Question 1 of 5
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?
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.
Question 2 of 5
The nurse is reviewing blood pressure readings for a group of clients on a medical unit. Which client is at the highest risk for complications related to hypertension?
Correct Answer: D
Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.
Question 3 of 5
The nurse is teaching a client about coronary artery disease (CAD) preventive health. Which behavior stated by the client indicates a need for additional information and teaching?
Correct Answer: C
Rationale: The correct answer is C. Decreasing the number of cigarettes smoked per day is not sufficient for CAD prevention. Smoking cessation is crucial in reducing the risk of CAD. While increasing physical activity, eating a low-fat diet, and monitoring blood pressure regularly are all positive behaviors for CAD prevention, quitting smoking should be emphasized due to its significant impact on cardiovascular health.
Question 4 of 5
The nurse is triaging clients who have been injured during a tornado. Which client requires immediate action?
Correct Answer: C
Rationale: The middle-aged female with a broken humerus who is unable to follow commands and is crying requires immediate action. These symptoms indicate a possible head injury or severe emotional distress that need urgent attention. Choice A is not as urgent since a minor laceration can be addressed after more critical cases. Choice B, although having a dislocated shoulder, is stable, as the client is calm. Choice D presents with minor injuries that can wait while more critical cases are addressed.
Question 5 of 5
Based on this strip, what is the interpretation of this rhythm?
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.
