After a total hip replacement, the hip cannot be bent or flexed more than ______ degrees.
- A. 45
- B. 75
- C. 90
- D. 100
Correct Answer: C
Rationale: The correct answer is C - 90 degrees. After a total hip replacement, the hip should not be bent or flexed more than 90 degrees to prevent dislocation of the prosthetic hip joint. This restriction helps maintain the stability of the joint and prevent complications. Choices A, B, and D are incorrect because bending the hip beyond 90 degrees can increase the risk of dislocation and compromise the integrity of the implant. It is essential to follow these restrictions post-surgery to ensure proper healing and function of the hip joint.

Which of the following is the normal temperature range for the oral method?
- A. 96-96 degrees F
- B. 96-96 degrees F
- C. 96-99 degrees F
- D. 96-06 degrees F
Correct Answer: A
Rationale: The correct answer is A (96-99 degrees F). The normal oral temperature range for adults is typically between 97-99 degrees F. Answer B is the same as answer A, which is incorrect. Answer C (96-99 degrees F) falls within the normal range. Answer D (96-06 degrees F) is incorrect as it includes a temperature of 06 degrees F, which is not a realistic or safe temperature for a living human being. Therefore, the correct answer is A because it accurately reflects the normal temperature range for the oral method.

A common treatment for anemia is
- A. Reducing vitamin intake
- B. Increasing iron intake
- C. Injections of vitamin K
- D. Decreasing fiber in the diet
Correct Answer: B
Rationale: The correct answer is B: Increasing iron intake. Iron is essential for the production of hemoglobin, which carries oxygen in red blood cells. Anemia is often due to an iron deficiency, so increasing iron intake helps replenish iron stores and improve red blood cell production. Reducing vitamin intake (A) is not recommended as vitamins play a crucial role in overall health. Injections of vitamin K (C) are not typically used to treat anemia. Decreasing fiber in the diet (D) is unrelated to anemia and can even worsen the condition by limiting nutrient absorption.
