When one set of erythrocytes is placed in a beaker containing 0.9% NaCl, nothing happens to the cells because 0.9% NaCl is isotonic to the cells.
In biology, a solution outside the cell is called hypotonic if it has a lower solute concentration relative to the cytosol. Due to osmotic pressure, air diffuses into the cell, and the cell often appears turgid, or bloated.
Animal cells are put into a hypertonic solution then the animal cells will experience creation. Crenation is a condition in which cells shrink or break down. Meanwhile, if an animal cell is placed in a hypotonic solution, the cell will experience lysis, namely the condition of the cell breaking.
Isotonic has the same concentration of NaCl solution and blood cells, so nothing happens.
So, the correct answer is D.

What actions should a nurse implement when a client refuses a treatment ?
The nurse should first assess the client's comprehension of the treatment and the rationale for its suggestion. If the client is not fully informed, the nurse should educate them and clear up any misconceptions. If the client is aware of the treatment but still rejects, the nurse should respect the client's autonomy and right to make healthcare decisions for themselves.
However, if refusing the therapy could endanger the client or others, the nurse may need to take additional precautions to guarantee their safety. In circumstances when treatment is required to avoid the spread of a contagious disease, for example, the nurse may need to confer with the client's healthcare professional or seek legal advice.

The non-invasive ABR (Auditory Brainstem Response) test is given to an infant when it is suspected that he or she might have a hearing loss.
This test measures the electrical activity generated by the auditory nerve and brainstem in response to sound stimuli.
ABR is a painless and non-invasive test that can be performed on infants who are too young or uncooperative for conventional behavioral hearing tests. The infant is typically sleeping or relaxed during the test, and electrodes are placed on their scalp to measure the electrical response.
ABR is used to diagnose hearing loss in infants, including congenital or early-onset hearing loss, as well as to monitor the progression of hearing loss in infants with conditions such as premature birth, meningitis, or genetic disorders.
The ABR test provides important information to guide clinical decision making and ensure that infants with hearing loss receive appropriate intervention and support to enhance their language and cognitive development.
