1. Which theory reflects the view that illness is caused by an imbalance or disharmony in the forces of nature?
- A. Germ theory
- B. Naturalistic theory
- C. Magicoreligious theory
- D. Biomedical or scientific theory
Correct answer: B
Rationale: The naturalistic theory posits that illness results from an imbalance or disharmony in the forces of nature. According to this theory, maintaining a natural balance or harmony is essential to prevent illness. Conversely, germ theory and biomedical or scientific theory attribute illness to microorganisms, while magicoreligious theory attributes illness to supernatural forces such as deities or spirits. Therefore, the most appropriate theory reflecting the belief that illness arises from a disruption in natural forces is the naturalistic theory.
2. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?
- A. Often used to direct light into the sinuses
- B. Used to examine the structures of the internal ear
- C. Uses a short, broad speculum to help visualize the ear
- D. Directs light into the ear canal and onto the tympanic membrane
Correct answer: D
Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.
3. When are manual hematocrits done?
- A. to monitor anemia
- B. by using a microhematocrit tube.
- C. to measure the percentage of plasma to cells.
- D. All of the above.
Correct answer: D
Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.
4. In which of the following ways can a healthcare provider promote the sense of taste for an older adult?
- A. Mixing foods together on the dinner tray
- B. Avoiding cologne, air fresheners, or room deodorizers
- C. Encouraging the client to chew food thoroughly
- D. Discouraging the use of salt or seasonings with prepared food
Correct answer: C
Rationale: As individuals age, their sense of taste may diminish, impacting the enjoyment of eating. One effective way for a healthcare provider to promote the sense of taste for an older adult is by encouraging them to chew food thoroughly. Thorough chewing increases the contact of food with the taste buds, enhancing the chances of experiencing the flavors. Mixing foods together on the dinner tray may not necessarily enhance taste perception. Avoiding strong scents like cologne, air fresheners, or room deodorizers is more related to olfactory senses rather than taste. Discouraging the use of salt or seasonings can further diminish the taste experience for older adults who may already have reduced taste sensitivity.
5. As a charge nurse, what is your primary responsibility for a 50-year-old blind and deaf patient admitted to your floor?
- A. Inform others about the patient's deficits.
- B. Communicate patient safety concerns to your supervisor.
- C. Provide continuous updates to the patient about the social environment.
- D. Provide a secure environment for the patient.
Correct answer: D
Rationale: The primary responsibility of the charge nurse for a blind and deaf patient is to provide a secure environment. Ensuring patient safety is crucial to prevent medical errors and adverse outcomes. By creating a safe environment, the nurse can protect the patient from harm and promote well-being. Option A is incorrect as the focus should be on ensuring patient safety rather than highlighting deficits. Option B is not the primary responsibility in this scenario, as the immediate concern is the patient's safety. Option C is irrelevant and does not address the patient's primary needs, which are safety and security.
