A nurse is caring for a client who has a new prescription for a nitroglycerin transdermal patch. Which of the following actions should the nurse take?
Take the patch off prior to bathing the client.
Monitor for hypertension after application of the patch.
Rotate the application sites of the patch.
Remove the patch every 24 hr
The Correct Answer is C
A. Nitroglycerin patches should not be removed for routine activities like bathing unless specifically instructed.
B. Nitroglycerin is used to treat hypertension, not induce it. Monitoring for hypertension after applying the patch is unnecessary.
C. To prevent skin irritation and tolerance to the medication, it is important to rotate the application sites when using a transdermal patch. This allows the skin to recover and helps maintain the effectiveness of the medication.
D. Nitroglycerin patches are typically worn continuously for 12 to 14 hours and then removed for a 10- to 12-hour nitrate-free interval to prevent tolerance to the medication.

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.
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.
