A nurse is caring for a client who has chronic hypertension. The client's morning vital signs include BP 140/80 mm Hg, heart rate 54/min, and respiratory rate 18/min. Which of the following medications should the nurse plan to withhold?

B. Weight gain can indicate that methimazole is effectively managing the thyroid imbalance. Methimazole is commonly used to treat hyperthyroidism by inhibiting the production of thyroid hormones. Weight gain may occur as a result of restoring thyroid hormone levels to normal, which can lead to a decrease in metabolism and an improvement in symptoms associated with hyperthyroidism, such as unintended weight loss.
A. Increased libido is not typically associated with the effectiveness of methimazole in treating thyroid imbalance. Thyroid dysfunction, whether hyperthyroidism or hypothyroidism, can affect libido, but improvement in libido would not specifically indicate the effectiveness of methimazole.
C. Decreased menstrual flow is not a typical indicator of the effectiveness of methimazole in treating thyroid imbalance. Thyroid dysfunction can affect menstrual cycles, with hyperthyroidism often associated with lighter or irregular menstrual periods. However, improvement in menstrual flow alone would not necessarily indicate the effectiveness of methimazole.
D. Clear breath sounds are not specific to the effectiveness of methimazole in treating thyroid imbalance. While methimazole can help manage symptoms of hyperthyroidism, such as palpitations and shortness of breath, clear breath sounds do not directly indicate thyroid function improvement.

B. The correct angle for insulin injections is typically 90 degrees when administering into areas with adequate subcutaneous tissue, such as the abdomen or thigh.

A. Insulin injections should not be administered rapidly, as this can cause discomfort or bruising at the injection site. Additionally, a 20-gauge needle is too large for insulin injections, which typically require smaller gauge needles.
C. Insulin injections are typically administered using insulin syringes, not tuberculin syringes. Additionally, the recommended angle for insulin injections is 90 degrees, not 15 degrees.
D. The Z-track method is a technique used to minimize medication leakage or staining of the skin when administering certain medications, particularly those with irritating properties or medications given intramuscularly.
