Which statement would indicate that the parents of child with cystic fibrosis understand the disorder?

“There are fibrous cysts in the lungs."

"The mucus-secreting glands are abnormal."

"Allergic reactions cause inflammation in the lungs."

"Early treatment can stop the progression of the disease."

Answer and Explanation

The Correct Answer is B

A. "There are fibrous cysts in the lungs.": While lung damage and scarring (fibrosis) occur in cystic fibrosis, the primary issue is the abnormal mucus, not the presence of pre-existing fibrous cysts. Cystic fibrosis does not involve actual fibrous cysts in the lungs but rather thick, sticky mucus that clogs airways and promotes infection.
B. "The mucus-secreting glands are abnormal.": Cystic fibrosis is a genetic disorder that affects exocrine glands, leading to abnormally thick and sticky mucus. This affects the lungs, pancreas, and other organs, making this statement accurate.
C. "Allergic reactions cause inflammation in the lungs.": Cystic fibrosis is not caused by allergies or immune responses. Lung damage results from mucus accumulation and chronic infections, not allergic inflammation.
D. "Early treatment can stop the progression of the disease.": Early treatment can slow progression and improve quality of life but cannot stop the disease. Cystic fibrosis remains a lifelong, progressive condition despite medical advances.

Correct Answer is A

Explanation

A. Alveoli: The alveoli are responsible for gas exchange, including the removal of CO₂. Impaired alveolar function leads to CO₂ retention and respiratory acidosis, commonly seen in conditions like COPD or pneumonia.
B. The pulmonary artery: The pulmonary artery carries deoxygenated blood to the lungs but does not directly participate in gas exchange. Impairment here affects perfusion, not CO₂ elimination.
C. The pulmonary vein: The pulmonary vein returns oxygenated blood to the heart and is not involved in gas exchange. Elevated CO₂ is not typically linked to vein function.
D. Bronchi: The bronchi conduct air but do not facilitate gas exchange. While obstruction can contribute to CO₂ retention, the alveoli are primarily responsible for its removal.

A. Placing gel on the chest B. Shouting, "All clear" C. Stating, "Charging" D. Checking the ECG rhythm

Correct Answer is B

Explanation

A. Placing gel on the chest: Applying gel or using pre-gelled pads is done early in the preparation process. While important for conductivity, it does not directly precede defibrillation.
B. Shouting, "All clear": Before delivering a shock, the nurse must ensure no one is in contact with the client or bed to prevent accidental injury. Shouting "All clear" is a critical safety step that immediately precedes pressing the discharge button.
C. Stating, "Charging": Announcing "Charging" is done just before preparing to shock, but it occurs prior to confirming that everyone is clear of the client. It does not directly precede defibrillation.
D. Checking the ECG rhythm: Assessing the rhythm is essential to confirm that defibrillation is indicated (e.g., for ventricular fibrillation or pulseless VT), but it is completed well before the final discharge step.
