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: C

Rationale: The correct answer is C: Ensure the lens is centered on the cornea. This is important because removing a hard contact lens that is not centered can cause damage to the cornea or surrounding structures. By ensuring the lens is properly positioned on the cornea before attempting removal, the risk of injury is minimized. Explanation of other choices: A: Gently irrigating the eye with solution is not the correct procedure for removing hard contact lenses as it does not address the specific task of lens removal. B: Grasping the lens with a gentle pinching motion can be harmful if the lens is not centered, leading to potential damage to the eye. D: Using sterile gloves before attempting removal is important for hygiene but does not directly affect the safe removal of hard contact lenses from an unresponsive client.

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: The correct answer is B: Apply sterile dressings. This is the priority nursing intervention for a client with a deep wound infection because it helps prevent further contamination and promotes wound healing. Sterile dressings create a barrier against external pathogens and keep the wound environment clean, which is crucial in managing infections. Administering IV antibiotics (choice A) may be necessary but treating the wound first is essential. Applying heat to the wound (choice C) can worsen the infection by promoting bacterial growth. Administering IV fluids (choice D) may be needed for hydration but is not the priority in managing a deep wound infection.

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.
