Nursing Elites

1. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

2. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

3. A client with thrombocytopenia is receiving care from a nurse. Which of the following actions should the nurse include?

• A. Encourage the client to floss daily.
• B. Remove fresh flowers from the client's room.
• C. Provide the client with a stool softener.
• D. Avoid serving the client raw vegetables.

Correct answer: C

Rationale: In a client with thrombocytopenia, the platelet count is low, leading to a risk of bleeding. Providing a stool softener is essential to prevent constipation and straining during bowel movements, which can reduce the risk of bleeding episodes. Encouraging the client to floss daily (Choice A) is a good oral hygiene practice but is not directly related to thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is related to infection control but does not address the specific risk of bleeding in thrombocytopenia. Avoiding serving the client raw vegetables (Choice D) is important in clients with neutropenia to prevent infections, not in thrombocytopenia.

4. What is the best intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Administer IV fluids
• D. Reposition the patient

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation. Oxygen therapy is the initial and priority intervention to ensure an adequate oxygen supply to the body tissues. Administering bronchodilators (Choice B) may be appropriate for specific respiratory conditions like asthma or COPD but is not the first-line intervention in all cases of respiratory distress. Administering IV fluids (Choice C) is not a standard intervention for respiratory distress unless there is an underlying cause like dehydration. Repositioning the patient (Choice D) can aid in optimizing ventilation but is not the primary intervention for respiratory distress.

5. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be elevated?

• A. Serum albumin.
• B. Ammonia.
• C. Bilirubin.
• D. Prothrombin time.

Correct answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.
