Correct Answer: B

Rationale: The correct answer is B because encouraging the patient to do leg exercises within the limits of his traction promotes independence by maintaining muscle strength and mobility. This helps prevent muscle atrophy and promotes circulation. Choice A focuses on pain management but does not directly promote independence. Choice C provides assistance but does not actively involve the patient in self-care. Choice D is important for overall care but does not directly promote independence through active patient involvement.

Correct Answer: D

Rationale: The correct answer is D: Wheezing. Anaphylaxis is a severe allergic reaction that can lead to airway constriction and difficulty breathing, resulting in wheezing. Wheezing is a common symptom of anaphylaxis due to bronchospasm and airway swelling. Dermatitis (A) is a skin reaction, sinusitis (B) is inflammation of the sinuses, and delirium (C) is a state of mental confusion, which are not typical symptoms of anaphylaxis. Wheezing is a critical symptom in anaphylaxis as it indicates potential airway compromise and the need for immediate medical intervention.

Correct Answer: A

Rationale: The correct answer is A because auscultation of the lungs involves direct observation and measurement, making it objective data. This data is based on what the nurse hears through the stethoscope, which can be verified and measured. Choices B, C, and D involve subjective experiences or interpretations that cannot be directly observed or measured. Complaint of nausea, sensation of burning, and belief in demons are all based on the client's feelings, perceptions, or beliefs, which are subjective and can vary from person to person. Objective data is factual, measurable, and observable, making choice A the correct answer in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Decreased gastrointestinal motility. This is the defining characteristic because it directly links the cause (pain medication administration) to the effect (constipation). The patient's lack of bowel movement, abdominal distention, and pain are all consequences of decreased gastrointestinal motility. Pain medication slows down the movement of the intestines, leading to constipation. Choices B, C, and D are incorrect because while they are related to the patient's condition, they are not the defining characteristic that connects the cause to the effect in this specific scenario.

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.
