A client with rheumatoid arthritis has just been prescribed methotrexate. What teaching should the nurse include?

A. Take the medication on an empty stomach.

B. Report any signs of infection, such as a sore throat.

C. Take folic acid supplements to prevent anemia.

D. Use sunscreen to prevent photosensitivity.

Correct Answer: D
Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.

An adult male is brought to the emergency department following a motorcycle accident, presenting with periorbital bruising and bloody drainage from both ears. Which assessment finding warrants immediate intervention by the nurse?

• A. Rebound abdominal tenderness.
• B. Diminished bilateral breath sounds.
• C. Rib pain with deep inspiration.
• D. Nausea with projectile vomiting.

Correct Answer: D
Rationale: In this scenario, the patient's presentation with periorbital bruising and bloody ear drainage suggests a basilar skull fracture. Projectile vomiting, as described in choice D, is concerning for increased intracranial pressure due to the skull fracture. This finding warrants immediate intervention to prevent further neurological compromise. Choices A, B, and C are not the priority in this situation. Rebound abdominal tenderness (choice A) is indicative of intra-abdominal injury but is not as urgent as managing potential intracranial issues. Diminished breath sounds (choice B) and rib pain with deep inspiration (choice C) may suggest underlying chest injuries, which need attention but are not as immediately life-threatening as increased intracranial pressure.

A client with hypothyroidism is prescribed levothyroxine. What symptom indicates that the dosage may need adjustment?

• A. Increased appetite and weight gain.
• B. Increased sensitivity to cold and dry skin.
• C. Increased heart palpitations and sweating.
• D. Increased shortness of breath and rapid heart rate.

Correct Answer: B
Rationale: Increased sensitivity to cold and dry skin may indicate that the dosage of levothyroxine is too low, requiring adjustment. This symptom is typical of hypothyroidism when the body's metabolism slows down, leading to feeling cold and having dry skin. Choices A, C, and D present symptoms more commonly associated with hyperthyroidism, where the body is in a state of overactivity, leading to weight loss, increased heart rate, and sweating. Therefore, these symptoms would not indicate the need for dosage adjustment in a client with hypothyroidism.

A client with pheochromocytoma is admitted to the hospital. Which intervention has the highest priority?

• A. Monitor blood pressure frequently
• B. Start intravenous fluids at a fast rate
• C. Administer pain medication to reduce discomfort
• D. Give antihypertensive medications as prescribed

Correct Answer: B
Rationale: The correct answer is B: Start intravenous fluids at a fast rate. In a client with pheochromocytoma, the highest priority intervention is to ensure adequate intravascular volume before initiating any other treatment. This helps prevent a sudden drop in blood pressure that can occur due to the release of catecholamines during tumor manipulation. While monitoring blood pressure frequently is essential, ensuring adequate intravascular volume takes precedence. Administering pain medication and antihypertensive medications are important but are not the highest priority in the initial management of pheochromocytoma.

A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct Answer: B
Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.
