The nurse is preparing to administer medications to a 54-year old client. Which medications taken would be affected by the first-pass effect? (Select All that Apply.)
Nitroglycerin 10mg Sublingual Tablet
Morphine 2mg IV (Intravenously)
Famotidine 10mg Tablet
Nitroglycerin 4mg Sublingual Tablet
Acetaminophen 325mg Capsule
Diphenhydramine (Benadryl) 25mg Tablet
Correct Answer : C,E,F
A. Nitroglycerin 10mg Sublingual Tablet:
Nitroglycerin taken sublingually (under the tongue) bypasses the gastrointestinal tract and the liver’s first-pass metabolism. It is designed to act quickly and directly enter the bloodstream through the mucous membranes, avoiding significant first-pass effect.
B. Morphine 2mg IV (Intravenously):
Morphine administered intravenously bypasses the gastrointestinal tract and liver, thus avoiding the first-pass effect entirely. The drug directly enters systemic circulation, providing immediate effect.
C. Famotidine 10mg Tablet:
Famotidine, when taken orally, undergoes significant first-pass metabolism. This means that a portion of the drug is metabolized by the liver before it reaches systemic circulation, affecting its bioavailability.
D. Nitroglycerin 4mg Sublingual Tablet:
Similar to the 10mg sublingual tablet, nitroglycerin administered sublingually bypasses the first-pass effect. The medication enters the bloodstream directly through the mucous membranes in the mouth.
E. Acetaminophen 325mg Capsule:
Acetaminophen, when taken orally, undergoes first-pass metabolism. A significant portion of the drug is metabolized in the liver before reaching systemic circulation, which can impact its overall effectiveness.
F. Diphenhydramine (Benadryl) 25mg Tablet:
Diphenhydramine, taken orally, is also affected by the first-pass effect. As with other oral medications, a part of the drug is metabolized by the liver before reaching systemic circulation, which can affect its efficacy and bioavailability.

Correct Answer is D
Explanation
A) Report the incident immediately to your supervisor upon noticing: Reporting the incident is an important step, but it should come after assessing the client's condition. Immediate assessment of the client's vital signs and overall status takes precedence to address any potential immediate health impacts due to the medication error.
B) Gather reversal agents to administer to the client: Gathering reversal agents is a critical step if the medication administered poses an immediate risk and reversal is necessary. However, this action should follow an initial assessment of the client's condition to determine if reversal is needed.
C) Notify the client's provider immediately while present with the client: Notifying the provider is essential to receive guidance on how to manage the medication error. Nonetheless, the first priority should be to assess the client's condition to provide accurate information to the provider.
D) Assess the client's vital signs: The initial action should be to assess the client’s vital signs and overall condition to determine any immediate effects of the incorrect medication. This assessment helps in identifying if the client is experiencing any adverse reactions or complications, which will guide subsequent actions such as notifying the provider and administering reversal agents if needed.
Correct Answer is B
Explanation
A. This hospital might use a different manufacturer, but the medication is the same:
While it is possible that different manufacturers might produce pills of varying appearances, this response does not directly address the client's concern or involve them in verifying the medication. It's important for the nurse to first understand what the client is accustomed to before providing reassurance about the medication.
B. What does your usual pill look like?:
Asking the client to describe their usual pill is the best response. This approach allows the nurse to verify the medication in question by comparing it to the client’s known medication. It also reassures the client that their concerns are being taken seriously and provides an opportunity for the nurse to check if there has been an error or if the medication is indeed correct.
C. This is the medication prescribed by your provider:
While this statement is factual, it does not directly address the client’s concern about the appearance of the medication. It's important to involve the client in verifying the medication to ensure they are receiving the correct drug and to maintain their trust.
D. This pill is probably from a different lot number than yours at home:
This response assumes the issue is related to the lot number, which may not be the case. It does not involve the client in the verification process or address their specific concern about the appearance of the medication. Providing a more thorough and engaging response would be more appropriate.
