In a 3-point gait pattern, what is the sequence of movement?
One crutch and the opposite leg move simultaneous, followed by the other crutch and leg
Advancing one crutch at a time, followed by each leg separately
Both crutches and the affected leg move forward, then the unaffected leg advances
Both crutches move forward, followed by a hop with both legs.
The Correct Answer is C
A. One crutch and the opposite leg move simultaneously, followed by the other crutch and leg: This describes a 4-point gait, where each crutch and leg move in sequence for maximum stability. It is not the correct sequence for a 3-point gait pattern.
B. Advancing one crutch at a time, followed by each leg separately: This is also consistent with a 4-point gait because it emphasizes alternating movement between crutches and legs, rather than moving both crutches together.
C. Both crutches and the affected leg move forward, then the unaffected leg advances: This is the correct 3-point gait pattern. It allows the client to bear weight on the unaffected leg while moving the crutches and injured leg together, maintaining balance and mobility.
D. Both crutches move forward, followed by a hop with both legs: This describes the swing-to or swing-through gait, often used by clients with paralysis or severe bilateral lower extremity weakness.

Correct Answer is B
Explanation
A. Sodium 140 mEq/L: This value is within the normal reference range (135–145 mEq/L). Sodium balance is important to monitor with many medications, but this finding does not pose a contraindication to initiating amphotericin B.
B. BUN 55 mg/dL: This value is significantly elevated above the normal range (10–20 mg/dL). Amphotericin B is nephrotoxic, and impaired renal function increases the risk of severe kidney injury. This abnormal result must be reported before administering the drug.
C. Glucose 120 mg/dL: Although slightly above fasting normal levels, this value is not dangerously high and does not impact the safe initiation of amphotericin B. Glucose is not a critical concern in relation to this antifungal medication.
D. Potassium 4.5 mEq/L: This value is within the normal range (3.5–5.0 mEq/L). While amphotericin B can cause hypokalemia, a normal potassium level at baseline does not require withholding the drug.
Correct Answer is A
Explanation
A. Iron: Epoetin alfa stimulates red blood cell production, but adequate iron stores are necessary for hemoglobin synthesis. Increasing dietary iron supports the effectiveness of epoetin alfa and helps correct anemia associated with chronic kidney disease.
B. Sodium: Clients with chronic kidney disease are typically advised to restrict sodium to control hypertension and fluid retention. Increasing sodium intake would worsen edema and cardiovascular strain rather than support therapy.
C. Protein: Although protein is important for tissue repair, clients with chronic kidney disease are usually placed on a restricted protein diet to reduce nitrogenous waste buildup. Increasing protein would not enhance epoetin alfa’s effectiveness.
D. Potassium: Potassium levels are closely monitored in chronic kidney disease, and most clients are placed on potassium restriction to prevent hyperkalemia. Increasing potassium intake could be dangerous and lead to life-threatening cardiac complications.
