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: A

Rationale: The correct answer is A: Assess airway. In caring for a client with a traumatic head injury, the first priority is to ensure there is a clear airway to maintain oxygenation and ventilation, which is crucial for brain function. If the airway is compromised, it can lead to hypoxia and further brain damage. Providing pain relief (B) is important but not the immediate priority. Monitoring intracranial pressure (C) is essential but comes after ensuring a patent airway. Maintaining a quiet environment (D) can help reduce stimulation, but it is not as critical as assessing the airway for immediate intervention.

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: Tenderness, warmth, and swelling at the site. Post-operative wound infection often presents with localized tenderness, warmth, and swelling due to inflammation and immune response. Redness, heat, and purulent drainage (choice A) can also indicate infection but are not specific to wound infections. Excessive swelling and redness (choice C) may be present in inflammatory responses but do not specifically point to an infection. Fever, chills, and nausea (choice D) can be systemic signs of infection but are not specific to wound infections. Tenderness, warmth, and swelling are more indicative of a localized wound infection.

Correct Answer: D

Rationale: The correct answer is D (Morton's neuroma) because interventions for difficulty walking due to a foot mass include recommending proper footwear, orthotic devices, corticosteroid injections, physical therapy, and in severe cases, surgical removal of the mass. Morton's neuroma causes pain and tingling in the ball of the foot, leading to difficulty walking. Plantar fasciitis (A), Hallux valgus (B), and Hammertoe (C) do not typically present with a mass in the foot causing difficulty walking.
