A nurse is providing teaching for a client who has diabetes and a new prescription for insulin glargine. Which of the following instructions should the nurse provide regarding this type of insulin?

Choice A reason: This is incorrect because withholding all medications may cause hyperglycemia or ketoacidosis in the patient, especially if they are taking insulin or sulfonylureas. The nurse should consult with the prescriber to adjust the dose or timing of the medications according to the patient's blood glucose level and the duration of the procedure.

Choice B reason: This is correct because contacting the prescriber to clarify orders is the best action by the nurse, as the prescriber can provide specific instructions on how to manage the patient's oral antidiabetic drugs before and after the oral endoscopy. The nurse should also monitor the patient's blood glucose level closely and report any abnormal findings to the prescriber.

Choice C reason: This is incorrect because administering half the original dose may not be appropriate for the patient, as it may cause hypoglycemia or hyperglycemia depending on the type and dose of the medication and the patient's blood glucose level. The nurse should not make any changes to the medication regimen without the prescriber's approval.

Choice D reason: This is incorrect because giving the medication with a sip of water may violate the NPO status of the patient, which is necessary to prevent aspiration or interference with the oral endoscopy. The nurse should not administer any oral medications or fluids to the patient unless the prescriber allows it.

Choice A reason: The client waits 10 min between inhalations is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should wait at least 1 min between inhalations to allow the medication to reach the lungs and avoid overdose.

Choice B reason: The client takes a quick inhalation while releasing the medication from the inhaler is the correct answer. This is the correct way to use an albuterol inhaler. The client should breathe in quickly and deeply while pressing down on the inhaler to release the medication. This ensures that the medication is delivered to the airways and not the mouth or throat.

Choice C reason: The client exhales as the medication is released from the inhaler is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should exhale before using the inhaler, not during or after. Exhaling while using the inhaler can cause the medication to be wasted or to irritate the mouth or throat.

Choice D reason: The client holds his breath for 10 seconds after inhaling the medication is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should hold his breath for only a few seconds after inhaling the medication, not 10 seconds. Holding the breath for too long can cause dizziness, headache, or chest discomfort.
