What precaution should a nurse take to minimize the risk of death when using potassium chloride to flush a lock or central venous catheter?

Correct Answer: A

Rationale: The correct answer is A because concentrated potassium chloride can cause cardiac arrest if injected rapidly.

Correct Answer: C

Rationale: Heavy lifting can increase intraocular pressure, exacerbating glaucoma.

Correct Answer: A

Rationale: Step 1: Increased respiratory rate from 18 to 44/min indicates potential respiratory distress, a serious complication post-fracture. Step 2: Rapid breathing can signify hypoxemia, pulmonary embolism, or infection, requiring immediate intervention. Step 3: Increased oral temperature and blood pressure within normal range are not as critical as respiratory distress. Step 4: A slight increase in heart rate is common after a fracture and not indicative of a serious complication.

Correct Answer: D

Rationale: The correct answer is D: Airway patency. Assessing airway patency is the priority in the immediate postoperative period following a laryngectomy to ensure the client's ability to breathe. If the airway is compromised, it can lead to life-threatening complications. Pain severity (A), wound drainage (B), and tissue integrity (C) are important assessments but are secondary to ensuring the client's airway is clear and functioning properly. Prioritizing airway patency allows for prompt intervention if any issues arise, ensuring the client's safety and optimal recovery.

Correct Answer: C

Rationale: Bisphosphonates require specific administration guidelines to enhance absorption.
