1. What is the transparent membrane that focuses the light entering the eyes onto the retina?
- A. Lens
- B. Sclera
- C. Cornea
- D. Pupils
Correct answer: A
Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.
2. A nurse is providing teaching about gastrostomy tube feedings to the parents of a school-age child. Which of the following instructions should the nurse give?
- A. Administer the feeding over 30 minutes
- B. Place the child in a supine position after the feeding
- C. Change the feeding bag and tubing every 3 days
- D. Warm the formula in a warm water bath before administration
Correct answer: B
Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.
3. For a rectal examination, the patient can be directed to assume which of the following positions?
- A. Genupectoral
- B. Sims
- C. Horizontal recumbent
- D. All of the above
Correct answer: B
Rationale: The correct position for a rectal examination is the Sims position, where the patient lies on their left side with the upper knee flexed. This position allows for easy access and visualization of the rectal area for examination.
4. The nurse observes that Mr. Adams begins to have increased difficulty breathing. She elevates the head of the bed to the high Fowler position, which decreases his respiratory distress. The nurse documents this breathing as:
- A. Tachypnea
- B. Eupnea
- C. Orthopnea
- D. Hyperventilation
Correct answer: C
Rationale: Orthopnea is a condition where a person experiences difficulty breathing when lying flat but finds relief when sitting up or standing. Elevating the head of the bed to the high Fowler position helps alleviate this symptom. Tachypnea refers to rapid breathing, eupnea is normal breathing, and hyperventilation is breathing excessively fast or deep.
5. Which of the following is not a cause of tachycardia?
- A. Fever
- B. Exercise
- C. Sympathetic nervous system stimulation
- D. Parasympathetic nervous system stimulation
Correct answer: D
Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.
