A patient is seen in the emergency department (ED) with heart failure. What key diagnostic test does the nurse assess to determine the severity of the patient’s heart failure?

Given two consecutive frames ‘0003FFE’ and ‘0004002’. How many “BYTES” are there in a single frame?

A client with a history of right-sided heart failure lives in a long-term care facility. In the daily assessment, the nurse is required to record the level of this client’s peripheral edema. Which would be the main area for examination?

Graduated compression stockings have been prescribed to treat a client’s venous insufficiency. What education should the nurse prioritize when introducing this intervention to the client?

Which of the following is a limitation of cross-sectional studies?

In a cross-sectional study, 1,000 individuals are randomly sampled. The sample proportion with diabetes is found to be 0.08. If the true population proportion is 0.10, what is the sampling error?

A prospective cohort study investigated the risk of developing diabetes over 10 years. Out of 2,500 participants, 500 were obese, and the rest were not. After 10 years, 100 obese participants developed diabetes, while 50 non-obese participants did. Calculate the relative risk (RR) of diabetes in obese individuals compared to non-obese individuals.

In the UK in 2015, the male population was approximately 31,000,000, of which 2,064,600 were obese. Calculate the prevalence of obesity in this population, expressed as a percentage.

In a case-control study examining smoking and lung cancer, 150 out of 200 cases are smokers, while 100 out of 400 controls are smokers. Calculate the odds ratio (OR) for smoking as a risk factor for lung cancer.

You are conducting a stratified sample of 1,000 participants from a population of 10,000 divided into two strata: 30% men and 70% women. How many men should be included in the final sample?
