Correct Answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

Correct Answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

Correct Answer: B

Rationale: Renting movies and borrowing books for use during recovery indicates the client is planning restful activities at home, which aligns with appropriate post-chemotherapy care. Choices A, C, and D are incorrect because refusing anti-nausea medication can lead to complications, resuming strenuous physical activity immediately can be harmful, and reporting severe fatigue and inability to perform daily activities may indicate a need for medical attention rather than understanding discharge care needs.

Correct Answer: D

Rationale: The correct answer is D: 'Take the full course of antibiotics, even if symptoms improve.' It is crucial for clients to complete the full course of antibiotics as prescribed to ensure that the infection is fully eradicated and to prevent the development of antibiotic resistance. Choice A is incorrect because antibiotics should not be reserved for severe symptoms only; they should be taken as prescribed. Choice B is incorrect as stopping the medication once symptoms disappear may lead to a relapse of the infection. Choice C is important but not the most crucial teaching point when compared to completing the full course of antibiotics.

Correct Answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.
