Correct Answer: D

Rationale: The correct instruction for a UAP caring for a client with MRSA under contact precautions is to don a gown and gloves when entering the client's room. This precaution is essential to prevent the spread of MRSA and protect both the client and the healthcare worker from potential infection. Choice A is incorrect because visitors should not be restricted solely based on contact precautions. Choice B is incorrect as wearing sterile gloves is not necessary, standard precautions with regular gloves are sufficient. Choice C is incorrect because the client wearing a mask is not a standard practice for contact precautions; it is the healthcare worker who should take preventive measures.

Correct Answer: A

Rationale: The most appropriate position for a client following abdominal surgery is Semi-Fowler's. This position promotes greater thoracic expansion and reduces pressure on the suture line, aiding in respiratory function and preventing strain on the incision site. Choices B, C, and D are incorrect. Prone position (Choice B) would not be suitable after abdominal surgery as it can put pressure on the abdomen. Supine position (Choice C) may cause discomfort and strain on the incision area. Sim's position (Choice D) is primarily used for rectal exams and enemas, which are unrelated to the needs post-abdominal surgery.

Correct Answer: B

Rationale: Hinge joints, like the elbow, primarily allow movement in one direction, in this case, bending the arm. The correct action to exercise hinge joints is to bend the arm by flexing the ulnar to the humerus. This movement specifically targets the hinge joint and promotes its range of motion. Choices A, C, and D involve movements that do not specifically target hinge joints. Tilt the pelvis involves the ball-and-socket joints of the hip, turning the head involves the pivot joint of the neck, and extending the arm and rotating it in circles involve multiple joints including ball-and-socket and pivot joints.

Correct Answer: C

Rationale: Limiting saturated fat from animal food sources to no more than 4 ounces per week is an important diet modification for lowering cholesterol. To be effective in reducing cholesterol, the client should exercise 30 minutes per day, or at least 4 to 6 times per week. Red meat and all proteins do not need to be eliminated to lower cholesterol, but should be restricted to lean cuts of red meat and smaller portions. The low density lipoproteins need to decrease rather than increase.

Correct Answer: A

Rationale: To prevent the risk of suffocation, soft blankets are preferred over pillows for padding side rails in clients with seizure disorders. Pillows can pose a suffocation hazard, especially during a seizure episode when the client's movements may be uncontrolled. Instructing the UAP to use soft blankets instead of pillows is crucial for ensuring the client's safety. Choice B is incorrect because pillows can be hazardous during a seizure. Choice C is incorrect as side-lying position may not be appropriate for a client with a seizure disorder. Choice D is incorrect as it does not address the safety concern related to using pillows.
