A client receives 8 units of regular insulin at 0730. When should the nurse should be most alert for signs and symptoms of hypoglycemia?

"Between 0930 and 1130."

"Between 1130 and 1330."

"Between 0930 and 1030.

"Between 1130 and 1930."

Answer and Explanation

The Correct Answer is A

A. Regular insulin typically reaches its peak action 2 to 4 hours after administration. Since the insulin was given at 0730, the nurse should be most alert for signs of hypoglycemia between 0930 and 1130 when the insulin is most effective in lowering blood glucose.
B. This time frame is too late for peak action, as regular insulin's peak typically occurs earlier, between 2 to 4 hours after administration.
C. While this is within the range of insulin’s peak effect, it doesn't account for the full duration of potential hypoglycemia. The best window for observing symptoms would extend until 1130.
D. Hypoglycemia is most likely to occur during the peak action of the insulin, which is earlier, not this extended time frame.

Correct Answer is B

Explanation

A. Typically, in hyperglycemia (high blood sugar), sodium may be retained, not decreased, due to the osmotic effect of glucose. Increased urine output can lead to some sodium loss, but it is not the primary concern here.
B. When blood glucose levels exceed the renal threshold (around 180 mg/dL), the kidneys cannot reabsorb all the glucose, and it spills over into the urine. This leads to glucosuria (glucose in urine), which is common in uncontrolled diabetes.
C. Hyperglycemia can initially cause increased potassium levels in the blood due to shifts between intracellular and extracellular compartments. However, increased urination (polyuria) can eventually lead to potassium loss, not decreased potassium in urine.
D. Ketones in the urine (ketonuria) are more commonly seen in type 1 diabetes or in cases of diabetic ketoacidosis (DKA), which is often associated with severe insulin deficiency and fat breakdown. While it's possible to see ketones in type 2 diabetes, this is not typically the first finding with a blood sugar level of 289 mg/dL.

A. "You will immediately start thyroid replacement therapy after radioactive iodine treatment." B. "Your partner can feed breast milk to your baby if you pump it." C. "You can try to get pregnant 2 months after the treatment." D. "You need to avoid close contact with others until you the doctor determines you are no longer emitting radiation from your body."

Correct Answer is D

Explanation

A. While many patients who receive radioactive iodine treatment (RAI) for hyperthyroidism may require thyroid replacement therapy afterward, this is not always immediate. The body’s response to the treatment varies, and thyroid function will need to be monitored. The initiation of thyroid replacement therapy depends on the individual's thyroid levels after treatment.
B. Radioactive iodine is contraindicated during breastfeeding because the iodine can pass into the breast milk, potentially exposing the infant to radiation. Mothers are usually advised to stop breastfeeding and to pump and discard milk for a period after the treatment (usually several weeks).
C. The general recommendation is that women should wait at least 6 months after receiving radioactive iodine treatment before trying to become pregnant, as the radiation could potentially affect fetal development during the first few months following the treatment.
D. After receiving radioactive iodine treatment, patients should limit contact with others (especially pregnant women and young children) for a period of time to reduce the risk of radiation exposure to others. This period varies based on the dose of radioactive iodine used, but patients are typically advised to follow specific precautions until their radiation levels have decreased to a safe level.
