1. Which of the following is responsible for laws mandating the reporting of certain infections and diseases?
- A. Centers for Disease Control and Prevention (CDC)
- B. individual state laws
- C. National Institutes of Health (NIH)
- D. Health and Human Services (HHS)
Correct answer: B
Rationale: Individual state laws mandate the reporting of infectious diseases. The list of reportable diseases varies from state to state and is overseen by state health departments. While the CDC plays a significant role in disease surveillance, reporting infectious diseases is primarily governed by individual state laws. The CDC's role is to provide support, guidance, and expertise to state health departments. The National Institutes of Health (NIH) primarily focus on biomedical and health-related research, not on mandating disease reporting. Health and Human Services (HHS) is a federal department that oversees various agencies, but the responsibility for mandating disease reporting lies with individual states.
2. What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1�F at 4 a.m.?
- A. delta sleep
- B. slow brain waves
- C. pneumonia
- D. circadian rhythm
Correct answer: D
Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1�F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
3. Why might breast implants interfere with mammography?
- A. They might cause additional discomfort.
- B. They are contraindications to mammography.
- C. They are likely to be dislodged.
- D. They might prevent detection of masses.
Correct answer: D
Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.
4. When a client is having a seizure and their blood oxygen saturation drops from 92% to 82%, what should the nurse do first?
- A. Open the airway.
- B. Administer oxygen.
- C. Suction the client.
- D. Check for breathing.
Correct answer: A
Rationale: When a client is experiencing a seizure and their blood oxygen saturation drops, the priority action for the nurse is to open the airway. Ensuring a clear airway is essential to maintain oxygenation during a seizure episode. Administering oxygen may be necessary but is secondary to ensuring a patent airway. Suctioning the client should only be done if there is an airway obstruction. Checking for breathing is important, but opening the airway takes precedence to support ventilation and oxygenation.
5. Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?
- A. epilepsy
- B. Parkinson's
- C. multiple sclerosis
- D. Huntington's chorea
Correct answer: D
Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.
