Nursing Elites

1. A client with pneumonia is receiving oxygen therapy. Which of the following oxygen delivery devices should be used to deliver a precise oxygen concentration?

• A. Nasal cannula
• B. Simple face mask
• C. Venturi mask
• D. Non-rebreather mask

Correct answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.

2. A patient with diabetes is admitted with high blood sugar levels. What is the nurse's priority intervention?

• A. Administer insulin as prescribed.
• B. Encourage the patient to exercise regularly.
• C. Encourage the patient to drink water.
• D. Provide the patient with a low-sugar diet.

Correct answer: A

Rationale: Administering insulin is the priority intervention for a patient admitted with high blood sugar levels because it helps lower the blood sugar levels effectively and rapidly. Insulin is a crucial medication for managing hyperglycemia in diabetes. Encouraging exercise (choice B) can be beneficial in the long term for managing blood sugar levels but is not the most immediate priority. While staying hydrated (choice C) is important, it is not the priority intervention when dealing with high blood sugar levels. Providing a low-sugar diet (choice D) is essential for long-term diabetes management but is not the immediate action needed to address high blood sugar levels in an admitted patient.

3. A nurse is caring for a client who has heart failure and is prescribed furosemide. Which of the following outcomes indicates that the medication is effective?

• A. Improvement in visual acuity
• B. Decreased respiratory rate
• C. Weight loss of 1.36 kg (3 lb) in 24 hours
• D. Increased urinary output

Correct answer: D

Rationale: The correct answer is D. Increased urinary output is the desired outcome when administering furosemide to a client with heart failure. Furosemide is a diuretic that promotes the excretion of excess fluids from the body, which helps in reducing fluid overload, a common symptom of heart failure. Choices A, B, and C are not directly related to the action of furosemide in treating heart failure. Visual acuity improvement, decreased respiratory rate, and rapid weight loss are not typical indicators of furosemide effectiveness in managing heart failure.

4. A nurse is caring for a newborn in the nursery following a circumcision. The newborn's grandparent, who does not have an identification bracelet, requests to take the newborn to his parents' room. Which of the following actions should the nurse take?

• A. Check the newborn's identification bracelet against the chart
• B. Obtain permission from the newborn's parents
• C. Respectfully deny the grandparent's request
• D. Review the newborn's footprints record

Correct answer: C

Rationale: In this scenario, where the grandparent lacks proper identification, the nurse should respectfully deny the request to take the newborn. It is crucial to prioritize the newborn's safety and security by following hospital policies and procedures. Checking the newborn's identification bracelet against the chart (Choice A) may not be sufficient to address the situation at hand, as the grandparent's lack of identification is the primary concern. While obtaining permission from the newborn's parents (Choice B) is important, the lack of proper identification from the grandparent takes precedence. Reviewing the newborn's footprints record (Choice D) is not necessary in this situation, as the immediate concern is ensuring proper identification and security before allowing the newborn to leave the nursery.

5. A nurse is assessing a postoperative patient for signs of infection. Which finding is most concerning?

• A. Mild redness at the incision site.
• B. Increased drainage from the surgical site.
• C. Fever of 101°F.
• D. Normal white blood cell count.

Correct answer: C

Rationale: A fever of 101°F is the most concerning finding when assessing a postoperative patient for signs of infection. Fever can indicate an inflammatory response to an infection, and in a postoperative patient, it can signal a surgical site infection or a systemic infection. Prompt attention is necessary to prevent complications such as sepsis. Mild redness at the incision site and increased drainage can be expected in the early postoperative period due to the normal healing process. A normal white blood cell count does not rule out infection as it can be influenced by various factors, and some infections may not initially cause a rise in white blood cells.
