Left Ventricle

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 A

Explanation

Pulse oximetry is a non-invasive method of monitoring the oxygen saturation level in the blood. A normal range for oxygen saturation is between 95% and 100%. An oxygen saturation level of 89% indicates hypoxemia, which is a serious condition that can lead to tissue damage, organ failure, and even death if left untreated.

Therefore, the priority nursing action is to perform a respiratory assessment to determine the cause of the hypoxemia. This should include assessing the client's airway patency, breathing patern, lung sounds, and oxygen therapy if the client is already receiving it. The nurse should also observe for any signs of respiratory distress such as cyanosis, accessory muscle use, or difficulty breathing.

While it is important to document hypoxemia and report it to the healthcare provider, the priority at this time is to assess and intervene promptly to prevent further deterioration of the client's condition. Checking the placement of the pulse oximeter may be necessary if the reading is unreliable, but it is not the priority in this scenario.

A. Patient will exchange cigaretes for vaping in 5 days B. Patient will stop smoking cigaretes within 7 days C. Patient will smoke only a few cigaretes each day D. Patient will not smoke cigaretes while wearing oxygen

Correct Answer is D

Explanation

This outcome is the most appropriate because smoking can worsen COPD and lead to further respiratory complications, while oxygen is often used to help patients with COPD breathe more easily. Smoking while wearing oxygen can be very dangerous and increases the risk of fire and explosion. Therefore, the best expected outcome is for the patient to completely avoid smoking while wearing oxygen.

Option a is not a recommended solution since vaping may also worsen COPD symptoms and there is limited evidence of its safety in people with respiratory conditions. Option b is a good outcome, but it may not be achievable in such a short time frame. Option c is not an ideal outcome as even a few cigaretes can cause harm to the respiratory system, exacerbate symptoms, and slow down the healing process.
