A nurse is providing teaching for a client who has diabetes mellitus about the self-administration of insulin. The client has prescriptions for regular and NPH insulins. Which of the following statements by the client indicates an understanding of the teaching?

"I will draw the regular insulin into the syringe first."

"I will store prefilled syringes in the refrigerator with the needle pointed upward."

"I will gently roll the NPH vial between my hands before drawing up the insulin."

"I will insert the needle at a 90-degree angle."

Answer and Explanation

The Correct Answer is A

Choice A reason: Drawing the regular insulin into the syringe first is correct. When mixing two types of insulin, the clear (regular) insulin should be drawn up before the cloudy (NPH) insulin to prevent contamination.

Choice B reason: Storing prefilled syringes with the needle pointed upward can cause air bubbles to move into the insulin, which can alter the dose when injected. The needle should be pointed downward.

Choice C reason: Shaking the NPH vial vigorously is not recommended as it can create air bubbles and affect the insulin dose. Instead, the vial should be gently rolled between the hands to mix the insulin.

Choice D reason: Inserting the needle at a 15-degree angle is incorrect for subcutaneous injections. A 90-degree angle is typically used unless the patient is very thin, in which case a 45-degree angle may be used.

Correct Answer is D

Explanation

Choice A reason: Instructing the client to expect tingling in their extremities is not a standard post-lumbar puncture care instruction. Tingling may be a sign of nerve irritation or damage, which is not an expected outcome and should be reported if it occurs.

Choice B reason: Measuring blood glucose every 2 hours is not related to post-lumbar puncture care unless the client has a specific condition that requires such monitoring. Post-lumbar puncture care focuses on preventing complications such as headaches and monitoring for signs of infection or bleeding.

Choice C reason: Limiting the client's fluid intake is not advised following a lumbar puncture. In fact, increasing fluid intake can help prevent the occurrence of post-lumbar puncture headaches, which are a common complication. Adequate hydration helps replenish cerebrospinal fluid and reduce headache severity.

Choice D reason: Instructing the client to lie flat is the correct action. After a lumbar puncture, it is recommended that the client lies flat for several hours to prevent the leakage of cerebrospinal fluid from the puncture site, which can lead to a spinal headache. Lying flat helps maintain normal cerebrospinal fluid pressure and reduces the risk of headache.

A. Tap the client's facial nerve and note any facial twitching. B. Strike the client's patellar tendon with a percussion hammer and note any increase in response. C. Gently elevate the client's head and note any nuchal rigidity. D. Run a tongue blade on the outside of the client's sole and note any flaring of the toes.

Correct Answer is C

Explanation

Choice A reason: Tapping the client's facial nerve and noting any facial twitching is not a specific assessment for bacterial meningitis. This action is more related to evaluating facial nerve function and is not typically used to diagnose meningitis.

Choice B reason: Striking the client's patellar tendon with a percussion hammer and noting any increase in response is a test for reflexes, which may or may not be altered in bacterial meningitis. An increased response can be seen in various neurological conditions and is not specific to meningitis.

Choice C reason: Gently elevating the client's head and noting any nuchal rigidity is a key part of the focused assessment for bacterial meningitis. Nuchal rigidity, or stiffness of the neck, is a classic sign of meningitis and is assessed by gently lifting the head and attempting to move the chin toward the chest. If the client resists due to pain or stiffness, this could indicate nuchal rigidity associated with meningitis.

Choice D reason: Running a tongue blade on the outside of the client's sole and noting any flaring of the toes, known as the Babinski sign, is used to assess for central nervous system lesions and is not specific to meningitis. While it can be part of a neurological assessment, it does not specifically indicate bacterial meningitis.
