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

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

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 reviewing the record of a child diagnosed with nephrotic syndrome. The nurse should expect to note which finding documented in the child's record?

• A. Polyuria
• B. Weight gain
• C. Hypotension
• D. Grossly bloody urine

Correct answer: B

Rationale: In nephrotic syndrome, a key finding documented in the child's record is weight gain due to massive edema. While urine may appear dark, foamy, and frothy, grossly bloody urine is not expected as only microscopic hematuria is present. Additionally, urine output is decreased, and hypertension is likely to be present. Therefore, the correct answer is weight gain as it aligns with the characteristic presentation of nephrotic syndrome.

3. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?

• A. Stroke volume
• B. Cardiac output
• C. Venous pressure
• D. Left ventricular functioning

Correct answer: D

Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.

4. 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:

• A. Hypotriglyceridemia
• B. Abdominal hernia
• C. Anorexia
• D. Peritonitis

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.

5. A nurse is caring for a patient with peripheral vascular disease (PVD). The patient complains of burning and tingling of the hands and feet and cannot tolerate touch of any kind. Which of the following is the most likely explanation for these symptoms?

• A. Inadequate tissue perfusion leading to nerve damage.
• B. Fluid overload leading to compression of nerve tissue.
• C. Sensation distortion due to psychiatric disturbance.
• D. Inflammation of the skin on the hands and feet.

Correct answer: A

Rationale: Patients with the peripheral vascular disease often sustain nerve damage as a result of inadequate tissue perfusion. Ischemic rest pain is more worrisome; it refers to pain in the extremity that is due to a combination of PVD and inadequate perfusion. Ischemic rest pain often is exacerbated by poor cardiac output. The condition is often partially or fully relieved by placing the extremity in a dependent position, so that perfusion is enhanced by the effects of gravity.
