A client who has a blood glucose level of 800 mg/dL is to receive insulin intravenously. Which form of insulin is safe for intravenous administration?

Insulin aspart (Novo Log).

Insulin glargine (Lantus).

Insulin lispro (Humalog).

Insulin regular (Humulin-R).

Answer and Explanation

The Correct Answer is D

Insulin regular (Humulin-R) is the only form of insulin that is safe for intravenous administration. This is because it is a short-acting insulin that has a rapid onset and peak time, and does not contain any additives or suspensions that could interfere with the infusion.

Choice A is wrong because insulin aspart (Novo Log) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.

Choice B is wrong because insulin glargine (Lantus) is a long-acting insulin that covers insulin needs for about a full day. It is not suitable for intravenous use because it forms micro-precipitates under the skin that release insulin slowly and steadily.

Choice C is wrong because insulin lispro (Humalog) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.

Correct Answer is ["A","B"]

Explanation

Increased heart rate and decreased blood pressure are common signs of dehydration, as the body tries to compensate for the fluid loss by increasing the heart rate and lowering the blood pressure.

Choice C is wrong because increased temperature is not a typical symptom of dehydration, although it can be a cause of it.

Choice D is wrong because hypoactive muscle responses are not related to dehydration, but rather to neurological or muscular disorders.

Choice E is wrong because alert and oriented is the normal mental status for most people, and dehydration can cause confusion and disorientation in severe cases.

Normal ranges for heart rate and blood pressure vary depending on age, gender, physical activity, and other factors, but generally they are:

Heart rate: 60 to 100 beats per minute for adults
Blood pressure: less than 120/80 mmHg for adults

A. Administer oxygen. B. Start IV fluids. C. Administer pain medication. D. Draw lab work.

Correct Answer is ["A","B","C","D"]

Explanation

A. Administer oxygen. This is the first priority because oxygen can help prevent further sickling of red blood cells and improve tissue perfusion.

B. Start IV fluids. This is the second priority because hydration can reduce blood viscosity and prevent vaso-occlusion.

C. Administer pain medication. This is the third priority because pain is a common and distressing symptom of sickle cell crisis and should be treated with opioids around the clock.

D. Draw lab work. This is the last priority because lab work can help monitor the severity of the crisis and the need for blood transfusions, but it does not directly relieve the patient’s symptoms or prevent complications.
