The healthcare provider is reviewing theories of illness. The germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions, is a basic belief of which theory of illness?
- A. Holistic
- B. Biomedical
- C. Naturalistic
- D. Magicoreligious
Correct Answer: B
Rationale: The correct answer is B: Biomedical. Among the biomedical explanations for disease is the germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions. The naturalistic or holistic perspective holds that the forces of nature must be kept in natural balance. The magicoreligious perspective holds that supernatural forces dominate and cause illness or health. Therefore, options A, C, and D are incorrect as they do not align with the germ theory explanation provided in the question.

Which of the following descriptions best describes the function of the thyroid gland?
- A. The thyroid gland converts glucose into glycogen
- B. The thyroid gland secretes cortisol during times of stress
- C. The thyroid gland regulates body metabolism
- D. The thyroid gland affects skin pigmentation
Correct Answer: C
Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.
An experienced healthcare professional instructs a new colleague on caring for a patient with dyspnea due to a pulmonary fungal infection. Which action by the new colleague indicates a need for further teaching?
- A. Listening to the patient's lung sounds several times during the shift
- B. Placing the patient in droplet precautions and in a private hospital room
- C. Increasing the oxygen flow rate to maintain oxygen saturation above 90%
- D. Monitoring the patient's serology results to identify the specific infecting organism
Correct Answer: B
Rationale: The correct answer is placing the patient in droplet precautions and in a private hospital room. Fungal infections are not transmitted from person to person, so isolation procedures like droplet precautions are unnecessary. Listening to the patient's lung sounds, increasing the oxygen flow rate, and monitoring serology results are all appropriate actions in caring for a patient with dyspnea caused by a pulmonary fungal infection.
A patient has suddenly developed shortness of breath and appears to be in significant respiratory distress. After calling the physician and placing the patient on oxygen, which of these actions is the best for the nurse to take when further assessing the patient?
- A. Count the patient's respirations.
- B. Bilaterally percuss the thorax, noting any differences in percussion tones.
- C. Call for a chest x-ray and wait for the results before beginning an assessment.
- D. Inspect the thorax for any new masses and bleeding associated with respirations.
Correct Answer: B
Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.
What action by the nurse is appropriate when examining a 16-year-old male teenager?
- A. Discuss health teaching with the teenager to promote wellness.
- B. Ask the parent to step out of the room during the history and physical examination to respect the teenager's privacy.
- C. Use age-appropriate communication when speaking to the teenager to ensure understanding.
- D. Provide feedback that his body is developing normally and discuss the wide variation among teenagers on the rate of growth and development.
Correct Answer: D
Rationale: During the examination of a 16-year-old male teenager, it is essential to provide feedback that his body is developing normally and to discuss the wide variation among teenagers regarding growth and development. This reassures the teenager about his health status and addresses any concerns about physical development. It is important to recognize that adolescents are very conscious of their body image and often compare themselves to their peers, hence the need for such feedback. Asking the parent to step out of the room respects the teenager's privacy and promotes open communication between the nurse and the teenager. Using age-appropriate communication is crucial to ensure that the teenager understands the information provided. Asking the parent to stay in the room may not be ideal as it can inhibit open discussion, and talking to the teenager as if they were a younger child is inappropriate and may undermine their autonomy and understanding.
Which action is appropriate for the nurse to delegate to unlicensed assistive personnel (UAP)?
- A. Listen to a patient's lung sounds for wheezes or rhonchi.
- B. Label specimens obtained during percutaneous lung biopsy.
- C. Instruct a patient about how to use home spirometry testing.
- D. Measure induration at the site of a patient's intradermal skin test.
Correct Answer: B
Rationale: Labeling specimens obtained during a percutaneous lung biopsy is a task that can be appropriately delegated to unlicensed assistive personnel (UAP) as it does not require nursing judgment. UAP can perform this task safely under the supervision of a nurse. Listening to a patient's lung sounds for wheezes or rhonchi, instructing a patient about how to use home spirometry testing, and measuring induration at the site of a patient's intradermal skin test all require nursing judgment and interpretation of findings. These tasks should be performed by licensed nursing personnel to ensure accurate assessment and appropriate intervention.
