Tracheal respiration is found in
- A. Insects and Millipedes
- B. Scorpion and Prawn
- C. Pila and Lobuster
- D. Starfish and Sea cucumber
Correct Answer: A
Rationale: Tracheal respiration is a type of respiration system found in insects and millipedes. This system involves the use of tracheae, which are tiny tubes that deliver oxygen directly to tissues. Insects and millipedes have evolved this efficient respiratory system to support their high metabolic rates. Scorpions and prawns (Choice B), Pila and lobsters (Choice C), and starfish and sea cucumbers (Choice D) do not have tracheal respiration systems. Therefore, the correct answer is A.

A nurse is caring for a client who is scheduled to undergo a thoracentesis. Which intervention would the nurse complete prior to the procedure?
- A. Measure oxygen saturation before and after a 12-minute walk.
- B. Verify that the client understands all possible complications.
- C. Explain the procedure in detail to the client and the family.
- D. Validate that informed consent has been given by the client.
Correct Answer: D
Rationale: The correct answer is D. Validating that informed consent has been given by the client is crucial before any invasive procedure to ensure the client understands the risks, benefits, and alternatives. It also respects the client's autonomy and right to make an informed decision.
A: Measuring oxygen saturation before and after a 12-minute walk is not directly related to thoracentesis preparation.
B: Verifying the client's understanding of complications is important but not the immediate priority before the procedure.
C: Explaining the procedure to the client and family is essential but may not be the first step; ensuring informed consent comes before this step.
The emergency department (ED) manager is reviewing client charts to determine how well the staff perform when treating clients with community-acquired pneumonia. What outcome demonstrates that goals for this client type have been met?
- A. Antibiotics started before admission.
- B. Blood cultures obtained within 20 minutes.
- C. Chest x-ray obtained within 30 minutes.
- D. Pulse oximetry obtained on all clients.
Correct Answer: A
Rationale: The correct answer is A: Antibiotics started before admission. This outcome demonstrates that the staff are meeting the goal for treating clients with community-acquired pneumonia because timely administration of antibiotics is crucial in managing this condition effectively. Starting antibiotics promptly helps to reduce the spread of infection and improve patient outcomes.
Blood cultures obtained within 20 minutes (B) is important for diagnosing the specific pathogen causing pneumonia but does not directly reflect the treatment goal achievement. Chest x-ray within 30 minutes (C) is essential for diagnosis but does not indicate treatment success. Pulse oximetry on all clients (D) is important for monitoring oxygen levels but does not directly show if the treatment goal for pneumonia has been met.
The fauces connects which of the following structures to the oropharynx?
- A. nasopharynx
- B. laryngopharynx
- C. nasal cavity
- D. oral cavity
Correct Answer: D
Rationale: The correct answer is D: oral cavity. The fauces is the opening between the oral cavity and the oropharynx. It is located at the back of the mouth, connecting the oral cavity to the oropharynx. This opening allows the passage of food and liquids from the mouth to the throat during swallowing. Choices A, B, and C are incorrect because the fauces does not connect to the nasopharynx, laryngopharynx, or nasal cavity. The fauces specifically connects the oral cavity to the oropharynx, making choice D the correct answer in this context.
The lower respiratory tract is consist except
- A. Nose
- B. bronchioleg
- C. Trachea
- D. both b and c
Correct Answer: A
Rationale: The correct answer is A: Nose. The lower respiratory tract includes the trachea, bronchioles, and lungs, but not the nose. The nose is a part of the upper respiratory tract, responsible for filtering, humidifying, and warming inhaled air. The trachea and bronchioles are part of the lower respiratory tract, involved in the passage of air into the lungs for gas exchange. Therefore, the nose does not belong to the lower respiratory tract, making it the correct answer. Choices B and C (bronchioles and trachea) are incorrect as they are part of the lower respiratory tract. Choice D is incorrect because both the bronchioles and trachea are part of the lower respiratory tract.
While assessing an older adult patient, what finding indicates left-sided heart failure?
- A. Weight gain
- B. Ascites
- C. Crackles
- D. Jugular vein distention
Correct Answer: C
Rationale: The correct answer is C: Crackles. Crackles indicate left-sided heart failure due to fluid accumulation in the lungs. This occurs when the left side of the heart is unable to efficiently pump blood, leading to fluid backing up into the lungs. Weight gain (A) may be a general sign of heart failure but is not specific to left-sided failure. Ascites (B) is more indicative of right-sided heart failure, where fluid accumulates in the abdomen. Jugular vein distention (D) is a sign of right-sided heart failure, where blood backs up into the systemic circulation causing jugular vein distention.
