Correct Answer: B

Rationale: The correct answer is B: Fluid volume deficit. In a client with ulcerative colitis experiencing frequent diarrhea, the priority nursing diagnosis is addressing the potential fluid volume deficit due to significant fluid loss. Maintaining adequate hydration is crucial to prevent complications associated with dehydration. While choices A, C, and D can also be concerns for a client with ulcerative colitis, addressing fluid volume deficit takes precedence as it directly impacts the client's physiological stability and can lead to serious complications if not managed promptly.

Correct Answer: C

Rationale: Continuing to monitor the fluid output is the appropriate action in this situation. Monitoring the fluid output helps the nurse assess the client's ongoing response to the procedure and detect any sudden changes, such as increased or decreased drainage rate, which could indicate complications. Palpating for abdominal distention, sending fluid to the lab for analysis, or clamping the drainage tube are not necessary actions at this point, as the priority is to monitor the client's condition post-procedure.

Correct Answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

Correct Answer: B

Rationale: The correct answer is B: Pain for 3 consecutive months. Recurrent abdominal pain (RAP) is characterized by abdominal pain that occurs at least once per week for at least 2 months before diagnosis. Choosing option A is incorrect since morning headaches are not a common characteristic of RAP. Option C is incorrect because febrile episodes in the late afternoon are not typically associated with RAP. Option D is incorrect as diaphoresis (excessive sweating) when attacks occur is not a common finding in RAP.

Correct Answer: A

Rationale: The correct answer is A. When caring for a client with Meniere's disease, the highest priority nursing problem is the potential for injury related to vertigo. Meniere's disease is characterized by symptoms like vertigo, which can increase the risk of falls and injuries. Ensuring the client's safety and preventing falls take precedence over other concerns. Choices B, C, and D are not the highest priority because they do not directly address the immediate risk of harm associated with vertigo and falls.
