here are the answers to the questions:

6. A patient with a fracture of the pelvis is at high risk for significant internal bleeding due to the rich vascular supply in the area. A sudden decrease in blood pressure (hypotension) is a critical sign of hypovolemic shock, indicating severe blood loss, and requires immediate intervention.

• D. sudden decrease in blood pressure

7. For a 64-year-old client undergoing a total hip replacement, a larger gauge IV catheter is preferred to allow for rapid fluid administration, blood transfusions, and administration of viscous medications if needed during surgery. An 18-gauge catheter is generally considered appropriate for surgical patients.

• A. 18

8. The parathyroid glands regulate calcium levels. Damage to or accidental removal of these glands during thyroid surgery can lead to hypocalcemia (low calcium). Symptoms of hypocalcemia include neuromuscular irritability, which manifests as tingling in the hands and feet (paresthesia) and potentially laryngeal stridor (a high-pitched breathing sound due to laryngeal muscle spasm).

• C. laryngeal stridor and tingling in the hands and feet

9. Kyphosis refers to the outward curvature of the thoracic spine. A normal kyphotic curve is anatomically described as concave anteriorly and convex posteriorly. The normal range for this curvature is typically between 20 and 40 degrees.

• B. concave anteriorly and convex posteriorly

10. A positive Trousseau's sign (carpal spasm induced by inflating a blood pressure cuff) is a classic clinical manifestation of hypocalcemia (low serum calcium levels).

• B. Hypocalcemia

11. A dislodged tracheostomy tube is an emergency as it compromises the patient's airway. The immediate intervention is to re-establish the airway. The nurse should insert a tube and give oxygen to maintain the patient's breathing.

• D. Insert a tube and give oxygen

12. Following a thyroidectomy, there is a risk of airway obstruction due to swelling or hematoma, and potential laryngeal nerve damage. Therefore, having a tracheotomy set at the bedside is a crucial immediate safety measure to manage potential airway emergencies upon the patient's return to the ward.

• D. place a tracheotomy set at the bed side
