Adequate protein intake supports cellular regeneration and helps prevent complications like skin breakdown.

Question 116: A patient with lymphoma develops rapid onset of elevated serum potassium, elevated phosphate, elevated uric acid, and decreased calcium. The nurse recognizes this as:

Hyperparathyroidism
Tumor lysis syndrome (TLS) (Correct answer)
Addisonian crisis
Septic shock

Correct answer: Tumor lysis syndrome (TLS)

The metabolic tetrad of hyperkalemia, hyperphosphatemia, hyperuricemia, and hypocalcemia is diagnostic of tumor lysis syndrome.

Question 117: What is the nadir period in chemotherapy treatment?

The point at which blood cell counts reach their lowest level after treatment (Correct answer)
The peak drug concentration in the blood
The recovery phase after completing all treatments
The first day of a chemotherapy cycle

Correct answer: The point at which blood cell counts reach their lowest level after treatment

The nadir is the point of lowest blood cell counts (particularly neutrophils and platelets) following chemotherapy, typically occurring 7-14 days after treatment, when patients are most vulnerable to infection and bleeding.

Question 118: Which of the following is a common complication of ostomies?

Tooth decay
Peristomal skin irritation (Correct answer)
Joint dislocation
Nasal congestion

Correct answer: Peristomal skin irritation

Peristomal skin irritation is a very common complication for ostomy patients, occurring when the skin around the stoma becomes inflamed or damaged. This can be due to exposure to stoma output, adhesive trauma, or an improperly fitting appliance. COCNs are trained to prevent and manage this issue through proper skin care and appliance selection.

Question 119: What is the recommended action if the stoma retracts below skin level?

Apply powder only
Discontinue pouch use
Use a flat barrier
Switch to a convex barrier (Correct answer)

Correct answer: Switch to a convex barrier

If a stoma retracts below skin level, a convex skin barrier is recommended. Convex barriers have a dome shape that gently presses into the peristomal skin, pushing the stoma outward and creating a better seal. This helps to prevent effluent from seeping under the barrier and irritating the skin, which is a common problem with retracted stomas.

Question 120: What is the significance of a convex barrier in ostomy care?

Supports seal for retracted stomas (Correct answer)
Improves digestion
Reduces body odor
Cleans the stoma

Correct answer: Supports seal for retracted stomas

A convex barrier is designed with a dome shape that gently presses into the peristomal skin, helping to create a secure seal for stomas that are flush, retracted, or located in a skin fold. This convexity helps to evert the stoma and prevent leakage, which is crucial for maintaining skin integrity and appliance adherence. It provides gentle pressure to ensure output drains into the pouch.
