Which of the following best describes the 4-point gait pattern?

Advancing one crutch and the opposite leg simultaneously.

Moving both crutches forward followed by moving both legs together.

Advancing both crutches then hopping forward on the unaffected leg

Advancing each crutch separately followed by the opposite leg

Answer and Explanation

The Correct Answer is D

A. Advancing one crutch and the opposite leg simultaneously: This describes the two-point gait pattern, which allows partial weight-bearing on both legs and crutches. It does not reflect the sequence used in the four-point gait.

B. Moving both crutches forward followed by moving both legs together: This sequence corresponds to the swing-to or swing-through gait patterns, not the four-point gait. It involves moving both legs together rather than alternating steps.

C. Advancing both crutches then hopping forward on the unaffected leg: This describes the three-point gait for non-weight-bearing on one leg, which requires hopping on the unaffected leg after moving both crutches, unlike the four-point gait.

D. Advancing each crutch separately followed by the opposite leg: The four-point gait involves moving one crutch, then the opposite leg, then the other crutch, followed by the remaining leg. This provides maximum stability and is suitable for clients who can bear weight on both legs but need support.

Correct Answer is B

Explanation

A. Hold the prescribed dose and notify the provider of the serum potassium level: Holding the dose would be inappropriate because the client’s potassium level is low. Potassium supplementation is indicated to correct the hypokalemia and prevent complications.

B. Give the ordered KCL as prescribed: A potassium level of 3.2 mEq/L indicates mild hypokalemia. Administering the prescribed potassium chloride helps restore normal serum levels and supports cardiac and neuromuscular function, making this the appropriate action.

C. Omit the KCL dose and document that it was not given: Omitting the dose would leave the hypokalemia untreated and put the client at risk for worsening muscle weakness, cardiac arrhythmias, and potential respiratory compromise. Documentation alone does not address the clinical need.

D. Call the lab to verify the client’s results: Verification is not necessary when the value is consistent with the client’s condition and treatment plan. The result of 3.2 mEq/L clearly indicates hypokalemia, and prompt supplementation is the correct intervention.

Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"A"}

Explanation

Rationale for correct choices:

Deep vein thrombosis: The client’s limited mobility, recent hip fracture, and unilateral calf swelling and warmth significantly increase the risk for DVT. Immobility reduces venous return, promoting clot formation in the lower extremities, making early assessment and preventive measures critical.
Pulmonary embolism: A DVT can dislodge and travel to the lungs, causing a potentially life-threatening pulmonary embolism. Monitoring for signs such as sudden shortness of breath, chest pain, or hypoxia is essential to prevent serious complications.

Rationale for incorrect choices:

Diarrhea: There is no evidence of gastrointestinal upset, increased bowel movements, or infection that would place the client at risk for diarrhea.
Hypertension: The client’s vitals do not indicate elevated blood pressure, and there are no factors in the scenario suggesting risk for acute hypertension.
Hypocalcemia: The client’s lab results do not indicate low calcium levels, and there are no signs or symptoms suggestive of hypocalcemia, making this an unlikely risk.
