Correct Answer: B

Rationale: The correct first action for the nurse to take in this scenario is to obtain a clean-catch midstream urine specimen. The client's symptoms of confusion, nausea, dysuria, and urgency are suggestive of a urinary tract infection (UTI). To confirm the diagnosis and identify the causative organism, a urine specimen should be collected before initiating any treatment. Initiating intravenous fluids (Choice A) may be necessary later based on the client's condition but is not the initial priority. Administering antibiotics (Choice C) should be done after confirming the diagnosis through urine culture. Starting a Foley catheter (Choice D) to obtain a sterile sample is more invasive and should not be the first step in the assessment and management of a suspected UTI.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client receiving IV antibiotics for sepsis reports itching and a rash on the chest is to stop the infusion and notify the healthcare provider. This is crucial in preventing the allergic reaction from worsening. Administering an antihistamine (choice A) may address the symptoms but does not address the primary concern of stopping the infusion. Slowing the infusion rate and monitoring the client (choice C) may not be sufficient if the reaction is severe. Administering epinephrine subcutaneously (choice D) is not the first-line intervention for this situation.

Correct Answer: D

Rationale: The correct answer is D: 'Eat potassium-rich foods like bananas and oranges.' Thiazide diuretics can lead to potassium loss, so it is essential for clients to consume potassium-rich foods to maintain adequate levels. Choice A is incorrect because focusing solely on low carbohydrates and fats does not address the specific issue of potassium loss. Choice B is unrelated as vitamin K content is not a concern with thiazide diuretics. Choice C is incorrect as increasing salt intake would exacerbate hypertension and not prevent dehydration.

Correct Answer: A

Rationale: The correct answer is to monitor for signs of infection. Redness and swelling around a wound are indicative of a potential infection. The priority intervention for the nurse is to closely monitor the wound for further signs of infection, such as increased drainage or fever. Reinforcing the wound dressing may be necessary, but it is not the priority when infection is suspected. Contacting the healthcare provider is important, but the nurse should first assess and monitor the wound to provide comprehensive information when contacting the provider. Applying a warm compress can potentially worsen the infection by promoting bacterial growth, so it is contraindicated in this situation.

Correct Answer: B

Rationale: The correct answer is B. Clients with duodenal ulcers should avoid spicy foods and alcohol as they can exacerbate symptoms and delay healing. Choice A is incorrect because while antacids may help with symptoms, they are not the primary focus of medication teaching for duodenal ulcers. Choice C is not directly related to medication teaching for duodenal ulcers unless antibiotics are specifically prescribed. Choice D is incorrect as stopping all food intake is not recommended and can lead to other complications.
