Correct Answer: B

Rationale: Step-by-step rationale for choice B being correct: 1. Dehydration leads to electrolyte imbalances, which can exacerbate cardiac dysrhythmias. 2. Small frequent intake of fluids like juices, broth, or milk helps in gradual rehydration without overwhelming the cardiovascular system. 3. This approach allows for better absorption of fluids and nutrients, promoting hydration without causing sudden shifts in electrolyte levels. Summary of why other choices are incorrect: A: Just drinking a glass of water every hour may not address electrolyte imbalances or provide adequate hydration for a client with cardiac dysrhythmias. C: NG replacement may not be necessary if the client can tolerate oral intake, and it is more invasive than needed. D: A rapid IV infusion may lead to sudden changes in electrolyte levels, potentially worsening the dysrhythmias.

Correct Answer: A

Rationale: The correct answer is A: Maintain strict records of intake and output. This is the best way to assess fluid balance in a burn patient because it provides quantitative data on fluid intake and output, helping to monitor for fluid imbalance. Monitoring skin turgor (B) is unreliable in burn patients due to skin damage. Weighing the client daily (C) may not accurately reflect fluid balance changes. Checking for edema (D) is not specific to assessing fluid balance in burn patients. Maintaining intake and output records allows for precise monitoring and early detection of fluid shifts, making it the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B: Have a mammogram annually. Mammograms are recommended by the American Cancer Society for breast cancer screening in women as they are effective in detecting early signs of breast cancer. Mammograms have been shown to reduce mortality rates from breast cancer. Annual mammograms are crucial for early detection and treatment. A: Performing breast self-examination annually is not recommended as a standalone screening method as it has not been shown to significantly reduce mortality rates. C: Having a normal receptor assay annually is not a standard screening test for breast cancer recommended by the American Cancer Society. D: Having a physician conduct a clinical examination every 2 years is not as effective as annual mammograms for detecting early signs of breast cancer.

Correct Answer: B

Rationale: The correct answer is B: Health behavior. Evaluating the patient's demonstration of self-injection assesses their ability to perform a specific health-related action. This choice focuses on the patient's actions and behaviors related to their health, aligning with the scenario provided. Choice A: Health status is incorrect because it refers to the patient's current physical condition, not their ability to perform a specific health action. Choice C: Psychological self-control is incorrect as it pertains to the patient's ability to regulate their emotions and impulses, not their ability to self-administer injections. Choice D: Health service utilization is incorrect as it relates to the frequency and pattern of healthcare services used by the patient, not their ability to perform a specific health behavior.

Correct Answer: A

Rationale: The correct answer is A: 11mEq/L. In renal failure, the kidneys are unable to excrete excess magnesium, leading to hypermagnesemia. The patient's symptoms of stomach distress and ingesting antacids suggest magnesium intake. A Mg level of 11mEq/L aligns with symptoms like flushed face and weakness. Choices B, C, and D are too low for hypermagnesemia symptoms and would not explain the patient's presentation.
