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. A young adult client, admitted to the emergency department following a motor vehicle collision, is transfused with 4 units of PRBCs. The client’s pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all PRBCs have been transfused?

• A. 23%
• B. 25%
• C. 27%
• D. 29%

Correct answer: D

Rationale: One unit of PRBCs typically raises the hematocrit by 3%. Since the client received 4 units, the hematocrit is expected to increase by approximately 12% (4 units x 3% per unit). Therefore, the nurse should expect the client's hematocrit to be 29% after all PRBCs have been transfused. Choices A, B, and C are incorrect as they do not account for the cumulative effect of multiple PRBC units on the hematocrit level.

3. Ten hours following thrombolysis for an ST elevation myocardial infarction (STEMI), a client is receiving a lidocaine infusion for isolated runs of ventricular tachycardia. Which finding should the nurse document in the EMR as a therapeutic response to the lidocaine infusion?

• A. Stabilization of BP ranges
• B. Cessation of chest pain
• C. Reduced heart rate
• D. Decreased frequency of episodes of VT

Correct answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.

4. What is a priority action for the nurse when caring for a client with suspected meningitis?

• A. Isolate the client in a private room
• B. Administer intravenous antibiotics
• C. Obtain a throat culture
• D. Perform a chest x-ray

Correct answer: B

Rationale: Administering intravenous antibiotics is the priority when caring for a client with suspected meningitis. The prompt administration of antibiotics is crucial to treat bacterial meningitis and prevent potential complications. Isolating the client in a private room may be necessary to prevent the spread of infection, but antibiotic administration takes precedence. Obtaining a throat culture and performing a chest x-ray are important diagnostic measures, but they do not address the immediate need for antibiotic therapy in suspected bacterial meningitis.

5. An adult client is admitted with AIDS and oral candidiasis manifested by several painful mouth ulcers. The nurse delegates oral care to the unlicensed assistive personnel (UAP) and discusses how to assist the client. Which instruction should the nurse provide the UAP?

• A. Assist with personal care, but leave oral care for the nurse to complete.
• B. Provide a soft bristle brush for the client to use during oral care.
• C. Use alcohol-based mouthwash to clean the ulcers.
• D. Apply an antifungal cream to the mouth ulcers.

Correct answer: B

Rationale: The correct answer is B: 'Provide a soft bristle brush for the client to use during oral care.' Providing a soft bristle brush helps reduce trauma to the oral mucosa and assists in oral care. Choice A is incorrect because oral care can be safely delegated to UAPs. Choice C is wrong as alcohol-based mouthwash can further irritate the ulcers. Choice D is incorrect as applying an antifungal cream directly to the mouth ulcers is not the standard treatment for oral candidiasis.
