How does shock typically progress?
- A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
- B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
- C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
- D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours
Correct Answer: A
Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?
- A. It is an acute bowel obstruction.
- B. It is a condition that causes an acute inflammatory process in the bowel.
- C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
- D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.
Correct Answer: D
Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
The patient in the emergency room has a history of alprazolam (Xanax) abuse and abruptly stopped taking Xanax about 24 hours ago. He presents with visible tremors, pacing, fear, impaired concentration, and memory. Which intervention takes priority?
- A. Have the patient lie down on a stretcher with bed rails raised
- B. Offer the patient a cup of water and a small amount of food
- C. Reassure the patient about his well-being
- D. Inform the physician about the patient's Xanax withdrawal
Correct Answer: A
Rationale: The 1-4 day period after Xanax withdrawal is critical as it poses the highest risk of life-threatening seizures. Alprazolam is a benzodiazepine, and sudden cessation can lead to severe withdrawal symptoms. The patient's visible tremors, fear, pacing, and cognitive impairment indicate a state of heightened distress and potential seizure risk. Placing the patient on a stretcher with raised bed rails is essential for seizure precautions, ensuring safety and preventing injury during a potential seizure. Offering water and food, reassuring the patient, or informing the physician about Xanax withdrawal are not immediate priorities compared to managing the risk of seizures in this high-risk situation.
A patient is being visited at home by a healthcare professional. The patient has been taking Naproxen for back pain. Which statement made by the patient most indicates that the healthcare professional needs to contact the physician?
- A. I get an upset stomach if I don't take Naproxen with my meals.
- B. My back pain right now is about a 3/10.
- C. I get occasional headaches since taking Naproxen
- D. I have ringing in my ears.
Correct Answer: D
Rationale: The correct answer is 'I have ringing in my ears.' Ringing in the ears is a severe adverse effect of Naproxen, indicating potential toxicity. This symptom warrants immediate medical attention. Choices A, B, and C are less concerning and do not directly indicate a severe adverse effect or toxicity related to Naproxen. Upset stomach, mild back pain, and occasional headaches are common side effects that may not require immediate physician contact.
You have accompanied the physician into the family waiting room to tell a young husband that his wife has not survived the car accident she was in. The husband is crying and distraught. What is the most appropriate approach to supporting this family member?
- A. Ask if he would like to donate his wife's organs
- B. Sit quietly with him
- C. Ask about funeral arrangements
- D. Consult social services
Correct Answer: B
Rationale: The most caring and supportive approach in a time of extreme distress is usually to sit quietly with the distressed individual until they have had the opportunity to absorb the news and gather themselves. Providing a supportive presence is often the most valuable tool a caregiver can use when circumstances bring overwhelming emotional pain to those they are caring for. Asking about organ donation at this moment may come off as insensitive and should not be a priority. Inquiring about funeral arrangements and consulting social services can be addressed later, once the husband has had time to process the initial shock and emotions.
What is the likely cause of pericarditis in a young patient?
- A. Heart failure
- B. Acute MI
- C. Hypertension
- D. Infectious processes
Correct Answer: D
Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.
