Nursing Elites

1. What are the clinical signs of hyperglycemia in a patient with diabetes mellitus, and how should a nurse respond?

• A. Monitoring blood glucose levels and administering insulin
• B. Polyuria, polydipsia, and polyphagia
• C. Fatigue, blurred vision, and fruity breath
• D. Educating the patient on blood glucose monitoring

Correct answer: B

Rationale: The correct signs of hyperglycemia in a patient with diabetes mellitus are polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger). These symptoms indicate high blood sugar levels. Therefore, the correct response for a nurse would be to recognize these signs, monitor blood glucose levels, and administer insulin to manage the hyperglycemia. Choice A is incorrect because it only addresses the response aspect without mentioning the signs. Choices C and D are incorrect as they do not reflect the classic clinical signs of hyperglycemia in diabetes mellitus.

2. A nurse is preparing to administer a blood transfusion. What is the most important action to ensure patient safety?

• A. Check the patient's vital signs every 15 minutes during the transfusion.
• B. Verify the patient's identity with two identifiers before starting the transfusion.
• C. Ensure the blood product is administered within 4 hours of removal from the blood bank.
• D. Ensure the patient has signed the informed consent form.

Correct answer: B

Rationale: The most important action to ensure patient safety when administering a blood transfusion is to verify the patient's identity with two identifiers before starting the transfusion. This step is crucial to prevent transfusion errors, such as giving the blood to the wrong patient. Checking vital signs, ensuring timely administration, and confirming informed consent are also important aspects of blood transfusion safety but verifying the patient's identity is the highest priority to prevent errors.

3. 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.

4. Which factor places a patient at the highest risk for infection?

• A. A healthy immune system
• B. Presence of chronic illness
• C. Being well-nourished
• D. Age over 65 years

Correct answer: B

Rationale: The presence of chronic illness is the factor that places a patient at the highest risk for infection. Chronic illness can compromise the immune system's ability to fight off infections effectively, making individuals more susceptible to getting sick. Option A, a healthy immune system, actually reduces the risk of infection. Option C, being well-nourished, can support overall health but does not directly correlate with infection risk. While age over 65 years is a risk factor for certain infections due to age-related immune system changes, chronic illness has a more significant impact on infection risk.

5. A client has a new prescription for guaifenesin. What information regarding the action of guaifenesin should the nurse include in the teaching?

• A. Decreases mucus production
• B. Reduces nasal congestion
• C. Increases cough production
• D. Reduces fever

Correct answer: C

Rationale: The correct answer is C: 'Increases cough production.' Guaifenesin is an expectorant that works by increasing cough production to help clear secretions from the airways. Option A is incorrect because guaifenesin does not decrease mucus production but rather helps to make the mucus easier to cough up. Option B is incorrect as guaifenesin does not reduce nasal congestion. Option D is incorrect because guaifenesin does not have any effect on reducing fever.
