A nurse is performing high-frequency chest compressions using a mechanical chest compression device for a child who has cystic fibrosis. Which of the following findings indicates the treatment has been effective?

The child develops a dry, hacking cough.

The child has increased nasal secretions.

The child has increased sputum production.

The child develops diminished breath sounds.

Answer and Explanation

The Correct Answer is C

A. The child develops a dry, hacking cough: This suggests ineffective clearance of secretions and may indicate a need for further intervention.

B. The child has increased nasal secretions: Nasal secretions are not directly related to the effectiveness of high-frequency chest compressions in clearing pulmonary secretions.

C. The child has increased sputum production: Increased sputum production indicates that the

treatment is effectively mobilizing and clearing mucus from the airways, which is beneficial for a child with cystic fibrosis.

D. The child develops diminished breath sounds: Diminished breath sounds could indicate a complication such as atelectasis or pneumothorax and would not be an expected finding with effective high-frequency chest compressions.

C. Offering solutions for problem-solving may be helpful in general, but it may not directly address the specific symptoms of OCD.

A. Hypotension B. Tachycardia C. Muscle cramps D. Hyperreflexia E. None F. None

Correct Answer is A

Explanation

A. Hypotension occurs because hypermagnesemia causes vasodilation, which lowers blood pressure. Magnesium acts as a smooth muscle relaxant, decreasing vascular resistance and contributing to hypotension. This is a common clinical finding when magnesium levels exceed the normal range.

B. Tachycardia is not expected with hypermagnesemia. Elevated magnesium levels depress the heart's electrical activity, leading to bradycardia (slow heart rate) instead of tachycardia.

C. Muscle cramps are typically associated with hypomagnesemia, which increases neuromuscular excitability. In hypermagnesemia, neuromuscular function is suppressed, leading to muscle weakness rather than cramps.

D. Hyperreflexia is a symptom of hypomagnesemia, not hypermagnesemia. In hypermagnesemia, neuromuscular activity is depressed, resulting in diminished or absent deep tendon reflexes
