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 ["A","D","E"]
Explanation
A. Electrical cord on floor over a walkway:
An electrical cord on the floor in a walkway poses a significant tripping hazard. Clients may not notice the cord or may have difficulty stepping over it, increasing the risk of falls, particularly for individuals with impaired mobility or vision.
B. Demonstrates correct use of cane to ambulate:
Proper use of a cane improves balance and stability, reducing fall risk rather than contributing to it. Clients who demonstrate correct usage are actively minimizing their likelihood of falling.
C. Grab bar in the bathroom:
Grab bars provide added support and stability, particularly in areas prone to slips, such as bathrooms. Their presence is a preventive measure rather than a fall risk.
D. Diagnosis of Macular degeneration:
Macular degeneration impairs central vision, which can lead to difficulties in detecting obstacles and maintaining balance, increasing the client’s susceptibility to falls.
E. Throw rugs in kitchen:
Throw rugs are a well-documented fall hazard because they can slip, bunch up, or create uneven surfaces. They are particularly risky for older adults and those with mobility impairments.
Correct Answer is A
Explanation
A) Provide a dedicated area for the nurse to prepare medications:
Having a dedicated, quiet area for preparing medications is crucial for reducing the risk of medication errors. A designated space minimizes distractions, ensures proper organization, and allows the nurse to focus on the task at hand, which can help prevent mistakes. It also supports a more organized environment where medications can be checked for accuracy, labels can be read carefully, and correct dosages can be administered. This is the best practice to reduce medication errors.
B) Wait to document medications given to clients until the end of a shift:
Delaying the documentation of medications until the end of a shift increases the risk of forgetting to document or making errors. Medications should be documented immediately after administration to ensure accuracy and prevent omissions. Immediate documentation also provides real-time updates on the client's medication history and avoids any discrepancies between what was actually administered and what is recorded.
C) Remove medications from automatic dispensing systems before they are reviewed by pharmacists:
Removing medications from automatic dispensing systems before they are reviewed by pharmacists increases the risk of errors. Medications should be reviewed by the pharmacist to ensure proper drug selection, dosage, and appropriateness for the patient's condition. Pharmacists play an essential role in medication safety, and bypassing their review increases the likelihood of incorrect medication administration, potentially leading to harmful consequences.
D) Prepare medications for multiple clients at the same time:
Preparing medications for multiple clients simultaneously is risky and can lead to confusion and errors. Nurses should focus on preparing medications for one patient at a time to ensure that the correct medication and dosage are administered to the correct person. This practice reduces the likelihood of mixing up medications or administering the wrong drug or dosage.
