A postoperative client who underwent surgery 12 hours ago is found having difficulty breathing. He has petechiae over his chest, dyspnea and complains of acute chest pain. What action should the nurse take first?

An older adult client with heart failure is being discharged home on an ACE inhibitor and a loop diuretic. The client’s most recent vital signs prior to discharge include oxygen saturation of 93% on room air, heart rate of 81 beats per minute, and blood pressure of 89/59 mm Hg. When planning this client’s subsequent care, what nursing diagnosis should be identified for this client regarding the current presentation?

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?

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.
