A home health nurse is visiting a new client who uses oxygen in the home. For which factors doesn't the nurse assess when determining if the client is using the oxygen safely?
- A. The client does not allow smoking in the house.
- B. Electrical cords are in good working order.
- C. Flammable liquids are stored in the garage.
- D. Household light bulbs are the fluorescent type.
Correct Answer: D
Rationale: The correct answer is D because household light bulbs being fluorescent type is unrelated to the safe use of oxygen. The nurse should assess factors directly related to oxygen safety, such as smoking restrictions, electrical cord condition, and proper storage of flammable materials. Fluorescent light bulbs do not pose a significant risk in relation to oxygen safety.

Which class of drugs often inhibits carbonic anhydrase and is used for certain medical conditions?
- A. Antibiotics
- B. Antihistamines
- C. Carbonic anhydrase inhibitors
- D. Antidepressants
Correct Answer: C
Rationale: The correct answer is C: Carbonic anhydrase inhibitors. These drugs inhibit the enzyme carbonic anhydrase, which plays a role in various physiological processes. They are used to treat conditions such as glaucoma, epilepsy, and altitude sickness. Antibiotics (A) target bacterial infections, antihistamines (B) relieve allergy symptoms, and antidepressants (D) treat depression, making them unrelated to carbonic anhydrase inhibition.
The collapse of lung is known as:
- A. pleurisy
- B. pleural effusion
- C. atelectasis
- D. pneumothorax
Correct Answer: C
Rationale: The correct answer is C: atelectasis. Atelectasis refers to the collapse of a lung or a part of a lung, leading to incomplete expansion of air sacs. This can be caused by various factors such as blockage of the airways or compression of the lung tissue. Pleurisy (A) is inflammation of the pleura, the lining around the lungs. Pleural effusion (B) is the accumulation of fluid in the pleural space. Pneumothorax (D) is the presence of air in the pleural space, leading to lung collapse. Atelectasis specifically describes the collapse of the lung itself, making it the correct choice.
The normal rate and depth of breathing is established by the ________ center(s).
- A. apneustic
- B. pneumotaxic
- C. DRG and VRG
- D. expiratory
Correct Answer: C
Rationale: The correct answer is C because the Dorsal Respiratory Group (DRG) and Ventral Respiratory Group (VRG) are the centers in the brainstem responsible for controlling the rate and depth of breathing. The DRG primarily regulates inspiration, while the VRG is involved in both inspiration and expiration. The apneustic and pneumotaxic centers (choices A and B) are subregions within the pons that modulate the activity of the DRG and VRG but do not establish the baseline rate and depth of breathing. The expiratory center (choice D) is responsible for controlling only the expiratory phase of breathing and is not involved in setting the normal rate and depth of breathing.
For which client(s) would you assign the nursing care to the new RN under your supervision? (Choose all that apply.)
- A. A 38-year-old client with moderate persistent asthma awaiting discharge
- B. A 63-year-old client with tracheostomy needing trach care every shift
- C. A 56-year-old client with lung cancer just returned from left lower lobectomy
- D. A 49-year-old new admission client with new diagnosis of esophageal cancer
Correct Answer: D
Rationale: The correct answer includes A and D. Assigning care for clients with moderate persistent asthma (A) and a new diagnosis of esophageal cancer (D) is appropriate for a new RN under supervision. Clients requiring tracheostomy care (B) or post-lobectomy recovery (C) involve complex care unsuitable for a new RN.
A nurse is caring for a client who received benzocaine spray prior to a recent bronchoscopy. The client presents with continuous cyanosis even with oxygen therapy. Which action should the nurse take next?
- A. Administer an albuterol treatment.
- B. Notify the Rapid Response Team.
- C. Assess the client's peripheral pulses.
- D. Obtain blood and sputum cultures.
Correct Answer: B
Rationale: The correct answer is B: Notify the Rapid Response Team. Continuous cyanosis despite oxygen therapy following benzocaine administration may indicate methemoglobinemia, a serious adverse effect. Rapid Response Team should be alerted for immediate intervention and monitoring. Albuterol treatment (A) would not address methemoglobinemia. Assessing peripheral pulses (C) may not provide immediate assistance. Obtaining blood and sputum cultures (D) is not the priority in this situation.
