Correct Answer: A

Rationale: The correct intervention in managing a patient with diabetic ketoacidosis (DKA) is to administer insulin and fluids. Insulin is crucial to correct hyperglycemia, while fluids are important to address dehydration. Administering oral hypoglycemics (Choice B) is not appropriate in the management of DKA as the patient may not be able to absorb oral medications due to gastrointestinal issues. Glucagon (Choice C) is not indicated in the treatment of DKA. Although monitoring blood glucose (Choice D) is important, it is not the sole key intervention for managing DKA; administering insulin and fluids are the primary interventions.

Correct Answer: C

Rationale: When caring for a client diagnosed with delirium, the most important condition for the nurse to investigate is prescription drug intoxication. Delirium can be caused by various factors, and prescription drug intoxication is a common reversible cause. Investigating this factor first is crucial to identify and address the underlying cause promptly. Choices A, B, and D are less likely to be directly associated with delirium compared to prescription drug intoxication. While cancer, impaired hearing, and heart failure can have their complications and effects, they are not typically the primary causes of delirium in a client.

Correct Answer: B

Rationale: The correct answer is to reduce caffeine and alcohol intake for a client with hypertension. Caffeine and alcohol can increase blood pressure, so reducing their intake can help manage hypertension. Increasing sodium intake (Choice A) is not recommended for hypertension as it can lead to fluid retention and increased blood pressure. Eating carbohydrate-rich meals (Choice C) is also not ideal as excessive carbohydrates can contribute to weight gain, which can worsen hypertension. Similarly, increasing protein intake (Choice D) is not a primary focus for managing hypertension unless a specific protein deficiency is present.

Correct Answer: D

Rationale: The nurse should first ask the client where the pain is located because identifying the location of the pain is crucial in determining the cause and appropriate treatment. This information helps in further assessment and diagnosis. Asking when the pain started (Choice A) may be important but determining the location provides more immediate insights. Inquiring about the severity of pain (Choice B) and what worsens it (Choice C) are also important but come after identifying the location to provide a comprehensive understanding of the client's condition.

Correct Answer: B

Rationale: The correct answer is B: Antiplatelet. Aspirin works by inhibiting platelet aggregation, making it an antiplatelet agent. This effect helps reduce the risk of blood clot formation in clients with CAD. Choice A, Analgesic, is incorrect because aspirin's primary action in this context is not pain relief. Choice C, Anticoagulant, is incorrect as aspirin does not directly inhibit coagulation factors. Choice D, Thrombolytic, is incorrect as aspirin does not actively break down clots but rather prevents their formation.
