Nurse Alexandra teaches a client about elastic stockings. Which of the following statements, if made by the client, indicates to the nurse that the teaching was successful?

Correct Answer: D

Rationale: The correct answer is D because putting on the elastic stockings before getting out of bed in the morning helps prevent blood pooling in the lower extremities. This statement indicates the client understands the importance of wearing the stockings to promote circulation. Choice A is incorrect because the client should follow the prescribed duration for wearing the stockings, not wait for the physician's instruction to remove them. Choice B is incorrect as wearing stockings while sleeping may not be necessary unless specified by the healthcare provider. Choice C is incorrect as removing the stockings for a prolonged period every four hours may not be recommended as consistent wear is typically more beneficial for circulation.

Correct Answer: D

Rationale: The correct answer is D: Elevated serum aminotransferase. In liver cirrhosis, liver cells are damaged, causing release of aminotransferase enzymes into the bloodstream. Elevated levels of serum aminotransferase, such as ALT and AST, indicate liver damage. Decreased red blood cell count (A) is not specific to liver cirrhosis. Decreased serum acid phosphate level (B) is not a typical indicator of liver cirrhosis. Elevated white blood cell count (C) is more commonly associated with infection or inflammation, not liver cirrhosis.

Correct Answer: D

Rationale: Rationale for Correct Answer D: Furosemide (Lasix) inhibits sodium and water reabsorption in the loop of Henle, leading to diuresis and decreased blood volume, thus reducing blood pressure. This mechanism is specific to loop diuretics like furosemide. Option A is incorrect as furosemide acts on the kidneys, not peripheral blood vessels. Option B is incorrect as furosemide does not directly affect sympathetic cardioacceleration. Option C is incorrect as furosemide does not target angiotensin-converting enzymes, which are related to the renin-angiotensin-aldosterone system.

Correct Answer: B

Rationale: The correct answer is B because the statement implies unrealistic expectations and a lack of understanding of a 3-year-old's developmental stage. At this age, children often require repeated instructions and reminders due to their cognitive and behavioral development. This expectation of immediate compliance could lead to frustration and potentially abusive behavior if the child does not meet these unreasonable demands. Choice A is incorrect because it refers to normal toddler behavior of occasional accidents even after toilet training. Choice C is incorrect as it highlights age-appropriate expectations for a 3-year-old to attempt dressing and feeding independently. Choice D is incorrect as saying "NO" is a common behavior in toddlers as they assert their independence and test boundaries.

Correct Answer: A

Rationale: The correct answer is A because Ritalin is a stimulant that helps improve attention span and concentration in children with ADHD by increasing dopamine levels in the brain. This is the desired effect of the medication. Choices B, C, and D are incorrect because Ritalin commonly causes decreased appetite, insomnia, and increased heart rate as side effects, rather than increased appetite, sleepiness, lethargy, bradycardia, or diarrhea. These side effects are typically temporary and can be managed with dosage adjustments.
