Stacy is discharged from the hospital following her chemotherapy treatments. Which statement of Stacy's mother indicated that she understands when she will contact the physician?

Correct Answer: B

Rationale: The correct answer is B: "I will call my doctor if Stacy has persistent vomiting and diarrhea". Rationale: 1. Persistent vomiting and diarrhea are common side effects of chemotherapy that can lead to dehydration and other complications. 2. Contacting the physician in this case shows understanding of the need for immediate medical attention. 3. Prompt communication with the doctor can help in managing these side effects effectively and prevent further complications. Summary: A: Difficulty in sleeping is a common side effect of chemotherapy but does not require immediate medical attention. C: Irritability and unhappiness are subjective symptoms and may not indicate a serious medical issue. D: Continued hair loss is a known side effect of chemotherapy but does not require immediate medical attention unless excessive.

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.

Correct Answer: A

Rationale: The correct answer is A: Delirium tremens. These symptoms are characteristic of delirium tremens, a severe form of alcohol withdrawal. Increased tremors, irritability, hypertension, and fever are signs of worsening withdrawal symptoms that can progress to delirium tremens, a life-threatening condition. Delirium tremens is a medical emergency that requires immediate intervention to prevent complications such as seizures and cardiovascular collapse. Korsakoff's syndrome (B), Esophageal varices (C), and Wernicke's syndrome (D) are all associated with chronic alcohol use, but they do not present with the acute symptoms described in the scenario.
