1. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?
- A. Removal of an ingrown toenail
- B. Tooth extraction
- C. Abdominal surgery
- D. Cataract surgery
Correct answer: C
Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.
2. The nurse discovers welts on the back of a Vietnamese child during a home health visit. The child's mother says she has rubbed the edge of a coin on her child's oiled skin. The nurse should recognize this as what?
- A. Child abuse
- B. Cultural practice to rid the body of disease
- C. Cultural practice to treat enuresis or temper tantrums
- D. Child discipline measure common in the Vietnamese culture
Correct answer: B
Rationale: This practice, known as "coining," is a cultural method believed to rid the body of illness and is not indicative of child abuse.
3. A nurse is providing teaching to a client who has a new prescription for levothyroxine. Which of the following statements should the nurse include?
- A. Take this medication with food to prevent gastrointestinal upset.
- B. Take this medication in the morning to prevent insomnia.
- C. You may experience weight gain while taking this medication.
- D. You should avoid eating foods that contain iodine.
Correct answer: B
Rationale: The correct answer is B. Instructing the client to take levothyroxine in the morning is important to prevent insomnia, a common side effect of this medication. Choice A is incorrect as levothyroxine should be taken on an empty stomach. Choice C is inaccurate because weight loss, not weight gain, is a potential side effect of levothyroxine. Choice D is not necessary as clients do not need to avoid foods containing iodine while taking levothyroxine.
4. The mother of a 6-month-old infant has returned to work and is expressing breast milk to be frozen. She asks for directions on how to safely thaw the breast milk in the microwave. What should the nurse recommend?
- A. Heat only 10 oz or more.
- B. Do not thaw or heat breast milk in a microwave oven.
- C. Always leave the bottle top uncovered to allow heat to escape.
- D. Shake the bottle vigorously for at least 30 seconds after heating.
Correct answer: B
Rationale: Thawing or heating breast milk in a microwave is not recommended because it can create hot spots that may burn the infant and destroy essential nutrients.
5. What is the term for a condition where the lung collapses due to air leaking into the space between the lung and the chest wall?
- A. Pneumothorax
- B. Pleural effusion
- C. Atelectasis
- D. Pulmonary fibrosis
Correct answer: A
Rationale: Pneumothorax is the correct answer for this question. Pneumothorax is the collapse of a lung caused by the presence of air in the pleural space between the lung and chest wall. This condition can lead to chest pain, shortness of breath, and may require emergency treatment such as chest tube insertion to remove the air. Pleural effusion is the accumulation of fluid in the pleural space, not air. Atelectasis is the collapse or closure of a lung resulting in reduced or absent gas exchange. Pulmonary fibrosis is a condition characterized by scarring and thickening of lung tissue, not related to air leaking into the pleural space.
