A nurse is assessing a client who is recovering from a lung biopsy. Which assessment finding requires immediate action?
- A. Increased temperature
- B. Absent breath sounds
- C. Productive cough
- D. Incisional discomfort
Correct Answer: B
Rationale: The correct answer is B: Absent breath sounds. This finding could indicate a pneumothorax, a serious complication post lung biopsy requiring immediate intervention. Absent breath sounds suggest air accumulation in the pleural space, causing lung collapse. Prompt action is crucial to prevent respiratory distress. Increased temperature (A) may indicate infection but not as urgent as addressing a pneumothorax. Productive cough (C) is common post-procedure. Incisional discomfort (D) is expected and can be managed with appropriate pain relief measures.

which factors affect on exercise.
- A. body temperature
- B. smoking
- C. physical exercise
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Body temperature (A) is a factor as it affects how efficiently muscles work during exercise. Smoking (B) can negatively impact exercise performance and overall health. Physical exercise (C) is an obvious factor that directly influences exercise outcomes. Therefore, all three factors are interconnected and collectively influence an individual's exercise capacity and performance.
The experienced LPN/LVN is providing nursing care for a client with a respiratory problem. Which of the following actions are appropriate to the scope of practice for an experienced LPN/LVN? (Choose all that apply.)
- A. Auscultate breath sounds.
- B. Administer MDI (multidose inhaler) medications.
- C. Check oxygen saturation using pulse oximetry.
- D. Evaluate client's technique for using MDIs.
Correct Answer: D
Rationale: The correct answer includes A, B, and C. Auscultating breath sounds, administering MDI medications, and checking oxygen saturation are within the scope of practice for an LPN/LVN. Evaluating the client's technique (D) may require more advanced assessment skills typically performed by RNs.
The nasal conchae epithelial surface serves to:
- A. Warm and moisten inhaled air, via air turbulence.
- B. Help filter dust and insects from the inhaled air
- C. Recapture moisture from exhaled air to preserve fluid.
- D. All of the above are correct.
Correct Answer: D
Rationale: Rationale: The nasal conchae increase surface area, causing air turbulence to warm, moisten, and filter inhaled air. This helps in preventing respiratory issues. Choice A is correct as it explains the primary function of the conchae. Choice B is incorrect as the primary function is not filtering. Choice C is incorrect as the conchae primarily warm and moisten inhaled air rather than recapture moisture from exhaled air. Overall, choice D is correct as it encompasses all the functions of the nasal conchae.
The nurse is preparing a presentation that highlights the benefits of annual influenza vaccination. The nurse correctly targets which groups Except?
- A. Parents of children 3 to 6 months of age.
- B. Diabetics who are over 50 years old.
- C. Pregnant women.
- D. Home health aides.
Correct Answer: A
Rationale: The correct answer is A because children aged 3 to 6 months are too young to receive the influenza vaccine. They are not recommended for vaccination until they reach 6 months of age. Choice B is correct as older diabetics are at higher risk for complications from the flu. Choice C is correct as pregnant women are a high-risk group for flu-related complications. Choice D is correct as home health aides are in close contact with vulnerable populations.
Which of the following sinuses are located on either side of the nose?
- A. Ethmoidal sinuses
- B. Frontal sinuses
- C. Maxillary sinuses
- D. Sphenoidal sinuses
Correct Answer: C
Rationale: The correct answer is C. The maxillary sinuses are paired cavities located on either side of the nose, beneath the orbits. Ethmoidal sinuses (A) are smaller and located between the eyes. Frontal sinuses (B) are above the eyebrows. Sphenoidal sinuses (D) are deeper within the skull, behind the nasal cavity.
