Lubov Fominskaja [6]
<h2>Question ❓Which symptoms are characteristic of a preschool-age client who is diagnosed with a urinary tract infection</h2>

<h2>Answer ❄️: </h2>

Pediatric Urinary Tract Infection

<h2>Explanation:⁉️</h2>

Practice Essentials

Urinary tract infection (UTI) is one of the most common pediatric infections. It distresses the child, concerns the parents, and may cause permanent kidney damage. Occurrences of a first-time symptomatic UTI are highest in boys and girls during the first year of life and markedly decrease after that.

Febrile infants younger than 2 months constitute an important subset of children who may present with fever without a localizing source. The workup of fever in these infants should always include evaluation for UTI. The chart below details a treatment approach for febrile infants younger than 3 months who have a temperature higher than 38°C.

Why do the different skeletal muscle fiber types vary in the speed and duration of their twitches?
IrinaVladis [17]

Answer:

The different skeletal muscle fiber types vary in the speed and duration of their twitches due to -

b) They vary in the rate of hydrolysis of ATP

c) They vary in the removal of Ca+ from the cytosol

Explanation:

There are mainly two types of muscle fibers , i.e.

a) slow twitching, long contraction duration( type I fibers)

b) First twitching but short duration of contraction. ( type II fibers).

Now think of the physiology of muscle. Two components are important, cytosolic Ca++ concentration and Availability of ATP. K+ is related to the action potential ( none or all law, there is no relation to the duration with respect to the potassium). For long contraction muscle fibers need a more steady supply of ATP, and also consistent high concentration of cytosolic Ca++ for muscle contraction to happen. So, these two factor is important for the duration of twitching. So the answer is option f .

A new client has been admitted with right-sided heart failure. When assessing this client, the nurse knows to look for which fin
jarptica [38.1K]

Fluid accumulation is the primary symptom of right-sided heart failure. Your feet, ankles, and legs will swell (edema) as a result of this buildup.

There is either low blood pressure or high blood pressure (130/80 mm Hg or above). Low blood pressure may indicate advanced heart failure. There is a third heart sound, which denotes irregular blood flow via the heart. There may or may not be heart murmurs. Consequently, the right chamber can no longer pump when you develop right-side heart failure. It follows that when your heart cannot pump enough blood, blood backs up into the veins. Your abdomen, ankles, and legs may likely enlarge if this occurs.
