ATI Capstone Pharmacology Assessment 1
1. A client prescribed hydromorphone for severe pain has a decreased respiratory rate from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?
- A. Flumazenil
- B. Naloxone
- C. Activated charcoal
- D. Aluminum hydroxide
Correct answer: B
Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.
2. A client is receiving magnesium sulfate for the management of preeclampsia. Which of the following client assessments should the nurse monitor to prevent complications of therapy?
- A. Bowel sounds
- B. Deep tendon reflexes
- C. Oxygen saturation
- D. Fluid balance
Correct answer: B
Rationale: The correct answer is deep tendon reflexes. Monitoring deep tendon reflexes is crucial to assess for magnesium toxicity during therapy for preeclampsia. Magnesium sulfate can lead to neuromuscular blockade, reflected by decreased or absent deep tendon reflexes. Assessing bowel sounds (choice A) is important for gastrointestinal function but is not directly related to magnesium sulfate therapy. Oxygen saturation (choice C) is vital for respiratory status but is not specifically linked to magnesium sulfate administration. Fluid balance (choice D) is essential but does not directly correlate with monitoring for complications of magnesium sulfate therapy in the context of preeclampsia.
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 caring for a client with diabetes and a new prescription for 14 units of regular insulin and 28 units of NPH insulin subcutaneously at breakfast daily. What is the total number of units of insulin that the nurse should prepare in the insulin syringe?
- A. 14 units
- B. 28 units
- C. 32 units
- D. 42 units
Correct answer: D
Rationale: The nurse should combine both orders of insulin in the same syringe. To prepare the correct dose, the nurse should withdraw the regular insulin first (14 units) and then the NPH insulin (28 units), totaling 42 units. This combination ensures the client receives the prescribed doses of both types of insulin. Choices A, B, and C are incorrect because the nurse needs to prepare and administer both types of insulin as prescribed, resulting in a total of 42 units in the syringe.
5. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?
- A. Hemoglobin (Hgb)
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.
