The nurse presents information to a group of nursing students about cultural and ethnic health disparities related to hypertension. Which information would the nurse include about the comparison of Mexican Americans to White and Black populations?
- A. Mexican Americans have higher rates of good blood pressure control.
- B. Mexican Americans are more likely to receive treatment for hypertension.
- C. Mexican Americans have the highest prevalence of hypertension in the world.
- D. Mexican Americans have lower levels of awareness of hypertension and its treatment.

The nurse provides discharge teaching to a patient with venous leg ulcers. Which statement made by the patient indicates the need for further education?
- A. I will take a walk daily.
- B. I will try to lose at least 20 pounds.
- C. I will put on my stockings after I get out of bed each day.
- D. I will not wear knee-high socks that are tight around my calf.
Correct Answer: D
Rationale: Not wearing tight knee-high socks is correct, as tight clothing can impede circulation; the statement suggests misunderstanding, indicating a need for further education.
Which strategy is most important for a nurse to include when planning care for a patient who has neutropenia?
- A. Restricting all visitors.
- B. Placing the patient in a private room.
- C. Advising the patient to use only an electric shaver.
- D. Wearing a gown and gloves when in direct contact with the patient.
Correct Answer: B
Rationale: Placing the patient in a private room is crucial for a neutropenic patient to minimize exposure to pathogens, reducing infection risk due to their compromised immune system.
Which arterial blood gas (ABG) data corresponds with a patient's clinical manifestations of respiratory alkalosis?
- A. pH = 7.46, PaCO2 = 44 mm Hg, PaO2 = 95 mm Hg, and HCO3 = 36 mEq/L.
- B. pH = 7.27, PaCO2 = 70 mm Hg, PaO2 = 80 mm Hg, and HCO3 = 26 mEq/L.
- C. pH = 7.30, PaCO2 = 35 mm Hg, PaO2 = 70 mm Hg, and HCO3 = 20 mEq/L.
- D. pH = 7.52, PaCO2 = 24 mm Hg, PaO2 = 85 mm Hg, and HCO3 = 24 mEq/L.
Correct Answer: D
Rationale: Respiratory alkalosis is characterized by a high pH (>7.45) and a low PaCO2 (<35 mm Hg). The data in option D (pH = 7.52, PaCO2 = 24 mm Hg) indicates respiratory alkalosis.
The arterial blood gas (ABG) results for a patient who overdosed on barbiturates are pH = 7.32, PaCO2 = 52, and HCO3 = 23. Which interpretation would the nurse rely on when planning the patient's care?
- A. Metabolic acidosis.
- B. Metabolic alkalosis.
- C. Respiratory acidosis.
- D. Respiratory alkalosis.
Correct Answer: C
Rationale: The given ABG results indicate a low pH (acidosis), an elevated PaCO2 (respiratory component), and a normal HCO3 (metabolic component). The low pH and increased PaCO2 suggest respiratory acidosis.
