Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. A client with heart failure has a new prescription for furosemide. Which of the following statements should the nurse make?

• A. Taking furosemide can cause your potassium levels to be high
• B. Eat foods that are high in sodium
• C. Rise slowly when getting out of bed
• D. Taking furosemide can cause you to be overhydrated

Correct answer: C

Rationale: Educating the client on the importance of rising slowly when getting out of bed is crucial due to the risk of orthostatic hypotension associated with furosemide use. This precaution helps prevent dizziness and falls. Options A and D are incorrect as furosemide commonly causes hypokalemia and dehydration, respectively, rather than high potassium levels or overhydration. Option B is inaccurate as clients on furosemide need to reduce sodium intake to manage fluid retention.

3. A client with vision loss is under the care of a nurse. Which of the following actions should the nurse AVOID?

• A. Keep objects in the client's room in the same place
• B. Ensure there is high-wattage lighting in the client's room
• C. Approach the client from the side
• D. Allow extra time for the client to perform tasks

Correct answer: C

Rationale: Approaching a client with vision loss from the side can startle them and may lead to accidents or discomfort. It is important to approach them from the front so they are aware of your presence. Keeping objects in the same place aids in familiarity and reduces the risk of falls. High-wattage lighting enhances visibility for the client. Allowing extra time for tasks accommodates the client's potential slower pace and ensures they can perform tasks safely.

4. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

5. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.
