A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr. to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mile How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["10"]

Given:

Diphenhydramine syrup: 12.5 mg/5 MLX

Required dose: 25 mg

First, determine the ratio of the available dosage strength to the required dose:

12.5 mg (available dose) / 5 mL (volume) = 25 mg (required dose) / X mL

Cross-multiply to find X (the amount of syrup needed):

12.5 mg X mL = 25 mg 5 mL

Now, solve for X:

X = (25 mg 5 mL) / 12.5 mg

X = 125 / 12.5

X = 10

Therefore, the nurse should administer 10 mL of diphenhydramine syrup to provide a dose of 25 mg to the older adult client with rhinitis.

Correct Answer is A

Explanation

Choice A Reason:

"I will use a skin sealant before I apply the bag." This statement is appropriate. Using a skin sealant before applying the ostomy bag helps protect the skin around the stoma, creating a barrier against irritation and potential leaks from the stool. It demonstrates the client's understanding of preventive measures to maintain skin integrity.

Choice B Reason:

"I will use moisturizing soap to clean around the stoma before applying the bag." This statement is inappropriate. While keeping the area around the stoma clean is important, using moisturizing soap might not be recommended as it can leave residue and interfere with the adhesive properties of the bag. Typically, mild soap and water are recommended for cleansing.

Choice C Reason:

"I will cut the wafer opening one-fourth of an inch larger than the stoma." This statement is incorrect. Cutting the wafer opening one-fourth of an inch larger than the stoma might result in an excessively large opening, potentially leading to leaks or irritation. The ideal size is generally recommended to be as close to the stoma size as possible without causing pressure on the stoma.

Choice D Reason:

"I will need to empty the bag every 4 to 6 hours." This statement is incorrect. While regular emptying of the ostomy bag is necessary, the frequency can vary based on individual needs and stoma output. Some individuals might need to empty it more frequently or less often, depending on their stool output and comfort level.

A. LDL B. INR C. BUN D. Hct

Correct Answer is B

Explanation

Choice A Reason:

LDL (Low-Density Lipoprotein) is incorrect. This is a type of cholesterol and is not specifically monitored in relation to warfarin therapy.

Choice B Reason:

INR (International Normalized Ratio) is correct. Warfarin is an anticoagulant medication, and its dosage needs to be adjusted based on the INR levels. INR monitoring helps assess the clotting tendency of the blood and ensures that the dosage of warfarin is within the therapeutic range to prevent blood clots without causing excessive bleeding.

Choice C Reason:

BUN (Blood Urea Nitrogen) is incorrect. This value is primarily used to assess kidney function and is not directly related to monitoring warfarin therapy.

Choice D Reason:

Hct (Hematocrit) is incorrect. This measures the percentage of red blood cells in the blood and is not directly related to monitoring warfarin therapy for atrial fibrillation.
