Question 1 of 5
A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?
Correct Answer: C
Rationale: The correct answer is C: To increase reabsorption of water in the renal tubules. Vasopressin, also known as antidiuretic hormone (ADH), works by increasing the reabsorption of water in the renal tubules, which helps to concentrate urine and reduce excessive urination in diabetes insipidus. Choice A is incorrect as vasopressin does not stimulate the pancreas to secrete insulin. Choice B is incorrect as vasopressin does not affect the absorption of glucose in the intestine. Choice D is incorrect as vasopressin's primary action is not to increase blood pressure, although it can have some vasoconstrictive effects.

Question 3 of 5
A nurse is preparing to administer morphine sulfate 2 mg IV bolus. Available is morphine sulfate 10 mg/mL. How many mL should the nurse administer per dose?
Correct Answer: A
Rationale: The nurse should administer 0.2 mL of morphine sulfate. To calculate this, divide the desired dose (2 mg) by the concentration of the available solution (10 mg/mL). 2 mg / 10 mg/mL = 0.2 mL. Therefore, the nurse should administer 0.2 mL of morphine sulfate. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided concentration and desired dose.
Question 4 of 5
A 55-year-old client has levothyroxine ordered. Which of the below past medical history concerns may contraindicate with her medication management of hypothyroidism?
Correct Answer: B
Rationale: The correct answer is B: Osteoporosis. Osteoporosis is a concern with levothyroxine as it can increase the risk for fractures, particularly in older adults. Levothyroxine treatment can exacerbate bone loss in individuals with osteoporosis. Choices A, C, and D are not directly contraindicated with levothyroxine therapy for hypothyroidism.
