ATI Capstone Pharmacology Assessment 1
1. 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.
2. A healthcare provider is preparing to administer a measles, mumps, and rubella (MMR) vaccine to an adult client. Which of the following is a contraindication to this vaccine?
- A. The possibility of pregnancy within 4 weeks
- B. Client allergy to strawberries
- C. Client history of genital herpes
- D. The possibility of overseas travel in the next month
Correct answer: A
Rationale: The correct answer is A. Pregnancy or the possibility of pregnancy within 4 weeks is a contraindication for receiving the MMR vaccine. Choice B, client allergy to strawberries, is not a contraindication to the MMR vaccine. Choice C, client history of genital herpes, is not a contraindication for the MMR vaccine. Choice D, the possibility of overseas travel in the next month, is not a contraindication to the MMR vaccine.
3. A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?
- A. aPTT
- B. INR
- C. Serum glucose
- D. Bilirubin
Correct answer: B
Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.
4. Before administering blood products, which action should be taken?
- A. Assess the client's temperature
- B. Document client response
- C. Prime IV tubing with 0.45% sodium chloride
- D. Administer epinephrine
Correct answer: A
Rationale: Correct answer: Before administering blood products, the client's temperature must be assessed to establish a baseline and monitor for transfusion reactions. Choice B is incorrect because documenting client response should occur after administering the blood products. Choice C is incorrect as priming IV tubing with 0.45% sodium chloride is not directly related to assessing the client before administering blood products. Choice D is incorrect because administering epinephrine is not a routine action before administering blood products.
5. A client is prescribed propranolol. Which of the following client history findings would require the nurse to clarify this medication prescription?
- A. Asthma
- B. Hypertension
- C. Tachydysrhythmias
- D. Urolithiasis
Correct answer: A
Rationale: The correct answer is A: Asthma. Clients with asthma should avoid Beta2 Blockade agents like propranolol as they can lead to bronchoconstriction, potentially worsening asthma symptoms. Choice B, hypertension, is not a contraindication for propranolol; in fact, it is commonly prescribed for hypertension. Choice C, tachydysrhythmias, is often an indication for propranolol due to its antiarrhythmic properties. Choice D, urolithiasis, does not directly impact the use of propranolol.
