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 55-year-old client has levothyroxine ordered. Which of the below past medical history concerns may contraindicate with her medication management of hypothyroidism?
- A. Scleroderma
- B. Osteoporosis
- C. Asthma
- D. Peripheral Vascular Disease
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.
3. A client is receiving a dopamine infusion via a peripheral IV. Which of the following actions should the nurse take if the IV site appears infiltrated?
- A. Slow the infusion and continue to monitor the site
- B. Stop the infusion
- C. Apply a warm compress to the site
- D. Apply a cold compress to the site
Correct answer: B
Rationale: When an IV site appears infiltrated, it indicates that the medication is leaking into the surrounding tissues. In such a situation, the infusion should be stopped immediately to prevent further tissue damage. Choice A is incorrect because slowing the infusion would still allow the medication to leak into the tissues. Choices C and D are also incorrect as applying compresses can exacerbate the tissue damage caused by infiltration.
4. 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.
5. A nurse is reviewing a client's medication regimen. Which of the following medications places the client at increased risk for digoxin toxicity?
- A. Calcium channel blockers
- B. Potassium-sparing diuretics
- C. Beta blockers
- D. Loop diuretics
Correct answer: D
Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.
