Nursing Elites

1. What is the priority intervention for a patient with a suspected myocardial infarction (MI)?

• A. Administering oxygen.
• B. Administering nitroglycerin.
• C. Administering aspirin.
• D. Administering morphine.

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with a suspected myocardial infarction to improve oxygenation. Oxygen helps ensure an adequate oxygen supply to the heart muscle, reducing the workload on the heart. Nitroglycerin and aspirin are important interventions in the treatment of MI; however, oxygen administration takes precedence to ensure adequate oxygenation. Morphine may be considered for pain relief, but it is not the initial priority in the treatment of a suspected MI.

2. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?

• A. Carbon dioxide is converted in the kidneys for elimination.
• B. Blood oxygen levels are stimulating the respiratory rate.
• C. Hyperventilation is eliminating carbon dioxide rapidly.
• D. High levels of carbon dioxide have accumulated in the blood.

Correct answer: D

Rationale: The correct answer is D. High levels of carbon dioxide in the blood are indicative of respiratory acidosis, often due to inadequate ventilation. In respiratory acidosis, there is retention of carbon dioxide (hypercapnia) leading to an increase in carbonic acid levels in the blood, resulting in an acidic pH. Option A is incorrect because carbon dioxide elimination primarily occurs through the lungs, not the kidneys. Option B is incorrect because blood oxygen levels primarily affect the respiratory rate to regulate oxygen levels, not carbon dioxide levels. Option C is incorrect because hyperventilation would lead to a decrease, not an increase, in carbon dioxide levels.

3. A nurse reviews a client’s urinalysis report. Which finding does the nurse recognize as abnormal?

• A. pH of 6.0
• B. An absence of protein
• C. The presence of ketones
• D. Specific gravity of 1.018

Correct answer: C

Rationale: The correct answer is C. The presence of ketones in the urine is abnormal. Ketones in the urine may indicate a state of ketosis, which is commonly seen in uncontrolled diabetes, fasting, or a low-carbohydrate diet. A normal pH range of urine is 4.5 to 7.8, making a pH of 6.0 within the normal range. An absence of protein is a normal finding in urine, as proteinuria (presence of protein) is abnormal. A specific gravity of 1.018 falls within the normal range of 1.016 to 1.022. Therefore, the presence of ketones is the abnormal finding in this scenario.

4. The nurse is taking the vital signs of a client after hemodialysis. Blood pressure is 110/58 mm Hg, pulse 66 beats/min, and temperature is 99.8°F (37.6°C). What is the most appropriate action by the nurse?

• A. Administer fluids to increase blood pressure.
• B. Check the white blood cell count.
• C. Monitor the client’s temperature.
• D. Connect the client to an electrocardiographic (ECG) monitor.

Correct answer: C

Rationale: After hemodialysis, it is crucial to monitor the client's temperature because the dialysate is warmed to increase diffusion and prevent hypothermia. The client's temperature might reflect the temperature of the dialysate. There is no need to administer fluids to increase blood pressure as the vital signs are within normal limits. Checking the white blood cell count or connecting the client to an ECG monitor is not necessary based on the information provided.

5. A client with a history of lung disease is at risk for respiratory acidosis. For which of the following signs and symptoms does the nurse assess this client?

• A. Disorientation and dyspnea
• B. Drowsiness, headache, and tachypnea
• C. Tachypnea, dizziness, and paresthesias
• D. Dysrhythmias and decreased respiratory rate and depth

Correct answer: A

Rationale: The correct answer is A: Disorientation and dyspnea. In respiratory acidosis, the retention of carbon dioxide leads to an increase in carbonic acid, causing the pH of the blood to decrease. This can result in symptoms such as dyspnea (difficulty breathing) due to hypoxia and disorientation due to the effects of hypercapnia (elevated carbon dioxide levels) on the brain. Choice B is incorrect because while drowsiness and tachypnea can be present in respiratory acidosis, headache is not a common symptom. Choice C is incorrect because dizziness and paresthesias are not typical symptoms of respiratory acidosis. Choice D is incorrect because dysrhythmias and a decreased respiratory rate and depth are more commonly associated with respiratory alkalosis, not respiratory acidosis.
