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.

When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?
- A. Rapid bronchospasms
- B. Inflammatory epithelial lesions
- C. Increased secretions
- D. Increased mucosal edema
Correct Answer: A
Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
In a 24-year-old woman, the term used to define uterine bleeding in which there is no menstruation is:
- A. Oligomenorrhea
- B. Amenorrhea
- C. Menorrhagia
- D. Metrorrhagia
Correct Answer: B
Rationale: Amenorrhea is the correct term for the absence of menstrual periods in a woman of childbearing age. It is typically defined as no menstruation for at least three consecutive cycles or six months. Oligomenorrhea refers to infrequent or irregular menstrual periods rather than complete absence. Menorrhagia is characterized by excessive menstrual bleeding, not the absence of menstruation. Metrorrhagia involves irregular, acyclic bleeding between menstrual periods, which is different from the absence of menstruation.
Which of the following diseases or disorders is acute?
- A. Pneumonia
- B. Paralysis
- C. Alzheimer's disease
- D. Diabetes
Correct Answer: A
Rationale: The correct answer is Pneumonia. Pneumonia is an acute illness characterized by inflammation of the air sacs in the lungs. It comes on suddenly and typically lasts for a short duration. Treatment can help cure pneumonia. Paralysis, Alzheimer's disease, and Diabetes are chronic conditions. Paralysis is the loss of muscle function in part of the body, usually permanent. Alzheimer's disease is a progressive brain disorder leading to memory loss and cognitive decline, and it is incurable. Diabetes is a chronic condition that affects how your body turns food into energy, and it requires lifelong management. Therefore, Pneumonia is the only acute condition among the options provided.
Your patient has been diagnosed with acute bronchitis. You should expect that all of the following will be ordered EXCEPT:
- A. Increased fluid intake
- B. Cough medications
- C. Antibiotics
- D. Use of a vaporizer
Correct Answer: C
Rationale: In the management of acute bronchitis, antibiotics are not typically prescribed unless there is a confirmed bacterial infection. Acute bronchitis is usually caused by a virus, so antibiotics are not effective in treating it. The primary focus is on symptom management and supportive care. Increased fluid intake helps keep the airway moist and liquefy secretions, aiding in their removal. Cough medications can help relieve cough symptoms. The use of a vaporizer can help moisten the air, making breathing more comfortable for the patient. It is crucial to differentiate between viral and bacterial causes of respiratory infections to avoid unnecessary antibiotic use and prevent antibiotic resistance. Therefore, the correct answer is 'Antibiotics.' Increased fluid intake, cough medications, and the use of a vaporizer are commonly recommended for managing symptoms and improving comfort in patients with acute bronchitis.
The nurse is caring for a 10-year-old upon admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is
- A. Urinary output of 30 ml per hour
- B. No complaints of thirst
- C. Increased hematocrit
- D. Good skin turgor around burn
Correct Answer: A
Rationale: The correct answer is urinary output of 30 ml per hour. In a 10-year-old child, this level of urinary output is indicative of adequate fluid replacement without suggesting overload. Monitoring urinary output is crucial in assessing fluid balance. Choices B, C, and D are incorrect. No complaints of thirst do not provide a direct assessment of fluid status. Increased hematocrit is a sign of dehydration, not adequate fluid replacement. Good skin turgor around the burn is a general assessment but may not directly reflect the child's overall fluid status.
