A nurse is administering atenolol to a client. Which of the following therapeutic effects should the nurse expect the client to experience?
Resolved sexual dysfunction
Decreased bronchospasms
Decreased blood pressure
Reduction in vertigo
The Correct Answer is C
A. Resolved sexual dysfunction: Atenolol, a beta-blocker, may actually cause sexual dysfunction as a side effect rather than resolving it. It is not prescribed to treat sexual health issues and may worsen libido or erectile function.
B. Decreased bronchospasms: Atenolol is a cardioselective beta-blocker, but even selective agents can potentially worsen bronchospasms in sensitive individuals, especially those with asthma or COPD. It is not used to treat respiratory symptoms.
C. Decreased blood pressure: Atenolol works by blocking beta-1 receptors in the heart, leading to decreased heart rate and cardiac output, which lowers blood pressure. This is a primary therapeutic effect in the treatment of hypertension.
D. Reduction in vertigo: Atenolol is not indicated for the treatment of vertigo. While it may be used in certain off-label cardiovascular-related neurologic symptoms, it is not typically associated with reducing dizziness or balance disturbances.

Correct Answer is A
Explanation
A. Zolpidem 10 mg PO HS:This is the correct and acceptable documentation format. It includes the full drug name, dosage, route, and timing abbreviation ("HS" for bedtime), all of which are permitted and clear in medical documentation.
B. Heparin 10,000 u subcutaneously TID:The abbreviation "u" for units is considered unsafe and prone to misreading (e.g., as a zero). Instead, "units" should be written out to prevent medication errors.
C. Docusate 100 mg PO QD:"QD" is a dangerous abbreviation that can be misread as "QID" (four times daily). The Joint Commission recommends writing "daily" instead to ensure clarity and patient safety.
D. Lorazepam 2 mg PO BID:While mostly acceptable, using "BID" can be risky because it may be misinterpreted. Current best practices encourage writing "twice daily" to reduce ambiguity in documentation.
Correct Answer is ["10"]
Explanation
Calculation:
- Determine the concentration of heparin in the solution.
Total units of heparin = 25,000 units
Total volume of solution = 250 mL
Concentration = 25,000 units / 250 mL
= 100 units/mL.
- Calculate the infusion rate in milliliters per hour (mL/hr).
Desired infusion rate = 1,000 units/hr
Infusion rate (mL/hr) = Desired infusion rate (units/hr) / Concentration (units/mL)
= 1,000 units/hr / 100 units/mL
= 10 mL/hr.
