A nurse is collecting data from a client who has diabetes mellitus.
Which of the following findings indicates that the client is experiencing DKA?

Confusion

Polydipsia

Rapid pulse

Clammy skin

Answer and Explanation

Correct Answer : A,B,C

Choice A rationale:

Confusion can be a symptom of Diabetic Ketoacidosis (DKA). DKA is a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones. The condition develops when your body can’t produce enough insulin. Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin, your body begins to break down fat as fuel. This process produces a buildup of acids in the bloodstream called ketones, eventually leading to diabetic ketoacidosis if untreated.

Choice B rationale:

Polydipsia, or excessive thirst, is another common symptom of DKA. High blood sugar levels can cause increased urination, leading to dehydration and an increased feeling of thirst.

Choice C rationale:

A rapid pulse is also a symptom of DKA. This is because the body is trying to compensate for the low amount of fluid in your blood vessels due to dehydration.

Choice D rationale:

Clammy skin is not typically a symptom of DKA. It’s more commonly associated with hypoglycemia (low blood sugar), not hyperglycemia (high blood sugar) which is what occurs in DKA1.

Correct Answer is B

Explanation

Choice A rationale:

Macrolides Macrolides, such as erythromycin and azithromycin, are a class of antibiotics that are typically used to treat infections caused by gram-positive bacteria and some respiratory tract infections. They are not the first line of treatment for urinary tract infections.

Choice B rationale:

Sulfonamides Sulfonamides, such as sulfamethoxazole, are often used to treat urinary tract infections. They work by stopping the growth of bacteria. Sulfonamides are often combined with other antibiotics like trimethoprim to increase their effectiveness. This combination is commonly known as co-trimoxazole.

Choice C rationale:

Carbapenems Carbapenems are a class of antibiotics that are usually reserved for serious infections caused by gram-negative bacteria. While they can be used to treat a variety of infections, they are not typically the first choice for urinary tract infections.

Choice D rationale:

Tetracyclines Tetracyclines are a group of broad-spectrum antibiotics that are effective against a wide range of bacteria. However, they are not typically used for urinary tract infections. They are more commonly used for infections such as acne, chlamydia, and Lyme disease.

Correct Answer is ["0.6 "]

Explanation

Answer and explanation

The question is about calculating the volume of methylnaltrexone to administer to a client. The client needs a dose of 12 mg, and the available methylnaltrexone is 8 mg/0.4 mL.

Let’s calculate the volume step by step:

Step 1: Identify the given values:

Desired dose (D) = 12 mg
Available dose (A) = 8 mg
Volume for available dose (V) = 0.4 mL

Step 2: Use the given values in the formula for calculating the volume to administer:

Volume to administer=Available doseDesired dose×Volume for available dose Step 3: Substitute the given values into the formula:

Volume to administer=(12*0.4)/8

Step 4: Perform the multiplication and division:

Volume to administer=4.8mL/8

Step 5: Simplify the division to find the volume to administer:

Volume to administer=0.6mL

So, the nurse should administer 0.6 mL of methylnaltrexone to the client.
