Correct Answer: A

Rationale: The correct answer is A: Bacterial meningitis. Bacterial meningitis is the most significant form due to its potential severity and rapid progression, requiring urgent medical intervention with antibiotics. Bacterial meningitis can lead to serious complications such as brain damage or death if left untreated. Septic meningitis (choice B) refers to meningitis caused by a systemic infection spreading to the meninges. Aseptic meningitis (choice C) is typically viral or non-bacterial in origin, usually milder than bacterial meningitis. Viral meningitis (choice D) is less severe than bacterial meningitis and often resolves on its own without specific treatment.

Correct Answer: A

Rationale: Step 1: Vitamin K is essential for the synthesis of clotting factors in the liver. Step 2: A splenectomy increases the risk of bleeding due to decreased platelet sequestration. Step 3: Preoperative Vitamin K injection helps correct any clotting deficiencies. Summary: - Choice B is incorrect as Vitamin K does not prevent infection. - Choice C is incorrect as Vitamin K does not directly promote healing. - Choice D is incorrect as Vitamin K does not dry secretions.

Correct Answer: A

Rationale: The correct answer is A: Urinary output of 30 ml in an hour. Adequate tissue perfusion is best indicated by a sufficient urinary output, as it demonstrates proper kidney perfusion and function. A low urinary output may suggest inadequate perfusion. Explanation for other choices: B: Central venous pressure reading of 2 cm H20 is not a reliable indicator of tissue perfusion to vital organs. C: Pulse rates alone are not enough to indicate tissue perfusion as they can be influenced by various factors. D: Blood pressure readings alone may not accurately reflect tissue perfusion, especially in the context of fluid replacement therapy.

Correct Answer: C

Rationale: The correct answer is C: Use the smallest needle possible for injections. In a client with thrombocytopenia (low platelet count), there is an increased risk of bleeding and bruising. Using the smallest needle possible for injections reduces the risk of causing injury to blood vessels and tissues, minimizing bleeding complications. Limiting visits by family members (choice A) is not directly related to protecting the client's safety. Encouraging wheelchair use (choice B) is not necessary unless indicated for mobility reasons. Maintaining accurate fluid intake and output records (choice D) is important for overall client care but does not directly address the risk of bleeding in thrombocytopenia.
