1. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
2. A nurse is providing teaching to a newly licensed nurse about metoclopramide. The nurse should include in the teaching that which of the following conditions is a contraindication to this medication?
- A. Hyperthyroidism
- B. Intestinal obstruction
- C. Glaucoma
- D. Low blood pressure
Correct answer: B
Rationale: The correct answer is B: Intestinal obstruction. Metoclopramide is contraindicated in clients with intestinal obstruction due to its prokinetic effects, which could exacerbate the condition. Choices A, C, and D are incorrect because metoclopramide is not contraindicated in hyperthyroidism, glaucoma, or low blood pressure. Hyperthyroidism, glaucoma, and low blood pressure are not specific contraindications for metoclopramide use, and this medication is commonly prescribed for conditions like gastroesophageal reflux disease and diabetic gastroparesis.
3. A nurse is assessing a client who has a new prescription for chlorpromazine to treat schizophrenia. The client has a mask-like facial expression and is experiencing involuntary movements and tremors. Which of the following medications should the nurse anticipate administering?
- A. Amantadine
- B. Bupropion
- C. Phenelzine
- D. Hydroxyzine
Correct answer: A
Rationale: The correct answer is Amantadine. Amantadine is used to treat extrapyramidal symptoms, such as mask-like facial expressions, involuntary movements, and tremors, which are common side effects of antipsychotic medications like chlorpromazine. Bupropion is an antidepressant and not indicated for treating these symptoms. Phenelzine is a monoamine oxidase inhibitor used for depression and anxiety disorders, not for extrapyramidal symptoms. Hydroxyzine is an antihistamine used for anxiety and allergic conditions, not for the side effects described in the client.
4. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following indicates she is dehydrated?
- A. Urine specific gravity of 1.035
- B. Oliguria
- C. Increased urine concentration
- D. Dry mucous membranes
Correct answer: A
Rationale: The correct answer is A: Urine specific gravity of 1.035. A urine specific gravity greater than 1.030 indicates dehydration as the kidneys conserve water in response to dehydration. Choice B, oliguria, refers to decreased urine output, which can be a sign of dehydration but is not specific to it. Choice C, increased urine concentration, is a general term and does not directly indicate dehydration. Choice D, dry mucous membranes, can be a sign of dehydration but is not as specific as a urine specific gravity greater than 1.030.
5. A nurse is reviewing laboratory values for a client who reports fatigue and cold intolerance. The client has an increased thyroid stimulating hormone (TSH) level and a decreased total T3 and T4 level. The nurse should anticipate a prescription for which of the following medications?
- A. Methimazole
- B. Somatropin
- C. Levothyroxine
- D. Propylthiouracil
Correct answer: C
Rationale: Levothyroxine is the correct answer. In this scenario, the client's elevated TSH and decreased T3 and T4 levels indicate hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine is a synthetic form of thyroid hormone that is used to replace or supplement the body's naturally produced thyroid hormones. Methimazole and Propylthiouracil are used to treat hyperthyroidism by reducing the production of thyroid hormones. Somatropin is a growth hormone used to treat growth hormone deficiency and other conditions unrelated to thyroid disorders.
