Based on the capillary glucose measurement, a client is to receive 10 units of regular insulin. The client's medication drawer contains one vial of a 70/30 mixture of regular Insulin and Isophane insulin How should the nurse prepare the prescribed dose?

Pull up 30 units from the 70/30 vial, but only administer one third.

Withdraw ten units regular insulin from the 70/30 vial.

Withhold the dose until insulin regular is available on the unit.

Obtain a new vial of regular insulin and withdraw ten units.

Answer and Explanation

The Correct Answer is C

A) Pull up 30 units from the 70/30 vial, but only administer one third: The 70/30 insulin vial contains a mixture of 70% isophane (NPH) insulin and 30% regular insulin. If 30 units of this mixture are drawn, the actual amount of regular insulin would be 30% of 30 units, which equals 9 units. This does not equate to the 10 units of regular insulin required, making this option inaccurate for precise dosing.
B) Withdraw ten units regular insulin from the 70/30 vial: The 70/30 vial provides a fixed ratio of regular to NPH insulin. Extracting 10 units from this vial would not yield exactly 10 units of regular insulin; instead, it would include both types in the specified ratio, leading to an incorrect dosage of regular insulin.
C) Withhold the dose until insulin regular is available on the unit: Since the 70/30 vial contains a mixture and not solely regular insulin, it is necessary to withhold the dose until a vial of regular insulin is available. This ensures that the precise amount of regular insulin needed is administered, avoiding the imprecision and potential errors that could arise from using a mixed insulin vial.
D) Obtain a new vial of regular insulin and withdraw ten units: While obtaining a new vial of regular insulin is the correct approach for ensuring accurate dosing, the option of withdrawing ten units directly from a vial of regular insulin is not feasible if the current medication available is a mixture. This option assumes that the correct type of insulin is already available for use.

Correct Answer is D

Explanation

A. Administer both prescribed medications as scheduled: Given that the client's total calcium level is already elevated (14 mg/dL), administering additional calcium carbonate could exacerbate hypercalcemia. Calcitriol, a form of vitamin D, can also increase calcium levels, so administering it without addressing the high calcium level could worsen the condition.
B. Hold the calcium carbonate, but administer the calcitriol as scheduled: This option is not appropriate because calcitriol can further increase calcium levels, potentially worsening hypercalcemia. Both medications should be reviewed, and their administration should be adjusted according to the client's current calcium status.
C. Hold the calcitriol, but administer the calcium carbonate as scheduled: Holding calcitriol alone would not address the potential for further increasing calcium levels. Calcium carbonate should also be withheld since the client is already hypercalcemic.
D. Hold both medications until contacting the healthcare provider: This is the most appropriate action. The client's elevated calcium level indicates hypercalcemia, which requires careful management. The healthcare provider should be contacted to assess the situation and determine the appropriate course of action to avoid worsening hypercalcemia.

A. Nausea. B. Stridor. C. Headache. D. Pruritus.

Correct Answer is B

Explanation

A) 40-year-old female with frequent vaginal infections: Simvastatin is a medication used primarily to manage cholesterol levels and reduce the risk of cardiovascular diseases. Frequent vaginal infections are not directly related to cholesterol levels or cardiovascular risk. Therefore, this client is unlikely to benefit from education about simvastatin.
B) A 50-year-old male with a history of angina: Simvastatin is a statin medication prescribed to lower cholesterol levels and reduce the risk of cardiovascular events, such as heart attacks and strokes. Since angina is a symptom of coronary artery disease, a condition often related to high cholesterol levels, this client would benefit from education about simvastatin, which can help manage cholesterol and potentially reduce cardiovascular risk.
C) An 18-year-old pregnant female with type 1 diabetes mellitus: Statins, including simvastatin, are generally contraindicated during pregnancy due to potential risks to the developing fetus. Additionally, this client’s primary condition of type 1 diabetes mellitus would not typically be managed with simvastatin alone. Therefore, this client is not the target for simvastatin education.
D) A 75-year-old male with bone cancer: While simvastatin is used for managing cholesterol and preventing cardiovascular events, bone cancer is not directly related to cholesterol levels. The primary focus for this client would be managing cancer-related symptoms and treatments rather than cholesterol levels. Thus, this client would not benefit from education about simvastatin.
