A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?
- A. 1-2 liters per minute
- B. 4-6 liters per minute
- C. 8-10 liters per minute
- D. 12-15 liters per minute
Correct Answer: B
Rationale: A flow rate of 4-6 liters per minute (B) is appropriate for nasal cannula oxygen therapy, delivering 36-44% oxygen, suitable for moderate hypoxemia. 1-2 L/min (A) (24-28%) suits mild cases or rest. 8-10 L/min (C) exceeds nasal cannula capacity, causing discomfort. 12-15 L/min (D) is for high-flow systems, not cannulas. This range balances efficacy and tolerance, per respiratory care standards, ensuring adequate oxygenation without nasal irritation.

The country where SHUSHURUTU originated
- A. China
- B. Egypt
- C. India
- D. Babylonia
Correct Answer: C
Rationale: Shushurutu, an ancient surgical text from India (circa 1000 BCE), details procedures like cataract surgery, rooted in Ayurveda.

A client attached to mechanical ventilation suddenly becomes restless and pulls out the tracheostomy tube. Which is the nurse's priority intervention?
- A. Prepare for reintubation.
- B. Call the health care provider.
- C. Call the rapid response team.
- D. Check the client for spontaneous breathing.
Correct Answer: D
Rationale: If a tracheostomy tube is dislodged, checking for spontaneous breathing (D) is the priority to assess airway patency and oxygenation need. Preparing for reintubation (A) or calling teams (B, C) follows. D is correct. Rationale: Assessing breathing determines if immediate reinsertion or oxygenation is urgent, guiding next steps per respiratory emergency standards, ensuring patient stability first.
A patient develops red eyes 2 days after an episode of malaria probable cause is:
- A. Conjunctivitis
- B. Anterior uveitis
- C. Viral keratitis
- D. Endophthalmitis
Correct Answer: B
Rationale: Red eyes post-malaria suggest an ocular complication. Conjunctivitis (choice A) causes redness but isn't typically linked to malaria unless secondary infection occurs. Anterior uveitis (choice B), inflammation of the iris and ciliary body, is a rare but documented malaria sequel, possibly from immune response or parasite-related damage, presenting with redness, pain, and photophobia. Viral keratitis (choice C) affects the cornea and is unrelated to malaria. Endophthalmitis (choice D), a severe intraocular infection, is unlikely without trauma or surgery. B is correct, as anterior uveitis aligns with malaria's systemic inflammatory effects. Nurses should assess eye symptoms, refer to ophthalmology, and manage pain, preventing vision loss in such cases.
