A nurse is reviewing the laboratory results of a client who was hyperventilating during a panic attack.
Which of the following arterial blood gas values should the nurse expect?
A. pH 7.50 and HCO3 31 mm Hg.
A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.
B. pH 7.30 and HCO3 19 mm Hg.
A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.
C. pH 7.47 and PaCO2 31 mm Hg.
A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.
D. pH 7.32 and PaCO2 50 mm Hg.
A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.

Full Explanation
The correct answer is: C.
Choice A reason: A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.
Choice B reason: A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.
Choice C reason: A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.
Choice D reason: A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.

A nurse reviewing the laboratory of a client who had a total thyroidectomy discovers that his calcium level is 7 mg/dL. Which of the following client findings should the nurse expect?
A. Hypertension.
Hypertension is not typically associated with low calcium levels. Hypertension is more commonly linked to issues with blood pressure regulation and not calcium levels.
B. Diaphoresis.
Diaphoresis (excessive sweating) is not a direct symptom of low calcium levels. Low calcium can lead to muscle cramps and tetany, but not sweating.
C. Muscle tetany.
Muscle tetany is a common manifestation of low calcium levels (hypocalcemia). It results from increased neuromuscular excitability, causing muscle spasms and contractions. A calcium level of 7 mg/dL is below the normal range, and this client is at risk for muscle tetany.
D. Increased thirst.
Increased thirst is not a typical symptom of low calcium levels. Symptoms of hypocalcemia are primarily related to neuromuscular and cardiovascular changes, such as muscle tetany and cardiac arrhythmias.
Full Explanation
Choice A rationale:
Hypertension is not typically associated with low calcium levels. Hypertension is more commonly linked to issues with blood pressure regulation and not calcium levels.
Choice B rationale:
Diaphoresis (excessive sweating) is not a direct symptom of low calcium levels. Low calcium can lead to muscle cramps and tetany, but not sweating.
Choice C rationale:
Muscle tetany is a common manifestation of low calcium levels (hypocalcemia). It results from increased neuromuscular excitability, causing muscle spasms and contractions. A calcium level of 7 mg/dL is below the normal range, and this client is at risk for muscle tetany.
Choice D rationale:
Increased thirst is not a typical symptom of low calcium levels. Symptoms of hypocalcemia are primarily related to neuromuscular and cardiovascular changes, such as muscle tetany and cardiac arrhythmias.
A nurse is reinforcing teaching about self-management strategies with a client who has emphysema.
Which of the following client statements indicates that the client understands the instructions?
A. "I will drink about 34 ounces of fluid every day.”.
“I will drink about 34 ounces of fluid every day.” While staying hydrated is important for overall health, this statement does not specifically address a key self-management strategy for emphysema. Adequate fluid intake can help thin mucus, making it easier to expel, but it is not the most critical aspect of managing emphysema.
B. "I will inhale slowly through pursed lips to help me breathe better.”.
“I will inhale slowly through pursed lips to help me breathe better.” This statement is incorrect because the correct technique is to exhale through pursed lips, not inhale. Pursed-lip breathing helps to keep the airways open longer, reduce shortness of breath, and improve the exchange of oxygen and carbon dioxide.
C. "I will follow a diet high in calories and protein.”.
“I will follow a diet high in calories and protein.” This is the correct answer. Emphysema can increase the body’s energy expenditure due to the effort required for breathing. A diet high in calories and protein helps maintain muscle mass and provides the necessary energy to support respiratory function.
D. "I will lie on my stomach to practice abdominal breathing every day.”. .
“I will lie on my stomach to practice abdominal breathing every day.” This statement is not recommended for emphysema management. While abdominal or diaphragmatic breathing can be beneficial, lying on the stomach is not a typical position for practicing this technique. It is usually done while sitting or lying on the back.
Full Explanation
The correct answer is choice C: “I will follow a diet high in calories and protein.”
Here are the rationales for each choice:
Choice A rationale: “I will drink about 34 ounces of fluid every day.” While staying hydrated is important for overall health, this statement does not specifically address a key self-management strategy for emphysema.

While abdominal or diaphragmatic breathing can be beneficial, lying on the stomach is not a typical position for practicing this technique. It is usually done while sitting or lying on the back.
A nurse is collecting data from a client who has heart failure, prior to the administration of furosemide.
For which of the following findings should the nurse withhold the medication?
A. Oxygen saturation of 95%.
Oxygen saturation of 95% The normal oxygen saturation level is between 95% and 100%. An oxygen saturation of 95% is within the normal range, so the nurse would not need to withhold furosemide for this reason.
B. Serum sodium level of 140 mEq/L.
Serum sodium level of 140 mEq/L The normal serum sodium levels range from 135 to 145 mEq/L. A serum sodium level of 140 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.
C. Blood pressure of 80/40 mm Hg.
Blood pressure of 80/40 mm Hg Furosemide is a potent diuretic that can lead to a significant depletion of electrolytes, which may lead to side effects such as muscle cramps and an irregular heartbeat. Low blood pressure (hypotension) is a potential side effect of furosemide. Normal blood pressure for adults is typically around 120/80 mm Hg. A blood pressure reading of 80/40 mm Hg is considerably lower than the normal range, indicating hypotension.
D. Serum potassium level of 4.8 mEq/L.
The normal serum potassium levels range from 3.6 to 5.2 mEq/L. A serum potassium level of 4.8 mEq/L is within the normal range, so the nurse would not need to withhold furosemide for this reason.

The correct answer is C.
Choice A: Oxygen saturation of 95% The normal oxygen saturation level is between 95% and 100%. An oxygen saturation of 95% is within the normal range, so the nurse would not need to withhold furosemide for this reason.
