Correct Answer: D

Rationale: The correct answer is to instruct the client to perform the peak flow test before using any bronchodilators. This is important because it provides the most accurate baseline measurement of lung function. Choice A is not necessarily crucial for the accuracy of the test. Choice B describes the technique for spirometry, not peak flow meter use. Choice C, while important for tracking trends, is not directly related to the accuracy of the initial measurement.

Correct Answer: D

Rationale: Administering methylergonovine intramuscularly helps contract the uterus, reducing the risk of postpartum hemorrhage. Monitoring for signs of infection (Choice A) is important but not directly related to preventing postpartum hemorrhage. Uterine massage (Choice B) is beneficial to prevent uterine atony, but methylergonovine is a more specific intervention to prevent hemorrhage. Applying ice packs to the perineum (Choice C) is helpful for perineal pain and swelling, not for preventing postpartum hemorrhage.

Correct Answer: B

Rationale: The correct answer is B. Albuterol can cause tremors as a common side effect. Instructing the client about this potential side effect is crucial for their awareness and preparedness. Choices A, C, and D are incorrect because taking albuterol before meals, limiting caffeine intake, or taking it at bedtime are not specific instructions related to managing the side effects of albuterol like tremors.

Correct Answer: C

Rationale: The correct answer is C: Thyroid-stimulating hormone (TSH). Monitoring TSH levels is crucial to assess the effectiveness of levothyroxine in clients with hypothyroidism. TSH is produced by the pituitary gland and stimulates the thyroid gland to produce thyroid hormones. In hypothyroidism, where the thyroid gland is underactive, administering levothyroxine helps to normalize thyroid hormone levels. Monitoring TSH levels allows the healthcare provider to adjust the levothyroxine dosage to ensure that thyroid hormone levels are within the therapeutic range. Choices A, B, and D (Calcium, Sodium, and Magnesium) are not directly related to assessing the effectiveness of levothyroxine therapy in hypothyroidism and would not provide relevant information regarding the medication's efficacy.

Correct Answer: C

Rationale: When caring for a client with bipolar disorder experiencing acute mania and having obtained a verbal prescription for restraints, the nurse must ensure to obtain a formal written prescription for restraint within 4 hours. This is crucial to maintain the safety and proper care of the client. Choices A, B, and D are incorrect because renewing the prescription every 8 hours, checking pulse rate every 30 minutes, and documenting the client's condition every 15 minutes do not address the immediate need for a formal restraint prescription within 4 hours to manage the client's acute mania effectively.
