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
Prednisone can cause blood glucose levels to increase.
The nurse should explain to the client that the reason for checking his blood glucose level is because prednisone, a medication he is receiving, can cause an increase in blood glucose levels. Prednisone is a corticosteroid medication that is commonly used in the treatment of various conditions, including COPD. It has the potential to raise blood glucose levels by promoting gluconeogenesis (the production of glucose from non-carbohydrate sources) and decreasing insulin sensitivity. Monitoring blood glucose levels is important to assess and manage any potential hyperglycaemia or changes in the client's blood sugar levels while on prednisone.
Older adults are not at increased risk for developing type 1 diabetes mellitus in (option A) is incorrect. Type 1 diabetes is an autoimmune condition that typically occurs in childhood or adolescence, and it is characterized by the destruction of insulin-producing cells in the pancreas.
Albuterol treatments, which are used to relieve bronchospasms in clients with COPD, are not known to cause blood glucose levels to decrease in (option C) is incorrect. Albuterol is a beta-2 adrenergic agonist that primarily acts on the respiratory system and does not have a direct effect on blood glucose levels.
Having COPD does not directly cause blood glucose levels to fluctuate in (option D) is incorrect. While there can be various factors that may indirectly affect blood glucose levels in individuals with COPD (e.g., medications, stress, comorbidities), the primary reason for monitoring blood glucose in this case is the use of prednisone.
In summary, the nurse should explain to the client that the blood glucose levels are being checked because prednisone, a medication he is taking for his COPD, can cause an increase in blood glucose levels. This allows for appropriate monitoring and management of any potential hyperglycemia associated with the use of prednisone.
Correct Answer is C
Explanation
Orthostatic hypotension, which is a sudden drop in blood pressure upon standing, can be a side effect of enalapril and may lead to syncope. Instructing the client to rise slowly from a sitting to a standing position helps minimize the risk of a sudden drop in blood pressure and decreases the chances of syncope occurring.
Decreasing fluid intake is not likely to be the cause of syncope related to enalapril. It is important for clients to maintain adequate hydration, especially if they are experiencing side effects such as orthostatic hypotension.
While a low pulse rate may indicate bradycardia, it is not the primary concern in this situation. Orthostatic hypotension leading to syncope is the main issue, and the client should be instructed to rise slowly to prevent it.
While enalapril is an angiotensin-converting enzyme (ACE) inhibitor that can increase potassium levels in the blood, it is not directly related to syncope. Dietary changes should be made under the guidance of a healthcare provider based on individual needs and blood test results.
