"I fell down my basement steps last year and broke my hip and had to have a hip replacement.”

“When I was diagnosed with mitral valve prolapse, they had to replace the valve with a prosthetic valve."

Answer and Explanation

Correct Answer : A,D,E

The statements by the client that would require the nurse to notify the health care provider to cancel the MRI procedure are:

● “I had a pacemaker inserted a few years ago because my heart was not beating fast enough.”

● "I fell down my basement steps last year and broke my hip and had to have a hip replacement.”

● “When I was diagnosed with mitral valve prolapse, they had to replace the valve with a prosthetic valve."

These statements indicate that the client has metallic implants or devices in their body, which can be affected by the strong magnetic field of an MRI machine. This can pose a risk to the client’s safety and may interfere with the accuracy of the MRI results.

The other statements do not necessarily require the cancellation of the MRI procedure, but the nurse may need to take additional precautions or provide additional support to ensure the client’s comfort and safety during the procedure.

Here is a detailed explanation of why the other choices do not necessarily require the cancellation of the MRI procedure:

● “I have such terrible anxiety, I don’t know if I can remain still throughout the procedure.”: While anxiety can make it difficult for a client to remain still during an MRI procedure, it does not necessarily require the cancellation of the procedure. The nurse may provide additional support or medication to help the client manage their anxiety and remain still during the procedure.

● “I have diabetes mellitus type and have been taking insulin for many years.”: Having diabetes and taking insulin does not necessarily require the cancellation of an MRI procedure. The nurse may need to take additional precautions to ensure that the client’s blood sugar levels are stable during the procedure, but it does not pose a direct risk to the client’s safety or interfere with the accuracy of the MRI results.

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.

Correct Answer is ["1.25"]

Explanation

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.
