A patient who smokes reports chest pain while at rest.
Which condition would the nurse suspect the patient is experiencing?

Silent ischemia.

Angina decubitus.

Prinzmetal angina.

Chronic stable angina.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Silent ischemia refers to a lack of oxygen to the heart that doesn't cause symptoms like chest pain. It is often diagnosed during an electrocardiogram (ECG) done for other reasons. The patient in this scenario is experiencing chest pain, so silent ischemia is not the correct choice.

Choice B rationale:

Angina decubitus refers to chest pain that occurs while lying down and is relieved by standing or sitting. The patient in this scenario is experiencing chest pain at rest, which is not characteristic of angina decubitus.

Choice D rationale:

Chronic stable angina is chest pain or discomfort that typically occurs with activity or stress and is relieved by rest or nitroglycerin. The patient in this scenario is experiencing chest pain at rest, which is not characteristic of chronic stable angina.

Correct Answer is C

Explanation

Choice A rationale:

While magnesium is indeed the most abundant intracellular cation in the body, this fact alone does not explain why the nurse would assess the patient's magnesium level.

Choice B rationale:

Magnesium imbalance can cause issues in the extracellular fluid compartment, but this choice does not explain why the nurse would specifically assess the patient's magnesium level.

Choice D rationale:

While hypotension can be a symptom of severe magnesium deficiency, this choice does not provide a rationale for assessing the patient's magnesium level. In this case, choice C is correct because magnesium plays a crucial role in neuromuscular excitability and contractility. Abnormal magnesium levels can lead to neuromuscular symptoms such as muscle weakness, tremors, and spasms. Additionally, magnesium is involved in cardiac muscle function, and low magnesium levels can lead to arrhythmias and other cardiac issues. Therefore, assessing the patient's magnesium level is essential in understanding their neuromuscular and cardiac health.

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 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.
