Answer:

the correct answer is option A- Intercalated disc

Explanation:

Intercalated discs are the characteristic microscopic feature of the cardiac muscle which allows the cardiac cells to work as a single unit or syncytium.

The disc allows the cardiomyocytes (an individual cell) to act as one unit due to the "desmosomes and gap junctions" which allows the diffusion of ions to pass to nearby cardiomyocytes and allow depolarization of the entire heart which causes contraction.

Thus, option A- Intercalated disc is the correct answer.

After assessing the status of a newborn, the nurse is concerned that this newborn has persistent pulmonary hypertension. When ex

Katen [24]

When explaining the status of a newborn who has persistent pulmonary hypertension to the parents, the nurse would integrate knowledge about the foramen ovale which is still open.

Pulmonary hypertension happens when the blood pressure in the arteries that connect the heart and lungs is too high. Lung blood vessels develop more muscle on their inner walls as a result of pulmonary hypertension.

Blood arteries in the lungs are constricted, obstructed, or damaged in pulmonary arterial hypertension (PAH), one kind of pulmonary hypertension.

Due to the injury, blood pressure in the arteries of the lungs increases and blood flow through the lungs is slowed.

During foetal development, blood can travel through the foramen ovale, a muscle opening between the left and right atriums, and skip the pulmonary circulation.

Hence, The nurse would provide information regarding the still-open foramen ovale when describing the condition of a newborn with persistent pulmonary hypertension to the parents.

olchik [2.2K]

Implementation of the electronic health record offers many challenges accessibility would NOT be considered a critical challenge.

<h3>What is an electronic health record?</h3>

The computerized, digital form of health records in healthcare is called Electronic Health Records. It made patient health records easily accessible instead of paper health records.

Some of its advantages are-

Advanced quality of care, which includes error-free, easily accessible records;
Convenient – because it has eliminated burdensome paper works;
Saves space by stopping the use of heavy record files etc.

On the other hand, it has certain disadvantages of –

security issues, such as the advanced use of computer networks, made this information easy to hack or manipulate;
it needs immediate updating of records, failing which can lead to inaccuracy of data etc.

Thus, this could be the answer.

Pacemaker cells in the heart possess intrinsic rhythm. a. True b. False

Sveta_85 [38]

Answer:

True

Explanation:

Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.

Each class of pacemaker cells has its own intrinsic rate.

For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).

The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).
