What is the major criterion for diagnosing cognitive impairment in a child?
- A. An IQ of 75 or less
- B. Subaverage functioning
- C. An IQ of 70 or less
- D. Onset before 18
Correct Answer: C
Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

Which nursing intervention promotes achievement of the goal 'optimal mobility' for a client who had a total hip replacement 8 hours ago?
- A. Encourage the client to use an abductor pillow when ambulating.
- B. Teach the client to perform leg exercises in bed.
- C. Assist the client to sit at the edge of the bed.
- D. Assist the client to turn while an abductor pillow is between the legs.
Correct Answer: D
Rationale: Assisting the client to turn while an abductor pillow is between the legs is the correct intervention to promote optimal mobility for a client who had a total hip replacement 8 hours ago. Using an abductor pillow helps maintain hip alignment and prevents dislocation, which are crucial considerations in the early postoperative period. Encouraging the client to use an abductor pillow when turning is more beneficial compared to the other options: teaching leg exercises in bed, encouraging the use of a walker when ambulating, or assisting the client to sit at the edge of the bed, as these interventions may not directly address the specific needs of a client after a total hip replacement.
What is the main characteristic of cystic fibrosis?
- A. Multiple upper respiratory infections
- B. An underproduction of exocrine glands
- C. Excessive, thick mucus
- D. An overproduction of thin mucus
Correct Answer: C
Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.
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 nurse is triaging clients who have been injured during a tornado. Which client requires immediate action?
- A. A young male with a minor laceration on his forearm.
- B. An elderly woman with a dislocated shoulder who is calm.
- C. A middle-aged female with a broken humerus who is unable to follow commands and is crying.
- D. A teenager with abrasions and a bruised knee.
Correct Answer: C
Rationale: The middle-aged female with a broken humerus who is unable to follow commands and is crying requires immediate action. These symptoms indicate a possible head injury or severe emotional distress that need urgent attention. Choice A is not as urgent since a minor laceration can be addressed after more critical cases. Choice B, although having a dislocated shoulder, is stable, as the client is calm. Choice D presents with minor injuries that can wait while more critical cases are addressed.
After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?
- A. Reorient the client to the room
- B. Place an eye patch on one eye
- C. Evaluate the client's ability to swallow
- D. Perform range of motion exercises
Correct Answer: C
Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.
