Correct Answer: D

Rationale: Rationale: 1. Rapid infusion of hyperalimentation solutions can lead to circulatory overload due to increased fluid volume in the circulatory system. 2. Circulatory overload can result in symptoms such as hypertension, tachycardia, and edema. 3. Hypoglycemia can occur as a result of excess insulin release due to the sudden increase in glucose from the hyperalimentation solution. Summary: A. Cellular dehydration and potassium: Incorrect. Rapid infusion would lead to fluid overload, not dehydration. B. Hypoglycemia and hypovolemia: Incorrect. Hypovolemia is unlikely with rapid infusion, and hypoglycemia is a possible side effect. C. Potassium excess and CHF: Incorrect. Rapid infusion may cause circulatory overload, not CHF, and potassium excess is not a common side effect. D. Circulatory overload and hypoglycemia: Correct. These are the most likely side effects of rapid

Correct Answer: B

Rationale: The correct answer is B. Mr. Sy's statement indicates he understands the pre-operative fasting instructions, which is crucial to prevent aspiration during surgery. Not eating after midnight reduces the risk of complications. A: Incorrect. Wearing a pneumatic compression device post-surgery is important, but this statement does not demonstrate understanding of pre-surgery preparations. C: Incorrect. Knowing the skin preparation site size does not indicate understanding of the surgery process. D: Incorrect. Signing the consent form at the operating table may indicate lack of understanding of the consent process and timing. In summary, choice B is correct as it shows Mr. Sy's awareness of the fasting requirement before surgery, which is crucial for a safe operation.

Correct Answer: C

Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.

Correct Answer: C

Rationale: Rationale for correct answer C: In Hashimoto's thyroiditis, an autoimmune disorder causing hypothyroidism, we expect to see normal to elevated TSH levels due to the pituitary gland stimulating the thyroid to produce more hormones. T4 and T3 levels may be within normal range or slightly decreased. Choice C reflects this pattern with T4 at 22 ug/dl, T3 at 200 ng/dl, and TSH at 0.1 uIU/ml. Summary of why other choices are incorrect: - Choice A: T4 and T3 levels are higher than expected in Hashimoto's thyroiditis, and TSH should be elevated, not stated as normal. - Choice B: An undetectable TSH level is typically seen in hyperthyroidism, not hypothyroidism like Hashimoto's. - Choice D: T4 and T3 levels are significantly lower than expected, and TSH is much higher than typically seen in Hashimoto's

Correct Answer: A

Rationale: The correct answer is A: Assessment. The nurse made an error in the assessment phase by not communicating the patient's condition promptly. Assessment involves collecting data and recognizing changes in the patient's condition. By not informing the nurse about feeling dizzy and light-headed, the nurse missed crucial information that could have indicated a deteriorating condition. The other choices are incorrect because: B: Diagnosis comes after assessment and involves analyzing data to identify the patient's problems. C: Implementation is the phase where nursing interventions are carried out based on the diagnosis. D: Evaluation is the final phase where the nurse assesses the effectiveness of interventions and outcomes.
