A nurse is preparing to administer a 5 mg IV bolus of metoprolol to a patient for heart rate control.

The available metoprolol injection is 1 mg/mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

Cleaning the catheter after each use with soap and water is a crucial step in preventing infection during self-catheterization.

Choice B rationale

The angle at which the penis should be held during catheter insertion can vary, but a 30 to 45- degree angle is not typically recommended.

Choice C rationale

Performing catheterization when feeling the urge to void is not typically part of the instructions for clean intermittent self-catheterization.

Choice D rationale

Inflating the balloon when the urine flow stops is not a step in clean intermittent self- catheterization. This step is associated with indwelling catheters, not intermittent catheters.

Choice A rationale

Acute laryngotracheobronchitis, also known as croup, is a common childhood condition that is usually caused by a viral infection. The main symptom is a distinctive barking cough. A cool mist tent can help to soothe the inflamed airways and reduce stridor, which is a high-pitched,

wheezing sound caused by disrupted airflow. Therefore, decreased stridor would indicate that the treatment has been effective.

Choice B rationale

While a decreased temperature might indicate a resolution of any underlying infection, it is not directly related to the effectiveness of a cool mist tent in treating acute laryngotracheobronchitis.

Choice C rationale

A barking cough is a symptom of acute laryngotracheobronchitis and does not indicate treatment effectiveness.

Choice D rationale

Improved hydration is important but is not a direct indicator of the effectiveness of the cool mist tent.
