Order: cephalexin (Keflex) 0.5 gp.o. qid. Available: cephalexin (Keflex) 250 mg capsules. How many capsules will the nurse administer?

Answer and Explanation

The Correct Answer is ["2"]

To determine the number of capsules the nurse will administer, we need to consider the dosage prescribed and the available strength of the capsules.

The prescription states: cephalexin (Keflex) 0.5 g p.o. qid (four times a day).

Given that the available strength of cephalexin capsules is 250 mg, we need to convert the prescribed dosage from grams (g) to milligrams (mg) to match the capsule strength.

1 g = 1000 mg

0.5 g = 0.5 * 1000 mg = 500 mg

Now we know that the prescribed dosage is 500 mg, and each capsule contains 250 mg.

To calculate the number of capsules needed, we divide the prescribed dosage by the strength of each capsule:

Number of capsules = Prescribed dosage / Capsule strength

Number of capsules = 500 mg / 250 mg

Number of capsules = 2

Therefore, the nurse will administer 2 capsules of cephalexin (Keflex) for each dose.

Correct Answer is C

Explanation

Boarding refers to the practice of holding patients in the emergency department (ED) for extended periods, often beyond the recommended timeframe, due to a lack of available mental health treatment options or appropriate placement. In this scenario, the nurse is notifying the manager about the presence of clients with mental health disorders who have been in the ED for more than 48 hours. This situation suggests that the hospital is likely practicing boarding for these clients.

Boarding of mental health patients in the ED can have significant negative consequences. It can contribute to overcrowding in the ED, leading to delays in care for other patients. It can also compromise the quality of care and exacerbate the distress and discomfort experienced by individuals with mental health disorders. Additionally, it is not an optimal environment for mental health treatment and recovery.

By discussing the issue of boarding with the manager, the nurse is addressing the need for timely and appropriate placement for clients with mental health disorders. This conversation may involve exploring solutions such as improving access to mental health services, establishing dedicated mental health units or crisis stabilization centers, and collaborating with community resources to ensure a smooth transition of care for these clients.

The other options mentioned are not directly related to the issue of clients with mental health disorders being present in the ED for over 48 hours:

● Temporary detaining orders for clients: This refers to legal mechanisms that allow for the temporary detention of individuals with mental health disorders who may pose a risk to themselves or others. While it may be related to the care of these clients, it does not address the issue of prolonged stays in the ED.

● The revolving door for clients: This concept refers to the frequent readmission or return of clients to the ED or hospital due to ongoing mental health issues. While it is a concern in mental health care, it does not specifically pertain to the issue of clients remaining in the ED for an extended period.

● The cost of holding clients in the ED for over 48 hours: While the cost implications of extended stays in the ED are relevant, the primary concern in this scenario is the quality of care, appropriate placement, and the impact on both the clients and the ED's functioning.

Correct Answer is ["1"]

Explanation

To calculate the amount of mL the nurse should administer, we can use a proportion based on the available concentration of digoxin (Lanoxin) and the prescribed dose.

The available concentration is 0.5 mg/2 mL, which means there are 0.5 mg of digoxin in 2 mL of solution.

The prescribed dose is 0.25 mg.

Now we can set up the proportion:

0.5 mg / 2 mL = 0.25 mg / x mL

Cross-multiplying, we have:

0.5 mg * x mL = 2 mL * 0.25 mg

0.5x = 0.5

Dividing both sides by 0.5, we get:

x = 0.5 / 0.5

x = 1

Therefore, the nurse should administer 1 mL of digoxin (Lanoxin) to deliver a dose of 0.25 mg.
