In which of the ff clients will an MRI scan be contraindicated?
- A. Overweight clients
- B. Clients with metal implants in their body
- C. Clients over the age of 60
- D. Clients with brain tumor CARING FOR CLIENTS WITH CENTRAL AND PERIPHERAL NERVOUS SYSTEM DISORDERS
Correct Answer: B
Rationale: An MRI scan uses strong magnetic fields and radio waves to create detailed images of the body's internal structures. Clients with metal implants in their body, such as pacemakers, artificial joints, or other metallic objects, may experience potential risks and complications during an MRI scan. The strong magnetic field can interact with the metal in the body, causing movement, heating, or potential damage to the surrounding tissues. Hence, it is contraindicated to perform an MRI scan on clients with metal implants to avoid harm and ensure their safety.

Which of the ff precautions must a nurse take while caring for clients with HIV/AIDS to reduce occupational risks?
- A. Transport specimens of body fluid in leakproof containers
- B. Seek prescription for a fusion inhibitor to reduce risk of infection
- C. Avoid administering IV drugs
- D. Avoid cleaning the clients room, esp cleaning urine, stool, or vomit
Correct Answer: A
Rationale: When caring for clients with HIV/AIDS to reduce occupational risks, a nurse must take precautions to minimize the risk of exposure to body fluids that may contain the HIV virus. Transporting specimens of body fluid in leakproof containers helps prevent accidental spills or leakages that could lead to exposure. Proper handling and containment of body fluids are essential to reducing the risk of transmission of HIV to healthcare workers. This precaution is in line with standard infection control practices to ensure the safety of healthcare providers and minimize the risk of occupational exposure to bloodborne pathogens like HIV.
An infant has been diagnosed with cow's milk allergy. What are the clinical manifestations the nurse expects to assess? (Select all that apply.)
- A. Pink mucous membranes
- B. Vomiting
- C. Rhinitis
- D. Abdominal pain

Which of the following is an early sign of anemia?
- A. Palpitations
- B. Pallor
- C. Glossitis
- D. Weight loss
Correct Answer: B
Rationale: Pallor, or paleness of the skin, is an early sign of anemia. Anemia occurs when there is a decrease in the number of red blood cells or the amount of hemoglobin in the blood, resulting in reduced oxygen supply to the body's tissues. This lack of oxygen can cause the skin to appear pale due to decreased blood flow. Other common symptoms of anemia may include fatigue, weakness, shortness of breath, dizziness, and cold hands and feet. Palpitations, glossitis, and weight loss are not typically early signs of anemia.
The nurse is explaining the action of insulin to a newly diagnosed diabetic client. During the teaching, the nurse reviews the process of insulin secretion in the body. The nurse is correct when stating that insulin is secreted from the:
- A. adenohypohysis.
- B. alpha cells of the pancreas.
- C. beta cells of the pancreas.
- D. parafollicular cells of the thyroid.
Correct Answer: C
Rationale: Insulin is secreted from the beta cells of the pancreas. These specialized cells are located in the islets of Langerhans within the pancreas. When blood glucose levels rise after eating, beta cells release insulin into the bloodstream to help regulate glucose levels by allowing cells to take in glucose for energy or storage. Insulin also helps lower blood sugar by promoting the conversion of glucose to glycogen in the liver and muscles. Therefore, the nurse is correct in stating that insulin is secreted from the beta cells of the pancreas.
A nurse prepares to administer the medication in which muscle site?
- A. Deltoid
- B. Triceps
- C. Vastus lateralis
- D. Biceps
Correct Answer: C
Rationale: The nurse prepares to administer the medication in the vastus lateralis muscle site. This site is located on the thigh and is commonly used for intramuscular injections in infants, toddlers, and smaller children. It is preferred for its large and easily accessible muscle mass, making it suitable for injections. This muscle site is also less painful and has fewer major blood vessels and nerves, reducing the risk of complications during injection.
