1. A patient undergoing continuous ambulatory peritoneal dialysis (CAPD) reports feeling
a sudden onset of shoulder pain and shortness of breath immediately following the infusion
of 2000 mL of dialysate. What is the most appropriate initial nursing action?
A. Immediately drain the peritoneal cavity to relieve diaphragmatic pressure.
B. Administer prescribed intravenous analgesics for shoulder pain.
C. Position the patient in a prone position to stabilize the catheter.
D. Increase the fill volume on the next cycle by 200 mL.
Acute shoulder pain and shortness of breath during dialysate instillation are classic
indicators of diaphragmatic irritation caused by elevated intra-abdominal pressure or fluid
passing through a congenital diaphragmatic defect. Draining the fluid immediately relieves
the upward pressure on the diaphragm.
2. During a routine clinic visit, a patient performing automated peritoneal dialysis (APD)
exhibits cloudy peritoneal effluent drainage. The patient is currently asymptomatic with a
normal temperature and no abdominal tenderness. Which action should the nurse take
first?
A. Discontinue peritoneal dialysis permanently and transition the patient to hemodialysis.
B. Obtain a sample of the effluent for cell count, Gram stain, and culture sensitivity.
C. Reassure the patient that asymptomatic cloudy fluid is a normal variant of cycler use.
D. Administer empiric intravenous vancomycin without collecting diagnostic samples.
Cloudy effluent is the hallmark sign of peritonitis, even in the absence of severe systemic
symptoms. Diagnostic workup including cell count, differential, and cultures must be
performed promptly to identify the causative organism and initiate targeted therapy.
3. Which of the following anatomic structures serves as the primary semi-permeable
membrane utilized during peritoneal dialysis exchange procedures?
A. The parietal peritoneum lining the inner abdominal wall.
B. The visceral peritoneum covering internal abdominal organs.
,C. The peritoneal membrane consisting of capillaries and mesothelial cells.
D. The muscular layer of the anterior abdominal wall.
The peritoneal membrane, comprising a rich network of capillaries and a single layer of
mesothelial cells, acts as the natural semi-permeable filter allowing metabolic waste products
and excess water to cross via diffusion and osmosis.
4. A patient with end-stage renal disease is evaluating dialysis modalities. Which of the
following pre-existing medical conditions represents a relative or absolute contraindication
specifically for peritoneal dialysis?
A. Well-controlled essential hypertension.
B. Extensive prior abdominal surgeries resulting in severe peritoneal adhesions.
C. Early-stage type 2 diabetes mellitus managed with oral agents.
D. Stable mild chronic obstructive pulmonary disease.
Extensive abdominal adhesions can severely compromise the functional surface area of the
peritoneal membrane and impede proper dialysate flow and drainage, making peritoneal
dialysis technically unfeasible.
5. A patient on continuous cyclic peritoneal dialysis (CCPD) complains of poor dialysate
drainage, characterized by a slow, stuttering stream and a low total drained volume. What
is the most common mechanical cause of this phenomenon?
A. Catheter tip migration out of the pelvic gutter.
B. Fibrin strand accumulation obstructing the catheter lumen.
C. Constipation causing mechanical compression of the catheter.
D. Extrinsic kinking of the transfer set tubing.
Constipation is the single most frequent mechanical cause of inflow and outflow failure in
peritoneal dialysis. A full bowel shifts the catheter or exerts direct pressure, impeding fluid
movement.
6. When educating a newly trained patient on exit-site care, which cleansing agent is
generally discouraged due to its potential to degrade silicone and polyurethane catheter
materials?
A. Mild soap and warm water.
B. Hydrogen peroxide or alcohol-based solutions.
, C. Normal saline solution.
D. Chlorhexidine gluconate.
Harsh agents like hydrogen peroxide and isopropyl alcohol can dry out the tissue and degrade
the structural integrity of silicone or polyurethane peritoneal catheters, increasing the risk of
cracking and infection.
7. A patient presents with signs of dialysate leak around the catheter insertion site two
weeks after surgical placement. What is the recommended conservative management step
before considering surgical revision?
A. Temporarily pause peritoneal dialysis or switch to low-volume supine exchanges.
B. Suture the exit site closed tightly in an outpatient clinic setting.
C. Increase the dwell volume to tamponade the leakage tract.
D. Flush the catheter aggressively with heparinized saline.
Early dialysate leaks around the exit site are typically managed by resting the peritoneum,
switching to a lower volume, or temporarily transferring the patient to hemodialysis to allow
the tissue tract to heal.
8. Which peritoneal equilibration test (PET) category describes a patient whose dialysate-
to-plasma creatinine ratio equilibrates rapidly, indicating a high rate of solute transport?
A. Low transporter.
B. Low-average transporter.
C. High-average transporter.
D. High transporter.
High transporters rapidly transfer small solutes like creatinine and urea across the
membrane, but they lose ultrafiltration capacity quickly during long dwell times, making short
dwell times or CCPD more suitable.
9. A patient undergoing automated peritoneal dialysis experiences frequent "drain alarms"
during the night, particularly when lying on their side. What troubleshooting technique
should the nurse suggest?
A. Advise the patient to skip the final fill cycle of the prescription.
B. Implement measures to treat or prevent constipation and adjust sleeping position.
C. Clamp the catheter permanently and switch modalities.
