A patient with Parkinson's disease is prescribed levodopa. What dietary modification should the nurse suggest to the patient?
- A. Increase intake of vitamin C.
- B. Limit foods high in protein.
- C. Avoid foods rich in fiber.
- D. Increase sodium intake.
Correct Answer: B
Rationale: The correct answer is B: Limit foods high in protein. Levodopa competes with amino acids for absorption in the small intestine, so consuming high-protein foods can reduce its effectiveness. Limiting protein intake can help maximize the absorption and efficacy of levodopa. Increasing vitamin C (option A) is not directly related to levodopa metabolism. Avoiding fiber (option C) is not necessary for levodopa therapy. Increasing sodium intake (option D) is not indicated for levodopa treatment in Parkinson's disease.

A patient with asthma is prescribed a corticosteroid inhaler. What is the most important instruction to give to the patient?
- A. Use the inhaler only during asthma attacks.
- B. Rinse the mouth after using the inhaler.
- C. Take a double dose if symptoms worsen.
- D. Avoid using a spacer with the inhaler.
Correct Answer: B
Rationale: The correct answer is B: Rinse the mouth after using the inhaler. This instruction is crucial because corticosteroid inhalers can lead to oral thrush, a fungal infection in the mouth. Rinsing the mouth helps prevent this side effect.
A: Using the inhaler only during asthma attacks is incorrect as corticosteroid inhalers are typically used regularly to manage asthma symptoms.
C: Taking a double dose if symptoms worsen is dangerous and can lead to overdose. Patients should follow the prescribed dosage.
D: Avoiding using a spacer with the inhaler is not a universal instruction. Spacers can actually improve the effectiveness of the medication delivery.
A patient with chronic obstructive pulmonary disease (COPD) is experiencing severe dyspnea. What position should the nurse encourage the patient to assume?
- A. Supine
- B. Prone
- C. High Fowler's
- D. Trendelenburg
Correct Answer: C
Rationale: The correct answer is C: High Fowler's. This position helps improve lung expansion and breathing efficiency by maximizing chest expansion. Sitting upright reduces pressure on the diaphragm, allowing for better ventilation. Supine (A) position can worsen dyspnea by restricting lung expansion. Prone (B) position is not ideal for COPD patients as it can hinder breathing. Trendelenburg (D) position, where the patient's feet are elevated above the head, can increase pressure on the diaphragm and impair breathing, making it inappropriate for a patient experiencing severe dyspnea.
A patient who is receiving chemotherapy for breast cancer develops thrombocytopenia. What should the nurse include in the care plan?
- A. Encourage light exercise.
- B. Avoid intramuscular injections.
- C. Do not administer aspirin.
- D. Use a soft toothbrush for oral care.
Correct Answer: B
Rationale: The correct answer is B: Avoid intramuscular injections. Thrombocytopenia is a condition characterized by low platelet count, which can lead to impaired blood clotting. Intramuscular injections can cause bleeding and bruising due to the decreased ability of blood to clot. Therefore, it is crucial to avoid invasive procedures like intramuscular injections to prevent excessive bleeding in patients with thrombocytopenia. Encouraging light exercise (choice A) can be beneficial for overall health but may not directly address the risk of bleeding. Avoiding aspirin (choice C) is important as it can further increase the risk of bleeding. Using a soft toothbrush for oral care (choice D) is a good practice, but it does not directly address the risk associated with intramuscular injections in patients with thrombocytopenia.
A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?
- A. Administer regular insulin intravenously.
- B. Give oral hypoglycemic agents.
- C. Administer sodium bicarbonate.
- D. Provide a high-calorie diet.
Correct Answer: A
Rationale: The correct answer is A: Administer regular insulin intravenously. In DKA, the priority is to lower blood glucose levels and correct acidosis. Regular insulin intravenously is the fastest way to reduce blood glucose levels. Oral hypoglycemic agents (B) are not effective in DKA. Sodium bicarbonate (C) is not routinely recommended in DKA as it may worsen acidosis. Providing a high-calorie diet (D) is not appropriate as the focus should be on treating the underlying condition first.
An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?
- A. Corticosteroids
- B. Gamma globulin
- C. Hepatitis B vaccine
- D. Fresh frozen plasma
Correct Answer: B
Rationale: The correct answer is B: Gamma globulin. Gamma globulin contains antibodies that can provide immediate passive immunity against hepatitis B virus. Administering corticosteroids (A) would not protect against hepatitis B infection. Hepatitis B vaccine (C) is used for prevention, not immediate protection. Fresh frozen plasma (D) does not contain specific antibodies against hepatitis B.
