Correct Answer: C

Rationale: The correct answer is C because using a mechanical lift is an ergonomic practice that ensures safe body mechanics and prevents injuries. Choice A is incorrect as standing with feet together when lifting a client does not promote proper body mechanics. Choice B is incorrect as raising the client's head of bed before pulling the client up is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's upper chest is a safety measure for assisting with standing but does not address ergonomic principles.

Correct Answer: B

Rationale: The correct answer is B: Bradycardia. Bradycardia, or a slow heart rate, is a common finding in clients with hypothyroidism because of the decreased metabolic rate associated with this condition. Weight gain is also a common symptom of hypothyroidism due to the metabolic changes, making choice A incorrect. Tachycardia, or a rapid heart rate, is typically seen in hyperthyroidism, not hypothyroidism, so choice C is incorrect. Heat intolerance is more commonly associated with hyperthyroidism rather than hypothyroidism, making choice D incorrect.

Correct Answer: B

Rationale: Administering a PRN dose of morphine is the most appropriate action to manage postoperative pain in a client following a colon resection. Morphine is a potent analgesic commonly used to relieve moderate to severe pain, especially in postoperative settings. While assisting the client to change positions in bed, encouraging relaxation techniques, and offering a back massage can provide comfort and support, they may not be sufficient in managing the pain following a major surgical procedure like a colon resection. Therefore, the priority intervention for acute postoperative pain control in this scenario is to administer medication like morphine.

Correct Answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

Correct Answer: D

Rationale: The correct answer is D because contractions every 5 minutes that last 30 seconds indicate that the rate of infusion should be increased. This pattern suggests weak contractions or intervals that are too far apart, requiring an adjustment to improve labor progress. Option A is incorrect as a low urine output is not directly related to the need for an increase in the oxytocin infusion rate. Option B, Montevideo units consistently at 300 mm Hg, is incorrect because it is a measure of intrauterine pressure and does not determine the need for an increase in oxytocin infusion. Option C, FHR pattern with absent variability, is incorrect as it may indicate fetal distress but does not specifically relate to the need for adjusting the oxytocin infusion rate.
