A client is to have hemodialysis. What must the nurse do before this treatment?

Administer scheduled medications

Explain that dialysis occurs via the peritoneum

Weigh the client to determine a baseline for comparison

Obtain a serum creatinine to determine kidney function

Answer and Explanation

The Correct Answer is C

A. Administer scheduled medications: Some medications (e.g., antihypertensives, water-soluble vitamins, and antibiotics) should be held before dialysis to prevent removal during treatment.

B. Explain that dialysis occurs via the peritoneum: This describes peritoneal dialysis, not hemodialysis.

C. Weigh the client to determine a baseline for comparison: Pre-dialysis weight is crucial to determine fluid removal needs during dialysis. Weight differences before and after dialysis indicate fluid loss or retention.

D. Obtain a serum creatinine to determine kidney function: Serum creatinine levels are monitored regularly but are not a required step before every dialysis session.

Correct Answer is B

Explanation

A. ST depression: ST depression is associated with hypokalemia or ischemia.

B. Tall peaked T waves: Hyperkalemia (K+ > 5.0 mEq/L) causes tall, peaked T waves due to abnormal repolarization. Severe hyperkalemia (>6.5 mEq/L) can lead to cardiac arrest.

C. Prolonged ST segment: Not a characteristic of hyperkalemia.

D. Prominent U wave: A U wave is seen in hypokalemia, not hyperkalemia.

A. 0.45% sodium chloride B. 0.9% sodium chloride C. Lactated Ringers D. Albumin

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"B"},"D":{"answers":"C"}}

Explanation

Solutions	Hypotonic	Isotonic	Hypertonic
0.45% sodium chloride	✅
0.9% sodium chloride		✅
Lactated Ringers		✅
Albumin			✅

0.45% Sodium Chloride (Hypotonic): Has lower osmolarity than blood, causing fluid to shift into cells, making them swell. Used for dehydration and intracellular rehydration.

0.9% Sodium Chloride (Isotonic): Has the same osmolarity as blood, so it stays in the intravascular space. Used for fluid resuscitation (hypovolemia, dehydration, shock).

Lactated Ringers (Isotonic): Contains electrolytes (Na+, K+, Ca2+, lactate), making it ideal for burns, surgery, and trauma patients. Maintains intravascular volume without fluid shifts.

Albumin (Hypertonic): Large protein that pulls fluid into the intravascular space (colloid osmotic pressure). Used for hypovolemia, burns, or severe hypoalbuminemia.
