A patient prescribed warfarin is being taught about dietary restrictions by a healthcare provider. Which of the following foods should the patient be instructed to limit?

Correct Answer: B

Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Patients taking warfarin should limit foods high in vitamin K to maintain the medication's effectiveness and consistent dosage. Bananas, potatoes, and apples are not high in vitamin K and do not typically interfere with warfarin therapy.

Correct Answer: C

Rationale: The correct answer is monitoring the respiratory rate. Morphine can depress respiratory function, leading to respiratory depression or arrest. Therefore, closely monitoring the client's respiratory rate is crucial to detect any signs of respiratory distress. While blood pressure, heart rate, and temperature are important assessments, in this scenario, respiratory rate takes precedence due to the potential respiratory complications associated with morphine administration.

Correct Answer: C

Rationale: The correct response to a patient experiencing hypoglycemia is to administer 15g of fast-acting carbohydrates. This helps quickly increase the blood glucose levels in the patient, addressing the low blood sugar. Rechecking the blood glucose level in 15 minutes (Choice A) may delay necessary intervention, encouraging a high-protein snack (Choice B) is not recommended as it does not rapidly increase blood sugar levels, and administering glucagon if the patient is unconscious (Choice D) is typically done in severe cases of hypoglycemia when the patient is unable to eat or drink.

Correct Answer: B

Rationale: The correct definition of malpractice in the context of professional negligence is the failure to act in a reasonable and prudent manner by a professional. This choice is correct because malpractice occurs when a professional does not meet the standard of care expected in their field, leading to harm or injury to the client. Choices A, C, and D are incorrect because malpractice is specifically about the failure to meet professional standards of care, rather than personal standards, miscommunication within a healthcare team, or inadequate documentation of patient care.

Correct Answer: B

Rationale: The correct first action for the nurse to take when caring for a client with pneumonia who has a new prescription for antibiotics is to obtain a sputum culture. This is important to identify the specific bacteria causing the pneumonia before administering antibiotics. Administering the antibiotic immediately (Choice A) may not be appropriate without knowing the specific pathogen. Notifying the provider of the prescription (Choice C) is important but not the first action to be taken. Checking the client's allergy history (Choice D) is relevant but not the priority in this situation.

Correct Answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

Correct Answer: A

Rationale: Ensuring proper nutrition and hydration is crucial in preventing pressure ulcers in immobile patients. Adequate nutrition supports tissue health and repair, while hydration helps maintain skin elasticity. While turning the patient every 2 hours is important to prevent pressure injuries, it is not the primary way to address prevention. Using moisture barriers and providing special mattresses or padding are essential components of pressure ulcer prevention, but they are not as fundamental as ensuring proper nutrition and hydration.
