Adult Health 2 Exam 1

Correct Answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

Correct Answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

Correct Answer: B

Rationale: The correct answer is B: 'Expect stools to be dark in color.' Dark stools are a common side effect of iron supplementation due to the unabsorbed iron, and this is not a cause for concern. Choice A is incorrect because taking iron with milk can decrease its absorption due to calcium binding. Choice C is incorrect as there are no specific recommendations to take ferrous sulfate before bedtime. Choice D is also incorrect as vitamin C actually enhances iron absorption and should not be avoided.

Correct Answer: C

Rationale: Rebound tenderness at McBurney's point is a classic sign of appendicitis. This symptom is due to irritation of the peritoneum when pressure is released during palpation. Right upper quadrant pain (Choice A) is more commonly associated with gallbladder issues. Nausea and vomiting (Choice B) can occur in various abdominal conditions and are not specific to appendicitis. Hematuria (Choice D) is the presence of blood in the urine and is not a typical symptom of appendicitis.

Correct Answer: B

Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
