1. How should the healthcare provider schedule the administering of propylthiouracil (PTU)?

Correct answer: D

Rationale: Administering iodine one hour before PTU is crucial to ensure proper absorption and effectiveness of PTU. This timing helps optimize the therapeutic benefits of PTU by allowing it to be absorbed efficiently without interference from iodine, ultimately leading to better treatment outcomes for the patient. Choices A, B, and C are incorrect because offering both drugs together with a meal, giving parental dose once every 24 hours, and scheduling both medications at bedtime do not address the specific timing requirement of administering iodine before PTU for optimal absorption.

2. What instruction should the nurse include in the teaching plan for a client prescribed etanercept for rheumatoid arthritis?

Correct answer: A

Rationale: The correct instruction for a client prescribed etanercept is to rotate injection sites to prevent irritation and ensure proper absorption. Changing sites will help prevent skin irritation and ensure that the medication is absorbed effectively. This practice also reduces the risk of injection site reactions and discomfort. It is essential to follow this instruction to promote optimal medication delivery and minimize adverse effects. Choice B is incorrect because etanercept can be taken with or without food, and it is not specifically indicated to be taken with food to reduce gastrointestinal upset. Choice C is incorrect as there is no specific association between etanercept and sunlight exposure. Choice D is incorrect because while it is important to notify the healthcare provider of signs of infection, this is not the primary instruction related to the administration of etanercept.

3. Which action should be taken to assess for analgesic tolerance in a client who is unable to communicate?

Correct answer: C

Rationale: In clients who are unable to communicate, observing for pain behaviors is crucial in assessing analgesic tolerance. Changes in pain behaviors can indicate if the current analgesic regimen is effective or if tolerance has developed. Therefore, closely observing the client for pain behaviors before the next analgesic dose helps healthcare providers evaluate the client's response to pain management. Reviewing laboratory values may not directly reflect analgesic tolerance. Prolonging the interval between doses and monitoring vital signs may not provide direct information on analgesic tolerance. Relying solely on family members to report pain behaviors may not be as accurate or immediate as observing the client directly.

4. A client who is prescribed sildenafil for pulmonary hypertension calls the clinic for advice. Which condition should the practical nurse notify the health care provider immediately and instruct the client to stop taking the medication?

Correct answer: A

Rationale: The correct answer is A. If a client prescribed sildenafil for pulmonary hypertension experiences vision and/or hearing loss or an erection lasting more than 4 hours, the practical nurse should instruct the client to discontinue the medication immediately and notify the health care provider. These symptoms could indicate serious side effects that require prompt medical attention to prevent complications. Choices B, C, and D are incorrect because an erection lasting more than 2 hours (not 4 hours as stated in choice B) is a critical adverse effect that warrants immediate medical attention. Nasal congestion (choice C) and feeling flushed (choice D) are common side effects of sildenafil and typically do not necessitate immediate discontinuation of the medication or emergency intervention.

5. A client has been prescribed losartan. Which change in data indicates to the practical nurse (PN) that the desired effect of this medication has been achieved?

Correct answer: D

Rationale: The correct answer is D. Losartan is prescribed for the treatment of hypertension. The desired effect of losartan is to reduce blood pressure. Therefore, a reduction in blood pressure from 160/90 to 130/80 mm Hg indicates that the desired effect of the medication has been achieved. Choices A, B, and C are not specific effects of losartan and do not directly relate to the expected outcomes of this medication. Dependent edema, serum HDL levels, and pulse rate are not typically influenced by losartan, making choices A, B, and C incorrect.
