A nurse is preparing to administer morphine 8 mg IV intermittent bolus to a client. The amount available is morphine 10 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.8"]
To calculate the amount of morphine to administer, we can use the following formula:
Amount of medication (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case, the desired dose is 8 mg and the concentration is 10 mg/mL.
Amount of medication (mL) = 8 mg / 10 mg/mL
Amount of medication (mL) = 0.8 mL
Therefore, the nurse should administer 0.8 mL of morphine.

Correct Answer is C
Explanation
A. Lorazepam 2.5mg PO qhs before bed: This transcription suggests a fixed dose to be taken before bed (qhs = every bedtime), which does not align with the "as needed" or PRN (pro re nata) instruction for anxiety.
B. Lorazepam 2.5 mg PO QD at hs: This suggests that the medication should be taken once daily (QD) at bedtime (hs = at hour of sleep), which again is not appropriate for as-needed (PRN) use in anxiety.
C. Lorazepam 2.5 mg PO every 8 hours as needed for anxiety: This transcription correctly indicates that the lorazepam is to be taken as needed for anxiety, with a dose of 2.5 mg. However, this also suggests it can be taken every 8 hours, which is more of a standard timing than PRN use. But, it is still the most accurate option for a PRN order.
D. Lorazepam 2.50 mg PO Q 8 hours for anxiety:This prescription is incorrect because it implies the medication should be taken every 8 hours regardless of need, which conflicts with the as-needed (PRN) nature of the order.
Correct Answer is D
Explanation
Oxybutynin is an anticholinergic medication commonly used to treat urinary incontinence. One of the adverse effects of anticholinergic medications is the potential for bradycardia, which refers to a slower than normal heart rate. Anticholinergic medications can inhibit the effects of acetylcholine, a neurotransmitter responsible for regulating various bodily functions, including heart rate. Therefore, it is important to assess the client for signs of bradycardia after an unintended higher dose of oxybutynin.
Increased salivation (A) is not an expected adverse effect of oxybutynin. In fact, anticholinergic medications like oxybutynin often have the opposite effect, causing dry mouth and reduced salivation.
Hyperthermia (B) is not a typical adverse effect of oxybutynin. It is more commonly associated with other conditions or medications.
Urinary incontinence (C) is the condition that oxybutynin is intended to treat. It is not an adverse effect but rather the therapeutic effect of the medication.
