A nurse is preparing to administer liquid famotidine 20 mg PO every 6 hr for GERD. Available is famotidine 40 mg/5 ml. How many ml. should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
To determine how many milliliters (ml) should be administered per dose, we need to calculate the dose volume using the available concentration of famotidine.
Given:
Famotidine concentration: 40 mg/5 ml
Dose: 20 mg
We can set up a proportion to solve for the volume:
40 mg / 5 ml = 20 mg / x ml
Cross-multiplying the proportion, we get:
40 mg * x ml = 20 mg * 5 ml
Simplifying, we have:
40x = 100
Dividing both sides by 40, we find:
x = 100 / 40
x ≈ 2.5 ml
Therefore, the nurse should administer approximately 2.5 ml of famotidine per dose.

Correct Answer is D
Explanation
When collecting a urine specimen via straight catheterization, it is important to use a sterile specimen container to maintain the integrity of the sample and prevent contamination. Using a non-sterile container can introduce bacteria and affect the accuracy of the culture and sensitivity results.
The other options mentioned are incorrect:
Using sterile water to inflate the balloon: This action is relevant when inflating the balloon of an indwelling urinary catheter, but in a straight catheterization, there is no balloon involved.
Instructing the client to clean from front to back with an antiseptic solution: This instruction is appropriate for cleaning the urethral meatus before inserting an indwelling urinary catheter, but in a straight catheterization, the nurse performs the procedure using sterile technique and does not require the client to clean themselves.
Collecting urine from the catheter's port: In a straight catheterization, the nurse collects urine directly from the catheter tube using a sterile syringe or collection container, rather than from a separate port.
Correct Answer is A,B,C,D,E
Explanation
When removing personal protective equipment (PPE) after caring for a client in contact isolation, the nurse should follow the steps in the following order:
1. Remove gloves.
2. Remove protective eyewear.
3. Remove gown.
4. Remove mask.
5. Perform hand hygiene.
By following this sequence, the nurse ensures that the removal of PPE is done in a way that minimizes the risk of contamination. Removing gloves first helps prevent the spread of potential contaminants on the hands. Removing protective eyewear next avoids any potential contact with the face or eyes during the removal process. Removing the gown comes next, followed by the mask. Lastly, performing hand hygiene after removing all PPE helps ensure the hands are thoroughly cleaned.
