Rule of Nines for Burns NCLEX Quiz Questions (2024)

FAQs

What is the rule of 9 in Nclex? ›

The Rule of Nines assesses the proportion of body surface area with partial- and full-thickness burns. Partial-thickness burns affect the epidermis and the papillary or reticular dermis or both layers.

The rule-of-nines is a quick method to assess the extent of burn injury in an adult. To calculate the extent of the burn count: 9% for both the anterior and posterior surfaces of the head and neck. 9% for both the anterior and posterior surfaces of each upper limb (18% for both)

The rule of nines is a tool used to estimate a burn's percentage of your total skin. It divides your body into sections by multiples of 9% each.

The NCLEX is not based on a percentage of questions answered correctly. You can answer any number of questions between 75 and 265, and it could be a pass or fail. Your score is based on the computer's estimate of your ability to answer medium-difficult questions correctly at least 50% of the time.

When the NCLEX-RN shuts off at 85 questions, it means you either did very well or very poorly—enough so that the CAT model is 95% confident in your success or failure after only one-third of the possible 265 exam questions. Further, in an 85-question test only 70 questions are counted toward your passing score.

To estimate body surface area (BSA) of a burn, the rule of nines assigns BSA values to each major body part. The body parts that make up 9% each include the entire left arm, entire right arm, head, chest, and abdomen. You'll see that 3 parts are labeled 18% – the entire back, entire left leg, and entire right leg.

Using the Rule of Nines, calculate the total body surface area percentage that is burned? The answer is A. Anterior head and neck (4.5%), front and back of the left arm (9%), front of the right arm (4.5%), posterior trunk (18%), front and back of the right leg (18%), back of the left leg (9%) which equals 63%.

You can estimate the body surface area on an adult that has been burned by using multiples of 9. In an adult who has been burned, the percent of the body involved can be calculated as follows: If both legs (18% x 2 = 36%), the groin (1%) and the front chest and abdomen were burned, this would involve 55% of the body.

Extent of the Burn

Several methods are available to estimate the percentage of total body surface area burned. Rule of Nines - The head represents 9%, each arm is 9%, the anterior chest and abdomen are 18%, the posterior chest and back are 18%, each leg is 18%, and the perineum is 1%.

What is the rule of nines burn coding? ›

Code T31 to report a burn and T32 to report corrosion, based on the classic “rule of nines.” The rule of nines, for adult patients, assigns 1% of TBSA to the genitalia, and multiples of 9% to other body areas (9% head, 9% per arm, 18% per leg, etc.).

The "rule of palm" is another way to estimate the size of a burn. The palm of the person who is burned (not fingers or wrist area) is about 1% of the body. Use the person's palm to measure the body surface area burned.

What are the Pass/Fail Rules? The CAT algorithm determines whether you pass or fail based on one of the following three rules: the 95% Confidence Interval Rule, Maximum-Length Exam Rule, or the Run-out-of-time (ROOT) Rule.

The NCLEX scoring system uses a unit of measurement called logits to score questions and determine whether candidates pass or fail. Logits report the differences between the candidate's ability estimates and the question difficulty. The current passing standard of the NCLEX is -0.18 logits.

The minimum number of questions on the NCLEX-RN is 75.

This means that if you answer enough questions correctly to demonstrate competency, your exam can end after 75 questions. Conversely, the exam can continue up to 145 questions if more data is needed to assess your abilities accurately.

Current NCLEX Pass Rates

Currently, the first-time pass rate for NCLEX is 80%. However, this number will vary depending on where you go to school. So, regardless of how many questions you're asked, your odds of passing NCLEX are fairly high.
