A nurse is reviewing the laboratory report of a client who has hypoparathyroidism. The nurse should expect which of the following values?
Phosphate 5.7 mg/dL
Vitamin D 25 ng/mL
Calcium 9.8 mg/dL
Magnesium 1.8 mEq/L
The Correct Answer is A
Choice A reason: Phosphate 5.7 mg/dL is an elevated value, as the normal range is 2.5 to 4.5 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood.
Choice B reason: Vitamin D 25 ng/mL is a normal value, as the normal range is 20 to 50 ng/mL. Hypoparathyroidism does not directly affect vitamin D levels, but vitamin D supplements may be given to help increase calcium absorption and lower phosphorus levels in the blood.
Choice C reason: Calcium 9.8 mg/dL is a normal value, as the normal range is 8.6 to 10.2 mg/dL. Hypoparathyroidism causes low levels of parathyroid hormone (PTH), which regulates calcium and phosphorus balance in the body. Low PTH leads to low calcium and high phosphorus levels in the blood. However, calcium levels may be normal or near- normal in some cases of hypoparathyroidism, especially if the condition is mild or well-controlled with treatment.
Choice D reason: Magnesium 1.8 mEq/L is a normal value, as the normal range is 1.5 to 2.5 mEq/L. Hypoparathyroidism does not directly affect magnesium levels, but magnesium deficiency can cause or worsen hypoparathyroidism, as magnesium is needed for PTH secretion and action. Magnesium supplements may be given to correct magnesium deficiency and improve PTH function.

Correct Answer is D
Explanation
Choice A reason: Insulin injected into the thigh is not the most rapidly absorbed. The abdomen is the preferred site for insulin injection, as it has the fastest and most consistent absorption rate. The thigh, arm, and butock have slower and more variable absorption rates12.
Choice B reason: The botle of insulin should not be shaken before withdrawing the medication. Shaking can damage the insulin molecules and affect their potency and effectiveness. Instead, the botle should be gently rolled between the palms to mix the insulin evenly13.
Choice C reason: Lantus insulin should not be used immediately before each meal. Lantus is a long-acting insulin that provides a steady basal level of insulin for 24 hours. It should be taken once a day at the same time every day, regardless of meals. Humalog is a rapid-acting insulin that can be used immediately before each meal to cover the postprandial glucose spikes14.
Choice D reason: Unopened vials of insulin should be kept in the refrigerator until needed. This can help preserve their quality and potency until their expiration date. Opened vials of insulin can be kept at room temperature for up to 28 days, depending on the type and brand
Correct Answer is B
Explanation
Choice A reason: Wearing closed-toed shoes daily is a good practice for people with diabetes, as it can protect the feet from injuries and infections. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. These complications are mainly caused by high blood glucose levels that damage the blood vessels and nerves in the eyes and feet.
Choice B reason: Maintaining stable blood glucose levels is the most important action for preventing long-term complications of retinopathy and neuropathy. High blood glucose levels can cause oxidative stress, inflammation, and endothelial dysfunction, which impair the blood flow and oxygen delivery to the eyes and feet. This can lead to nerve damage (neuropathy) and vision loss (retinopathy) over time. Keeping blood glucose levels within the target range can reduce the risk of these complications and slow down their progression if they already exist.
Choice C reason: Planning to have an eye examination once per year is a recommended action for people with diabetes, as it can help detect and treat retinopathy before it causes irreversible damage to the retina. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. Eye examinations cannot prevent retinopathy from occurring or worsening; they can only monitor its status and provide appropriate interventions.
Choice D reason: Examining your feet carefully every day is another recommended action for people with diabetes, as it can help identify and treat any signs of neuropathy, such as numbness, tingling, pain, or ulcers. However, it is not the most important action for preventing long-term complications of retinopathy and neuropathy. Foot examinations cannot prevent neuropathy from occurring or worsening; they can only monitor its status and provide appropriate care.
