ATI Capstone Pharmacology Assessment 1

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.

Correct Answer: A

Rationale: Corrected Rationale: First-dose orthostatic hypotension can occur with doxazosin. The nurse should advise the client to change positions slowly and lie down if dizziness occurs. Choice B is incorrect because it does not address the potential side effect of dizziness. Choice C and D are also incorrect as there is no specific dietary restriction related to doxazosin mesylate.

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.

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.

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.
