What is the appropriate electrical intervention for a patient with ventricular tachycardia and a pulse?
- A. Defibrillation
- B. Synchronized cardioversion
- C. Pacing
- D. Medication administration
Correct Answer: B
Rationale: Synchronized cardioversion is the correct electrical intervention for a patient with ventricular tachycardia and a pulse. This procedure delivers a synchronized electrical shock to the heart during a specific phase of the cardiac cycle, aiming to restore the heart's normal rhythm. Defibrillation (choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is typically used for bradycardias or certain types of heart blocks. Medication administration (choice D) may be used in some cases, but in the scenario of ventricular tachycardia with a pulse, synchronized cardioversion is the preferred intervention.

What are the manifestations of increased intracranial pressure (IICP)?
- A. Restlessness, confusion, irritability
- B. Severe nausea and vomiting
- C. Elevated blood pressure and bradycardia
- D. Decreased heart rate and altered pupil response
Correct Answer: A
Rationale: The correct manifestations of increased intracranial pressure (IICP) include restlessness, confusion, and irritability. These symptoms are a result of the brain being under pressure inside the skull. Severe nausea and vomiting (Choice B) are more commonly associated with increased intracranial pressure in children. Elevated blood pressure and bradycardia (Choice C) are not typical manifestations of increased intracranial pressure; instead, hypertension and bradycardia may be seen in Cushing's reflex, which is a late sign of increased IICP. Decreased heart rate and altered pupil response (Choice D) are also not primary manifestations of increased intracranial pressure, although altered pupil response, like a non-reactive or dilated pupil, can be seen in some cases.
What is the first nursing action for a patient admitted with chest pain from acute coronary syndrome?
- A. Administer sublingual nitroglycerin
- B. Check the patient's urine output
- C. Administer IV fluids
- D. Obtain cardiac enzymes
Correct Answer: A
Rationale: The correct answer is to administer sublingual nitroglycerin. This is the priority action for a patient admitted with chest pain from acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. Checking the patient's urine output (Choice B) is not the priority in this situation. Administering IV fluids (Choice C) may not be necessary unless indicated by the patient's condition. Obtaining cardiac enzymes (Choice D) is important but is not the initial action needed to address the patient's acute symptoms.
What are the early symptoms of compartment syndrome?
- A. Unrelieved pain, pallor, and pulselessness
- B. Localized redness and swelling
- C. Fever and swelling
- D. Numbness and tingling
Correct Answer: A
Rationale: The correct answer is A: 'Unrelieved pain, pallor, and pulselessness.' Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to reduced blood flow and potential tissue damage. Early symptoms include unrelieved pain (out of proportion to the injury), pallor (pale skin color), and pulselessness (decreased or absent pulses). Choices B, C, and D are incorrect as they do not represent the classic early symptoms of compartment syndrome.
What are the expected signs of compartment syndrome?
- A. Unrelieved pain, pallor, and pulselessness
- B. Fever, swelling, and redness
- C. Muscle cramps and weakness
- D. Redness and itching
Correct Answer: A
Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.
What precaution should be advised to a patient following a cataract surgery?
- A. Wear dark glasses while outdoors
- B. Avoid NSAIDs
- C. Use warm compresses
- D. Apply cold packs
Correct Answer: A
Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.
