Left Atria

Right Atria

Right Ventricle

Answer and Explanation

The Correct Answer is A

The left ventricle is responsible for pumping oxygen-rich blood from the heart to the rest of the body. In heart failure, the left ventricle is weakened and unable to pump blood efficiently, resulting in reduced blood ﬂow to the body's tissues. This can lead to symptoms such as fatigue, shortness of breath, and swelling in the legs and feet. Treatment for heart failure may include medications, lifestyle changes, and in some cases, surgical interventions such as a heart transplant.

Correct Answer is D

Explanation

Explanation: The normal range of sodium (Na+) in the blood is 135-145 mEq/L. The patient's sodium level of 121 mEq/L is below the normal range, indicating a low sodium level, which is called hyponatremia.

Hyponatremia is a common electrolyte imbalance that can be caused by a variety of factors, including excessive sweating, vomiting, diarrhea, certain medications, kidney disease, and hormonal imbalances. It can cause symptoms such as nausea, headache, confusion, seizures, and coma, and it can be a medical emergency if the sodium level drops rapidly or severely.

A. The chest tube drainage system should be placed on the bedside table. B. The chest tube drainage system should be placed on the bed near the patient. C. The chest tube drainage system must be placed below the site of insertion. D. The chest tube drainage system should be placed on the siderail near the patient.

Correct Answer is C

Explanation

: Chest tube placement is done to remove air or ﬂuid from the pleural space, which is the area between the lungs and the chest wall. The chest tube drainage system is an important tool to monitor and manage the drainage from the chest tube.

It is essential that the chest tube drainage system is placed below the level of the patient's chest and the site of insertion. This is necessary to create a continuous drainage system by allowing gravity to assist in the ﬂow of air or ﬂuid out of the pleural space. If the chest tube drainage system is placed above the insertion site, the ﬂuid will not drain properly, which can cause the ﬂuid to back up into the patient's chest cavity, leading to complications such as pneumothorax or hemothorax.

Therefore, the appropriate statement regarding a chest tube is that the chest tube drainage system must be placed below the site of insertion.
