Question 1 of 5
A nurse is caring for a client who is taking digoxin to treat heart failure. Which of the following factors predisposes this client to developing digoxin toxicity?
Correct Answer: A
Rationale: The correct answer is A: Taking a high-ceiling diuretic. High-ceiling diuretics, like furosemide, can lead to hypokalemia by increasing potassium excretion, which can potentiate the risk of digoxin toxicity as digoxin competes with potassium for binding sites on the myocardial cell membrane.
Therefore, when a client is taking digoxin along with a high-ceiling diuretic, the risk of digoxin toxicity increases. The other choices, B, C, and D, do not directly predispose the client to digoxin toxicity. HMG COA reductase inhibitors are used to lower cholesterol levels and do not interact with digoxin. COPD and a prolapsed mitral valve are unrelated to the risk of digoxin toxicity.
Question 2 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: C
Rationale: The correct answer is C: Oxycodone causes central nervous system depression. Oxycodone is an opioid analgesic that acts on the central nervous system (CNS) to relieve pain. One of the side effects of opioids like oxycodone is respiratory depression, which can lead to a decreased respiratory rate. This occurs because opioids suppress the activity of the brainstem respiratory centers, resulting in shallow breathing and decreased respiratory rate.
Choices A, B, and D are incorrect as they do not directly relate to the respiratory depression caused by oxycodone.
Choice A is related to local anesthetics, not opioids.
Choice B is related to migraine treatment.
Choice D is related to NSAIDs, not opioids.
Question 3 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: B
Rationale: The correct answer is B: Calcium. Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Calcium can interfere with the absorption of levothyroxine, so it is recommended to wait at least 4 hours after taking levothyroxine before consuming calcium supplements. Ginkgo biloba, Vitamin C, and Zinc do not significantly interfere with levothyroxine absorption, so there is no need to wait specifically for them. Calcium is the correct choice because of its known interference with levothyroxine absorption.

Nurses' Notes
Laboratory Results
0900:
The client is being seen in the office. The client reports feeling fatigued and having a heavy menstrual cycle the past year.
Upon assessment, the client's conjunctiva and mucosal membranes are pale. Provider notified and laboratory samples to be drawn.

Question 4 of 5
For each of the statements made by the client, click to specify whether the statement indicates an understanding or no understanding of the teaching provided. Options: A. 'If I experience black stools, I should notify my provider.' B. 'I should avoid taking antacids while on this medication.' C. 'I should take my medications on an empty stomach.' D. 'I should rinse my mouth after taking this medication.' E. 'I should take this medication with orange juice.'
Correct Answer: B,D,E
Rationale:
Correct Answer: B, D, E
Explanation:
B. "I should avoid taking antacids while on this medication." - Correct. Antacids can interfere with the absorption of certain medications.
D. "I should rinse my mouth after taking this medication." - Correct. Some medications can cause oral irritation, so rinsing the mouth is necessary.
E. "I should take this medication with orange juice." - Incorrect. Taking medication with specific juices can affect absorption. It is not recommended to take this medication with orange juice.

Question 5 of 5
A nurse is assessing a client who has started taking theophylline. Which of the following client findings should indicate to the nurse that the medication is effective?
Correct Answer: B
Rationale: The correct answer is B: Decreased wheezing. Theophylline is a bronchodilator used to treat respiratory conditions like asthma by relaxing the muscles in the airways. When theophylline is effective, it helps to open up the airways, leading to decreased wheezing. This indicates improved airflow and better respiratory function. Increased blood pressure (
A) is not a direct indication of theophylline effectiveness. Decreased urine output (
C) could suggest dehydration or kidney issues, not necessarily related to theophylline. Increased level of consciousness (
D) is a general assessment parameter and not specific to theophylline effectiveness.
