Based on the Holliday-Segar method, a school-age child weighing 35 kg would have a daily maintenance fluid requirement of 1800 mL per day.

In general, calculating a child's daily maintenance fluid requirement involves using a formula that takes into account the child's weight. One commonly used formula is the Holliday-Segar method. According to this method, the daily maintenance fluid requirement for a child is calculated as follows:

First 10 kg: 100 mL/kg/day

Next 10 kg: 50 mL/kg/day

Remaining kg: 20 mL/kg/day

In this case, the child weighs 35 kg. Using the Holliday-Segar method, we can calculate the child's daily maintenance fluid requirement as follows:

For the first 10 kg: 10 kg x 100 mL/kg/day = 1000 mL/day

For the next 10 kg: 10 kg x 50 mL/kg/day = 500 mL/day

For the remaining 15 kg: 15 kg x 20 mL/kg/day = 300 mL/day

Adding these values together, the child's daily maintenance fluid requirement would be:

1000 mL/day + 500 mL/day + 300 mL/day = 1800 mL/day

Therefore, the child's daily maintenance fluid requirement would be 1800 mL per day. It's important to note that this is a general calculation, and individual variations and specific clinical conditions should be taken into consideration when determining the actual fluid requirements for a child.

Answer:

Option D. Mutation.

Explanation:

Bacterial resistance to medications often occurs when the bacteria is exposed to medication that is meant to eliminate it but is unsuccessful for a myriad of potential reasons. In doing so, the bacteria are able to adapt under the pressure of elimination, mutate their DNA to develop resistant traits and then proliferate with this new DNA.

So, you cannot have option A as a factor of antimicrobial resistance without option D. Attenuation would be a premature termination of DNA transcription which is used not in antimicrobial medications but in vaccines! Specialization is the normal evolution and assignment specific functions for cells.  

A nurse recalls bacteria become resistant to antimicrobials by Mutation. The correct answer is option D.

Antimicrobial resistance occurs when bacteria evolve mechanisms to defend themselves against antimicrobial drugs, rendering the drugs ineffective. This evolution is often driven by genetic mutations that occur naturally in bacterial populations, leading to the development of resistance traits.

When exposed to antimicrobials, bacteria that possess these traits are better able to survive and proliferate, leading to the emergence of drug-resistant strains. It is important to note that the overuse and misuse of antimicrobials also contributes to the development of antimicrobial resistance by providing selective pressure for the growth and spread of resistant bacteria.

As a nurse, it is important to provide parents of a 4-month-old infant with instructions on injury prevention during a well-baby checkup.

While all of the answer choices listed may be relevant at some point, the most appropriate instruction to include at this time is to supervise the infant to prevent falls off of surfaces he is laying on now that he is rolling. This is because at this age, infants are typically developing their gross motor skills and may begin to roll over. It is important to ensure that the infant is always placed on a safe and secure surface, such as a firm and flat crib mattress, and to supervise them to prevent any falls.

Finally, it is important to remind parents to never shake baby powder near the infant's face because it can be aspirated and cause respiratory problems. Overall, providing instructions on injury prevention is a critical component of ensuring the safety and well-being of infants.
