NurseDive Free Nursing Practice Question
Which of the following findings should the nurse expect?
A. Extreme thirst.
Extreme thirst is not a typical finding in a client with hypokalemia. Hypokalemia is an electrolyte imbalance that can lead to symptoms like weakness and irregular heartbeats, but extreme thirst is not a direct result of low potassium levels.
B. Weak, irregular pulse.
"Weak, irregular pulse" is the correct response. Hypokalemia can lead to cardiac arrhythmias, which may manifest as a weak, irregular pulse. Potassium plays a crucial role in maintaining the electrical activity of the heart, and low levels can disrupt normal heart rhythms.
C. Hyperactive bowel sounds.
Hyperactive bowel sounds are not typically associated with hypokalemia. Instead, you might expect diminished or absent bowel sounds in severe cases due to muscle weakness.
D. Hyperactive reflexes.
Hyperactive reflexes are not typically associated with hypokalemia. Instead, hypokalemia can lead to muscle weakness and potentially even paralysis in severe cases.

A home health nurse is visiting a client who has COPD and is receiving oxygen at 2 L/min via nasal cannula.
The client tells the nurse she has been having difficulty breathing.
Which of the following actions is the nurse's priority at this time?
A. Have the client cough and expectorate secretions.
Having the client cough and expectorate secretions is a reasonable intervention for managing respiratory distress, but it is not the top priority. The nurse should first assess the client's overall respiratory status to determine the severity of the problem.
B. Instruct the client to use a pursed-lip breathing technique.
Instructing the client to use a pursed-lip breathing technique is a helpful strategy to improve breathing in some cases. However, it should not be the top priority when a client is experiencing difficulty breathing. Assessment should come first.
C. Increase the oxygen flow to 3 L/min.
Increasing the oxygen flow to 3 L/min without a proper assessment is not advisable. It's essential to evaluate the client's respiratory status before making any adjustments to the oxygen therapy.
D. Evaluate the client's respiratory status.
"Evaluate the client's respiratory status" is the correct response. When a client with COPD and oxygen therapy reports difficulty breathing, the nurse's priority is to assess the client's respiratory status. This assessment will help determine the cause of the breathing difficulty and guide appropriate interventions. The nurse should also check the oxygen saturation levels, respiratory rate, and auscultate lung sounds to assess the severity of the issue.

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.
