Correct Answer: C

Rationale: When a nurse assesses a 1-hour postpartum client with a boggy uterus located 2 cm above the umbilicus, it indicates uterine atony. The first action the nurse should take is to massage the fundus. Fundal massage helps stimulate uterine contractions, which will reduce bleeding and prevent postpartum hemorrhage. Taking vital signs, assessing lochia, or administering an oxytocin IV bolus are important interventions but should come after addressing uterine atony through fundal massage.

Correct Answer: B

Rationale: The correct answer is B: Wear a dosimeter badge. When caring for a client with a sealed radiation implant, the nurse should wear a dosimeter badge to monitor radiation exposure. This badge helps measure the amount of radiation the nurse is exposed to during care. Choice A is incorrect because removing dirty linens after double-bagging is not directly related to managing radiation exposure. Choice C is incorrect as there is no specific time limit on visitors mentioned in the context of a sealed radiation implant. Choice D is incorrect as there is no evidence supporting the need for family members to stay a specific distance away from the client.

Correct Answer: C

Rationale: Montelukast is a leukotriene receptor antagonist that helps reduce swelling and mucus production in the airways, making it useful for long-term asthma management.

Correct Answer: B

Rationale: In this scenario, the correct answer is B: Hemorrhage. Fullness in the throat post-thyroidectomy can indicate postoperative bleeding, a critical complication that requires immediate assessment and intervention. Choice A, Hypocalcemia, is incorrect because it does not typically present with fullness in the throat. Choice C, Hypoxia, is not directly related to the symptom described and is not the primary concern in this situation. Choice D, Hypothyroidism, is also incorrect as it is a long-term condition and unlikely to manifest suddenly 4 hours postoperatively with throat fullness.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to discontinue the oxytocin infusion. Contractions occurring every 45 seconds indicate uterine hyperstimulation, which can pose risks to both the client and the fetus. By stopping the oxytocin infusion, the nurse can help prevent further complications. Choices B, C, and D are incorrect because increasing, decreasing, or maintaining the oxytocin infusion can exacerbate the uterine hyperstimulation and increase the risks associated with it.
