When the nurse collects data at one point in time are called which of the following?
- 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.

A patient presents with chest pain that occurs during heavy lifting or physical exertion and is relieved by rest. An electrocardiogram (ECG) may show transient ST-segment depression. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Prinzmetal's angina
Correct Answer: A
Rationale: The given patient's symptoms of chest pain that occurs during heavy lifting or physical exertion and is relieved by rest are consistent with stable angina. Stable angina is characterized by predictable chest pain that occurs with exertion and is typically relieved by rest or nitroglycerin. The transient ST-segment depression on ECG is also a common finding in patients with stable angina, which reflects myocardial ischemia during episodes of chest pain triggered by exertion. In contrast, unstable angina is characterized by chest pain at rest or with minimal exertion that is of increasing frequency, severity, or duration. Acute myocardial infarction is associated with persistent ST-segment elevation or new Q-waves on ECG, and Prinzmetal's angina is characterized by chest pain at rest due to coronary artery spasm rather than exertion.
When Nurse Ace suubitted a report to the physician that she committed an error in medication. This is an example of
- A. Responsibility
- B. Commitment
- C. Accountability
- D. Delegation
Correct Answer: C
Rationale: Nurse Ace submitting a report to the physician about committing an error in medication demonstrates accountability. Accountability in healthcare refers to the responsibility of individuals to answer for their actions, decisions, and behaviors in the professional setting.

Compliance with reporting errors is essential for quality improvement and patient safety in healthcare settings.
Kris is a hospitalized movie star. A nursing assistant takes her picture without permission and sells it to a local newspaper. The nursing assistant could be quilts of:
- A. Invasion of privacy
- B. Defamation
- C. Abuse
- D. Assault and battery
Correct Answer: A
Rationale: This scenario falls under the category of invasion of privacy. Invasion of privacy occurs when a person's private information or images are shared or used without their consent, leading to an intrusion of their private life. In this case, Kris, as a hospitalized movie star, had her picture taken without permission by the nursing assistant, which was later sold to a local newspaper. Kris has a right to privacy, especially during a vulnerable time like being hospitalized, and the nursing assistant violated that right by taking and selling her picture without consent. This action constitutes an invasion of privacy.
A patient presents with progressive weakness, muscle atrophy, and fasciculations, primarily involving the upper and lower extremities. Over time, the patient develops difficulty swallowing and breathing. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Parkinson's disease
- B. Guillain-Barré syndrome (GBS)
- C. Amyotrophic lateral sclerosis (ALS)
- D. Myasthenia gravis
Correct Answer: C
Rationale: The symptoms described are classic for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to muscle weakness and atrophy. Patients typically present with weakness, muscle atrophy, fasciculations (muscle twitching), and eventually develop difficulty swallowing and breathing due to involvement of the muscles responsible for these functions. Parkinson's disease (Choice A) is a neurodegenerative disorder characterized by tremors, rigidity, and bradykinesia but does not typically present with muscle atrophy or fasciculations as described in the case. Guillain-Barré syndrome (GBS) (Choice B) is an acute inflammatory condition affecting peripheral nerves, leading to ascending paralysis, which is usually reversible. Myasthenia gravis (Choice D) is an autoimmune disorder that affects neu
