Glut injection site

Arturiano [62]

To find the correct location for injecting into the Gluteus maximus muscle, expose the buttocks and divide (in your mind) each buttock into four parts. Aim the injection into the upper quarter of the buttock (X on the diagram), towards the hip bone portion but below the iliac crest which is the bony part of the hip.

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a G of -20 kcal/mol. If you double the amount

luda_lava [24]

Answer:

-20 kcal/mol (It stays the same)

Explanation:

Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.

Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.

Free energy of reaction

= free energy of product - free energy of substrate

The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.

The attached image shows the effect of changes in enzyme concentration on the free energy.

A baby is assessed at one minute after birth using the Apgar scale. Three of the five vital signs are good, but the baby is weak

timama [110]

Answer: The two vital signs the medical team is concerned about are:

1. MUSCLE TONE

2. REFLEX IRRITABILITY

Explanation:

What does APGAR stand for, and what does it measure?

When the scoring system was put into common use, medical professionals created an acronym using Apgar’s last name, so that each criterion included in the assessment would be easier to remember. The five criteria assessed in the Apgar score are:

A – Appearance (skin color)

This is an evaluation of the baby’s skin color. The medical team measures if the baby blue or pale all over, blue at the extremities, or pink all over.

P – Pulse (heart rate)

During this evaluation, the medical team measures if the baby’s heart rate is absent, slow (<100 beats per minute (bpm), or fast (>100 bpm).

G – Grimace (reflex irritability/response)

During this evaluation, the medical team asks if the baby lacks a response to stimulation, responds with a grimace, or responds by crying and pulling away.

A – Activity (muscle tone)

During this evaluation, the medical team asks if the baby is limp, if the baby has some flexion (joint movement), or if the baby shows active motion.

R – Respiration (breathing ability)

During this step, the medical team asks if the baby is failing to breathe, if the baby has a weak cry and slow breathing, or if the baby is breathing well and crying normally.
