1. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?
- A. Chest X-ray
- B. Sweat chloride test
- C. Pulmonary function test
- D. Sputum culture
Correct answer: B
Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.
2. Based on the information provided in this client’s medical record during labor, which intervention should the nurse implement?
- A. Apply oxygen at 10 L per minute via mask
- B. Stop the oxytocin infusion
- C. Turn the client to the right lateral position
- D. Continue monitoring the progress of labor
Correct answer: C
Rationale: Turning the client to the right lateral position is essential as it can improve fetal oxygenation and uterine blood flow, promoting better labor outcomes. This intervention helps relieve pressure on blood vessels, enhancing blood flow to the placenta and improving oxygen supply to the fetus. Applying oxygen at a specific rate may not address the underlying issue of compromised blood flow and oxygenation. Stopping the oxytocin infusion is not the priority unless medically indicated as it can affect labor progression. While monitoring the progress of labor is important, actively addressing the compromised fetal oxygenation and uterine blood flow by changing the client's position takes precedence in this scenario.
3. Non-nutrient substances found in plant foods that may demonstrate biological activity in the body are commonly known as ___
- A. Bioenhancements
- B. Inorganic fibers
- C. Phytochemicals
- D. Phytoactive chemicals
Correct answer: C
Rationale: Phytochemicals are bioactive compounds found in plant foods that may affect health. They are known for their potential health benefits, such as antioxidant and anti-inflammatory properties. Choices A, B, and D are incorrect. 'Bioenhancements' is not a term used to describe non-nutrient substances in plant foods. 'Inorganic fibers' do not refer to bioactive compounds found in plants. 'Phytoactive chemicals' is not a commonly used term in nutrition science to describe these compounds.
4. A 4-year-old child is admitted to the hospital with a diagnosis of epiglottitis. What is the priority nursing intervention?
- A. Administer antibiotics
- B. Provide humidified oxygen
- C. Keep the child NPO
- D. Position the child upright
Correct answer: C
Rationale: The priority nursing intervention for a 4-year-old child admitted to the hospital with epiglottitis is to keep the child NPO (nothing by mouth). Epiglottitis is a serious condition that can lead to airway obstruction. Keeping the child NPO helps prevent further compromise of the airway and reduces the risk of aspiration. Administering antibiotics may be necessary but ensuring the airway is not compromised takes precedence. Providing humidified oxygen is important for respiratory support, but not the priority over maintaining a patent airway. Positioning the child upright can help with breathing and comfort, but it does not directly address the immediate risk of airway compromise associated with epiglottitis.
5. A nurse obtains a prescription for wrist restraints for a client who is trying to pull out his NG Tube. Which of the following actions should the nurse take?
- A. Remove the restraints every 4 hours.
- B. Attach the restraints securely to the side of the client's bed.
- C. Apply the restraints to allow as little movement as possible.
- D. Allow room for two fingers to fit between the client's skin and the restraints.
Correct answer: D
Rationale: When using wrist restraints, it is important to allow room for two fingers to fit between the client's skin and the restraints. This practice ensures proper circulation and comfort for the client while still providing the necessary level of security. Choice A is incorrect because removing restraints every 4 hours may compromise the effectiveness of restraint use. Choice B is incorrect as restraints should not be attached to the side of the bed where they could cause harm or be tampered with by the client. Choice C is incorrect because allowing minimal movement may lead to discomfort and compromise proper circulation.
