A home health nurse visits a client who has COPD and receives oxygen at 2 L/min via nasal cannula. The client reports difficulty breathing. Which of the following actions is the nurse's priority?

A. Increase the oxygen flow to 3 L/min.

B. Assess the client's respiratory status.

C. Call emergency services for the client.

D. Have the client cough and expectorate secretions.

Correct Answer: Assess the client's respiratory status.
Rationale: When a client with COPD on oxygen therapy reports difficulty breathing, the priority action for the nurse is to assess the client's respiratory status. This involves evaluating the client's oxygen saturation levels, respiratory rate, effort of breathing, lung sounds, and overall respiratory distress. By assessing the client's respiratory status, the nurse can determine the severity of the situation and make appropriate decisions regarding further interventions, such as adjusting oxygen flow rate, providing respiratory treatments, or seeking emergency assistance if necessary.

A client with diabetes is experiencing symptoms of hypoglycemia. What should the nurse administer first?

• A. 10 units of regular insulin subcutaneously
• B. 50 mL of 50% dextrose solution intravenously
• C. 1 mg of glucagon intramuscularly
• D. 15-20 grams of fast-acting carbohydrate orally

Correct Answer: D
Rationale: The correct first intervention for a client experiencing hypoglycemia is administering 15-20 grams of fast-acting carbohydrate orally. If the client is conscious and able to swallow, providing quick-acting carbohydrates helps raise blood glucose levels rapidly and effectively. This approach is preferred over other options like administering insulin, dextrose solution intravenously, or glucagon, which are not the initial interventions for hypoglycemia.

A healthcare provider is assessing a client immediately after the removal of the endotracheal tube. Which of the following findings should the provider report to the healthcare provider?

• A. Stridor
• B. Copious oral secretions
• C. Hoarseness
• D. Sore throat

Correct Answer: Stridor
Rationale: Stridor is a high-pitched, harsh respiratory sound that can indicate airway obstruction. It is a serious finding that requires immediate attention as it may lead to respiratory compromise. Copious oral secretions, hoarseness, and sore throat are common but expected findings after endotracheal tube removal and do not typically require urgent intervention.

A client is postoperative, and a nurse is developing a plan of care. Which of the following interventions should the nurse include in the plan to prevent pulmonary complications?

• A. Perform range-of-motion exercises
• B. Place suction equipment at the bedside
• C. Encourage the use of an incentive spirometer
• D. Administer an expectorant

Correct Answer: Encourage the use of an incentive spirometer
Rationale: Encouraging the use of an incentive spirometer is vital in preventing pulmonary complications postoperatively. The incentive spirometer helps the client perform deep breathing exercises, promoting lung expansion, and preventing atelectasis. Range-of-motion exercises help prevent musculoskeletal complications, while placing suction equipment at the bedside is important but not directly related to preventing pulmonary complications. Administering an expectorant may help with clearing secretions but is not as effective in preventing postoperative pulmonary complications as using an incentive spirometer.

A client has a pulmonary embolism & is started on oxygen. The student nurse asks why the client's oxygen saturation has not significantly improved. What response by the nurse is best?

• A. Breathing so rapidly interferes with oxygenation.
• B. Maybe the client has respiratory distress syndrome.
• C. The blood clot interferes with perfusion in the lungs.
• D. The client needs immediate intubation & mechanical ventilation.

Correct Answer: C
Rationale: A large blood clot in the lungs will significantly impair gas exchange & oxygenation. Unless the clot is dissolved, this process will continue unabated.
