Answer:
The correct answer is option C. ear.
Explanation:
A myringotomy is a surgery in which a very small incision is made in the tympanic membrane or eardrum of the ear by the surgeon to release pressure created by excessive fluid, or to remove pus from the middle ear.
The surgeon uses the myringotomy knife to create an incision in the tympanic membrane. The myringotomy knife is a needle-like a lancet blade which helps in piercing and incision.
Thus, the correct answer is option C. ear.
Answer:
I believe the answer is <u>retroviruses</u>
Explanation:
Reverse transcriptase is an enzyme found in retroviruses that converts the RNA genome carried in the retrovirus particle into double-stranded DNA. Reverse transcriptase first transcribes a complementary strand of DNA to make an RNA:DNA hybrid.
Answer:
The charge particle will have 0 mV and stationary
Explanation:
using V= W/q = kQ/r = 3.07 mV from both sides , makes it zero. since the charges on proton = electron but opposite charges (1.6*10^-16).
Nurses should receive training and practice in employing ultrasonic (US) guidance in order to reduce the threshold for using it during peripheral intravenous cannulation.
<h3>Abstract:</h3>
Aim:
The main goal of the study was to estimate how many procedures beginners must complete before becoming proficient at US-guided peripheral intravenous cannulation.
Materials and procedures:
After a theoretical training session, a multicenter prospective observational study was divided into two phases: supervised life-case training and practical training. The goal was to determine how many US-guided peripheral intravenous cannulations a participant would need to complete before being considered competent in the life-case scenario. Each participant's specific learning curve was determined via cusum analysis.
Results:
A total of 1855 procedures were carried out by the 49 participating practitioners. During the initial procedure, first, try cannulation success was 73 percent; however, it climbed to 98 percent on the forty-first attempt (p 0.001). This study's overall first-try success rate was 93 percent. According to the cusum learning curve for each practitioner, proficiency was attained after a median of 34 procedures. The amount of time needed to complete a procedure successfully dropped as the practitioner's experience increased, from 14 minutes for the first procedure to 3 minutes for the forty-first (p 0.001).
Conclusions:
By adhering to a set educational programme, one can become proficient in US-guided peripheral intravenous cannulation, which increases the success rate of cannulation attempts on the first try as more procedures are conducted.
