Correct Answer: C

Rationale: Bursitis is characterized by inflammation of the bursa, which is a small, fluid-filled sac that cushions and reduces friction between bones, tendons, and muscles near joints. In the shoulder, bursitis commonly affects the subacromial bursa, located between the rotator cuff tendons and the top of the shoulder blade. The inflammation of this bursa can lead to pain and restricted movement around the shoulder joint.

Correct Answer: D

Rationale: Acute respiratory distress syndrome (ARDS) is a severe condition characterized by widespread inflammation in the lungs leading to increased pulmonary vascular permeability, non-cardiogenic pulmonary edema, and respiratory failure. In ARDS, the alveolar-capillary barrier is disrupted, resulting in fluid accumulation in the alveoli and impaired gas exchange.

Correct Answer: A

Rationale: Maternal dehydration can contribute to a prolonged latent phase during labor. Dehydration can lead to reduced blood volume and electrolyte imbalances, which can result in ineffective uterine contractions. Without adequate hydration, the uterus may not contract effectively, causing irregular and infrequent contractions. It is important for the nurse to assess the woman's hydration status and encourage her to stay hydrated during labor to help regulate contractions and progress labor.

Correct Answer: C

Rationale: The appropriate ratio of chest compressions to rescue breaths for adult CPR is 30 compressions to 2 breaths. This means that after every 30 chest compressions, two rescue breaths should be given. This ratio helps in maintaining oxygen circulation in the body while also ensuring that the heart is being effectively pumped to circulate blood. The emphasis on chest compressions is critical in maintaining blood flow to vital organs during cardiac arrest, while the rescue breaths help in providing oxygen to the patient's lungs. This ratio is recommended by organizations like the American Heart Association for performing high-quality adult CPR.
