Correct Answer: A

Rationale: The correct action the nurse should plan to take when preparing to administer iron dextran IV is to administer a small test dose before giving the full dose. This is done to assess for any allergic reactions that the client may have to the medication. Choice B is incorrect because iron dextran should be infused slowly over a longer period, typically over 1-2 hours to reduce the risk of adverse reactions. Choice C is incorrect because iron dextran administration is more commonly associated with hypotension rather than hypertension. Choice D is incorrect because cyanocobalamin is not used as an antidote for iron dextran toxicity; instead, treatment for iron toxicity may involve supportive care, chelation therapy, or in severe cases, iron antidotes like deferoxamine.

Correct Answer: D

Rationale: Phenazopyridine can turn the urine orange, which is a normal side effect and not a cause for alarm. The client's statement about notifying the provider immediately if their urine turns orange indicates a need for further teaching because it shows a misunderstanding of the medication's side effects. Choices A, B, and C demonstrate a good understanding of the prescribed medications and their effects, indicating the client has grasped the teaching provided on those aspects.

Correct Answer: A

Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.

Correct Answer: C

Rationale: Levothyroxine is the correct answer. In this scenario, the client's elevated TSH and decreased T3 and T4 levels indicate hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine is a synthetic form of thyroid hormone that is used to replace or supplement the body's naturally produced thyroid hormones. Methimazole and Propylthiouracil are used to treat hyperthyroidism by reducing the production of thyroid hormones. Somatropin is a growth hormone used to treat growth hormone deficiency and other conditions unrelated to thyroid disorders.

Correct Answer: C

Rationale: The correct answer is C: Bleeding. Clopidogrel is an antiplatelet medication that works by preventing platelets from sticking together and forming clots. Therefore, one of the main adverse effects of clopidogrel is an increased risk of bleeding. Insomnia (Choice A), hypotension (Choice B), and constipation (Choice D) are not commonly associated with clopidogrel use. Monitoring for signs of bleeding, such as easy bruising, petechiae, or prolonged bleeding from minor cuts, is crucial when a client is taking clopidogrel.
