1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. The nurse is caring for a post-surgical client at risk for developing deep vein thrombosis. Which intervention is an effective preventive measure?

Correct answer: B

Rationale: Encouraging range of motion and ambulation is an effective preventive measure for deep vein thrombosis in post-surgical clients. Mobility helps improve blood circulation, reducing the risk of clot formation. Elastic stockings help prevent blood pooling and clotting in the legs by providing external pressure to support venous return. Massaging the legs twice daily may help with circulation but is not as effective as promoting movement and ambulation. Placing pillows under the knees is a comfort measure and does not directly address the prevention of deep vein thrombosis.

3. A mother brings her child to the well-child clinic and expresses concern to the nurse because the child has been playing with another child diagnosed with hepatitis. The nurse prepares to perform an assessment on the child, knowing that which finding would be of least concern for hepatitis?

Correct answer: D

Rationale: Assessment findings in a child with hepatitis typically include right upper quadrant tenderness and hepatomegaly. The child may also present with pale, clay-colored stools and dark, frothy urine. Jaundice, which can be observed in the sclerae, nail beds, and mucous membranes, is a common sign of hepatitis. Left upper abdominal quadrant pain is not a typical finding associated with hepatitis; therefore, it would be of least concern in this scenario. The other options are more commonly associated with hepatitis and are important signs to monitor for in a child with possible exposure to the virus.

4. Parents of a 6-month-old breastfed baby ask the nurse about increasing the baby's diet. Which of the following should be added first?

Correct answer: A

Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.

5. A client in end-stage renal disease is receiving peritoneal dialysis at home. The nurse must educate the client about potential complications associated with this procedure. All of the following are complications associated with peritoneal dialysis EXCEPT:

Correct answer: A

Rationale: Peritoneal dialysis poses risks of various complications, including abdominal hernia, anorexia, peritonitis, and other issues. However, hypotriglyceridemia is not a common complication associated with peritoneal dialysis. The nurse should focus on educating the client about the risks of developing peritonitis, abdominal hernias, anorexia, low back pain, and abdominal bleeding. Monitoring triglyceride levels is essential for managing lipid disorders but is not directly linked to peritoneal dialysis complications.
