1. While assisting in caring for a pregnant client receiving intravenous magnesium sulfate for preeclampsia management, a nurse notes the client's absent deep tendon reflexes. What determination should the nurse make based on this data?
- A. The magnesium sulfate is effective.
- B. The infusion rate needs to be increased.
- C. The client is experiencing cerebral edema.
- D. The client is experiencing magnesium toxicity.
Correct answer: D
Rationale: When a pregnant client receiving intravenous magnesium sulfate for preeclampsia management exhibits absent deep tendon reflexes, this indicates magnesium toxicity. Magnesium toxicity can occur as a complication of magnesium sulfate therapy, leading to suppressed reflexes. It is crucial for the nurse to recognize this sign promptly and report it to prevent further complications or harm to the client.
2. Which of the following herbal therapies would be prescribed for its use as an antispasmodic? Select all that apply.
- A. Aloe
- B. Kava
- C. Ginger
- D. Chamomile
Correct answer: D
Rationale: Chamomile is known for its antispasmodic properties. It helps in relaxing muscles and reducing spasms. Aloe is a laxative, kava has anxiolytic and sedative effects, and ginger is commonly used to relieve nausea.
3. A client with chronic pain is prescribed transdermal fentanyl (Duragesic) patches. Which instruction should the nurse include in the teaching plan?
- A. Apply the patch to a different site each time.
- B. Avoid using heating pads over the patch.
- C. Change the patch every 72 hours.
- D. Remove the old patch before applying the new one.
Correct answer: B
Rationale: Clients using transdermal fentanyl (Duragesic) patches should avoid using heating pads over the patch as heat can increase the release of the medication, potentially leading to overdose. The patch should be applied to a different site each time, changed every 72 hours, and the old patch should be removed before applying a new one to prevent accidental overdose or excessive drug absorption.
4. A healthcare professional is preparing to administer digoxin (Lanoxin), 0.125 mg orally, to a client with heart failure. Which vital sign is most important for the healthcare professional to check before administering the medication?
- A. Heart rate
- B. Temperature
- C. Respirations
- D. Blood pressure
Correct answer: A
Rationale: Before administering digoxin, it is essential to assess the client's heart rate as this medication directly affects cardiac function. Monitoring the heart rate helps identify if it is within the acceptable range for administering digoxin. A pulse rate below 60 beats per minute warrants withholding the medication to prevent potential adverse effects like bradycardia or cardiac arrhythmias.
5. A client is receiving sulfisoxazole. Which of the following should be included in the list of instructions?
- A. Restrict fluid intake.
- B. Maintain a high fluid intake.
- C. If the urine turns dark brown, call the healthcare provider (HCP) immediately.
- D. Decrease the dosage when symptoms are improving to prevent an allergic response.
Correct answer: B
Rationale: When a client is taking sulfisoxazole, it is important to maintain a high fluid intake. Each dose of sulfisoxazole should be taken with a full glass of water, as the medication is more soluble in alkaline urine. Restricting fluid intake is not recommended as it can lead to inadequate hydration. Dark brown urine may be a side effect of some forms of sulfisoxazole but does not necessarily warrant immediate notification of the healthcare provider unless accompanied by other concerning symptoms. Decreasing the dosage when symptoms improve is not advised as it may lead to treatment failure or the development of resistance.
