An anxious adult patient is experiencing a respiratory rate of 40 breaths/min. The most appropriate intervention that the nurse could do is to instruct the patient to:
pant with mouth open
sit up
lie down
breathe through a re-breather mask
The Correct Answer is B
Choice A reason: Panting with mouth open is not an appropriate intervention for an anxious patient with a high respiratory rate. This could increase the risk of hyperventilation and respiratory alkalosis, which could worsen the anxiety and cause symptoms such as dizziness, tingling, and muscle spasms.
Choice B reason: Sitting up is an appropriate intervention for an anxious patient with a high respiratory rate. This could help the patient relax and breathe more deeply and slowly, which could reduce the anxiety and normalize the blood gas levels.
Choice C reason: Lying down is not an appropriate intervention for an anxious patient with a high respiratory rate. This could make the patient feel more claustrophobic and increase the anxiety and the respiratory rate.
Choice D reason: Breathing through a re-breather mask is not an appropriate intervention for an anxious patient with a high respiratory rate. This could increase the oxygen concentration in the blood, which could reduce the stimulus for breathing and cause respiratory depression.

Correct Answer is A
Explanation
Choice A reason: Narrow, peaked T waves are a sign of hyperkalemia, which is a high level of potassium in the blood. Potassium is an electrolyte that affects the electrical activity of the heart. Hyperkalemia can cause the T waves, which represent the repolarization of the ventricles, to become narrow and peaked, indicating a rapid and excessive repolarization.
Choice B reason: ST elevation is a sign of myocardial infarction, which is a heart attack. It indicates that the myocardium, or the heart muscle, is damaged and deprived of oxygen. ST elevation is not related to the potassium level, but rather to the coronary artery blood flow.
Choice C reason: Peaked P waves are a sign of atrial hypertrophy, which is an enlargement of the atria, the upper chambers of the heart. It indicates that the atria are under increased pressure or workload. Peaked P waves are not related to the potassium level, but rather to the atrial function.
Choice D reason: Prominent U waves are a sign of hypokalemia, which is a low level of potassium in the blood. Potassium is an electrolyte that affects the electrical activity of the heart. Hypokalemia can cause the U waves, which represent the repolarization of the Purkinje fibers, to become prominent and visible, indicating a delayed and prolonged repolarization.
Correct Answer is C
Explanation
Choice A reason: This is a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice B reason: This is also a low value for serum calcium, which indicates hypocalcemia. Hypocalcemia can cause muscle spasms, tetany, seizures, and cardiac arrhythmias.
Choice C reason: This is the normal range of serum calcium in adults. Calcium is essential for bone health, muscle contraction, nerve transmission, and blood clotting.
Choice D reason: This is a high value for serum calcium, which indicates hypercalcemia. Hypercalcemia can cause nausea, vomiting, constipation, confusion, lethargy, and kidney stones.
