Question 1 of 5
A client with chronic obstructive pulmonary disease (COPD) presents with severe dyspnea and hypoxemia. What is the appropriate indication for initiating oxygen therapy in this client?
Correct Answer: D
Rationale: Preventing complications of hypoxia (D) is the primary indication for oxygen therapy in COPD with severe dyspnea and hypoxemia, averting tissue damage and organ failure (target SpO2 88-92%). Saturation above 95% (A) risks CO2 retention in COPD. Correcting pathology (B) requires other treatments. Relieving dyspnea (C) is a benefit, not the goal. Hypoxia prevention aligns with GOLD guidelines, prioritizing survival and function over symptom relief alone.
Question 2 of 5
The nurse is caring for a client receiving oxygen therapy via a nasal cannula. Which action by the nurse is appropriate when providing oral care to the client?
Correct Answer: A
Rationale: Removing the nasal cannula during oral care (A) allows thorough hygiene without interference, briefly tolerable given short duration. Increasing flow (B) is unnecessary. Petroleum jelly (C) isn't for oral care. Mouth breathing (D) isn't needed if removed. Removal, per nursing practice, ensures effective care.
Question 3 of 5
Which of the following findings is associated with right-sided heart failure?
Correct Answer: B
Rationale: Nocturnal polyuria is linked to right-sided heart failure, where fluid shifts from edematous tissues to the bloodstream at night, increasing urine output as the heart struggles to pump against venous congestion. Shortness of breath and crackles typify left-sided failure, while daytime oliguria isn't specific. Nurses monitor this to assess heart function, guiding fluid management and diuretic use effectively.
Question 4 of 5
An 8-year-old admitted with an upper-respiratory infection has an order for O2 saturation via pulse oximeter. To ensure an accurate reading, the nurse should:
Correct Answer: D
Rationale: Placing the pulse oximeter probe on the finger ensures an accurate oxygen saturation reading in an 8-year-old, as peripheral sites like fingers provide reliable arterial pulsation data. The abdomen isn't suitable, recalibration isn't routine, and waiting 15 minutes delays care unnecessarily. Nurses use this technique for quick, precise monitoring, critical in respiratory infections to guide oxygen therapy.
Question 5 of 5
The LPN is preparing to administer an injection of vitamin K to the newborn. The nurse should administer the injection in the:
Correct Answer: B
Rationale: The vastus lateralis muscle is the preferred site for vitamin K injection in newborns, offering a large, safe muscle mass away from nerves and vessels, standard for intramuscular prophylaxis against hemorrhagic disease. Rectus femoris is smaller, deltoid underdeveloped, and dorsogluteal risky near sciatic nerve. Nurses use this site for efficacy and safety, teaching parents its purpose in clotting support.
