ATI PN Comprehensive Predictor 2020

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.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with stomatitis due to chemotherapy is to encourage the client to eat soft foods. Soft foods help prevent further irritation to the already inflamed and sore oral mucosa. Providing lemon-glycerin swabs may further irritate the mucosa due to the acidic nature of lemon. Avoiding toothpaste is advisable as many toothpaste products contain ingredients that can aggravate stomatitis. Instructing the client to use a mouthwash containing alcohol is contraindicated as alcohol-based mouthwashes can be too harsh and drying for the already sensitive oral tissues.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial in identifying the specific infecting organism and choosing the most effective antibiotic treatment. Changing the dressing every 4 hours (choice A) may be too frequent and can disrupt the wound healing process. Cleansing the wound with alcohol-based solutions (choice C) can be too harsh and may delay healing. Applying a wet-to-dry dressing (choice D) can cause trauma to the wound bed and is not recommended for infected wounds.

Correct Answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium can be caused by various factors such as infections, medications, or metabolic imbalances. Addressing these underlying causes can help resolve delirium. Administering sedative medication (Choice A) can worsen delirium by further altering mental status. Providing a low-stimulation environment (Choice C) is helpful to manage delirium symptoms, but it is not the most important intervention. Increasing environmental stimulation (Choice D) is contraindicated in delirium as it can exacerbate confusion and agitation.

Correct Answer: A

Rationale: The correct answer is to administer insulin. In hyperglycemia, there is an excess of glucose in the blood, which needs to be lowered. Insulin is the primary medication used to lower blood glucose levels by facilitating the uptake of glucose into cells. Encouraging the client to exercise may further increase blood glucose levels due to the release of stress hormones, so it is not the priority. While staying hydrated is important, it will not directly address the high blood glucose levels seen in hyperglycemia. Glucagon is used to treat severe hypoglycemia, not hyperglycemia, so it is not the priority in this situation.
