Based on the diagnosis of Dehydration, select which IV solution will be ordered to treat waiting this patient.

5% dextrose in Lactated ringers

0.45% sodium chloride

0.9 Sodium chloride

3% Normal Saline

Answer and Explanation

The Correct Answer is C

0.9% Sodium chloride is a balanced isotonic solution that closely resembles the electrolyte composition of the extracellular fluid. It is commonly used to treat dehydration because it helps restore fluid volume and electrolyte balance in the body.

5% dextrose in Lactated Ringers: This solution is typically used for fluid and electrolyte replacement in patients who have significant fluid losses or imbalances, but it may not be the best choice for dehydration alone.

0.45% sodium chloride: This solution, also known as half-normal saline, has a lower concentration of sodium chloride and is often used for patients who require hypotonic fluids. It may not provide enough electrolyte replacement for a dehydrated patient. 3% Normal Saline: This solution has a higher concentration of sodium chloride and is typically used for specific indications, such as severe hyponatremia or in critical care settings. It is not the first-line choice for treating dehydration.

Correct Answer is B

Explanation

An increased serum potassium level, also known as hyperkalemia, can have adverse effects on the electrical conduction of the heart, potentially leading to life-threatening cardiac dysrhythmias. Therefore, it is crucial to assess the patient's pulse rate and rhythm promptly to identify any abnormal cardiac activity.

Assessing the oxygen saturation (oxygen stats), respiratory rate and depth, and deep tendon reflexes are also important assessments, but they are not the priority in this case. Hyperkalemia primarily affects cardiac function, and prompt identification of any potential cardiac rhythm disturbances is essential to prevent further harm.

A. Relax smooth muscles of the bronchial airway. B. Prevent Infection. C. Suppress the cough. D. Promote Expectoration.

Correct Answer is A

Explanation

Aminophylline is a bronchodilator that belongs to the xanthine derivative class of medications. It works by relaxing the smooth muscles surrounding the bronchial airways, which leads to bronchodilation. By dilating the airways, aminophylline helps to relieve bronchospasm, improve airflow, and facilitate easier breathing.

Prevent Infection: Aminophylline is not an antimicrobial medication, and its primary action is not related to preventing or treating infections.

Suppress the cough: While aminophylline may have some antitussive (cough-suppressing) effects, its primary action is bronchodilation rather than directly suppressing the cough reflex. Promote Expectoration: Aminophylline is not primarily indicated for promoting expectoration (bringing up mucus). It mainly focuses on bronchodilation to improve airflow and relieve bronchospasm.
