Nursing Elites

1. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

2. When teaching a group of mothers of young children about emergency care for poisoning, which of the following statements should be included?

• A. Induce vomiting immediately after the poison ingestion
• B. Call the local Poison Control Center after inducing vomiting
• C. Call the Poison Control Center prior to any interventions
• D. Take the child to the emergency department before calling the Poison Control Center

Correct answer: C

Rationale: The correct statement to include when teaching about emergency care for poisoning is to call the Poison Control Center prior to any interventions. This is important because the Poison Control Center can provide guidance on the appropriate steps to take based on the type of poisoning, the amount ingested, and the age of the child. Inducing vomiting without professional advice can sometimes do more harm than good. Choice A is incorrect because inducing vomiting immediately is not recommended without consulting with professionals. Choice B is incorrect as it suggests calling the Poison Control Center after inducing vomiting, which is not the recommended sequence. Choice D is incorrect because it is advisable to contact the Poison Control Center first before taking the child to the emergency department.

3. The nurse is teaching a client about postoperative care following a total knee arthroplasty. What instruction should the nurse prioritize?

• A. Begin ambulation as soon as possible.
• B. Use continuous passive motion therapy to maintain joint mobility.
• C. Avoid putting weight on the affected leg.
• D. Apply ice packs to reduce pain and swelling.

Correct answer: B

Rationale: The correct answer is B: 'Use continuous passive motion therapy to maintain joint mobility.' Continuous passive motion therapy is crucial in postoperative care following a total knee arthroplasty as it helps prevent stiffness and maintain joint mobility. Ambulation is important but should be guided and not immediate. Avoiding putting weight on the affected leg is also essential initially to prevent complications. Applying ice packs can help reduce pain and swelling, but it is not the priority instruction for maintaining joint mobility and preventing stiffness.

4. A client is admitted with pneumonia and is started on antibiotics. After 3 days, the client reports difficulty breathing and a rash. What is the nurse's first action?

• A. Administer epinephrine
• B. Discontinue the antibiotic
• C. Assess the client's oxygen saturation
• D. Call the healthcare provider

Correct answer: B

Rationale: The client's difficulty breathing and rash suggest a possible allergic reaction to the antibiotic. The first action the nurse should take is to discontinue the antibiotic to prevent further exposure. Administering epinephrine should only be done in severe cases of anaphylaxis, which is not indicated solely by difficulty breathing and rash. While assessing the client's oxygen saturation is important, discontinuing the potential allergen takes precedence. Contacting the healthcare provider should be done after discontinuing the antibiotic and assessing the client to report the situation and seek further guidance.

5. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide?

• A. Avoid foods high in vitamin K, such as spinach.
• B. Report any signs of bleeding, such as bruising or nosebleeds.
• C. Take the medication on an empty stomach.
• D. Monitor for changes in blood pressure.

Correct answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.
