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

Systematic desensitization is a therapeutic technique used to help individuals gradually overcome their fears or phobias by exposing them to the feared stimulus in a controlled and systematic way. The goal is to reduce anxiety and increase relaxation through a step-by-step process.

The statement "What is the worst that will happen if you confront this fear?" aligns with the principle of systematic desensitization because it encourages the client to explore and challenge their negative beliefs or catastrophic thinking associated with their fear. By questioning the potential negative outcomes, the nurse is helping the client to reevaluate their fear response

and consider more realistic expectations. This process can contribute to the client's ability to confront their fear gradually and reduce anxiety over time.

The other statements are still helpful and supportive, but they do not specifically address the principles of systematic desensitization:

“I can see you are anxious. Let's stop for a minute." acknowledges the client's anxiety but does not actively engage in the technique of systematic desensitization.

"Use the deep breathing techniques we practiced yesterday." focuses on relaxation techniques, which can be helpful in managing anxiety but does not specifically address the principles of systematic desensitization.

“Tell me how you are feeling right now." encourages the client to express their feelings but does not directly engage in the technique of systematic desensitization.

Correct Answer is ["4.54"]

Explanation

To convert pounds (lbs) to kilograms (kg), we need to use the conversion factor: 1 pound = 0.45359237 kilograms

Now, let's calculate the weight of the baby in kilograms:

Weight in kilograms = Weight in pounds * Conversion factor

Weight in kilograms = 10 lbs * 0.45359237 kg/lb

Weight in kilograms ≈ 4.5359237 kg

Therefore, the baby weighs approximately 4.54 kilograms.
