ATI Capstone Pharmacology Assessment 1
1. A nurse is administering metformin to a client with type 2 diabetes. Which of the following adverse effects should the nurse monitor for in this client?
- A. Diarrhea
- B. Hyperglycemia
- C. Hypoglycemia
- D. Lactic acidosis
Correct answer: D
Rationale: The correct answer is D, Lactic acidosis. Lactic acidosis is a rare but serious adverse effect of metformin use. Metformin is not known to cause hyperglycemia or hypoglycemia. Diarrhea is a common gastrointestinal side effect of metformin but is not as serious as lactic acidosis, which requires immediate medical attention.
2. A nurse is preparing to administer nitroglycerin ointment to a client. Which of the following actions should the nurse take?
- A. Apply the ointment to the client's hairless chest
- B. Rub the ointment gently into the skin
- C. Cover the applied ointment with a transparent dressing
- D. Massage the ointment into the skin
Correct answer: A
Rationale: The correct action is to apply the nitroglycerin ointment to a hairless area of the client's chest, back, or upper arms. This allows for better absorption of the medication. Choice B is incorrect because rubbing the ointment gently into the skin may be appropriate, but the primary action is to ensure application on a hairless area. Choice C is incorrect as covering the ointment with a transparent dressing is not a standard practice for nitroglycerin ointment administration. Choice D is incorrect because massaging the ointment into the skin is not recommended, as it can alter absorption rates.
3. A client has been prescribed vasopressin for the treatment of diabetes insipidus. What is the expected pharmacologic action of this medication?
- A. To stimulate the pancreas to secrete insulin
- B. To slow the absorption of glucose in the intestine
- C. To increase reabsorption of water in the renal tubules
- D. To increase blood pressure
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.
4. 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?
- A. 0.2 mL
- B. 0.4 mL
- C. 0.6 mL
- D. 0.8 mL
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.
5. A nurse is caring for a client receiving theophylline for chronic obstructive pulmonary disease (COPD). Which of the following client findings indicates the need for immediate intervention?
- A. Productive cough
- B. Drowsiness
- C. Vomiting
- D. Polyuria
Correct answer: D
Rationale: Polyuria is a sign of theophylline toxicity and requires immediate intervention. Theophylline toxicity can lead to serious complications, and polyuria is a concerning symptom that indicates the need for urgent medical attention. Productive cough, drowsiness, and vomiting are common side effects of theophylline but are not typically indicative of immediate life-threatening issues like polyuria in the context of theophylline toxicity.
