Lasix 50 mg IV. The available vial contains 80mg/2ml. What is the dose in ml?
The Correct Answer is ["1.25"]
To calculate the dose of Lasix (furosemide) in milliliters (ml), we can set up a proportion using the available concentration and the prescribed dose.
The available concentration is 80 mg/2 ml, which means there are 80 mg of Lasix in 2 ml of solution.
The prescribed dose is 50 mg.
Setting up the proportion:
80 mg / 2 ml = 50 mg / x ml
Cross-multiplying:
80 mg * x ml = 2 ml * 50 mg
80x = 100
Dividing both sides by 80:
x = 100 / 80
x = 1.25
Therefore, the dose of Lasix 50 mg IV would be approximately 1.25 ml.

Correct Answer is D
Explanation
The purpose of asking the client to describe their problems during the assessment is to obtain information about their perception of the problem. By asking the client to describe their problems
in their own words, the nurse gains insight into how the client perceives and understands their current situation. This information helps the nurse to understand the client's subjective experience, their concerns, and their specific needs related to the problem. It allows for a more accurate assessment of the client's situation and helps in developing an individualized plan of care tailored to their unique needs.
● Personal needs: While understanding a client’s personal needs is important in providing care, it is not the primary purpose of this specific question. The nurse may ask other questions to gather information about the client’s personal needs.
● Communication skills: Assessing a client’s communication skills may be important in some cases, but it is not the primary purpose of this specific question. The nurse may use other methods to assess the client’s communication skills.
● Admitting diagnosis: The admitting diagnosis is typically determined by a physician and is based on medical tests and examinations. While the nurse may gather information that can contribute to determining the admitting diagnosis, it is not the primary purpose of this specific question.
Correct Answer is B
Explanation
A. “I can see you are anxious. Let's stop for a minute."This option interrupts the exposure process. In systematic desensitization, the goal is to continue exposure while employing relaxation techniques, so stopping would not promote the gradual reduction of anxiety.
B. “Use the deep breathing techniques we practiced yesterday."This statement encourages the client to utilize a relaxation technique (deep breathing) while facing their fear, which is the core of systematic desensitization. By practicing relaxation in the presence of the feared stimulus, the client learns to associate the stimulus with calmness rather than anxiety.
C. "What is the worst that will happen if you confront this fear?"This option uses a form of cognitive restructuring, which is more aligned with cognitive-behavioral therapy (CBT) rather than systematic desensitization. This focuses on changing thought patterns rather than gradually exposing the person to their fear while inducing relaxation.
D. “Tell me how you are feeling right now."While it is important for the client to reflect on their feelings, this option does not promote relaxation or directly help the client manage their anxiety response during exposure. It focuses more on emotional processing rather than applying the desensitization technique.
