Which of the following factors may alter the level of consciousness in a patient?
- A. Alcohol
- B. Electrolytes
- C. Infection
- D. All of the above may cause altered level of consciousness
Correct Answer: D
Rationale: Various factors can lead to altered levels of consciousness in a patient. Alcohol consumption can depress the central nervous system and cause changes in consciousness. Electrolyte imbalances, such as hyponatremia or hypernatremia, can disrupt brain function and affect consciousness. Infections, especially those affecting the brain like encephalitis, can also lead to alterations in consciousness. Therefore, all of the choices provided - Alcohol, Electrolytes, and Infection - can potentially cause changes in the level of consciousness. Remember the acronym AEIOU-TIPPS to recall common causes of decreased level of consciousness, including Alcohol, Electrolytes, and Infection, among others.

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.
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.
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.
A 3-year-old child is seen in the health care clinic, and a diagnosis of encopresis is made. The nurse expects to provide teaching about which client problem?
- A. Odor
- B. Nausea
- C. Malaise
- D. Diarrhea
Correct Answer: A
Rationale: Encopresis is the repeated voluntary or involuntary passage of feces of normal or near-normal consistency in places not appropriate for that purpose according to the individual's own sociocultural setting. Signs of encopresis include evidence of soiled clothing, scratching or rubbing the anal area due to irritation, fecal odor without apparent awareness by the child, and social withdrawal. Teaching about odor is essential to address the issue of encopresis. Choices B, C, and D are incorrect because encopresis is not typically associated with nausea, malaise, or diarrhea. Therefore, teaching about these symptoms would not be relevant in the context of encopresis.
What is the cause of meningitis that is fatal in half of the infected patients?
- A. Virus
- B. Bacteria
- C. Fungus
- D. Noninfectious agent
Correct Answer: B
Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
