Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

2. After a CT scan with intravenous contrast medium, a client returns to the room complaining of shortness of breath and itching. Which intervention should the nurse implement?

• A. Call respiratory therapy to administer a breathing treatment.
• B. Send for an emergency tracheostomy set.
• C. Prepare a dose of epinephrine.
• D. Review the client's complete list of allergies.

Correct answer: C

Rationale: Preparing a dose of epinephrine is the correct intervention in this situation as the client is displaying symptoms of an anaphylactic reaction to the contrast medium used during the CT scan. Epinephrine is the first-line treatment for anaphylaxis due to its ability to reverse the symptoms rapidly. Calling respiratory therapy for a breathing treatment (Choice A) may not address the underlying allergic reaction and delay appropriate treatment. Sending for an emergency tracheostomy set (Choice B) is not indicated as the client's symptoms suggest an allergic reaction rather than airway obstruction. Reviewing the client's complete list of allergies (Choice D) is important but would not provide immediate relief for the client's current symptoms; administering epinephrine takes precedence in this situation.

3. Based on this strip, what is the interpretation of this rhythm?

• A. Atrial fibrillation.
• B. Ventricular tachycardia.
• C. Normal sinus rhythm.
• D. Second-degree heart block.

Correct answer: C

Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.

4. Which is a priority nursing intervention for the cognitively impaired child?

• A. The family will provide good nutrition.
• B. The family will provide loving interactions.
• C. Stimulation will improve.
• D. There will be contact with peers.

Correct answer: B

Rationale: The correct answer is B because nursing interventions for cognitively impaired children prioritize promoting loving interactions with family. This support helps in creating a nurturing environment that contributes to the child's well-being and development. Choice A is not the priority as good nutrition, though important, may not address the immediate emotional and social needs of the child. Choice C is vague and does not specify how stimulation will be provided. Choice D, contact with peers, is also valuable but not as crucial as the primary relationships and interactions within the family unit for a cognitively impaired child.

5. The healthcare provider writes several prescriptions for a client diagnosed with hospital-acquired pneumonia (HAP) that include a combination of broad-spectrum antibiotics. Which intervention should the nurse implement first?

• A. Administer the first dose of antibiotics.
• B. Obtain a chest X-ray.
• C. Administer oxygen therapy.
• D. Collect blood specimens for culture prior to starting antibiotic therapy.

Correct answer: D

Rationale: Collecting blood specimens for culture prior to starting antibiotic therapy is the priority intervention in a client diagnosed with hospital-acquired pneumonia. This step is crucial to identify the causative organism responsible for the infection and ensure that the antibiotics prescribed are appropriate for effective treatment. Administering antibiotics before collecting cultures may interfere with the accuracy of culture results, potentially leading to inappropriate treatment. While administering the first dose of antibiotics is important, obtaining a chest X-ray and administering oxygen therapy are secondary interventions compared to identifying the causative organism through blood cultures.
