Review Multiple Choice Questions and Answers on Respiratory System related questions and content

A nurse cares for a client who had a bronchoscopy 2 hours ago. The client asks for a drink of water. What action would the nurse take next?

  • A. Call the primary health care provider and request food and water for the client.
  • B. Provide the client with ice chips instead of a drink of water.
  • C. Assess the client's gag reflex before giving any food or water.
  • D. Let the client have a small sip to see whether he or she can swallow.
Correct Answer: C

Rationale: The correct answer is C: Assess the client's gag reflex before giving any food or water. After a bronchoscopy, the client's gag reflex may be compromised, increasing the risk of aspiration. Assessing the gag reflex is crucial to ensure the client can safely swallow without the risk of choking or aspirating. This step is essential before providing any food or water to prevent potential complications.

Incorrect Choices:
A: Calling the primary health care provider for food and water is unnecessary as the nurse can make this decision based on assessment.
B: Providing ice chips instead of water does not address the need for assessing the gag reflex before giving any form of intake.
D: Letting the client have a small sip without assessing the gag reflex first can pose a risk of aspiration if the reflex is impaired.

Cloacal respiration is found in

  • A. Snake
  • B. Turtle and Tortoise
  • C. Crocodile
  • D. Frog
Correct Answer: B

Rationale: Cloacal respiration is found in turtles and tortoises. These reptiles can absorb oxygen through their cloaca, a multi-functional opening used for excretion and reproduction. Turtles and tortoises lack specialized respiratory organs like lungs, and thus utilize cloacal respiration as an additional means of obtaining oxygen. Snakes (Option A) primarily rely on lung respiration. Crocodiles (Option C) have well-developed lungs for breathing. Frogs (Option D) respire through their skin and lungs but do not utilize cloacal respiration like turtles and tortoises. Therefore, the correct answer is B, as it is the only species listed that exhibits cloacal respiration.

Exchange across a membrane requires

  • A. moisture.
  • B. transport proteins
  • C. pressure gradients.
  • D. all of the above
Correct Answer: D

Rationale: Exchange across a membrane involves the movement of molecules or ions. Moisture (A) helps facilitate this movement by dissolving solutes. Transport proteins (B) are essential for facilitating the movement of specific molecules across the membrane. Pressure gradients (C) can drive the movement of substances across the membrane. Therefore, the correct answer is D, as all these factors play a crucial role in facilitating exchange across a membrane. Moisture alone is not sufficient for exchange, transport proteins are necessary for specific molecule transport, and pressure gradients can aid in driving the movement of substances.

Identify the inconsistent value at sea level

  • A. Alveolar pCO2 = 40mmHg
  • B. Alveolar pO2 = 100mmHg
  • C. Alveolar PH2O = 47mmHg
  • D. pO2 of inspired air = 130mmHg
Correct Answer: D

Rationale: The correct answer is D because at sea level, the pO2 of inspired air is around 159mmHg, not 130mmHg. This is due to the partial pressure of oxygen being higher at sea level. Alveolar pCO2, pO2, and PH2O values are consistent with normal values at sea level. Therefore, D is the inconsistent value.

The nurse is completing a patient's health history with regard to potential risk factors for lung disease. What interview question addresses the most significant risk factor for respiratory diseases?

  • A. Have you ever been employed in a factory, smelter, or mill?
  • B. Does anyone in your family have any form of lung disease?
  • C. Do you currently smoke, or have you ever smoked?
  • D. Have you ever lived in an area that has high levels of air pollution?
Correct Answer: C

Rationale: The correct answer is C: "Do you currently smoke, or have you ever smoked?" Smoking is the most significant risk factor for respiratory diseases, including lung cancer, chronic obstructive pulmonary disease, and emphysema. Asking about smoking history is crucial in assessing lung disease risk.

Rationale:
1. Smoking is the leading cause of preventable death worldwide.
2. Smoking damages the lungs and increases the risk of developing various respiratory conditions.
3. Current and past smoking status helps determine the level of risk for lung disease.
4. Tobacco smoke contains harmful chemicals that can lead to lung damage over time.

Summary:
A: Occupational exposure is a risk factor, but smoking has a stronger association with respiratory diseases.
B: Family history is relevant but not as directly linked to individual behavior and risk as smoking.
D: Air pollution can contribute to lung issues, but personal smoking history has a more direct impact on lung health.

The cessation of smoking

  • A. can reduce the risk of stillbirth
  • B. reduces the chances of cancer
  • C. reduces the chances of coronary disease
  • D. all of the above
Correct Answer: D

Rationale: The correct answer is D, all of the above. Cessation of smoking reduces the risk of stillbirth by improving fetal health. It also reduces the chances of cancer by decreasing exposure to carcinogens. Additionally, quitting smoking decreases the risk of coronary disease by improving heart health. Therefore, all the choices are correct as they highlight different positive outcomes of quitting smoking.
