Adult Health Exam 1
1. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?
- A. Discontinue the IV under physician's guidance
- B. Apply a warm compress to the site
- C. Notify the physician
- D. Document the appearance of the site and continue the bath
Correct answer: C
Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.
2. A client with hypothyroidism is being treated with levothyroxine (Synthroid). What is the most important information for the nurse to provide to the client?
- A. Take the medication on an empty stomach
- B. Monitor for signs of hyperthyroidism
- C. Expect to see results within a week
- D. Avoid exposure to sunlight
Correct answer: B
Rationale: The most important information for the nurse to provide to a client with hypothyroidism being treated with levothyroxine is to monitor for signs of hyperthyroidism. Too much levothyroxine can lead to symptoms of hyperthyroidism, indicating an overdose. Choice A is incorrect as levothyroxine is usually taken on an empty stomach to ensure optimal absorption. Choice C is inaccurate as it may take weeks to months to see the full effects of levothyroxine therapy due to the need for dosage adjustments. Choice D is unrelated to levothyroxine therapy and is not a crucial concern for this specific medication.
3. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?
- A. The IV fluids are infusing into the subcutaneous tissues
- B. The infusion pump is functioning properly
- C. The insertion date should be verified and the IV discontinued
- D. The site is inflamed and should be reported
Correct answer: B
Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.
4. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?
- A. 400 mg/mL
- B. 500 mg/mL
- C. 450 mg/mL
- D. 350 mg/mL
Correct answer: A
Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
5. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?
- A. Neutralizes stomach acid
- B. Reduces gastric acid production
- C. Forms a protective barrier over ulcers
- D. Increases gastric mucus production
Correct answer: B
Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.
