Correct Answer: A

Rationale: Implementing a regular toileting schedule is an appropriate nursing action for a client at risk for falls. This action can help prevent accidents related to rushing to the bathroom. Encouraging the client to wear athletic socks when ambulating (Choice B) is not safe as it can increase the risk of slipping and falling. Placing all four bed rails in the upright position (Choice C) can lead to entrapment or falls when the client tries to get out of bed. Requiring a family member to remain at the bedside (Choice D) may not always be feasible and does not directly address fall prevention strategies like the toileting schedule.

Correct Answer: D

Rationale: Correct! A calcium level of 8.0 mg/dL indicates hypocalcemia. Hypocalcemia can lead to increased neuromuscular excitability, manifesting as tingling of the extremities. Choices A, B, and C are incorrect findings associated with other electrolyte imbalances or conditions and are not typically related to hypocalcemia. Constipation is commonly seen in hypokalemia, absent deep-tendon reflexes are associated with hypermagnesemia, and nausea and vomiting are more indicative of hypercalcemia.

Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: C

Rationale: The correct answer is C: Serum potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Therefore, the nurse should monitor the client's serum potassium levels to prevent hyperkalemia, which can be a potential side effect of spironolactone. Monitoring total bilirubin levels (A) is not specifically required for clients taking spironolactone. Urine ketones (B) are not directly influenced by spironolactone use. Platelet count (D) is not typically monitored in clients taking spironolactone.

Correct Answer: C

Rationale: After a bronchoscopy, the nurse's priority is to check for a gag reflex. This action helps assess the client's ability to protect their airway after sedation. Maintaining airway patency is crucial post-procedure. Monitoring oxygen levels is important but ensuring airway protection takes precedence. Encouraging the client to eat and administering IV fluids are essential aspects of care but are not the immediate priority in this situation.
