15. The LPN is asked to perform an occult blood test. What type of sample should be collected? A.​ arterial blood sample B.​ sputum sample C.​ venous blood sample D.​ stool sample Correct Response: D Explanation : The correct answer is (D) stool sample. An occult blood test is designed to identify hidden (occult) blood in the stool, serving as an indicator of potential gastrointestinal bleeding. Collecting a stool sample is crucial for this test, as it allows healthcare professionals to assess the presence of blood in the digestive system. Arterial blood (A) is not typically used for occult blood testing, as it does not directly reflect gastrointestinal bleeding. Sputum (B) and venous blood (C) are also inappropriate choices for occult blood testing, as the focus of the test is specifically on detecting blood in the stool, not in respiratory or general circulatory systems. Therefore, the accurate and relevant specimen for an occult blood test is a stool sample, providing valuable insights into the presence of gastrointestinal bleeding. (See Fecal Occult Blood Testing (Guaiac Screening) ) 16. Your client is experiencing general malaise. Which stage of infection is this client in? A.​ The incubation stage B.​ The illness stage C.​ The prodromal stage D.​ The convalescence stage Correct Response: C Explanation : The correct answer is (C) the prodromal stage. General malaise in a client indicates the prodromal stage of infection, characterized by non-specific symptoms such as fatigue, muscle and joint pain, reduced appetite, and the onset of headaches. This stage follows the incubation stage (A) , which is the initial phase of an infection that begins upon pathogen entry into the host and ends when signs and symptoms become evident. The illness stage (B) comes next, marked by the continuation of symptoms, although generally less severe than during the prodromal stage. Finally, the convalescence stage (D) represents the recovery period, during which symptoms gradually disappear. Understanding these stages is crucial for healthcare professionals in providing appropriate care and interventions based on the progression of the infection. (See Stages of Infection ) 17. The LPN is helping a client get out of bed to use the restroom. Which of these actions represents proper ergonomic practice? A.​ Bend over the clients to get a good grip when sitting the client up. B.​ Lift the client into a standing position by using your leg and back muscles. C.​ Aid the client in sitting/standing by lifting with the legs and keeping the back straight.
