Correct Answer: D

Rationale: The correct answer is D. Patients with Parkinson's disease should not stop taking their medication if they feel better, as doing so can worsen symptoms. It is crucial for patients to continue their prescribed medication regimen as directed by their healthcare provider. Choices A, B, and C are all appropriate actions that promote the well-being of a client with Parkinson's disease. Choice A emphasizes medication adherence, which is vital for symptom management. Choice B addresses a common issue in Parkinson's patients and shows an understanding of the importance of dietary management. Choice C highlights the significance of physical activity in maintaining mobility, which is essential for overall quality of life in Parkinson's disease.

Correct Answer: A

Rationale: When performing nasotracheal suctioning for a client with a respiratory infection, the nurse should apply intermittent suction when withdrawing the catheter. This technique helps minimize mucosal damage and is considered best practice. Choice B, suctioning continuously while inserting the catheter, is incorrect as continuous suctioning can cause trauma to the airway. Choice C, suctioning intermittently while inserting the catheter, is also incorrect as it can increase the risk of hypoxia and mucosal damage. Choice D, using a Yankauer suction device, is not appropriate for nasotracheal suctioning as it is typically used for oral suctioning. Therefore, the correct technique is to apply intermittent suction when withdrawing the catheter to ensure effective and safe suctioning.

Correct Answer: D

Rationale: The most appropriate action for the nurse to take is to put the client's wedding ring in a locked storage unit for safekeeping. This ensures that the ring is secure and minimizes the risk of loss or damage. Choices A, B, and C do not provide the same level of security and protection as placing the ring in a locked storage unit. Pinning it to the hospital gown (Choice A) may not be secure and could still lead to loss. Placing it in the client's drawer (Choice B) may not guarantee its safety. Holding onto it until a family member retrieves it (Choice C) leaves the ring vulnerable to misplacement or theft.

Correct Answer: C

Rationale: The correct answer is C: Rash, blood dyscrasias, and severe depression are serious side effects of haloperidol that necessitate withholding the dose and prompt further evaluation. Rash can indicate an allergic reaction, blood dyscrasias are serious blood disorders that can be life-threatening, and severe depression may worsen with haloperidol use. Choices A, B, and D are incorrect because drowsiness, lethargy, inactivity, dry mouth, nasal congestion, blurred vision, hyperglycemia, weight gain, and edema are common side effects of haloperidol that may not necessarily contraindicate its use but should be monitored and managed appropriately.

Correct Answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
