Nokea
A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?
- A. Inflammation of the synovial membrane.
- B. Degeneration of the cartilage in the joint.
- C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
- D. Formation of uric acid crystals in the joint space.
Correct Answer: C
Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

A client who has a history of hyperthyroidism was initially admitted with lethargy and confusion. Which additional finding warrants the most immediate action by the nurse?
- A. Facial puffiness and periorbital edema
- B. Hematocrit of 30%
- C. Cold and dry skin
- D. Further decline in LOC
Correct Answer: D
Rationale: A further decline in LOC can indicate severe complications and requires immediate attention. This change may signify worsening neurological status, which could lead to life-threatening consequences if not addressed promptly. Choices A, B, and C may also be concerning in a client with a history of hyperthyroidism, but a further decline in LOC takes priority due to its potential for rapid deterioration and the need for urgent intervention.
A teenage girl has been placed in a brace for the treatment of scoliosis, the most common skeletal deformity of adolescence. The family asks what they can do to be more supportive. What suggestion from the nurse is the most appropriate?
- A. Enrolling her in a health club
- B. Taking her to the mall in a wheelchair
- C. Purchasing clothes to disguise the brace
- D. Spending a majority of their time with her
Correct Answer: C
Rationale: The most appropriate suggestion from the nurse is to recommend purchasing clothes to disguise the brace. Adolescents with scoliosis often have body image concerns and wish to fit in with their peers. By providing clothes that help conceal the brace, the family can support the teenage girl's emotional well-being. Choices A, B, and D do not directly address the adolescent's concerns about body image and fitting in, making them less appropriate in this situation.
A client with deep vein thrombosis (DVT) is being treated with warfarin. Which dietary instruction should the nurse provide?
- A. Avoid foods high in vitamin C
- B. Increase intake of green leafy vegetables
- C. Limit intake of foods high in vitamin K
- D. Avoid dairy products
Correct Answer: C
Rationale: The correct answer is C: 'Limit intake of foods high in vitamin K'. Vitamin K can interfere with the effectiveness of warfarin, an anticoagulant medication commonly used to treat conditions like deep vein thrombosis (DVT). Patients on warfarin should maintain a consistent intake of vitamin K-rich foods and be monitored closely. Choices A, B, and D are incorrect because avoiding foods high in vitamin C, increasing intake of green leafy vegetables, and avoiding dairy products are not essential dietary instructions for a client on warfarin therapy for DVT.
The mother of a child with acute laryngotracheobronchitis (LTB) asks why her child must be kept NPO. Which response would be the most correct?
- A. The epinephrine given causes nausea and vomiting.
- B. The child is being hydrated with IV fluids.
- C. The child is not hungry.
- D. The child's rapid respirations pose a risk for aspiration.
Correct Answer: D
Rationale: The correct answer is D because rapid respirations predispose to aspiration in a child with acute laryngotracheobronchitis. Choice A is incorrect because epinephrine does not directly relate to the need for NPO status. Choice B is incorrect as hydration with IV fluids is not the primary reason for keeping the child NPO. Choice C is incorrect as the child being hungry is not the main concern when keeping a child NPO in this situation.
A male client with diabetes mellitus is transferred from the hospital to a rehabilitation facility following treatment for a stroke resulting in right hemiplegia. He tells the nurse that his feet are always uncomfortably cool at night, preventing him from falling asleep. Which action should the nurse implement?
- A. Provide a warming pad for his feet
- B. Medicate the client with a prescribed sedative.
- C. Use a bed cradle to keep the covers off his feet.
- D. Place warm blankets next to the client's feet.
Correct Answer: D
Rationale: Placing warm blankets next to the client's feet is the most appropriate action to provide warmth and comfort. This method is safe and effective in addressing the client's complaint of uncomfortably cool feet at night. Providing a warming pad (Choice A) may pose a risk of burns or injury, especially for a client with decreased sensation due to diabetes. Mediating the client with a sedative (Choice B) does not address the underlying issue of cool feet and may not be necessary. Using a bed cradle (Choice C) to hold the covers off the feet does not directly address the client's need for warmth and comfort.
