Nokea
All of the following are unpaired cartilage of larynx except
- A. epiglottis
- B. cricoid
- C. Thyroid
- D. cuneiform
Correct Answer: D
Rationale: The correct answer is D: cuneiform. The cuneiform cartilages are paired cartilages, not unpaired. The epiglottis, cricoid, and thyroid cartilages are unpaired cartilages of the larynx. The epiglottis functions in covering the larynx during swallowing, the cricoid provides support for the larynx, and the thyroid cartilage forms the "Adam's apple." The cuneiform cartilages, on the other hand, are small paired cartilages located within the aryepiglottic folds. They help maintain the shape and stiffness of these folds, assisting in vocal cord function.

A 19-year-old client comes to the emergency department with acute asthma. His respiratory rate is 44 breaths/minute, and he appears in acute respiratory distress. Which of the following actions should be taken first?
- A. Take a full medical history.
- B. Give a bronchodilator by nebulizer.
- C. Apply a cardiac monitor to the client.
- D. Provide emotional support to the client.
Correct Answer: B
Rationale: The correct answer is B: Give a bronchodilator by nebulizer. In acute asthma, the priority is to relieve respiratory distress by opening up the airways. Bronchodilators help to quickly alleviate bronchospasm and improve airflow. This action should be taken first to improve the client's breathing. Taking a full medical history (A) can be important but is not the priority in this acute situation. Applying a cardiac monitor (C) is not the immediate concern in acute asthma. Providing emotional support (D) is also important but should come after ensuring the client's respiratory distress is managed.
The pneumotaxic center of the pons
- A. sets the at-rest respiratory pattern
- B. prolongs inspiration
- C. modifies the rate and depth of breathing
- D. suppresses the expiratory center in the medulla
Correct Answer: C
Rationale: The correct answer is C because the pneumotaxic center in the pons modifies the rate and depth of breathing by sending inhibitory signals to the dorsal respiratory group in the medulla, which controls inspiration and expiration. It does not set the at-rest respiratory pattern like option A, prolong inspiration like option B, or suppress the expiratory center in the medulla like option D. This center plays a crucial role in fine-tuning breathing patterns to maintain appropriate oxygen levels in the body.
The nurse is caring for a patient who has been scheduled for a bronchoscopy. How should the nurse prepare the patient for this procedure?
- A. Administer a bolus of IV fluids.
- B. Arrange for the insertion of a peripherally inserted central catheter.
- C. Administer nebulized bronchodilators every 2 hours until the test.
- D. Withhold food and fluids for several hours before the test.
Correct Answer: D
Rationale: The correct answer is D because withholding food and fluids for several hours before a bronchoscopy is important to prevent aspiration during the procedure. When the patient is sedated for the bronchoscopy, there is an increased risk of vomiting, and having an empty stomach reduces this risk. Administering IV fluids (choice A) is not necessary unless clinically indicated. Inserting a peripherally inserted central catheter (choice B) is not typically required for a bronchoscopy. Administering nebulized bronchodilators (choice C) may not be needed for all patients and should be based on the individual's respiratory condition.
You are the team leader RN working with a student nurse. The student nurse is to teach the client how to use a multidose inhaler without a spacer. Put the steps that the student nurse should teach the client in correct order.
- A. Remove the inhaler cap and shake the inhaler.
- B. Tilt your head back and breathe out fully.
- C. Press down firmly on the canister and breathe deeply through your mouth.
- D. Wait at least 1 minute between puffs.
Correct Answer: D
Rationale: The correct order is: A (remove cap and shake), B (tilt head back and breathe out), C (press down and breathe in), D (wait between puffs). This sequence ensures proper inhaler technique.
What is the best action for the nurse to do?
- A. a. Leave the patient alone to rest in a quiet, calm environment.
- B. b. Stay with the patient and encourage slow, pursed lip breathing.
- C. c. Reassure the patient that the attack can be controlled with treatment.
- D. Let the patient know that frequent monitoring is being done using measurement of vital signs and SpO. 2
Correct Answer: B
Rationale: The best action for the nurse to do is to stay with the patient and encourage slow, pursed lip breathing. This helps the patient focus on their breathing and can help alleviate the asthma attack symptoms.
