  • A. Time series.
  • B. Longitudinal
  • C. Cross-sectiona l
  • D. Crossover
Correct Answer: C

Rationale: When the nurse collects data at one point in time, it is referred to as a cross-sectional study. Cross-sectional studies are observational research designs that provide a snapshot of a population or a sample at a specific point in time. This type of study can help identify associations or relationships between variables at a single time point but cannot establish causality or determine changes over time. In contrast, time series involve collecting data over multiple time points, longitudinal studies follow individuals or samples over time to track changes or outcomes, and crossover studies involve multiple interventions or treatments over different periods.
