A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?

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.

Correct Answer: B

Rationale: The 1981 Philippine Nursing Code of Ethics mandates national organization membership (PNA) e.g., ensuring accountability. R.A. 877 (old law), R.A. 7164 (1991 law), and PNA memos differ. This reflects nursing's collective duty, reinforcing unity and ethical standards in practice.

Correct Answer: A

Rationale: Acupuncture with meds is complementary therapy (A) with conventional, per definition. Alternative (B) replaces, touch (C) hands, promotion (D) well-being not combo-specific. A fits integrated use, making it correct.

Correct Answer: B

Rationale: Taking Glucotrol XL with breakfast aligns with its peak action to control post-meal glucose in diabetes bedtime, pre-lunch, or post-dinner mistime it. Nurses teach this, ensuring glycemic control, vital for managing type 2 diabetes effectively.

Correct Answer: A

Rationale: Supine with pillows under knees and head relaxes abdominal muscles, aiding examination, unlike semi-Fowler's, sitting, or arms-up positions. Nurses use this for effective assessment.

Correct Answer: D

Rationale: Aspirating urine from the tubing port with a sterile syringe is the appropriate action for obtaining a sterile urine specimen from an indwelling catheter. This maintains the closed system's integrity, minimizing infection risk by avoiding exposure to external contaminants. The port is designed for sterile sampling, ensuring the specimen reflects bladder contents accurately for testing. Using sterile gloves aids asepsis but isn't the complete action; it supports the procedure, not defines it. Opening the drainage bag introduces bacteria, risking contamination and infection. Disconnecting the catheter breaks the sterile circuit, increasing urinary tract infection likelihood contrary to best practice. Aspiration via the port, paired with aseptic technique, upholds infection control standards, ensuring patient safety and reliable diagnostic results, making it the optimal nursing action.

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.

Correct Answer: B

Rationale: Clinitest detects sugar e.g., glucose in diabetes via tablet reaction, unlike acetic (protein), PKU tests (phenylketones), or bilirubin assays. Nurses use e.g., bedside for quick checks, per diagnostics.

Correct Answer: C

Rationale: The nurse ensures the patient eats, while the physician handles test orders and instructions.
