Which information would the nurse include when discussing pain due to chronic stable angina with the patient?

A.

Occurs with both activity and rest.

B.

Generally lasts 10-15 minutes or more.

C.

Does not subside when the precipitating factor is resolved.

D.

Occurs intermittently over a period of time in a similar pattern.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

Chronic stable angina typically occurs with activity and is relieved with rest or nitroglycerin. Therefore, this statement is incorrect for chronic stable angina.

Choice B rationale:

Chronic stable angina usually lasts for a short duration, usually around 5 minutes, and is relieved with rest or nitroglycerin. Prolonged pain lasting 10-15 minutes or more could indicate an unstable angina or myocardial infarction. This choice is incorrect for chronic stable angina.

Choice C rationale:

Pain due to chronic stable angina subsides when the precipitating factor, such as physical exertion, is resolved or with medication like nitroglycerin. Therefore, this statement is incorrect for chronic stable angina.

Choice D rationale:

Chronic stable angina follows a predictable pattern, occurring intermittently over a period of time, and is usually triggered by physical exertion or emotional stress. This option correctly describes the characteristic pattern of chronic stable angina.

Correct Answer is B

Explanation

Choice A rationale:

Methotrexate is a medication used for cancer and autoimmune diseases. It does not chelate iron and is not used to treat iron overload conditions like hemochromatosis.

Choice B rationale:

Deferoxamine is an iron chelating agent used to treat iron overload conditions like hemochromatosis. It binds to excess iron and promotes its excretion from the body, preventing complications such as organ damage.

Choice C rationale:

Ferrous gluconate is an iron supplement used to treat iron deficiency anemia. It would not be appropriate for a patient with hemochromatosis, a condition characterized by iron overload.

Choice D rationale:

Iron dextran complex is another form of intravenous iron used to treat iron deficiency anemia. It is not indicated for treating iron overload conditions like hemochromatosis.

Correct Answer is D

Explanation

The correct answer is choice d. pH = 7.52, PaCO2 = 24 mm Hg, PaO2 = 85 mm Hg, and HCO3 = 24 mEq/L.

Rationales:

Choice A rationale:

  • pH = 7.46: This value is slightly alkalotic.
  • PaCO2 = 44 mm Hg: This is within the normal range (35-45 mm Hg), indicating that the respiratory system is not contributing to alkalosis.
  • PaO2 = 95 mm Hg: This is a normal oxygen level.
  • HCO3 = 36 mEq/L: This is elevated, indicating metabolic alkalosis rather than respiratory alkalosis.

Choice B rationale:

  • pH = 7.27: This value is acidic, indicating acidosis.
  • PaCO2 = 70 mm Hg: This is elevated, indicating respiratory acidosis.
  • PaO2 = 80 mm Hg: This is slightly low, indicating mild hypoxemia.
  • HCO3 = 26 mEq/L: This is within the normal range, indicating no metabolic compensation.

Choice C rationale:

  • pH = 7.30: This value is acidic, indicating acidosis.
  • PaCO2 = 35 mm Hg: This is within the normal range, indicating that the respiratory system is not contributing to acidosis.
  • PaO2 = 70 mm Hg: This is low, indicating hypoxemia.
  • HCO3 = 20 mEq/L: This is low, indicating metabolic acidosis.

Choice D rationale:

  • pH = 7.52: This value is alkalotic.
  • PaCO2 = 24 mm Hg: This is low, indicating respiratory alkalosis.
  • PaO2 = 85 mm Hg: This is a normal oxygen level.
  • HCO3 = 24 mEq/L: This is within the normal range, indicating no metabolic compensation.

Choice D corresponds with respiratory alkalosis because the pH is alkalotic, and the PaCO2 is low, indicating that the respiratory system is causing the alkalosis. The HCO3 is within the normal range, showing no metabolic compensation.
