Correct Answer: B

Rationale: The correct answer is B: Lung cancer. It causes the most deaths in women because it is often diagnosed at advanced stages when treatment options are limited. Breast cancer, although common, has a higher survival rate. Brain cancer is relatively rare compared to lung cancer. Colon and rectal cancer, while prevalent, do not surpass lung cancer in terms of mortality rates in women.

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: Etiology. Etiology in a nursing diagnosis refers to the cause or contributing factors that lead to the identified problem. In this case, the presence of a large scar over the left side of the face is the underlying cause of the disturbed self-esteem. It directly influences the client's self-perception and self-worth. The problem (B) is the disturbed self-esteem itself, not the scar. Defining characteristics (C) are the signs and symptoms that support the nursing diagnosis. Client need (D) is a broader concept that encompasses the overall needs of the client, whereas etiology specifically focuses on the cause of the problem.

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: Fluid replacement. In end-stage AIDS with Cryptosporidium infection, the client experiences severe diarrhea leading to dehydration and electrolyte imbalances. Fluid replacement is crucial to prevent hypovolemia and maintain electrolyte balance. Adequate hydration supports renal function, prevents further complications, and aids in the elimination of the infectious agent. Pain management (A) may be needed for discomfort but is not the priority. Antiretroviral therapy (B) is essential for managing HIV but does not directly address the immediate issue of dehydration. High-calorie intake (D) is important for overall nutrition but does not address the urgent need for fluid replacement in this situation.
