Correct Answer: B

Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.

Correct Answer: C

Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to report any symptoms of hyperthyroidism. Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate overtreatment or excessive dosing of levothyroxine. Prompt reporting of these symptoms is crucial to prevent serious complications. Choices A and B are not the most critical information related to levothyroxine administration. Instructing the client to take the medication at bedtime or with food can be important for adherence but is not as crucial as monitoring for signs of hyperthyroidism. Choice D is incorrect as discontinuing the medication if feeling well can lead to a relapse of hypothyroidism symptoms.

Correct Answer: A

Rationale: The correct measure for skin care after external radiation treatment is to cleanse the radiated area with water and pat the skin dry. This gentle cleansing without harsh chemicals or friction helps protect the integrity of radiated skin, preventing irritation or further damage. Choice B is incorrect because massaging radiated skin can cause further irritation, which should be avoided. Choice C is incorrect as rinsing with normal saline and covering with a sterile towel may not be necessary and could potentially introduce infection due to excessive moisture. Choice D is incorrect as using a soft washcloth to remove skin markings can be too abrasive for radiated skin, risking damage and irritation.

Correct Answer: B

Rationale: The correct answer is B: 'Between 24 to 28 cm.' Fundal height is expected to be approximately equal to the weeks of gestation, so at 26 weeks, the fundal height should typically range between 24 to 28 cm. Choice A is incorrect because fundal height is not an exact measurement of gestational age in centimeters. Choice C is incorrect as it provides a general description above the umbilicus, which is not specific to 26 weeks gestation. Choice D is incorrect as the fundal height would not reach below the xiphoid process at 26 weeks gestation.

Correct Answer: D

Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.
