Correct Answer: C

Rationale: The correct answer is C because it addresses the specific nursing intervention needed to prepare Mr. RR for the brain scanning test. By explaining to Mr. RR that the test will not be painful and that his head will be supported in place, the nurse helps alleviate any potential anxiety or fear he may have. This information reassures the patient and ensures his cooperation during the procedure. Choice A is incorrect because discontinuing anticonvulsant therapy without medical approval could have serious consequences for Mr. RR's health. Choice B is also incorrect as obtaining consent is important, but it is not directly related to preparing Mr. RR for the test. Choice D is incorrect as it introduces potential negative outcomes without providing necessary information to prepare the patient for the test.

Correct Answer: A

Rationale: The correct answer is A: Type A. Individuals with blood type A have a slightly higher risk of developing gastric cancer compared to other blood types. This is due to the presence of certain antigens associated with Type A blood that may increase susceptibility to gastric cancer. In this case, the nurse mentions a 10% increased risk for individuals with Type A blood, which aligns with the known epidemiological data. Choice B: Type AB is incorrect because individuals with Type AB blood do not have a known increased risk of gastric cancer. Choice C: Type B is incorrect because individuals with Type B blood do not have a known increased risk of gastric cancer. Choice D: Type O is incorrect because individuals with Type O blood actually have a slightly lower risk of developing gastric cancer compared to individuals with Type A blood.

Correct Answer: D

Rationale: The correct answer is D: Risk for body image disturbance. In the context of Maslow's hierarchy of needs, physiological needs take precedence over psychological needs. For a client in the intensive care unit with congestive heart failure, ensuring physiological needs like airway clearance, urinary elimination, and coping are addressed first is crucial for survival. Body image disturbance is a higher-level psychological need and can be addressed once basic physiological needs are met. Therefore, addressing the risk for body image disturbance would have the lowest priority compared to the other options provided.

Correct Answer: B

Rationale: The correct answer is B: "Keep the stoma dry." Keeping the stoma dry helps prevent infection and skin irritation. Moisture can lead to fungal growth and skin breakdown. Option A is incorrect because keeping the stoma uncovered can increase the risk of contamination and infection. Option C is incorrect as self-care promotes independence and allows the client to become familiar with the procedure. Option D is incorrect as moisture can lead to skin issues.

Correct Answer: C

Rationale: The correct answer is C: 10 to 15 g of a simple carbohydrate. This amount of carbohydrate is recommended for treating hypoglycemia in clients with diabetes to quickly raise blood glucose levels without causing hyperglycemia. Consuming too little carbohydrate may not effectively raise blood glucose levels, while consuming too much may lead to a rapid spike followed by a rebound hypoglycemia. Options A and B provide insufficient amounts of carbohydrate, while option D provides excessive carbohydrate, increasing the risk of hyperglycemia. Therefore, option C is the most appropriate choice for effectively treating hypoglycemia in this client.
