A nurse is preparing to administer haloperidol 5 mg IM to a client. The amount available is haloperidol 20 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.)

Answer and Explanation

The Correct Answer is ["0.25"]

To calculate the volume of haloperidol solution needed, we can use the formula:

Volume (mL)=Dose (mg)/Concentration (mg/mL)

Given: Dose of haloperidol = 5 mg

Concentration of haloperidol solution = 20 mg/mL

Substituting the given values into the formula:

Volume (mL)=5 mg/20 mg/mL

Volume (mL)=5/20

Volume (mL)=0.25 mL

Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.

Correct Answer is D

Explanation

A. The client's blood pressure is within the expected reference range - While blood pressure monitoring is important during treatment with certain medications, such as antihypertensives, it is not a direct indicator of the effectiveness of sertraline, which is an antidepressant medication.

B. The client's legs are not swollen - Swelling of the legs may be a sign of fluid retention, which can occur with various conditions and medications. However, it is not a specific indicator of the effectiveness of sertraline.

C. The client reports a recent weight loss - Weight changes, including weight loss or gain, can occur as side effects of sertraline. However, weight changes alone do not necessarily indicate the effectiveness of the medication in treating depression.

D. The client reports an increase in mood - Improvement in mood, reduction in depressive symptoms, and overall sense of well-being are primary indicators of the effectiveness of sertraline and other antidepressant medications in treating depression. Therefore, the client reporting an increase in mood suggests that the medication may be effective in managing their symptoms.

A. Avoid flossing the teeth to prevent gum irritation. B. Alcohol increases the chance of phenytoin toxicity. C. Take an antacid with the medication if indigestion occurs. D. Phenytoin turns urine blue.

Correct Answer is B

Explanation

A. Avoid flossing the teeth to prevent gum irritation: There is no evidence to suggest that flossing the teeth increases the risk of gum irritation with phenytoin use. In fact, proper dental hygiene, including flossing, is essential to prevent gum disease, which can be exacerbated by the medication.

B. Alcohol increases the chance of phenytoin toxicity: Consumption of alcohol can increase the risk of phenytoin toxicity by enhancing its effects. Therefore, clients taking phenytoin should avoid alcohol consumption to prevent adverse effects and ensure the medication's efficacy.

C. Take an antacid with the medication if indigestion occurs: Phenytoin can interact with antacids, reducing its absorption and effectiveness. Therefore, clients should not take antacids concurrently with phenytoin unless directed by their healthcare provider.

D. Phenytoin turns urine blue: Phenytoin does not typically cause changes in urine color. This statement is incorrect and not relevant to the client's medication regimen.
