1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?
- A. 0.8 mL
- B. 0.75 mL
- C. 0.5 mL
- D. 1 mL
Correct answer: A
Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.
2. A client with type 2 Diabetes Mellitus is starting Repaglinide. Which statement by the client indicates understanding of the administration of this medication?
- A. I'll take this medicine with my meals.
- B. I'll take this medicine 30 minutes before I eat.
- C. I'll take this medicine just before I go to bed.
- D. I'll take this medicine as soon as I wake up in the morning.
Correct answer: B
Rationale: The correct answer is B. Repaglinide causes a rapid, short-lived release of insulin. To ensure the insulin is available when food is digested, the client should take this medication 30 minutes before each meal. This timing aligns the medication with the expected postprandial rise in blood glucose levels, optimizing its effectiveness in controlling blood sugar levels. Choices A, C, and D are incorrect because taking Repaglinide with meals, just before bed, or as soon as waking up does not align with the medication's mechanism of action and timing needed for optimal effectiveness.
3. What is the correct medical term used to describe impaired blood flow in the coronary arteries?
- A. Myocardial infarction
- B. Angina pectoris
- C. Cerebrovascular accident
- D. Coronary heart disease
Correct answer: D
Rationale: The correct medical term for impaired blood flow in the coronary arteries is Coronary heart disease. This condition is characterized by a narrowing or blockage of the coronary arteries, leading to reduced blood flow to the heart muscle. Myocardial infarction (choice A) refers to a heart attack, which occurs when blood flow to a part of the heart is blocked. Angina pectoris (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. Cerebrovascular accident (choice C) is the medical term for a stroke, which occurs when blood flow to a part of the brain is interrupted.
4. A client is prescribed Propylthiouracil (PTU) for the treatment of Graves' disease. Which adverse effect should the client be instructed to report?
- A. Sore throat.
- B. Drowsiness.
- C. Urinary retention.
- D. Heat intolerance.
Correct answer: A
Rationale: The correct answer is A: Sore throat. A sore throat and fever can indicate agranulocytosis, a serious adverse effect of PTU that can lead to a decreased white blood cell count. This condition requires immediate medical attention to prevent complications. Choice B, drowsiness, is not typically associated with PTU and is not a common adverse effect that needs to be reported. Choice C, urinary retention, is not a typical adverse effect of PTU; therefore, it is not the correct answer. Choice D, heat intolerance, is a symptom commonly seen in hyperthyroidism, which PTU is used to treat, so it is not an adverse effect that needs to be specifically reported.
5. A healthcare professional is educating a client who is starting therapy with gemcitabine. Which of the following findings should the healthcare professional instruct the client to report?
- A. Dyspnea
- B. Constipation
- C. Tinnitus
- D. Dry mouth
Correct answer: A
Rationale: The healthcare professional should instruct the client to report dyspnea since it can indicate pulmonary toxicity, a severe adverse effect associated with gemcitabine therapy. Monitoring and reporting dyspnea promptly can help in early detection and management of potential serious complications. Constipation, tinnitus, and dry mouth are not typically associated with gemcitabine therapy and are not urgent findings requiring immediate reporting.
