A nurse is collecting data from a client who is taking an oral contraceptive. Which of the following findings is a contraindication for the use of oral contraceptives?

A. The client's potassium level is 2.7 mEq/L is incorrect. A potassium level of 2.7 mEq/L is low and indicates hypokalemia, which is a life-threatening condition that can occur in anorexia nervosa, particularly if the client is engaging in behaviors like purging. This level should be addressed immediately, not considered a positive outcome.

B. The client resumes menstruation is correct. The resumption of menstruation is a positive outcome of treatment for anorexia nervosa. It indicates that the client's nutritional status has improved and that the body is starting to regain normal function after addressing issues like malnutrition and hormonal imbalances.

C. The client's pulse rate is 44/min is incorrect. A pulse rate of 44/min is bradycardia, which is a common sign of anorexia nervosa due to malnutrition and the body's attempt to conserve energy. While it may improve with treatment, this finding would not be considered a positive outcome.

D. The client develops lanugo is incorrect. Lanugo (fine, soft hair) typically develops in severe anorexia nervosa due to malnutrition and is a sign of starvation. The appearance of lanugo is not a positive outcome but rather a compensatory mechanism to retain heat, indicating that the client is still in a malnourished state.

A. Injecting 15 units of air into the regular insulin vial is correct. When drawing up two types of insulin, the nurse should first inject air into the NPH (cloudy) insulin vial without withdrawing the medication. Then, the nurse should inject air into the regular (clear) insulin vial before withdrawing the regular insulin. This prevents contamination and maintains proper insulin mixing procedures.

B. Placing the cap over the needle is incorrect. Once insulin preparation has started, recapping the needle is unnecessary and increases the risk of contamination or needlestick injury.

C. Verifying the dosage with another nurse is incorrect at this stage. Dosage verification should be done after the correct amounts of insulin are drawn into the syringe, not before.

D. Withdrawing 10 units of NPH insulin is incorrect. The nurse should first withdraw the regular (clear) insulin before drawing up the NPH (cloudy) insulin to avoid contaminating the regular insulin with the longer-acting insulin.
