1. Which of the following is a key symptom of myocardial infarction (MI)?
- A. Chest pain.
- B. Shortness of breath.
- C. Nausea.
- D. Fatigue.
Correct answer: A
Rationale: The correct answer is A: Chest pain. Chest pain is a hallmark symptom of myocardial infarction (MI) due to inadequate blood flow to the heart muscle. This pain can be severe, crushing, or squeezing, and may radiate to the left arm, jaw, or back. Shortness of breath (choice B), nausea (choice C), and fatigue (choice D) can accompany MI but are not as specific or characteristic as chest pain in diagnosing this condition. Therefore, chest pain is the primary symptom to recognize for suspected MI.
2. A nurse obtains a sterile urine specimen from a client’s Foley catheter. After applying a clamp to the drainage tubing distal to the injection port, which action should the nurse take next?
- A. Clamp another section of the tube to create a fixed sample section for retrieval.
- B. Insert a syringe into the injection port and aspirate the quantity of urine required.
- C. Clean the injection port cap of the drainage tubing with a povidone-iodine solution.
- D. Withdraw 10 mL of urine and discard it; then withdraw a fresh sample of urine.
Correct answer: C
Rationale: The correct next action for the nurse to take after applying a clamp to the drainage tubing distal to the injection port is to clean the injection port cap of the catheter drainage tubing with an appropriate antiseptic like povidone-iodine solution or alcohol. This step is crucial to prevent surface contamination before taking the urine sample. Clamping another section of the tube to create a fixed sample section or withdrawing and discarding urine are unnecessary and could lead to potential contamination. Inserting a syringe into the injection port and aspirating the required amount of urine directly from the catheter is the correct method for obtaining the urine sample, but cleaning the injection port cap should precede this step to ensure sterility.
3. The nurse is obtaining a health history from a new client who has a history of kidney stones. Which statement by the client indicates an increased risk for renal calculi?
- A. Eats a vegetarian diet with cheese 2 to 3 times a day
- B. Experiences additional stress since adopting a child
- C. Jogs more frequently than usual daily routine
- D. Drinks several bottles of carbonated water daily
Correct answer: D
Rationale: The correct answer is D. Drinking several bottles of carbonated water daily may contribute to renal calculi formation due to the high mineral content. Carbonated drinks can increase the risk of kidney stones due to their high levels of phosphoric acid and caffeine, which can lead to the formation of crystals in the urine. Choices A, B, and C are less likely to directly contribute to an increased risk of renal calculi compared to the excessive consumption of carbonated water.
4. A 58-year-old client who has been post-menopausal for five years is concerned about the risk for osteoporosis because her mother has the condition. Which information should the nurse offer?
- A. Osteoporosis is a progressive genetic disease with no effective treatment.
- B. Calcium loss from bones can be slowed by increasing calcium intake and exercise.
- C. Estrogen replacement therapy should be started to prevent the progression of osteoporosis.
- D. Low-dose corticosteroid treatment effectively halts the course of osteoporosis.
Correct answer: B
Rationale: Post-menopausal females are at risk for osteoporosis due to the cessation of estrogen secretion. While genetics can play a role, osteoporosis is not solely a genetic disease. Increasing calcium intake, along with vitamin D supplementation and weight-bearing exercise, can help prevent further bone loss by slowing down calcium loss from bones. Estrogen replacement therapy is no longer recommended as a first-line treatment for osteoporosis due to associated risks. Corticosteroid treatment is not typically used as a primary treatment for osteoporosis.
5. Which of the following symptoms would a healthcare provider expect to find in a patient with hyperkalemia?
- A. Muscle cramps.
- B. Hypertension.
- C. Bradycardia.
- D. Tachycardia.
Correct answer: D
Rationale: Tachycardia is the correct symptom to expect in a patient with hyperkalemia. Hyperkalemia, or high potassium levels in the blood, can affect the electrical activity of the heart. Increased potassium levels can lead to changes in the heart's rhythm, potentially causing tachycardia (rapid heart rate) or other cardiac arrhythmias. Muscle cramps (choice A) are not typically associated with hyperkalemia. Hypertension (choice B) is not a common symptom of hyperkalemia; in fact, high potassium levels can sometimes cause low blood pressure. Bradycardia (choice C), or a slow heart rate, is usually not a primary symptom of hyperkalemia; instead, hyperkalemia tends to be associated with faster heart rates or arrhythmias.
