Question 1 of 5

Which antiparkinsonian drug is associated with the on-off phenomenon and the wearing-off effect?

Correct Answer: B

Rationale: The correct answer is B: Levodopa. Levodopa is associated with the on-off phenomenon and wearing-off effect in Parkinson's disease treatment due to fluctuations in its effectiveness over time. The on-off phenomenon refers to sudden and unpredictable changes in motor function, while wearing-off effect occurs when the medication's effects diminish before the next dose. Amantadine (A) is not typically associated with these phenomena. Benztropine (C) is an anticholinergic used for tremors and rigidity. Pramixole (D) is a dopamine agonist that can cause dyskinesias but is not primarily linked to on-off or wearing-off effects.

Question 2 of 5

Which of the ff. actions would the nurse include in the plan of care to reduce the symptoms of the patient who has vertigo?

Correct Answer: C

Rationale: The correct answer is C: Avoid sudden movements. Vertigo is a type of dizziness where a person feels like they're spinning or the world around them is spinning. Sudden movements can worsen vertigo symptoms. By avoiding sudden movements, the nurse can help reduce the patient's vertigo symptoms. Avoiding noises (A) may help with other conditions like migraines, but it is not specifically helpful for vertigo. Encouraging fluid intake (B) is important for overall health but does not directly address vertigo symptoms. Administering analgesics (D) may help with pain but will not address the underlying cause of vertigo. Therefore, choosing option C is the most appropriate action to include in the plan of care for reducing vertigo symptoms.

Question 3 of 5

When instructing the client diagnosed with hyperparathyroidism about diet, the nurse should stress the importance of which of the following?

Correct Answer: C

Rationale: The correct answer is C: Restricting sodium. In hyperparathyroidism, there is an excess of parathyroid hormone leading to increased calcium levels. Sodium can worsen calcium excretion, exacerbating the condition. Restricting sodium can help reduce calcium loss. A: Restricting fluids is not necessary unless the client has kidney issues. B: Forcing fluids may not be beneficial and can lead to fluid overload. D: Restricting potassium is not typically necessary unless the client has kidney issues.

Question 4 of 5

When administering spironolactone (Aldactone) to a client who has had a unilateral adrenalectomy, the nurse should instruct the client about which of the following possible adverse effects of the drug?

Correct Answer: C

Rationale: The correct answer is C: Menstrual irregularities. After a unilateral adrenalectomy, the remaining adrenal gland may be affected by spironolactone, leading to hormonal imbalances and menstrual irregularities. This drug is a potassium-sparing diuretic that can interfere with the production of aldosterone, affecting hormonal regulation. Breast tenderness (A) is not a common side effect of spironolactone. Increased facial hair (B) is associated with hirsutism, not typically seen with spironolactone. Hair loss (D) is more commonly associated with other medications like chemotherapy, not spironolactone.

Question 5 of 5

In assisting a physician to perform a thoracentesis to Mr. Sy, how should the nurse postion a patient with pleural effusion of the left lung?

Correct Answer: B

Rationale: The correct answer is B: sitting at the side of the bed with both arms resting on a locked overbed table. This position allows for better lung expansion and easier access to the thoracic cavity during the procedure. Sitting position helps in maximizing lung volume and facilitates drainage of pleural effusion. Arms resting on a locked overbed table helps the patient maintain a stable position and reduces the risk of movement during the procedure. Other choices are incorrect because supine position (A) may not allow for optimal lung expansion, high fowler's position (C) may not provide easy access to the thoracic cavity, and semi-fowlers position (D) may not facilitate efficient drainage of pleural effusion.
