Nokea
A nurse is assessing clients on a rehabilitation unit. Which client is not at risk for airway loss related to aspirated oral and nasopharyngeal secretions?
- A. A 24 year old with a traumatic brain injury
- B. A 36 year old who fractured his left femur
- C. A 58 year old getting radiation therapy
- D. A 66 year old who is a quadriplegic
Correct Answer: B
Rationale: The correct answer is B, a 36-year-old who fractured his left femur. This client is not at risk for airway loss related to aspirated secretions because a femur fracture does not directly impact the airway or swallowing function. Traumatic brain injury (choice A), radiation therapy (choice C), and quadriplegia (choice D) can all impair the client's ability to protect their airway and increase the risk of aspirating secretions. Therefore, these clients are at higher risk compared to the client with a femur fracture.

The nurse is caring for a patient with advanced emphysema. Which sign isn't manifestations of this disorder?
- A. Productive cough
- B. Dyspnea
- C. Barrel chest
- D. Wheezing
Correct Answer: D
Rationale: The correct answer is D: Wheezing. Emphysema is characterized by destruction of lung tissue, leading to air trapping and decreased airflow. Wheezing is typically associated with asthma or bronchitis, not emphysema. A: Productive cough is common in emphysema due to increased mucus production. B: Dyspnea (shortness of breath) is a hallmark symptom of emphysema due to impaired gas exchange. C: Barrel chest is a physical finding in emphysema caused by hyperinflation of the lungs.
during rest state normal breathing called
- A. Breathing
- B. diaphragmatic
- C. Diaphragmatic breathing
- D. non
Correct Answer: C
Rationale: The correct answer is C: Diaphragmatic breathing. During rest, normal breathing involves the diaphragm contracting and moving downward to draw air into the lungs. This type of breathing is known as diaphragmatic breathing. Choice A (Breathing) is too broad and does not specify the involvement of the diaphragm. Choice B (Diaphragmatic) does not fully describe the process of breathing during rest. Choice D (Non) is incorrect as it does not provide any information related to the breathing process during rest state. Therefore, C is the most accurate choice as it specifically identifies the type of breathing that occurs during rest.
Which information from a client helps the nurse confirm the previous diagnosis of chronic stable angina?
- A. The pain wakes me up at night.
- B. The pain is level 3 to 5 (0 to 10 scale).
- C. The pain has gotten worse over the last week.
- D. The pain goes away after I stop jogging.
Correct Answer: D
Rationale: The correct answer is D because chronic stable angina is characterized by chest pain or discomfort that is triggered by physical exertion or emotional stress and relieved by rest or medication. Therefore, the fact that the pain goes away after stopping jogging aligns with the typical pattern of chronic stable angina.
A: The pain waking the client up at night is more indicative of unstable angina or a heart attack.
B: The level of pain on a scale does not provide conclusive evidence of chronic stable angina.
C: Pain worsening over time may suggest unstable angina or a heart attack rather than chronic stable angina.
cochlea's have how many fluid filled chamber?
- A. 1
- B. 2
- C. 3
- D. 4
Correct Answer: C
Rationale: The cochlea has 3 fluid-filled chambers: the scala vestibuli, scala media, and scala tympani. These chambers are essential for hearing as they contain different fluids (perilymph and endolymph) that help transmit sound vibrations. Choice A (1 chamber) is incorrect as the cochlea has multiple distinct chambers. Choice B (2 chambers) is incorrect as it does not accurately reflect the anatomical structure of the cochlea. Choice D (4 chambers) is incorrect as the cochlea typically consists of 3 chambers, not 4. Therefore, the correct answer is C (3 chambers) based on the accurate anatomical structure of the cochlea.
Asthma is caused due to
- A. Infection of trachea
- B. Infection of lungs
- C. Bleeding into pleural cavity
- D. Spasm in bronchial muscles
Correct Answer: D
Rationale: The correct answer is D: Spasm in bronchial muscles. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing. Bronchial muscles in the airways undergo spasms, causing constriction and making it hard to breathe. Infection of the trachea (A) or lungs (B) may lead to respiratory symptoms but is not the primary cause of asthma. Bleeding into the pleural cavity (C) is unrelated to the pathophysiology of asthma. Therefore, the correct answer is D as it directly correlates with the underlying mechanism of asthma.
