The nurse prepares to administer digoxin (Lanoxin) to a newborn with a diagnosis of heart failure and notes that the apical rate is 140 beats per minute. Which nursing action is appropriate?
- A. Hold the medication
- B. Administer the digoxin
- C. Notify the healthcare provider
- D. Recheck the apical rate in 1 hour
Correct Answer: B
Rationale: An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly used to treat heart failure by increasing the strength and efficiency of the heart's contractions. Since the heart rate is within the normal range, there is no need to hold the medication or notify the healthcare provider. Rechecking the apical rate in an hour is unnecessary as the heart rate is not alarming. Therefore, the appropriate nursing action is to administer the digoxin.

Which nursing instruction should the nurse discuss with the client who is receiving glucocorticoids for Addison's disease?
- A. Discuss the importance of tapering medications when discontinuing medication
- B. Explain that the dose will need to be decreased during times of stress or infection
- C. Instruct the client to take medication on an empty stomach with a glass of water
- D. Encourage the client to wear a MedicAlert bracelet and carry a card in the wallet
Correct Answer: A
Rationale: The correct answer is to discuss the importance of tapering medications when discontinuing medication. Tapering glucocorticoids is crucial to prevent adrenal insufficiency, which can occur if the medication is stopped abruptly. Choice B is incorrect because it focuses on adjustments during stress or infection, not discontinuation. Choice C is unrelated to the management of glucocorticoids. Choice D is important for emergency identification but is not directly related to medication management.

- A. The nurse repeats the information as indicated by the client's questions
- B. The nurse teaches all the information needed by the client in one session
- C. The nurse uses a video to explain with medical terms to the client
- D. The nurse waits until the client asks questions about the surgery
Correct Answer: A
Rationale: Choice A is the best method of applying adult teaching principles because repeating information and addressing the client's questions as they arise is effective for reinforcing learning in adults. This approach allows for clarification of doubts and ensures that the client understands the information provided. Choice B is incorrect as teaching all the information in one session may overwhelm the client and hinder retention. Choice C is incorrect as using medical terms without ensuring the client's understanding may lead to confusion. Choice D is incorrect because waiting for the client to ask questions may result in missed opportunities to address important information proactively.
A healthcare provider is caring for a client who takes an antidepressant and oral contraceptives. Which herbal supplement should the healthcare provider educate the client about due to a drug-herb interaction?
- A. Iron supplement
- B. Garlic
- C. Green tea
- D. St. John's Wort
Correct Answer: D
Rationale: The correct answer is D, St. John's Wort. St. John's Wort can interact with antidepressants and oral contraceptives, potentially reducing their efficacy. Iron supplement, garlic, and green tea are not typically known to have significant interactions with antidepressants or oral contraceptives, making them less likely to impact the client's treatment.
