Correct Answer: A

Rationale: The correct answer is A, contusion. A contusion is a soft-tissue injury caused by blunt force resulting in bruising, without breaking the skin. This is different from the other choices. Strain (B) refers to an injury to a muscle or tendon due to overstretching. Sprain (C) is an injury to a ligament from overstretching. Dislocation (D) involves the displacement of bones at a joint, not a soft-tissue injury. Therefore, the term that specifically aligns with a soft-tissue injury from blunt force is contusion.

Correct Answer: D

Rationale: The correct answer is D: Administer diuretics. The priority for a nurse caring for a client with pneumonia is to maintain adequate oxygenation and prevent respiratory failure. Diuretics help reduce fluid overload in the lungs, improving gas exchange and oxygenation. Administering antibiotics (choice A) is important to treat the infection but not the top priority. Administering oxygen (choice B) is crucial for oxygenation, but diuretics take precedence to improve lung function. Administering corticosteroids (choice C) may be considered in certain cases to reduce inflammation, but it is not the primary priority.

Correct Answer: B

Rationale: Rationale: 1. pH within normal range (7.35-7.45) indicates homeostasis. 2. PO2 (normal 75-100 mmHg) and PCO2 (normal 35-45 mmHg) are slightly deviated but not clinically significant. 3. HCO3 within normal range (22-26 mEq/L) further supports overall balance. Summary: A: Incorrect - HCO3 level is within normal range, ruling out metabolic alkalosis. C: Incorrect - PCO2 is within normal range, ruling out respiratory acidosis. D: Incorrect - PCO2 is slightly low but not significantly, ruling out respiratory alkalosis. Overall, the ABG values indicate the body is in homeostasis.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. During an acute asthma attack, the priority intervention is to immediately open the airways to improve breathing. Bronchodilators, such as albuterol, work rapidly to dilate the bronchioles and relieve bronchospasms, making it the most effective initial treatment. Corticosteroids (B) are used for long-term control, not immediate relief. Applying oxygen and administering albuterol (C) is close, but bronchodilators should be given first for quicker relief. Applying a cold compress (D) is not appropriate for managing an asthma attack.

Correct Answer: C

Rationale: Rationale: Choice C, apply ice, is the correct answer as the first intervention for a client at risk for dehydration. Applying ice helps to lower the body temperature, which can reduce sweating and fluid loss. This intervention is crucial in preventing further dehydration. Administering IV fluids (Choice A) may be necessary in severe dehydration cases, but it is not the first intervention. Administering oxygen (Choice B) is not directly related to dehydration. Elevating the leg (Choice D) is not effective in addressing dehydration. In summary, applying ice is the most appropriate initial intervention to prevent dehydration by reducing body temperature and fluid loss.
