ATI PN Comprehensive Predictor 2020

Correct Answer: D

Rationale: The nurse should prioritize performing a wound culture before administering antibiotics to ensure appropriate treatment. This step helps identify the specific infecting organism and its susceptibility to different antibiotics, guiding effective antibiotic therapy. Changing the dressing daily (Choice A) is important but comes after assessing the infection and initiating appropriate treatment. Cleansing the wound with an antiseptic solution (Choice B) and applying a wet-to-dry dressing (Choice C) are interventions that may be necessary but are secondary to determining the most suitable antibiotic therapy based on the wound culture results.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.

Correct Answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is an excess production of cortisol, leading to hyperglycemia. This results in an increase in serum glucose levels. Choices B, C, and D are incorrect because Cushing's disease does not directly affect serum calcium levels, lymphocyte count, or serum potassium levels.

Correct Answer: D

Rationale: After cataract surgery, it is essential to avoid lying on the affected side to reduce pressure and promote healing. Sleeping on the side of the affected eye (Choice C) may increase pressure on the eye, leading to complications. While using eye drops to soothe dryness (Choice A) is generally recommended postoperatively, it is not as crucial as avoiding pressure on the eye. Rubbing the eye (Choice B) should be avoided to prevent irritation and potential damage, but it is not as critical as avoiding pressure on the affected eye.

Correct Answer: C

Rationale: The correct answer is to instruct the client to use a soft toothbrush. Using a soft toothbrush helps prevent bleeding in clients receiving chemotherapy, who are at risk for mucositis. Encouraging the client to eat high-protein foods (Choice A) is important for overall health but not directly related to preventing infection. Encouraging the client to drink 2 liters of fluid daily (Choice B) is essential for hydration but does not specifically prevent infection. Instructing the client to use a mouthwash containing alcohol (Choice D) is contraindicated as alcohol-containing mouthwashes can cause irritation and dryness in the oral mucosa, increasing the risk of infection.
