Correct Answer: D

Rationale: After hemodialysis, muscle cramps can indicate an electrolyte imbalance, such as low potassium or magnesium levels, which requires immediate intervention to prevent potential complications like cardiac arrhythmias. Weight gain of 1 pound, dizziness, and fatigue are common post-hemodialysis symptoms that may not necessarily require immediate intervention unless they are severe or persisting.

Correct Answer: C

Rationale: Involving adolescents in meal planning and preparation is a more effective strategy as it actively engages them in the learning process. This approach allows adolescents to have hands-on experience, make informed choices, and develop a sense of ownership over their dietary decisions. Lecturing about dangers or showing documentaries may not be as engaging or interactive, making it less likely for adolescents to retain and apply the information provided. Distributing pamphlets can be informative but lacks the interactive and experiential aspect that involving them in meal planning and preparation offers.

Correct Answer: B

Rationale: Prioritizing the topic of how to childproof the home is crucial as it provides a holistic approach to safeguarding children from various injuries within the home environment. Childproofing the home addresses a wide range of hazards such as falls, burns, poisoning, and choking incidents. While topics like the benefits of car seats, the importance of helmet use, and ways to prevent drowning are important, childproofing the home covers a broader spectrum of safety measures that can significantly reduce the risk of injuries for children.

Correct Answer: C

Rationale: The correct answer is C. Sudden severe abdominal pain is a key clinical manifestation of a perforated ulcer. The sudden onset of severe pain is concerning for a perforation in the ulcer, which can lead to peritonitis if not promptly addressed. Choices A, B, and D are incorrect because hyperactive bowel sounds, a soft and nondistended abdomen, and a blood pressure of 110/70 mm Hg are not specific indicators of a perforated ulcer. Hyperactive bowel sounds may suggest increased gastrointestinal motility, a soft abdomen may not necessarily indicate a perforation, and a blood pressure of 110/70 mm Hg is within normal limits and does not directly relate to a perforated ulcer.

Correct Answer: B

Rationale: The correct answer is B because planning to take folic acid supplements daily is a proactive step towards preventing folic acid deficiency and reducing the risk of neural tube defects in pregnancy. While choice A is important for dietary knowledge, the direct action of taking supplements is more effective. Choice C, understanding the risks, is good but does not ensure action. Choice D, reading nutrition labels, is helpful but doesn't guarantee intake of folic acid.
