Order: Digoxin 0.25 mg

On hand: 250 mcg tablets

How many tablets will the nurse give?

Choice A reason: This choice is correct because blood glucose is the priority assessment for a client with a prescription for glipizide who is confused, diaphoretic, and tachycardic. Glipizide is a medicine that lowers blood sugar levels in the body. It can cause side effects such as anxiety, diarrhea, nausea, and low blood sugar. Low blood sugar (hypoglycemia) can cause confusion, sweating, fast heart rate, dizziness, hunger, and seizures. The nurse should check the client's blood glucose level and treat hypoglycemia as soon as possible.

Choice B reason: This choice is incorrect because apical heart rate is not the priority assessment for a client with a prescription for glipizide who is confused, diaphoretic, and tachycardic. Apical heart rate is the number of heartbeats per minute that can be heard at the apex of the heart. It can be affected by many factors, such as age, activity, stress, and medication. Tachycardia is a condition where the heart beats faster than normal, which can be a sign of low blood sugar, dehydration, infection, or heart problems. The nurse should check the apical heart rate after assessing and treating the blood glucose level.

Choice C reason: This choice is incorrect because INR level is not the priority assessment for a client with a prescription for glipizide who is confused, diaphoretic, and tachycardic. INR stands for international normalized ratio, which is a measure of how long it takes the blood to clot. It is used to monitor the effect of anticoagulant drugs, such as warfarin, that prevent blood clots. Glipizide does not affect the INR level, and the client's symptoms are not related to bleeding or clotting. The nurse should check the INR level only if the client is taking anticoagulant drugs and has signs of bleeding or clotting.

Choice D reason: This choice is incorrect because the last bowel movement is not the priority assessment for a client with a prescription for glipizide who is confused, diaphoretic, and tachycardic. The last bowel movement is the time and nature of the client's most recent defecation. It can be affected by many factors, such as diet, fluid intake, activity, medication, and bowel habits. Glipizide can cause diarrhea or constipation, which can affect the frequency and consistency of the bowel movement. The nurse should check the last bowel movement after assessing and treating the blood glucose level.

To calculate the amount of heparin to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))

Plugging in the given values:

Amount to administer (mL) = (7,500 units / 10,000 units/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (7,500 / 10,000) = 0.75 mL

So, the nurse should administer 0.75 mL of heparin subcutaneously.
