A nurse is preparing to administer haloperidol 0.5 mg by mouth to an older adult client. The amount available is haloperidol oral concentrate 2 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.25"]
To calculate the amount of haloperidol oral concentrate the nurse should administer, we can use the following equation:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
In this case, the dose is 0.5 mg and the concentration of the haloperidol oral concentrate is 2 mg/mL.
Volume (mL) = 0.5 mg / 2 mg/mL
Volume (mL) = 0.25 mL

Correct Answer is B
Explanation
The nurse should describe hyperactive bowel sounds as sounds that are loud, high-pitched, and increased in frequency and intensity. They are more frequent than the normal bowel sounds, with a rapid succession of sounds occurring at a rate greater than 5 to 30 sounds per minute.
Hyperactive bowel sounds can be heard in conditions such as gastroenteritis, diarrhea, and early mechanical bowel obstruction. They indicate increased bowel motility and are often associated with increased peristalsis.
To differentiate hyperactive bowel sounds from normal or hypoactive bowel sounds, the nurse can explain that hypoactive bowel sounds are decreased or absent sounds that occur when the bowel motility is decreased, such as in conditions like paralytic ileus or after abdominal surgery. Normal bowel sounds are typically soft, low-pitched, and occur at a rate of 5 to 30 sounds per minute.
Correct Answer is D
Explanation
Montelukast is a medication commonly used for the maintenance treatment of asthma. It is not used for immediate relief of wheezing or acute symptoms. Instead, it is taken on a scheduled basis to help control and prevent asthma symptoms over time. The recommended dosing regimen for montelukast in children is once daily in the evening.
The statement about giving the medication every 2 hours if the child is wheezing is incorrect, as this medication is not meant to be used for immediate relief of symptoms. It is a preventive medication.
The statement about it taking 2 months of scheduled use before the medication is effective is incorrect. While it may take some time for the medication to reach its full effect, improvement in symptoms can often be seen within a few days to weeks of starting treatment.
The statement about stopping the medication if the child is taking a steroid is incorrect. Montelukast can be used in conjunction with other asthma medications, including steroids, as prescribed by the healthcare provider. It is important to follow the prescribed treatment plan and not discontinue any medication without consulting the healthcare provider.
