Nursing Elites

1. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.

2. A client has a new prescription for Lisinopril. Which of the following adverse effects should the nurse monitor?

• A. Dry cough
• B. Weight gain
• C. Diarrhea
• D. Nausea

Correct answer: A

Rationale: The correct answer is 'A: Dry cough.' Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. If the client experiences this side effect, it is important to notify the healthcare provider for assessment and possible medication adjustment.

3. A client in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.

4. A client with HIV is starting therapy with zidovudine. The nurse should monitor the client for which of the following adverse effects of this medication?

• A. Fatigue
• B. Blurred vision
• C. Ringing in the ears
• D. Constipation

Correct answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to cause bone marrow suppression, resulting in decreased production of red blood cells and subsequent fatigue.

5. A client has a new prescription for Warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider immediately?

• A. INR of 4.0
• B. Potassium level of 4.5 mEq/L
• C. Sodium level of 140 mEq/L
• D. Creatinine level of 1.0 mg/dL

Correct answer: A

Rationale: An INR of 4.0 is above the therapeutic range for a client on Warfarin, indicating an increased risk of bleeding. This finding requires immediate reporting to the provider for appropriate intervention to prevent complications associated with excessive anticoagulation. Potassium, sodium, and creatinine levels are within normal ranges and are not directly related to the risk of bleeding in a client on Warfarin therapy.
