A nurse is teaching an ACLS class and is discussing heart rhythms and treatment. Which of the following rhythms would indicate the need for defibrillation?

Choice A reason: A client who works in a child care center is not typically at risk for hepatitis C unless they are exposed to blood or bodily fluids from an infected individual. Hepatitis C is primarily spread through blood-to-blood contact. While working in a child care center may increase the risk of exposure to various infections due to close contact with children, it is not a common route of transmission for hepatitis C.

Choice B reason: Eating raw shellfish is more commonly associated with hepatitis A and E, which are transmitted through the fecal-oral route, often due to contaminated food or water. Hepatitis C, however, is not typically transmitted through food or water. It is a bloodborne virus, and thus, eating raw shellfish would not be considered a high-risk activity for contracting hepatitis C.

Choice C reason: A client who has multiple tattoos is at risk for developing hepatitis C, particularly if the tattoos were done using non-sterile equipment or in an unregulated setting. The hepatitis C virus can be transmitted through the use of contaminated needles, which can occur in tattoo parlors that do not adhere to strict hygiene and sterilization practices. This is why choice C is the correct answer. While all the options presented could potentially involve some risk of infection, it is the client with multiple tattoos who is most at risk for hepatitis C, assuming the tattoos were obtained in a setting where infection control practices were not followed. It’s important for healthcare providers to assess each client’s individual risk factors and educate them on the ways to prevent hepatitis C, such as ensuring the use of sterile needles for tattoos and piercings.

Choice D reason: Traveling to an underdeveloped country may increase the risk of various infectious diseases, but hepatitis C is not commonly spread through casual contact or environmental factors. It requires blood-to-blood contact for transmission. Therefore, unless the client engaged in activities that involved such exposure, like receiving medical or dental procedures with non-sterile equipment, simply traveling to an underdeveloped country does not significantly increase the risk of contracting hepatitis C.

Choice A reason: Bradycardia, which is a slower than normal heart rate, is not a common finding associated with renal calculi. Renal calculi, or kidney stones, typically cause symptoms related to the urinary system rather than directly affecting the heart rate.

Choice B reason: Bradypnea, or abnormally slow breathing, is also not a typical symptom of renal calculi. Patients with kidney stones may experience changes in urination patterns, such as frequency or urgency, but not typically changes in respiratory rate.

Choice C reason: Severe pain is indeed the most common symptom associated with renal calculi. This pain, known as renal colic, is often sudden in onset, very severe, and may radiate from the back down to the lower abdomen or groin. The pain is caused by the stone moving into the ureter and causing a blockage, which leads to increased pressure and stretching of the kidney or ureter. Renal calculi can cause a range of symptoms, with severe pain being the most prominent and often the first symptom that leads individuals to seek medical care. The pain is typically very intense and can be accompanied by other symptoms such as nausea, vomiting, and hematuria (blood in the urine).

Choice D reason: Nocturia, or frequent urination at night, can be a symptom of renal calculi, especially if the stones affect the bladder or cause urinary tract infections. However, the most characteristic symptom of renal calculi is severe pain, not necessarily nocturia.
