Adult Health Nursing First Chapter Quizlet

Correct Answer: A

Rationale: Quality improvement measures are most effective when everyone within an organization is involved. This includes not only professional and management staff but also consumers or customers who are directly impacted by the products or services being provided. By involving everyone, a more comprehensive and diverse perspective can be gained, leading to better identification of areas for improvement and more successful implementation of quality improvement initiatives. Additionally, by involving all stakeholders, there is a greater buy-in and commitment to the process, increasing the likelihood of sustainable improvements being made.

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.

Correct Answer: B

Rationale: Cohort studies are types of epidemiological studies that involve a group of individuals who share a common characteristic or experience and are followed over time to observe the development of a particular health outcome. This type of study is useful in determining the incidence of a disease, identifying risk factors, and studying the natural history of a disease. Cohort studies allow researchers to investigate the relationship between exposure and outcome by following participants forward in time. It helps in establishing causality and is particularly useful for studying rare exposures or outcomes. In contrast, cross-sectional studies involve collecting data from a population at a single point in time, experimental studies involve interventions and control groups, and case-control studies involve comparing individuals with a particular health outcome (cases) to those without the outcome (controls) retrospectively.

Correct Answer: D

Rationale: Late decelerations on the fetal monitor tracing indicate a potential uteroplacental insufficiency, which could be caused by decreased oxygen supply to the fetus. One common cause of late decelerations is uterine hyperstimulation due to excessive use of oxytocin. By discontinuing the oxytocin infusion, the nurse can help alleviate the stress on the fetus and decrease the likelihood of further late decelerations. This action should be prioritized before other interventions such as changing the mother's position or administering oxygen. Immediate delivery may be necessary if the fetus continues to show signs of distress despite discontinuing the oxytocin infusion.

Correct Answer: D

Rationale: The presentation of a small, painless, well-defined nodule on the lateral aspect of the neck, above the clavicle, along with the cytology showing clusters of polygonal cells with abundant granular cytoplasm is most indicative of a parathyroid adenoma. Parathyroid adenomas are benign tumors derived from the parathyroid gland that can produce excess parathyroid hormone (PTH), leading to hyperparathyroidism. The characteristic histology of parathyroid adenomas includes chief cells with abundant granular cytoplasm.
