Correct Answer: C

Rationale: The sudden sharp pain in the midepigastric region with a rigid boardlike abdomen in a patient with a bleeding gastric ulcer indicates a perforation of the ulcer. Perforation leads to leakage of gastric contents into the peritoneal cavity, causing peritonitis. This presentation requires immediate surgical intervention. Option A is incorrect as intestinal development does not correlate with the symptoms described. Option B is incorrect because inflammation of the esophagus would not lead to a rigid boardlike abdomen. Option D is incorrect as the sudden onset of symptoms is more indicative of a complication like perforation rather than the development of additional ulcers.

Correct Answer: D

Rationale: The correct answer is D: Hypovolemia and shock. Rationale: 1. Low blood volume leads to decreased blood pressure and rapid heart rate as compensatory mechanisms. 2. These signs indicate inadequate perfusion due to reduced blood volume. 3. Hypovolemia can progress to shock if not addressed promptly. Summary: A: Compression of blood vessels is not directly related to low blood volume. B: Increasing circulating blood volume would not occur in a client with low blood volume. C: Inadequate renal perfusion is a consequence of hypovolemia, not an implication of decreasing blood pressure and rapid heart rate.

Correct Answer: A

Rationale: The correct answer is A: Fluid intake of less than 2,500mL. In diabetes insipidus, the body cannot properly regulate fluid balance, leading to excessive thirst and urination. Successful treatment aims to manage these symptoms by reducing fluid intake to prevent dehydration. Therefore, a decrease in fluid intake indicates successful treatment. Explanation for incorrect choices: B: Blood pressure of 90/50mmHg - Blood pressure is not directly related to the treatment of diabetes insipidus. C: Pulse rate of 126 beats/min - Pulse rate is not a specific indicator of successful treatment for diabetes insipidus. D: Urine output of more than 200mL/hour - In diabetes insipidus, excessive urine output is a symptom of the condition, so an increase in urine output does not indicate successful treatment.

Correct Answer: C

Rationale: The correct answer is C: Break the task down into simple steps. This response is the best because it helps the patient by breaking down the task into manageable parts, making it less overwhelming and more achievable. By providing clear and simple steps, the patient can focus on one aspect at a time, reducing frustration and increasing the likelihood of successful completion. Choice A is incorrect because performing the task for the patient does not promote independence or skill development. Choice B is incorrect as it dismisses the patient's feelings of frustration without offering a solution. Choice D is incorrect because having another patient demonstrate may not address the specific needs and abilities of the recovering stroke patient.

Correct Answer: C

Rationale: The correct answer is C: Serum calcitonin level. Smoking can elevate serum calcitonin levels due to the effect of nicotine. However, an elevated serum calcitonin level is not a general indicator of cancer. Step 1: Understand that smoking can increase serum calcitonin levels. Step 2: Recognize that elevated serum calcitonin levels are not specific to cancer and can be influenced by other factors. Step 3: Differentiate between a marker that is specific to cancer (such as carcinoembryonic antigen) and one that can be affected by smoking but not necessarily indicative of cancer (serum calcitonin). Thus, while smoking can elevate serum calcitonin levels, it is not a reliable indicator of cancer.
