When there's no water and you start to dehydrate, your salivary glands start working extra hard because your mouth can't be dry and the salivary glands produce saliva to keep the mouth and the throat dry. If your throat and mouth are dry you can't even swallow.</span>

The allele for brown fur in mice (B) is dominant over the allele for white fur (b).
evablogger [386]

Answer:

Genotype: Bb (heterozygous)

Phenotype: brown fur

Explanation:

Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.

As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.

Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.

The nurse provides a list of instructions to a client being discharged to home with a peripherally inserted central catheter (PICC). The nurse determines that the client needs further instructions if the client made which statement?

1. "I need to wear a MedicAlert tag or bracelet."

2. "I need to restrict my activity while this catheter is in place."

3. "I need to keep the insertion site protected when in the shower or bath."

4. "I need to check the markings on the catheter each time the dressing is changed."

Answer:

The correct answer is statement 2.

Explanation:

A flexible and thin tube, which is administered into the upper arms' vein and guided towards the superior vena cava is known as PICC or peripherally inserted central catheter. It has an application at the time of blood transfusions, providing intravenous fluids, at the time of chemotherapy, and for other activities.  

In the given case, it is the job of the nurse to teach the client that only minor activity limitations is needed when PICC is administered. However, one should ensure the protection of the site at the time of taking bath, should use a MedicAlert device and should look for the markings on the catheter at the time of changing dressing in order to evaluate dislodgement of the catheter.
