Extract:
Question 1 of 5
A nurse is teaching a client about how to use her new hearing aids. Which of the following statements should the nurse identify as an indication that the client needs further instruction?
Correct Answer: A
Rationale: Cleaning hearing aids with alcohol wipes is incorrect as alcohol can damage the hearing aids.
Question 2 of 5
A nurse is caring for a client who overdosed on morphine and has a respiratory rate of 6/min. Which medication should the nurse plan to administer?
Correct Answer: D
Rationale: Naloxone is the standard treatment for opioid overdose, including morphine. It is an opioid antagonist that binds to opioid receptors in the brain, effectively reversing the effects of opioids and restoring normal respiration.
Question 3 of 5
The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin?
Correct Answer: B
Rationale: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Potassium and digoxin compete for binding at the same sites in the heart, and low potassium levels enhance digoxin's effects, potentially leading to toxicity.
Question 4 of 5
A nurse is admitting a client who is dehydrated. Which BUN level should the nurse expect the client to have upon admission? (Normal BUN 10-20)
Correct Answer: D
Rationale: A BUN level of 31 mg/dL is elevated and consistent with the expected findings in a dehydrated client. Dehydration can lead to increased BUN levels due to decreased renal blood flow and glomerular filtration rate.
Question 5 of 5
A nurse is assessing a client who has chronic venous insufficiency. Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Edema is a hallmark of chronic venous insufficiency, caused by impaired venous return and fluid pooling in the lower extremities.
