A client is in the emergency department after being rescued from a house fire. After the initial assessment, the client develops a loud, brassy cough. What intervention by the nurse takes priority?

Allow the client to suck on small quantities of ice chips.

Apply oxygen and continuous pulse oximetry.

Have the respiratory therapist provide humidified room air.

Request an antitussive medication from the physician.

Answer and Explanation

The Correct Answer is B

A. Sucking on small quantities of ice chips is not appropriate in this case as it may worsen the airway obstruction or cause further irritation.

B. Applying oxygen and continuously monitoring the client's pulse oximetry will help ensure that the client's oxygen saturation remains adequate and that they do not experience respiratory distress or hypoxemia due to inhalation injury. Early intervention is crucial to prevent worsening of respiratory status.

C. Humidified room air can help in cases of airway irritation, but the priority is to ensure oxygenation and avoid hypoxia.

D. Antitussive medications may be indicated later, but airway management and oxygenation take precedence.

Correct Answer is C

Explanation

A. Blood glucose elevation is a concern for statins, but it is not a primary reason for questioning the order.

B. A history of high cholesterol is common and would not trigger concern regarding lovastatin.

C. Lovastatin can cause liver toxicity, so elevated liver enzymes are a contraindication or cause for concern when prescribing this medication. The nurse should verify this before starting the medication.

D. A history of peptic ulcers is unrelated to the use of lovastatin and would not be a concern in this case.

A. Test the equipment by delivering a smaller shock at 50 J. B. Administer 2 mg of intravenous epinephrine. C. Make sure that the defibrillator is set to the synchronous mode. D. Ensure that everyone is clear of contact with the client and the bed.

Correct Answer is D

Explanation

A. Testing the equipment with a smaller shock is unnecessary when preparing to defibrillate in an emergency.

B. Epinephrine is used in cases of cardiac arrest with no pulse, particularly in asystole or pulseless electrical activity (PEA), not immediately before defibrillation in ventricular fibrillation.

C. Synchronous mode is used for cardioversion, not for defibrillation. Defibrillation should be delivered in unsynchronized mode.

D. Before delivering a shock, it is essential to ensure that everyone, including the nurse, is clear of the client and any conductive surfaces like the bed. This prevents injury from the electrical shock.
