1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. Which of the following is the correct abbreviation for drops?

• A. Gtt.
• B. Gtts.
• C. Dp.
• D. Dr.

Correct answer: A

Rationale: The correct abbreviation for drops in medical terminology is 'Gtt.' It is derived from the Latin word 'guttae,' meaning drops. The abbreviation 'Gtts.' (Choice B) is incorrect as it adds an unnecessary 's.' Choices C and D, 'Dp.' and 'Dr.,' are not standard abbreviations for drops in medical contexts, making them incorrect.

3. A healthcare professional is preparing to measure an infant's temperature. Which of the following actions should the healthcare professional take?

• A. Place the tip of the thermometer under the center of the infant's axilla
• B. Pull the pinna of the infant's ear forward before inserting the probe
• C. Insert the probe 3.8 cm (1.5in) into the infant's rectum
• D. Insert the thermometer in front of the infant's tongue

Correct answer: A

Rationale: When measuring an infant's temperature, the most appropriate and non-invasive method is to place the tip of the thermometer under the center of the infant's axilla (armpit). This method is safe, quick, and comfortable for the infant. Inserting the probe into the rectum is invasive and not recommended for routine temperature measurement in infants. Inserting the thermometer in front of the infant's tongue is not a reliable method for measuring temperature. Pulling the pinna of the ear forward is a technique used for adults, not infants.

4. A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?

• A. Your urine can turn a dark orange.
• B. Watch for a change in the sclera of your eyes.
• C. Watch for any changes in vision.
• D. Take vitamin B6 daily.

Correct answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

5. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

• A. Confusion
• B. Pale skin
• C. Bradycardia
• D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.
