Correct Answer: C

Rationale: The correct nursing diagnosis is C: Impaired skin integrity. This choice is correct because it directly addresses the bacterial infection in the left lower leg by focusing on the skin's condition. The patient's skin integrity is compromised due to the infection, making this nursing diagnosis appropriate. Choice A (Infection) is too broad and does not specify the impact on the skin. Choice B (Risk for infection) is incorrect because the patient already has a bacterial infection, so the risk has already manifested. Choice D (Staphylococcal leg infection) is too specific and does not address the broader issue of skin integrity. Therefore, the best choice is C as it accurately reflects the patient's current condition and guides appropriate nursing interventions to address the impaired skin integrity caused by the bacterial infection.

Correct Answer: A

Rationale: The correct answer is A: Bacterial meningitis. Bacterial meningitis is the most significant form due to its potential severity and rapid progression, requiring urgent medical intervention with antibiotics. Bacterial meningitis can lead to serious complications such as brain damage or death if left untreated. Septic meningitis (choice B) refers to meningitis caused by a systemic infection spreading to the meninges. Aseptic meningitis (choice C) is typically viral or non-bacterial in origin, usually milder than bacterial meningitis. Viral meningitis (choice D) is less severe than bacterial meningitis and often resolves on its own without specific treatment.

Correct Answer: A

Rationale: The correct answer is A because bodily fluids and excretions (urine, feces, vomitus) can become contaminated with radiation from the implant. Therefore, they should be considered highly radioactive and handled appropriately. Choice B is incorrect because the client may remain radioactive for a longer period than 10 days post-implant removal. Choice C is incorrect because soiled linens should be handled according to radiation safety protocols and removed promptly. Choice D is incorrect because bed rest is not necessary unless specifically indicated by the healthcare provider; the client should be encouraged to move around as tolerated to prevent complications.

Correct Answer: B

Rationale: The correct answer is B: Levodopa. Levodopa is associated with the on-off phenomenon and wearing-off effect in Parkinson's disease treatment due to fluctuations in its effectiveness over time. The on-off phenomenon refers to sudden and unpredictable changes in motor function, while wearing-off effect occurs when the medication's effects diminish before the next dose. Amantadine (A) is not typically associated with these phenomena. Benztropine (C) is an anticholinergic used for tremors and rigidity. Pramixole (D) is a dopamine agonist that can cause dyskinesias but is not primarily linked to on-off or wearing-off effects.

Correct Answer: C

Rationale: The correct answer is C: Auscultate lung sounds. By auscultating lung sounds, the nurse can assess for changes in breath sounds which can indicate improvement or deterioration in the patient's condition. This helps monitor the effectiveness of therapy for a pneumothorax and chest-drainage system. Palpating for crepitus (A) is not directly related to monitoring therapy effectiveness. Documenting sputum color and amount (B) is important but does not specifically monitor therapy effectiveness. Monitoring suction level (D) is crucial but does not directly assess the patient's response to therapy.
