Correct Answer: C

Rationale: Gangrene refers to dead, blackened tissue, often a result of chronic ischemia in clients with peripheral vascular disease. Atrophy (Choice A) is the wasting away or decrease in size of tissue or organ. Contraction (Choice B) refers to the shortening or tightening of a muscle or other body part. Rubor (Choice D) is a red discoloration of the skin, often associated with inflammation or poor circulation, but not typically presenting as blackening like gangrene.

Correct Answer: D

Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.

Correct Answer: A

Rationale: During seizures in an unconscious client, ensuring oral suction is available is crucial to managing secretions and preventing aspiration. This intervention helps maintain a clear airway and reduce the risk of complications. Maintaining the client in a semi-Fowler's position (Choice B) may be important for airway management but is not as critical as having oral suction ready. Providing frequent mouth care (Choice C) and keeping the room at a comfortable temperature (Choice D) are important aspects of overall care but are not as urgently needed as ensuring oral suction for managing secretions during seizures.

Correct Answer: A

Rationale: A high-fiber diet with increased fluid intake is the most appropriate diet instruction for a client diagnosed with diverticulosis. High-fiber foods help prevent constipation and promote bowel regularity, reducing the risk of complications such as diverticulitis. Adequate fluid intake is crucial to soften stool and aid in digestion. Choice B, having small frequent meals and sitting up after meals, may be beneficial for some gastrointestinal conditions but is not specific to diverticulosis. Choice C, eating a bland diet and avoiding spicy foods, is not necessary for diverticulosis management. Choice D, consuming a soft diet with increased milk and milk products, may worsen symptoms in diverticulosis due to the potential for increased gas production and bloating.

Correct Answer: B

Rationale: In this scenario, the priority intervention for the nurse is to offer support and care measures to reduce anxiety and stress. Addressing the client's emotional distress is crucial as the stress can exacerbate adrenal insufficiency. While teaching the client about the risk for infection (Choice A) is important, addressing the immediate emotional needs takes precedence. Encouraging the client to rest quietly (Choice C) is beneficial but does not directly address the client's current distress about job loss. Referring the client to social services (Choice D) for financial options is important, but at this moment, addressing the client's anxiety is the priority to promote emotional well-being.
