A nurse is preparing to administer 0800 medications to a client. The medication administration record (MAR) states "phenobarbital" and the medication the pharmacy supplied is pentobarbital. Which of the following actions should the nurse take?

Check the prescription in the client's medical record.

Ask the client if she has any allergies.

Ask the client what medication she took yesterday

Check the client's MAR to see what the client received the day before.

Answer and Explanation

The Correct Answer is A

A.   Checking the prescription in the client's medical record can help confirm the correct medication and dosage prescribed by the healthcare provider. It allows the nurse to verify the intended medication and compare it with what was supplied by the pharmacy.
B.   While asking the client about allergies is important for medication safety, it may not directly address the discrepancy between the listed medication (phenobarbital) and the supplied medication (pentobarbital). Allergies are relevant to ensuring the safety of the medication administration, but they may not provide immediate clarification of the discrepancy.
C.   This action may provide some context about the client's medication history, but it does not directly address the discrepancy between the listed medication and the supplied medication. The focus should be on confirming the correct medication for administration according to the client's current prescription.
D.   This action may provide information about the client's previous medication administration history, but it does not directly address the discrepancy between the listed medication and the supplied medication. The nurse's primary concern should be to verify the correct medication to be administered at the current time.

Correct Answer is D

Explanation

D. The expected therapeutic effect of montelukast is the reduction of bronchial inflammation. By blocking leukotriene receptors, montelukast helps to prevent the constriction of airway muscles, decrease mucus secretion, and reduce inflammation in the airways. This can lead to improved asthma control and symptom management.
A. Montelukast is not indicated for the treatment of gastric acid-related conditions such as gastroesophageal reflux disease (GERD) or peptic ulcers.
B. Montelukast is not typically associated with peripheral vasodilation. Its primary mechanism of action involves blocking the action of leukotrienes, which are inflammatory mediators involved in allergic and asthmatic reactions.
C. Montelukast does not affect white blood cell (WBC) count.

A. Monitor amylase and lipase. B. Give acetylcysteine. C. Obtain a chest x-ray. D. Administer naloxone

Correct Answer is B

Explanation

B. Acetylcysteine, also known as N-acetylcysteine (NAC), is the antidote for acetaminophen overdose. It works by replenishing depleted glutathione stores in the liver and preventing or reversing hepatotoxicity caused by acetaminophen overdose. Acetylcysteine should be administered as soon as possible after an acetaminophen overdose to maximize its effectiveness in preventing liver damage.
A. Monitoring amylase and lipase levels is not directly related to acetaminophen overdose. Amylase and lipase are pancreatic enzymes that are typically monitored to assess pancreatic function and diagnose conditions such as pancreatitis.
C. Obtaining a chest x-ray is not typically indicated for acetaminophen overdose. Acetaminophen overdose primarily affects the liver, and the manifestations are predominantly related to hepatotoxicity.
D. Naloxone is an opioid antagonist used to reverse opioid overdose by blocking opioid receptors. It is not indicated for acetaminophen overdose. Acetaminophen overdose does not involve opioid receptors, and naloxone would not be effective in treating acetaminophen toxicity.
