A nurse is preparing a client for a scheduled adenosine stress test. Which statement made by the client indicates a need for further education?

The answer is Option C ("My family is bringing me a cup of coffee to drink before the test.")

Explanation:

Adenosine stress test :

Adenosine stress test also referred to as myocardial perfusion imaging is a non-invasive imaging test which uses radioactive material called tracers to show areas of the heart muscle that aren’t getting enough blood flow. Pharmaceutical stress is used to increase blood flow to the heart muscle. The administration of adenosine acts on the cardiovascular system and to promote vasodilatation.

Some of the side effects of Adenosine are: flushing , dizziness, head pressure, nausea , chest pain.

There is a need to abstein from caffeine and other methylxanthines before the adenosine stress test for at least 24 hours before testing.  caffeine intake may interfere with adenosine-induced coronary hyperemia and myocardial perfusion imaging. Coffee drink contains caffeine which raises blood pressure and heart rate. It also increases the risk of developing irregular heartbeat.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
