A nurse is taking care of a patient that has a new prescription for labetalol (beta blocker). What adverse effect should the nurse include in the medication education?
Hypokalemia
Bleeding
Bradycardia
Seizures
The Correct Answer is C
A) Hypokalemia:
Hypokalemia (low potassium levels) is not a common adverse effect of labetalol. While some medications, such as diuretics, can lead to hypokalemia, labetalol does not typically affect potassium levels directly. Instead, labetalol's primary effects are on blood pressure and heart rate.
B) Bleeding:
Bleeding is not a typical adverse effect of labetalol. Labetalol is a beta blocker that works by blocking beta-adrenergic receptors, which lowers heart rate and blood pressure. It does not interfere with blood clotting or platelet function, so bleeding would not be a concern unless the patient is on other medications that affect coagulation (such as anticoagulants).
C) Bradycardia:
Bradycardia, or a slow heart rate, is a well-known and common adverse effect of beta blockers like labetalol. Labetalol works by blocking the beta-1 adrenergic receptors in the heart, which can reduce heart rate and lower blood pressure. In some individuals, this can result in bradycardia, which could lead to symptoms like dizziness, fatigue, and fainting.
D) Seizures:
Seizures are not a typical adverse effect of labetalol. Although central nervous system effects like dizziness or fatigue can occur due to the blood pressure-lowering effects, seizures are not commonly associated with this medication.

Correct Answer is D
Explanation
A) Use the provider’s initials after the prescription:
Using the provider's initials after the prescription is not an appropriate or standard practice. The nurse should transcribe the prescription accurately and include the provider's full name or identification, but not initials. The nurse is responsible for ensuring the correct interpretation and transmission of the order, and abbreviations or initials could lead to errors or confusion.
B) Repeat the prescription to the provider:
Repeating the prescription to the provider may not be sufficient. It is important to read the prescription back to the provider to ensure that both the nurse and the provider are in agreement about the medication order. Repeating the prescription is a good practice, but it does not provide the same level of verification as reading it back to ensure its accuracy.
C) Write the prescription in shorthand:
Writing prescriptions in shorthand is unsafe and should be avoided. Shorthand can lead to misunderstandings or misinterpretations of the order, which could result in medication errors. The nurse should transcribe the prescription clearly and in full, without using any abbreviations or shorthand, to ensure clarity and accuracy.
D) Read back the prescription to the provider:
Reading back the prescription to the provider is the correct action. This practice, often referred to as "read-back," helps to confirm that the nurse has accurately heard and understood the provider’s order. It is a safety measure that reduces the likelihood of medication errors, especially in high-risk situations like verbal or telephone orders. The nurse should repeat the prescription verbatim, including dosage, route, frequency, and any other relevant details, to ensure it has been transcribed correctly.
Correct Answer is B
Explanation
A) Crushing the medication would release all the medication at once, rather than over time:. Enteric-coated aspirin is designed to bypass the stomach and release the medication in the small intestine to avoid irritation of the stomach lining. Crushing the tablet could potentially release the entire dose all at once, which could lead to gastrointestinal irritation, but this isn't the primary concern. The key issue is that crushing destroys the enteric coating, which is crucial for protecting the stomach.
B) Crushing the medication might cause you to have a stomachache or indigestion:
Enteric-coated medications are specifically designed to protect the stomach lining by delaying the release of the drug until it reaches the small intestine. Crushing the medication would destroy the enteric coating, which can lead to stomach irritation, upset, or even ulcer formation due to the direct exposure of the stomach lining to the medication. Therefore, crushing could cause significant discomfort or damage to the digestive system.
C) "Crushing the medication is a good idea, and I can mix in some ice cream for you.":
Crushing enteric-coated medications, such as aspirin, can lead to adverse effects like stomach irritation, ulceration, and poor absorption. The nurse should not recommend this method of administration without first consulting with the prescribing provider or pharmacist to explore alternatives.
D) "Crushing is unsafe, as it destroys the ingredients in the medication.":
Crushing does not destroy the active ingredients in the medication, but it does destroy the enteric coating, which is the key concern. The enteric coating's function is to prevent the aspirin from irritating the stomach. While it's important to recognize that crushing is unsafe, the reason is more about the loss of this protective coating rather than the destruction of the medication's active ingredients themselves.
