1. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.
2. A nurse is providing instructions to a client who has a prescription for Amoxicillin and Clarithromycin to treat a Peptic Ulcer. Which of the following information should the nurse include in the teaching?
- A. Take these medications with foo '
- B. These medications can turn your stool black.'
- C. These medications can cause photosensitivity.'
- D. The purpose of these medications is to decrease the pH of gastric juices in the stomach.'
Correct answer: A
Rationale: The nurse should instruct the client to take these medications with food to reduce GI disturbances.
3. A healthcare professional is preparing to administer an IV antibiotic to a client who has a systemic infection. Which of the following actions should the professional take first?
- A. Administer an antihistamine prior to the antibiotic.
- B. Monitor the client's urine output.
- C. Check the client's allergy history.
- D. Assess the client's vital signs.
Correct answer: C
Rationale: The first action the healthcare professional should take is to check the client's allergy history before administering the antibiotic to prevent a potential allergic reaction. It is crucial to identify any known allergies to antibiotics to ensure the client's safety and well-being. Administering an antihistamine prior to the antibiotic (Choice A) is not recommended unless an allergic reaction occurs. Monitoring the client's urine output (Choice B) and assessing the client's vital signs (Choice D) are important but not the first step in this situation. Checking the client's allergy history takes precedence to prevent adverse reactions.
4. What is a common side effect that typically occurs with the initial therapy of Nitroglycerine as a result of increased vasodilation?
- A. Abdominal cramps
- B. Calf pain
- C. Headache
- D. Blurred vision
Correct answer: C
Rationale: Headache is a common side effect associated with the initial therapy of Nitroglycerine due to its vasodilatory properties. The vasodilation caused by Nitroglycerine leads to relaxation of blood vessels, including those in the head, which can result in headaches. This side effect is considered normal and is often transient, diminishing with continued use of the medication.
5. A client is receiving discharge teaching for Metronidazole prescribed for an infection. Which statement by the client indicates an understanding of the teaching?
- A. I should avoid drinking alcohol while taking this medication.
- B. I should take this medication with food.
- C. I should increase my intake of dairy products while taking this medication.
- D. I should avoid taking dairy products while taking this medication.
Correct answer: A
Rationale: The correct answer is A. Alcohol should be avoided while taking Metronidazole because it can lead to a disulfiram-like reaction, causing severe nausea and vomiting. It is important for the client to understand this to prevent adverse reactions and ensure the effectiveness of the medication in treating the infection. Choices B, C, and D are incorrect because taking Metronidazole with food is recommended to decrease gastrointestinal upset, and there is no specific need to increase or avoid dairy products while taking this medication.
