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 A
Explanation
ECT can cause temporary memory loss, particularly for events occurring around the time of the treatment. The client may experience difficulty remembering details of recent events or conversations. This effect is usually temporary and improves over time.
Neck pain is not a typical adverse reaction to ECT. The procedure itself does not involve manipulation or strain on the neck, and significant neck pain following ECT would be unusual. However, it is essential for the nurse to assess and address any discomfort or pain the client experiences after the procedure.
Voice alteration is not a known adverse reaction to ECT. ECT primarily affects the brain and does not directly impact the vocal cords or voice production.
Tingling of the scalp is not a common adverse reaction to ECT. During the procedure, the client receives a brief electrical stimulus, usually applied through electrodes placed on the scalp. Sensations experienced during the procedure are typically related to the electrical stimulation and are transient.
Correct Answer is C
Explanation
Explanation
C.I should check my heart rate while taking the medication
Timolol is a medication commonly prescribed for the treatment of primary open-angle glaucoma, which is a chronic eye condition characterized by increased intraocular pressure
hacking the heart rate while taking timolol eye drops is important. Timolol belongs to a class of medications called beta-blockers, which can have systemic effects. These medications can enter the bloodstream and potentially affect heart rate and blood pressure. Monitoring the heart rate can help assess for any potential adverse effects of the medication.
Taking a zinc supplement in (option A) is not correct because it is not typically necessary while taking timolol eye drops. Zinc supplementation is not a direct requirement or related to the use of timolol for glaucoma treatment. The client should follow their healthcare provider's instructions regarding medication use and potential dietary modifications, but zinc supplementation is not specifically associated with timolol.
Timolol eye drops in (option B) is not correct because it does not darken the colour of the eyes. The purpose of timolol eye drops is to reduce intraocular pressure by decreasing the production of fluid in the eye. Eye colour changes are not known effects of timolol eye drops.
Timolol eye drops in (option D) is incorrect because it does not dilate the eyes. In fact, they work by reducing intraocular pressure, not by dilating the eyes. Eye dilation is typically achieved with the use of specific eye drops called mydriatics or with the use of specialized ophthalmic instruments during an eye examination.
