In describing the parts of the respiratory system, the word 'septum' designates a partition in the

  • A. larynx.
  • B. nasal cavities.
  • C. pharynx.
  • D. glottis.
Correct Answer: B

Rationale: The correct answer is B: nasal cavities. The term "septum" refers to a partition or dividing wall that separates two cavities. In the context of the respiratory system, the nasal septum divides the nasal cavities into left and right sides. This separation helps to regulate airflow and also provides structural support for the nasal passages.

Other choices are incorrect because:
A: The larynx is not typically associated with a septum. It is primarily responsible for vocalization and protecting the airway.
C: The pharynx is a passageway for air and food, but it does not contain a septum dividing it into distinct sections.
D: The glottis is the space between the vocal cords in the larynx and does not have a septum separating it into parts.

A nurse is caring for a client using oxygen while in the hospital. What assessment finding indicates that outcomes for client safety with oxygen therapy are being met?

  • A. 100% of meals being eaten by the client
  • B. Intact skin behind the ears
  • C. The client understanding the need for oxygen
  • D. Unchanged weight for the past 3 days
Correct Answer: B

Rationale: The correct answer is B. Intact skin behind the ears indicates that the oxygen delivery device is fitted properly and not causing skin breakdown, ensuring client safety. A (meals being eaten) is not directly related to oxygen therapy outcomes. C (client understanding) is important but doesn't directly assess client safety with oxygen therapy. D (unchanged weight) is not a specific indicator of client safety with oxygen therapy.

A male adult patient hospitalized for treatment of a pulmonary embolism develops respiratory alkalosis. Which clinical findings commonly accompany respiratory alkalosis?

  • A. Nausea or vomiting
  • B. Abdominal pain or diarrhea
  • C. Hallucinations or tinnitus
  • D. Lightheadedness or paresthesia
Correct Answer: D

Rationale: The correct answer is D: Lightheadedness or paresthesia. Respiratory alkalosis is caused by hyperventilation, leading to decreased carbon dioxide levels and an increase in pH. This can result in symptoms such as lightheadedness (from decreased cerebral blood flow) and paresthesia (tingling sensations due to changes in calcium ionization). Choices A, B, and C are incorrect as they are not typically associated with respiratory alkalosis. Nausea, vomiting, abdominal pain, and diarrhea are more commonly seen in metabolic alkalosis, while hallucinations and tinnitus are not typical symptoms of respiratory alkalosis.

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.

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.

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.
