A client has been hospitalized with tuberculosis (TB). The client's spouse is fearful of entering the room where the client is in isolation and refuses to visit. What action by the nurse is best?
- A. Ask the spouse to explain the fear of visiting in further detail.
- B. Inform the spouse that the precautions are meant to keep other clients safe.
- C. Show the spouse how to follow the Isolation Precautions to avoid illness.
- D. Tell the spouse that he or she has already been exposed, so it's safe to visit.
Correct Answer: A
Rationale: The correct answer is A: Ask the spouse to explain the fear of visiting in further detail. By asking the spouse to explain their fear, the nurse can address and alleviate specific concerns, providing tailored support. This approach promotes open communication and understanding, which may help the spouse feel more comfortable visiting.
B: Informing the spouse about precautions may not address the underlying fear and could come across as dismissive.
C: Showing how to follow precautions does not directly address the spouse's fear and may not be sufficient to alleviate concerns.
D: Telling the spouse they have already been exposed may not address their fear and could potentially increase anxiety.

After inspiration commences the:
- A. Intrapleural pressure and intrapulmonary P both fall
- B. Intrapleural pressure falls and intrapulmonary P rises
- C. Intrapleural pressure falls and venous return decreases
- D. Intrapulmonary pressure rises and volume of the alveoli is momentarily unchanged
Correct Answer: A
Rationale: After inspiration commences, the diaphragm contracts and the thoracic cavity expands. This leads to a decrease in intrapleural pressure, allowing the lungs to expand. Simultaneously, intrapulmonary pressure decreases, creating a pressure gradient for air to flow into the lungs. Choice A is correct because both intrapleural pressure and intrapulmonary pressure fall during inspiration.
Choice B is incorrect because intrapulmonary pressure actually decreases during inspiration, not rises. Choice C is incorrect because intrapleural pressure falling does not directly correlate with a decrease in venous return. Choice D is incorrect because during inspiration, the volume of the alveoli increases as the lungs expand, causing intrapulmonary pressure to decrease.
A 62-yr-old client who has no history of hypertension or other health problems suddenly develops a blood pressure (BP) of 198/110 mm Hg. After reconfirming the BP.What is most appropriate for the nurse to tell the client
- A. BP recheck should be scheduled in a few weeks.
- B. dietary sodium and fat content should be decreased.
- C. diagnosis, treatment, and monitoring will be needed.
- D. there is danger of a stroke, requiring hospitalization.
Correct Answer: C
Rationale: The correct answer is C because a sudden spike in blood pressure to 198/110 mm Hg is considered hypertensive crisis requiring immediate medical attention. The nurse should inform the client that diagnosis, treatment, and monitoring are necessary to address the high blood pressure. This is important to prevent serious complications like stroke or heart attack.
Option A is incorrect because waiting a few weeks for a BP recheck could be dangerous in this scenario. Option B is also incorrect as simple dietary changes may not be sufficient to address such high blood pressure levels. Option D is incorrect as hospitalization may or may not be required based on the assessment and treatment plan determined by the healthcare provider.
The process of respiration is concerned with
- A. Intake O2
- B. Liberation of O2
- C. Liberation of CO2
- D. liberation of energy
Correct Answer: D
Rationale: The correct answer is D: liberation of energy. Respiration involves the conversion of glucose into ATP, releasing energy that cells can use for various functions. Oxygen is taken in during respiration (A), not liberated (B). Carbon dioxide is released (C) as a byproduct of respiration, not liberated. Option D is correct as it accurately captures the primary purpose of respiration.
A female client must take streptomycin for tuberculosis. Before therapy begins, the nurse should instruct the client to notify the physician if a health concern occurs?
- A. Impaired color discrimination
- B. Increased urinary frequency
- C. Decreased hearing acuity
- D. Increased appetite
Correct Answer: C
Rationale: The correct answer is C: Decreased hearing acuity. Streptomycin is known to cause ototoxicity, which can lead to decreased hearing acuity. Therefore, the nurse should instruct the client to notify the physician if any changes in hearing occur to prevent permanent hearing loss. Impaired color discrimination (A) and increased appetite (D) are not commonly associated with streptomycin use. Increased urinary frequency (B) is not a typical side effect of streptomycin and would not require immediate physician notification.
Stimulation of the apneustic center would result in
- A. increased respiratory rate
- B. more intense inhalation
- C. a shorter respiratory cycle
- D. less activity in the DRG center
Correct Answer: B
Rationale: The correct answer is B: more intense inhalation. The apneustic center is responsible for prolonging inhalation by stimulating the inspiratory neurons in the medulla oblongata. When the apneustic center is stimulated, it disrupts the normal breathing pattern, causing a prolonged and more intense inhalation. This results in deeper and more forceful breaths.
Incorrect choices:
A: increased respiratory rate - Stimulation of the apneustic center would not lead to an increased respiratory rate, but rather to changes in the depth and intensity of inhalation.
C: a shorter respiratory cycle - The apneustic center's stimulation does not lead to a shorter respiratory cycle, but rather to a prolonged inhalation phase.
D: less activity in the DRG center - The dorsal respiratory group (DRG) is responsible for initiating inspiration, and the apneustic center does not affect its activity.
