A client with a history of peptic ulcer disease is admitted with sudden severe abdominal pain. Which finding indicates the possibility of a perforated ulcer?

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: C

Rationale: The correct answer is C. Insulin should not be stored in the refrigerator at all times; it should be kept at room temperature when in use to avoid irritation at the injection site. Storing insulin in the refrigerator can cause it to thicken and may lead to discomfort upon injection. Choices A and D are correct statements as injecting insulin into the abdomen for faster absorption and rotating injection sites to prevent lipodystrophy are appropriate insulin administration techniques. Therefore, the client does not need further teaching on these aspects.

Correct Answer: C

Rationale: The correct instruction for a client newly diagnosed with hypothyroidism is to take the medication on an empty stomach. This is important because taking levothyroxine on an empty stomach ensures better absorption of the medication. Choice A, taking levothyroxine at bedtime, is incorrect as it does not promote optimal absorption. Choice B, increasing fiber intake to prevent constipation, is important but not the priority when it comes to medication administration. Choice D, taking a double dose if a dose is missed, is dangerous and should never be advised as it can lead to overdose and serious side effects.

Correct Answer: B

Rationale: The correct answer is B. Warmth and redness in the client's arm suggest infection or thrombosis of the arteriovenous fistula, which requires immediate intervention to prevent complications. A thrill (A) is a normal finding in a functional arteriovenous fistula, indicating good blood flow. A bruit (C) is also a normal finding on auscultation of a functioning arteriovenous fistula, indicating proper blood flow. The absence of a bruit (D) may indicate a non-functioning fistula, which would need further evaluation but does not require immediate intervention as warmth and redness do.

Correct Answer: A

Rationale: Providing free blood lead level testing for children should be prioritized as it directly identifies children who are at risk and in need of intervention. This intervention allows for early detection and timely implementation of necessary measures to prevent further lead exposure or address existing poisoning. Distributing pamphlets (choice B) may raise awareness but does not directly identify at-risk children. Conducting home inspections (choice C) is important but may not be as immediate and targeted as blood lead level testing. Educating parents (choice D) is essential but may not directly identify and address individual cases of lead poisoning as testing does.
