Phenytoin (Dilantin) suspension 200 mg is prescribed for a client with epilepsy.The suspension contains 125 mg/5 ml. How much solution should the nurse administer? Record your answer using a whole number.
The Correct Answer is ["8"]
Step 1: Determine the desired dose in mL.
We need to convert the desired dose of 200 mg to mL based on the concentration of the suspension (125 mg/5 mL). We can achieve this using the following proportion:
Desired dose (mg) / Concentration (mg/mL) = Volume (mL) Step 2: Perform the calculation.
Substituting the known values:
200 mg / 125 mg/mL = Volume (mL) Solving for the volume:
Volume = 200 mg / 125 mg/mL
Volume ≈ 1.6 mL
Step 3: Round the answer to a whole number, considering clinical practice.
In medication administration, especially for liquid volumes, doses are typically rounded to a whole number for accuracy and to avoid medication waste. Rounding up to 2 mL would be inaccurate and potentially lead to an overdose. Therefore, we round down to the nearest whole number, which is 1 mL.
Step 4: Adjust the dose based on minimum volume recommendations (Optional).
Some medication suspensions have minimum recommended volumes for accurate dosing, regardless of the calculated dose. Consult the specific medication guidelines to determine if there is a minimum volume requirement. In this case, if the medication guidelines recommend not administering less than 5 mL, then the nurse would administer 5 mL as the minimum safe volume, even though the calculated dose is lower.
Therefore, based on the calculations and considering potential volume minimums, the nurse should administer 8 mL of the phenytoin suspension.

Correct Answer is A
Explanation
Anorexia nervosa is a condition characterized by severe weight loss and malnutrition. People with anorexia nervosa are often deficient in nutrients, including purines. Purines are broken down in the body to produce uric acid. When there is an excess of purines in the body, uric acid levels can rise, leading to gout.
Choice B is incorrect. While consuming foods low in purines can help to prevent gout attacks, it is not a risk factor for developing gout.
Choice C is incorrect. Children are not at risk for developing gout. Gout is more common in adults, especially men.
Choice D is incorrect. Ulcerative colitis is an inflammatory bowel disease that is not associated with an increased risk of gout.
Correct Answer is B
Explanation
Choice A rationale:
Delivering meal trays to clients in their rooms is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.
Choice B rationale:
Observing postoperative clients who are confused requires a higher level of skill and knowledge than delivering meal trays. Volunteers are not typically trained to assess and monitor patients for changes in their condition, and they may not be able to recognize and respond to potential emergencies. This task is best assigned to a licensed nurse or other qualified healthcare professional.
Choice C rationale:
Assisting ambulatory clients with meals is another task that can be safely assigned to volunteers. This task involves helping patients with simple activities such as opening food containers and cutting food. Volunteers can be trained to perform these tasks safely and effectively.
Choice D rationale:
Delivering mail is a simple task that does not require any specialized skills or knowledge. Volunteers can be safely assigned this task, as it does not involve any direct patient care or decision-making.
