and depth.
Differential privacy in healthcare AI aims to:
Use fingerprint biometrics for access control
Remove all identifiers from a dataset manually
Encrypt data at rest only
Add statistical noise to data queries to protect individual patient data
Differential privacy injects controlled noise into query outputs so individual records remain unidentifiable while preserving overall data utility. Manual de-identification, encryption, and biometrics address privacy differently and are not the core principle of differential privacy.
Reinforcement learning can support clinical decision-making by:
Translating medical text
Diagnosing diseases using static rule-based systems
Directly storing patient records
Learning optimal treatment policies through trial-and-error interactions with simulated environments
Reinforcement learning seeks to maximize rewards by exploring and exploiting policies in simulated scenarios, such as treatment planning. It does not handle record storage, static rule-based diagnosis, or language translation, which are separate tasks.
In SVM, the kernel function is used to:
Cluster data points into groups
Initialize neural network weights
Transform input data into higher-dimensional space for separation
Reduce the number of features via dimensionality reduction
SVM kernels map data into a space where a linear boundary can separate classes that are not linearly separable in the original space. Dimensionality reduction, weight initialization, and clustering are distinct techniques.
Which encryption method provides end-to-end security for transmitting patient data over networks?
Base64 encoding
Transport Layer Security (TLS)
ZIP compression
Hashing with MD5
TLS encrypts data between client and server, ensuring confidentiality in transit. Base64 encodes but does not secure, MD5 hashing provides integrity checks not confidentiality, and ZIP compresses data without encryption unless additional layers are applied.
Natural Language Processing (NLP) in healthcare can be used to:
Enhance MRI resolution
Extract clinical concepts from unstructured notes
Perform blood analysis
Manufacture medical devices
NLP processes free-text medical records to identify diagnoses, medications, and other clinical entities. Device manufacturing, lab tests, and image resolution improvement are outside the typical scope of NLP.
Integrating AI chatbots into patient triage can:
Manufacture pharmaceuticals
Replace imaging radiologists entirely
Guarantee diagnosis accuracy without clinician oversight
Provide initial symptom assessment and direct patients to appropriate care levels
AI chatbots can collect patient symptoms, suggest next steps, and streamline triage, but they do not supplant radiologists, produce medications, or eliminate the need for clinical judgment.
Data pseudonymization differs from anonymization in that pseudonymization:
Completely deletes all personal data irreversibly
Groups patients by age only
Replaces identifiers with reversible tokens while retaining the ability to re-identify under control
Encrypts data only at rest
Pseudonymization substitutes identifiable data with coded tokens that can be reversed under appropriate controls, preserving linkage possibilities. Anonymization irreversibly removes identifiers, and encryption or age grouping are separate processes.
Which practice helps mitigate overfitting in a diagnostic ML model?
Cross-validation to evaluate performance on unseen data
Training solely on test data
Setting training epochs to a very high number without validation
Using all available features without selection
Cross-validation partitions data to ensure the model is tested on unseen subsets, indicating whether overfitting occurs. Using all features indiscriminately, training on test data, or excessive unvalidated epochs worsen overfitting.
In telemedicine, wearable sensors primarily enable:
Generating medical prescriptions autonomously
Continuous monitoring of vital signs and remote patient data collection
Operating surgical robots
Automated billing for services
Wearable sensors collect physiological data like heart rate and transmit it for remote monitoring and analysis in telemedicine. Billing, prescription generation, and robotics involve different technologies.
How do Generative Adversarial Networks (GANs) assist in medical imaging for rare diseases?
Classify images using predefined rules
Reduce image file size without quality loss
Generate synthetic images to augment training datasets and improve model robustness
Encrypt patient images for secure storage
GANs train a generator and discriminator adversarially to produce realistic synthetic images, expanding limited datasets for rare conditions and enhancing robustness. They are not encryption, rule-based classifiers, or compression tools.
The trade-off between algorithmic transparency and patient privacy arises because:
Detailed model explanations may expose sensitive training data and patient information
Privacy regulations require open-source code
Transparent algorithms are always slower to run
Patient privacy is unaffected by model interpretability
Providing in-depth explanations of model behavior can inadvertently reveal training data characteristics that include private patient information. Algorithm speed, unaffected privacy, and open-source mandates are not at the core of this ethical trade-off.
Federated learning in healthcare improves data security by:
Encrypting data with symmetric keys before analysis
Training models locally on hospital data and sending only model updates instead of raw patient data
Requiring clinicians to manually review every data point
Centralizing all patient records in a single database
Federated learning enables decentralized model training, keeping sensitive patient records in local systems and sharing only encrypted gradients or updates. Centralizing data, manual review, and encryption are different approaches.
To prevent catastrophic forgetting in continuous learning healthcare AI systems, one approach is:
Using only single-layer perceptrons
Resetting model weights randomly after each training cycle
Training exclusively on the most recent data only
Implementing elastic weight consolidation to protect important parameters from drastic updates
Elastic weight consolidation adds a penalty to changes in weights deemed important for previous tasks, preserving earlier knowledge while learning new information. Random resets, focusing solely on new data, or simplistic architectures fail to address forgetting.
What is a key challenge when deploying AI inference in low-resource telehealth settings?
Excessive availability of high-end GPUs
Limited computational power and intermittent network connectivity impacting real-time analysis
Lack of any patient data for model training
Overabundance of medical specialists on-site
Resource-constrained telehealth environments often have limited processing capacity and unstable network access, which can disrupt real-time AI analytics. The other options do not reflect common deployment constraints.
