A client with the diagnosis of schizophrenia sitting all alone and talking quietly. Which action should the PN take?

Pilocarpine ophthalmic drops are used to treat glaucoma by reducing intraocular pressure. They do not have an anesthetic effect and are not used for the purpose of numbing or anesthetizing the eyes. It is important for the client to have a correct understanding of the medication and its intended use.
Here's why the other options are incorrect:

A. Reassure the client that the drops will not be needed often since eye pain in glaucoma is not common: This statement is not accurate. While eye pain may not be a common symptom of glaucoma, pilocarpine drops are primarily used to reduce intraocular pressure, not to address eye pain.
B. Reteach the client about the action of the eye drops to decrease pressure in the eyes: This option may be considered if the client misunderstood the information initially, but it is not the most appropriate response in this scenario. The client's statement indicates a specific belief about the drops providing anesthetic effects, so clarifying the purpose of the drops is more appropriate.
C. Document in the chart that the client understands the action and use of the eye drops: Documentation is important, but in this case, it is necessary to address the client's misconception about the anesthetic effect of the drops and provide accurate information.

Regular insulin is the medication of choice for treating DKA. Its main action is to lower blood glucose levels by promoting the uptake of glucose into cells and inhibiting the production of glucose by the liver. Therefore, checking the fingerstick blood glucose level is an important indicator of the effectiveness of the insulin treatment.
A decrease in the blood glucose level indicates that the insulin is working to lower the high blood sugar associated with DKA. This measurement helps the PN assess the response to treatment and adjust the insulin dosage if necessary.
The other actions mentioned are also important assessments in the care of a client with DKA, but they do not specifically evaluate the effectiveness of the insulin dosage:
A. Smelling the client's breath for resolution of a fruity odor is important as it indicates a decrease in ketone production, which is a marker of improving DKA. However, it does not directly evaluate the effectiveness of the insulin dosage.
B. Determining the client's orientation to time and space is part of assessing their neurological status, which is crucial in managing DKA. However, it does not specifically assess the effectiveness of the insulin dosage.
C. Measuring the client's urinary output for an increased volume is important to monitor hydration status and renal function, but it does not directly evaluate the effectiveness of the insulin dosage.
