The nurse is caring for a 3-year-old child who has been recently diagnosed with cystic fibrosis. Which discharge instruction by the nurse is most important to promote pulmonary function?
- A. Chest physiotherapy should be performed before meals and at bedtime
- B. Cough suppressants can be used up to four times a day for relief
- C. Oxygen should be given through a nasal cannula between 4-6 L/min
- D. Exercise is discouraged in order to preserve pulmonary vital capacity
Correct Answer: B
Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

A 13-year-old client with type 1 diabetes is admitted to the hospital with a blood glucose level of 450 mg/dL. The client is lethargic and has fruity-smelling breath. What is the nurse's priority action?
- A. Administer insulin as prescribed
- B. Start an IV infusion of normal saline
- C. Check the client's urine for ketones
- D. Monitor the client's vital signs
Correct Answer: B
Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.
The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?
- A. The aortic semilunar valve obstructs blood flow into the systemic circulation
- B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
- C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
- D. An opening in the atrial septum causes a murmur due to a turbulent left to right shunt
Correct Answer: B
Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.
What is the priority intervention for a 16-year-old client with a history of depression who is brought to the emergency department after taking an overdose of acetaminophen?
- A. Administer activated charcoal
- B. Place the client on continuous cardiac monitoring
- C. Prepare for gastric lavage
- D. Administer N-acetylcysteine as prescribed
Correct Answer: D
Rationale: The priority intervention for a client who has taken an acetaminophen overdose is to administer N-acetylcysteine promptly. N-acetylcysteine is the antidote for acetaminophen overdose and helps prevent liver damage. Activated charcoal may be used in certain cases, but N-acetylcysteine takes precedence as it directly counteracts the toxic effects of acetaminophen. Continuous cardiac monitoring and gastric lavage are not the priority interventions for acetaminophen overdose. Administering N-acetylcysteine is crucial to prevent liver damage and address the overdose, making it the most urgent action in this scenario.
The mother of a 9-month-old, diagnosed with respiratory syncytial virus (RSV) yesterday, calls the clinic to inquire if it will be all right to take her infant to the first birthday party of a friend's child the following day. What response should the nurse provide this mother?
- A. The child will no longer be contagious, so no need to take any further precautions.
- B. Ensure there are no children under the age of 6 months around the infected child.
- C. The child can be around other children but should wear a mask at all times.
- D. Do not expose other children to RSV. It is highly contagious even without direct contact.
Correct Answer: D
Rationale: The correct answer is D. RSV is highly contagious, even without direct contact. It is important to prevent the spread of the virus to other children, so the infected child should not attend the birthday party to avoid exposing other children to RSV. This is crucial to protect the health of other children who may be more vulnerable to the virus. Choices A, B, and C are incorrect. Choice A is incorrect as RSV remains contagious for a period of time, and precautions should be taken to prevent its spread. Choice B is incorrect because the age limit specified is not a reliable measure to prevent transmission. Choice C is incorrect as wearing a mask may not be sufficient to prevent the spread of RSV in a social setting like a birthday party.
The mother of a 9-month-old girl provides the practical nurse with information about her daughter's diet. Which statement by the mother may indicate why the infant has been diagnosed with iron-deficiency anemia?
- A. She almost never drinks sugary water.
- B. She has been on whole milk for 7 months.
- C. She likes to chew on bread as a snack.
- D. She doesn't like to eat peaches or pears.
Correct Answer: B
Rationale: The correct answer is B. Infants should not be given cow's milk before 1 year of age as it can interfere with iron absorption and lead to anemia. Choice A is incorrect as avoiding sugary water is actually a good practice. Choice C is unrelated to iron-deficiency anemia. Choice D, not liking peaches or pears, is also not directly related to iron-deficiency anemia.
